Seeing as 4Sword was having a go at me for not replying to a C++ programming PM from him due to my unfortunate state of being asleep. I figured I would make this topic to help out a bit.
If you have any question about programming (any language you choose) that are to trivial to warrent their own topic; syntax errors, not unstanding certain concepts, etc. Post them here and I'll make sure either I or one of the other programmers on this forum gives you a reply.
When posing a question please include relavent information (source code that produce the error, etc) to help make answers faster.
(Be aware however this isn't a 'How do I build blank engine' topic, those questions should be in their own topics).
Have at it.

How do I built engine?
(I just had to...)
Edit: Maybe I should make this a more serious post.
I'm interested in learning a language (GameMaker is... meh), what would be best for me to start? (Not really much knowledge of previous languages.... BASIC BASIC GML THAT'S IT.)

Simplest way of getting into programming is probably by using a BASIC varient, BlitzMax (www.blitzbasic.com), Free Basic (http://www.freebasic.net), .etc, .etc. They tend to have a more abstract higher level interface than languages like C++, and tend to take the burden off the programmer for things like memory management, bounds checking, .etc, .etc. Meaning you can get to do the things you want faster without having to worry about any of the tedious 'behind-the-scene' stuff.
Once you've chosen a language the best way of really getting to grips with it (and importantly the logical methodoligy that goes behind it) is simply through experimentation, try creating a few simple but ambitious games, you may well fail but I can guarantee you will learn more about the language each time you do. Stick with the simple aspects of the language (IF statements, While statements, .etc) while your learning then once you've got the basics down try skimming through some language references and try out some of the more advanced stuff using the same experimentation method, after a while you will being to expand your knowledge of programming a great deal and will be able to do larger scale projects on your own.

QBasic is ancient and irrelivent to the current programming world though, it won't really help you start, and will probably leave you with bad habbits (goto and such).
Javascript is just plain slow, and requires a browser to run.

I basically suggested those so he could easily grasp some ground rules of programming. They have good syntax that is somewhat similar in other languages. It seems he needs to start with a book for dummies, if you know what I mean.

Just to get so,me basics down. Besides, who really does not have a browser?

Again, just to get the dirt basics...

My question:
I'm am trying to find an alternate to <embed src="lol.swf" /> any help? needs to be XHTML 1.0 Transitional
(not sure if we can double post in this topic...)
-
I guess:
<object type="application/x-shockwave-flash" data="yourclip.swf" width="x" height="x" id="myclip">
<param name="movie" value="yourclip.swf" />
<param name="quality" value="high" />
Alternative content (images, text, etc.)
</object>could work fine.
If you want more informations about including any sorts of video files (WMP, QuickTime, Flash etc.) without embedding them, read byebyeembed (http://alistapart.com/articles/byebyeembed). ;)

Infini, actually the QuickBASIC community also greatly discourages the use of goto. Older versions of FreeBASIC were essentially modern versions of QuickBASIC, but now it's moved on from that stage by quite a bit.

QuickBasic != QBasic just so you know :). QBasic is a derived dialect written by microsoft. Either way thats not important, its still ancient :S.
-
I know, but most people who grab QBasic usually get QuickBASIC afterwards or accidentally anyway, and all the QBasic communities I've seen generally don't care if you use Q or Quick. The words have practically become interchangeable amongst them, and since they were where I started learning programming, I've been using them interchangeably.

Dosen't matter TheDarkJay, this isn't a debate topic.
-
I know, I just always will defend myself when approached with even minor criticism. It's an instinctive thing :)
Anyway, back to the questions!
Actually, they is something I've been wondering. Do operating systems clean up after programs if memory isn't freed by the program? I mean, if I call a new object and don't delete it, when the program closes is that object going to be taking up memory in the RAM until the OS shuts down, or is it going to be gone?
Don't worry, I know all allocated memory should be deallocated in a program, this is just morbid curiosity speaking :)

Yes when a program finishs the entire working set allocated to it is disposed and recycled.

Nearly everyone of them does, but do not depend on it. You should not just assume that any mess you make will be cleaned up when the program exits. Instead, you should try to clean up for yourself.
-
I know that. Hell, I usually make sure that happens during the testing period with two global integers and a few macros counting the number of new and delete calls, making sure the numbers match by outputting them when the program closes.

no error it just doesn't work...
I put <?PHP inlcude 'file.php'; ?>
and the page stopped rendering at that point , which means something is wrong with the script.
-
As far as I can tell your code is correct. And stopping rendering dosen't mean an error has neccessarally occured, if a script error has occured a description will normally be output to the browser. Do you have it uploaded anywhere where I can check it?

Works fine. Your problem was that you didn't escape a ' on line 62.
echo '<p> FAQ's </p>';
Should have been;
echo '<p> FAQ\'s </p>';
You may want to enable error reporting in your php script in future, using something like this;
ini_set("display_errors","2");
ERROR_REPORTING(E_ALL);
Or you can just edit the php.ini file.

Thank you! <3
EDIT: Ok new problem, type ?do=services&actionid=0001
It displays Services, then all of the options then an error message when it is only supposed to display the first option...
I might have done something dumb like string = string rather than string == string... I'll check
-
You haven't put break statements at the end of each switch branch. If you don't do that then control will continue on to the next block;
eg.
switch(x)
{
case 0:
/// Blah blah blah
break;
case 1:
/// Blah blah blah
break;
default:
/// Blah blah blah
break;
}

LOL I NEED TO SLAP MYSELF :P

New problem (Sorry my area is not Websites... But I am learning fast!)
anyway,
Removed
Umm what?

Post icons.xml please.

Removed
lol I am using this topic as my "I'm too lazy to figure it out, so I will tell others and hope they figure it out while I check out Diablo 3". Sorry about that...
-
I think its because the & symbol is used as a escape sequence starter in XML, you need to replace all arbitary & symbols with &.
As for using this topic to be lazy, GTFO!

Not that it concers you, but I removed it because it was huge and was screwing up the template.

lol, my speciality. If you want an explanation on this grab my MSN (chleonard@aol.com), its far to complicated to explain on a forum. A warning though, compiler design is considered one of the most complex aspects of programming, unless you want to spend a long time getting to grips with it, forgot it :P.

Well, what exactly are you able to do with that kind of knowledge?
-
Well, what exactly are you able to do with that kind of knowledge?
make your own programming languages,
build your own compilers for different langauges, and further your understanding of the microcomputer
BTW Infini maybe you can send MG-Zero that book you were talking to me about?
-
Interesting, I'll look into it =)

Be sure to ask infini for a book to get you started!

I'd say very yes to a compiler class. Not so much so you can 'make your own languages', or what not. For the sole purpose of just getting down and dirty, thinking about the core concepts behind a compiler. When you think about how a compiler is written, it can, and will make you think much differently when you're coding. Compilers are beautiful, but sometimes fickle creatures. Knowing the basic idea of how they work can only help you.
-

Well I'm gonna be taking it in college, so i'm not gonna bother with a head start or anything.
-
That sounds like an interesting class, heck I'd take it just for the sake of taking it. It's gonna be geared more towards lower level programmers, ASM and C style. If you're more into VB or C#, it may not be for your tastes, but there's never any harm in learning something new.

Let's play with some operator overloading..Say I have..
class BaseClass
{
//blah blah blah
};
class newclass1 : public BaseClass
{
//blah
};
class newclass2 :public BaseClass
{
//blah
};
If I overload an operator (lets say + for the hell of it) to work with the baseclass, will the overloaded operator work with the derived classes as well? Or will I have to overload it for each derived class?

For most operators, yes. However a quirk of the C++ standard is that implicitly declared operators (eg. Ones declared internally by the compiler) overrule any inhereted operators, the only one I can think off off hand that has this behaviour is the assignment operator.

Don't we all just love linker errors? specifically
fatal error LNK1169: one or more multiply defined symbols found
Yea, I can't get rid of this one. I declared an instance of a class in a header file and it came up. But it works fine if I declare it in a .cpp file (I need it in the header though..). I've checked about 3 or 4 times over my preprocessor commands for #include misuses, I can't seem to find any though. I have inclusion guards on all of my header files as well.
EDIT: http://pastebin.com/m1d3e24f4 code is on here (it's a lot btw) I seperated each file with a comment of the file name. Min also went through it, he thinks it's a problem with command.h.
-
can't you just declare it in a cpp file and then have an extern in the header file?
-
Windy is actually correct, for static variables you need to declare them in the H and implement them within the CPP file. Its just a quirk of the C++ standard, it will work perfectly fine though. Have a look at the zfgsdk source and see how I've declared static variables in that (CGameEngine.cpp for example).
-
Alright, i'll take a look.

I v e been taking a look into xna , i got into a bit , but i want to know whats best to use for 2d games using C++ , (like directX).Also one of the biggest things that confuses me is making your own map editor. I want to know if you know any good tuts or books on subject like that?
-

Thats a matter of opinion, they all provide an interface to do the same basic thing (render textured polygons), which one you choose to use is entirely up to you. I personally prefer OpenGL though, far less obtuse and more portable.
Also one of the biggest things that confuses me is making your own map editor. I want to know if you know any good tuts or books on subject like that?
I doubt it, most people would assume that by the time you are trying to make map editors that you alreayd have the skills required to do so. I doubt many people have written tutorials about them. Though if your lucky you may find a few on google.
-
do you know where i can find tutorials on OpenGL, i know on map part , why i just need to learn the language not just game development
-
OpenGL isn't a language, it's used with a language. Make sure you have a solid understanding of the language you want to use it with.
http://www.swiftless.com/tutorials/opengl/opengltuts.html
Try these, I haven't looked at them yet, but they should get you started.

It's not exactly what you want, but check out mappy (http://www.tilemap.co.uk/mappy.php), last time I checked it, the source code was available.

How do I remove a header in PHP
OR disable chunk transfer encoding?
-
How do I draw text in GM7? I've tried this, but no text appears. Can anyone help here?
-
GM will only draw things that are put in the draw event (there are other ways, but they are really only useful for surfaces). If you are using the draw event in an object with a set sprite, the draw event will override the normal drawing of the sprite, so you have to manually redraw the sprite in the draw event, as well.
-
I thought it used the font you set. Is there any reason to add a font to your resources then?
-
How do I remove a header in PHP

Use the header() function. Heres the first google result to help you;
http://www.expertsrt.com/tutorials/Matt/HTTP_headers.html
-
I thought it used the font you set. Is there any reason to add a font to your resources then?
Wait, what? Yes, you set the drawing font and then draw text, all in the draw event. You add a font to resources so you can set the drawing font to that font.
-
Is there any way to choose a color? Or is that in the event as well?
-
You can set the drawing color using draw_set_color, or you can draw text with a color gradient, using draw_text_color.
-
I'm trying but it isn't working. Should I used When key is pressed or just key? And any suggested keys that would work for it? Alos, how do I set strings? I can't figure out how to do that.
-

http://www.expertsrt.com/tutorials/Matt/HTTP_headers.html
so if I put
<?PHP
header('Transfer-Encoding: none');
?>
That should disable chunked encoding since I am replacing chunked with none?
-
Should do, yup.
-
Should do, yup.
Nope
result:
Transfer-Encoding: none, chunked
can you disable it on certain pages Infini?

Quick question, is there a way in C# (like a function) to see if a number is in a 5 number range of another? Like number1.InRangeOf(number2, 5); (obviously doesnt exist). I did the maths way by taking a number a way but it's ugly as !@#$%. Any help plz.
-
There is no quick way but its not difficult exactly difficult. Something like this will work;
bool InRange(float number1, float number2, float range)
{
return math.abs(number1-number2) <= range;
}

Oh my f--..... Thank you <3

How do I make a server tool with .net c++ and socks?
I am having a hard time understanding this.... (yes I used google)
-
I made this a while ago as I required a method for 2 programs to communicate with each other so I could read commands sent by SOC dll that OoL was using, OoL in this case was the "client" and it would connect to this server I had set up and send the commands to me that the SOC dll was executing.
Basically it went something like this.
Declare this somewhere in your class
private: static System::Net::Sockets::Socket^ listener;
Create the connection and allow it to begin accepting "clients", in this particular piece of code we're setting it up to accept connections using TCP/IP on port 8888, BeginAccept allows us to set up a callback to which we can deal with "clients" that connect asynchronously.
listener = (gcnew System::Net::Sockets::Socket(System::Net::Sockets::AddressFamily::InterNetwork, System::Net::Sockets::SocketType::Stream, System::Net::Sockets::ProtocolType::Tcp));
System::Net::IPEndPoint^ localEndPoint = (gcnew System::Net::IPEndPoint(System::Net::IPAddress::Any, 8888));
try
{
listener->Bind(localEndPoint);
listener->Listen(10);
listener->BeginAccept(gcnew System::AsyncCallback(&AcceptCallback), listener);
}
catch (Exception^ e)
{
System::Windows::Forms::MessageBox::Show(e->ToString());
}
Function that is ran when a "client" attempts to connect to the server, in this particular piece of code we accept the connection and set up the server to begin receiving data from this "client"
private: static System::Void AcceptCallback (System::IAsyncResult^ result)
{
mySocket = (System::Net::Sockets::Socket^) result->AsyncState;
myHandler = mySocket->EndAccept(result);
myHandler->BeginReceive(buffer, 0, buffer->Length, System::Net::Sockets::SocketFlags::None, gcnew AsyncCallback(&ReceiveCallback), listener);
}
Is the function that is run while the server begins receiving data from the client, in this particular case all i'm doing is displaying the message recieved in a message box.
private: static System::Void ReceiveCallback (System::IAsyncResult^ result)
{
array<System::Byte>^ bytes = safe_cast<array<System::Byte>^, result->AsyncState>;
int byteCount = mySocket->EndReceive(result);
if(byteCount>0)
{
System::String^ received = System::Text::Encoding::ASCII->GetString(buffer, 0, byteCount);
System::Windows::Forms::MessageBox::Show(received);
}
}

Create the connection and allow it to begin accepting "clients", in this particular piece of code we're setting it up to accept connections using TCP/IP on port 8888, BeginAccept allows us to set up a callback to which we can deal with "clients" that connect asynchronously.
listener = (gcnew System::Net::Sockets::Socket(System::Net::Sockets::AddressFamily::InterNetwork, System::Net::Sockets::SocketType::Stream, System::Net::Sockets::ProtocolType::Tcp));
System::Net::IPEndPoint^ localEndPoint = (gcnew System::Net::IPEndPoint(System::Net::IPAddress::Any, 8888));
try
{
listener->Bind(localEndPoint);
listener->Listen(10);
listener->BeginAccept(gcnew System::AsyncCallback(&AcceptCallback), listener);
}
catch (Exception^ e)
{
System::Windows::Forms::MessageBox::Show(e->ToString());
}
Function that is ran when a "client" attempts to connect to the server, in this particular piece of code we accept the connection and set up the server to begin receiving data from this "client"
private: static System::Void AcceptCallback (System::IAsyncResult^ result)
{
mySocket = (System::Net::Sockets::Socket^) result->AsyncState;
myHandler = mySocket->EndAccept(result);
myHandler->BeginReceive(buffer, 0, buffer->Length, System::Net::Sockets::SocketFlags::None, gcnew AsyncCallback(&ReceiveCallback), listener);
}
Is the function that is run while the server begins receiving data from the client, in this particular case all i'm doing is displaying the message recieved in a message box.
private: static System::Void ReceiveCallback (System::IAsyncResult^ result)
{
array<System::Byte>^ bytes = safe_cast<array<System::Byte>^, result->AsyncState>;
int byteCount = mySocket->EndReceive(result);
if(byteCount>0)
{
System::String^ received = System::Text::Encoding::ASCII->GetString(buffer, 0, byteCount);
System::Windows::Forms::MessageBox::Show(received);
}
}
:-[ :-[
Yes, I got about -1% of that...
-
Yes, I got about -1% of that...
It's a basic .NET server application (Managed C++, in this case) that uses asynchronous sockets to receive data from clients, then shows a message box saying what the data received was.
-
I don't mean to sound rude but if you don't know then perhaps you shouldn't be trying it. Look up information on sockets to get an understanding of it, and then just look for tutorials for sockets in managed C++...
If you know what you're doing then you should know what to look for to solve your problem.

Ok, but I guess I wasn't clear enough.
I really don't know how to get this started.
I have done stupid stuff like
#include <winsock.h>
{
WSADATA wsaData;
if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0) {
fprintf(stderr, "WSAStartup failed.\n");
exit(1);
}
then stared at the code and was like
... huh? ... now how do I transmit crap and do this and this...
Sorry, I am probably a lazy programmer
EDIT:
Ok, I read some crap, now maybe this narrows down to the bone. I do not get the process of the server receiving, say the x,y coordinates of players, and displaying it to other clients, nor did I find a tutorial for this type of stuff. Basically if you must know, I am creating a server tool for a PSP game, I want to make it in c++ .net and socks, windows, VC 2008 Express.

Got a simple question for ya with function overloading.
Let's say I have..
typedef short int Type1;
typedef short int Type2;
If I overloaded a function like so..
int calc(Type1 var, int var2);
int calc(Type2 var, int var2);
Would it work? Reason I'm wondering is becuase Type1 and Typ2 are both short for the same thing. And yes, I have a reason for wanting to do this xD

While it might be possible (I don't know the real answer), it is actually not logical. DICKBUTT works by having your browser fetch data from the HTTP server... if you are just viewing your html by opening the file in Firefox, obviously there is no server.
Consider setting up a local development HTTP server like xampp (http://www.apachefriends.org/en/xampp.html) (but keep in mind that it is meant for development only!).

Oh sorry, I'm running apache 2.2 server locally. PHP works fine with it.

Ok, I have a "click here to enter page" when you enter the url has no "#" in it.
I have javascript that checks for that in the url, if it is there it loads content.
now everything is good but my links are href'd to # to avoid loading the same content. but when I refresh and # is present in the url. nothing happens. :/ how do i fix this?
BTW I have DICKBUTT requesting maincontent.php to get content to display on page.

Probably some dumb question...
$file = fopen('news/data.txt', 'w+'); //open the news database, I have tried a+, r+, x+ : /
$len = filesize($file);
$exist = fread($file, $len); //read the contents
$entry = $_POST['content']; //get the new entry
$newcontent = $entry.$exist; //merge the two
fwrite($file, $newcontent); //write the newly created text
fclose($file);// close it
echo "You News has been Posted! <br />"; //Tell user...
The problem? Fread does not return the contents of that file!
What is wrong with it?
-
w+ opens and removes all contents of the file. You want to use r+. Additionally, filesize takes a filename, not a file resource.
$file = fopen('news/data.txt', 'r+'); //open the news database, I have tried a+, r+, x+ : /
$len = filesize('news/data.txt');
$exist = fread($file, $len); //read the contents
$entry = $_POST['content']; //get the new entry
$newcontent = $entry.$exist; //merge the two
fwrite($file, $newcontent); //write the newly created text
fclose($file);// close it

How do you set a HTML <form>'s action to do javascript?

A form can only submit data to a page. You can use onsubmit to do stuff before the form gets sent, but I'm guessing you're using DICKBUTT and never intending to send the form to begin with you may as well just have a button with an onclick.

If you use this;

and return false from the calling function, your javascript will be executed and the form will not be submitted.

Okay, so I'm on Linux and am using OpenGL and the X Window System. I can quite easily create windows which display via OpenGL. Most easily indeed. However, how do I create a 'full screen' program using the X Window System? Countless attempts at google have shown me nothing. And do I have to do anything extra with OpenGL to get it to work full screen on the X Window System?
I'm not asking for anyone to go into this in great details, just point me in the right direction please :)
-
google gave me: (SDL_OPENGL | SDL_FULLSCREEN)
-
google gave me: (SDL_OPENGL | SDL_FULLSCREEN)
Did he ever once mention SDL?
I'm not sure whether or not you're using GLUT, but on the assumption that you are, this may help:

Don't spam.

Nope. I'm using the X Window System for window creation and the required OpenGL extension (GLx). No other libraries. No SDL, no GLUT, no GLFw, just OpenGL, GLx and X11.
-
Try looking up information on the override_redirect attribute of the XSetWindowAttributes structure. As far as I know, it lets you skip the "middle man" (which would be the window manager). I'm sorry that I can't help you more.

Probably a dumb question:
How do I make a object in BlitzMax move in a certain direction?
For more Info: I have a character that rotates to the mouse, I want the bullets to go towards the mouse.
-
Are you asking for a move towards point script?
Im not sure if this is right,but
Object.y -= (sine(512degree_angle measurement_between_Object_and_mouse)/256)
Object.x += (cosine(512degree_angle measurement_between_Object_and_mouse)/256 )
It a formula, not actual code, and I beleive the "/256" part may be wrong.
Hope this helped ;D
~LynkW- Wow, Constructive.
-
Moving at an angle is done as follows
x += cos(angle)*speed
y += sin(angle)*speed
You may need to convert the angle to radians first (radians = angle * pi / 180).
If you want a lot of bullets I suggest creating a lookup table (I assume Blitmax just does the raw calculations), because trigonometry functions can be a bit slow.

I want to center the point.

just a quick question, what would the best .net framework be to work with and target a c# application?
-
Darklight: My personal preference for C# is .NET 2.0. It contains all the nice and well-needed updates (generic classes, etc...) and is the last version to be supported on the old Windows operating systems (Windows 2000/ME/98).
The newer versions appear to be mainly targeted at Vista (with most of the additional features being for Vista compatibility). There doesn't appear to be any major functionality that you would lose by using .NET 2.0, and you can potentially support the older versions of Windows if you have to.
It all depends on what you need.

yeah, I should have really said I wanted to support at least XP/vista.
Thanks, I just wasn't sure how much functionality I'd loose by using an older version of .NET.

No the LoadImage is correct, startup.png is located in GFX.
BTW, Infini, this is my 2nd time using it, not as my second time attempting, this is actually my second time opening MaxIDE.
It has a bunch of errors, probably all of those useless global declarations, but I will fix that later.

It may be there but is it being loaded. Stick a debugstop directly after the loadimage call and check that titleImage is actually valid.

Fixed, it was that driver declaration -_-.

Is there any way to stretch an image to a certain width in BlitzMax? the forums and Google don't seem to know.

SetScale?

SetScale?
That didn't work. Probably should have said that I tried SetScale. SetScale uses a percentage and I want pixel width not percentage width.
EDIT: I fixed it by making a formula to convert the percentages to pixels >__>

u_u. I think thats obvious. You just use something like this;
setscale(float(new_width) / float(image_width), float(new_height) / float(image_height))

Got some array and pointer dickery going on here..

mainData[dataCount] = data; //put in the new data
delete tempData; //get rid of the temp data

2 functions there using a pointer and an array to hold some data and output it. Going by the main function, the output should be:

Is there a way to convert a char value into into an int, double, or float in C++? I don't mean grabbing it's ascii value, I mean turning it into an actual number. I.E. if the char value was "1.5", is there a way to put that value into a double? I basically need a cdbl() function like in Basic..

What it does: Basically, I put <body onLoad="INI();"> to make sure that when someone visits my site they get content loaded.
Now it works perfectly in FF <3
Now IE doesnt load anything, it has my outputted text "Loading..." and never loads anything.
But I have gotten the DICKBUTT to work in IE, so for example I load my site and click on a menu link, it loads perfectly in both browsers.
For those alerts,
When you first get to my site the alerts go up to 5, so
thing.open("GET", url, true);
is wrong for some reason.
The alert in the DICKBUTT() function returns "[object]" which is true for all of the pages that have working DICKBUTT, so that is not the problem.
Why can't IE load at the initial view? Is there something wrong with my code?

I am currently trying to put a simple authentication system in the mean time for my shoutbox.
I decided that I want to use tripcode because it was easy.
I have one question:
How do I convert UTF 8 to Shift JIS? in Javascript? is it possible? I haven't gotten any results from google... and the code that I have seen is done in Ruby.
-
lol, why in hells name do you want japanease character encoding.
Anyhow I'm not sure, haven't got enough information about it. Post the ruby code, might be helpfull.
-
The tripcode function works as follows:
1. Convert the input to Shift JIS.
2. Replace the characters &, <, >, ", and ' with &, <, >, ", and ' respectively. Some implementations replace other characters as well, these are the most common ones.
3. Generate the salt as follows:
1. Take the second and third characters of the input with H.. appended to it.
2. Replace any characters not between . and z with ..
3. Replace any of the characters in :;<=>?@[\\]^_` with the corresponding character from ABCDEFGabcdef.
4. Call the crypt() function with the input and salt.
5. Return the last 10 characters.
Some buggy implementations don't convert to Shift JIS. The original implementation of tripcodes only used the last 8 characters.
Well, since I don't really know anything about Tripcode other than the fact that it differentiates users on messages boards etc. I decided to follow Wikipedia
Anyway here is the ruby (sorry, it was python :P) code:
import re, string, crypt
def mktripcode(pw):

It doesn't really help since it has a function to do it...

Seriously, why? The conversion to japanease just seems so incredibly pointless. Not to mention you can generate a tripcode equivilent in so many easier ways.

I was just following the Wikipedia algorithm because I don't know better :P
Anyway, what else can I do? Convert it to another encoding type?

The only reason I can think that you would wish to follow wikis algorithem is so that tripcodes are consistent across all other sites that use the same algorithem. But to be fair, when is that going to directly matter to you? Why not just hash the users password concatinated with a salt, and extract the first 8 or so characters from the result.

Quick question:
Say I have 1 .Net program running. This application has 1 input box and 1 output box.
Is there ANY possible way I can get the text in the output box and put text in the input box using a program I made?
Preferably VB...
-
inputBox.Text = outputBox.Text;
???
-
inputBox.Text = outputBox.Text;
???
This but without the semi colon.
-
I believe he's referring to doing it from an external application.
-
In that case. Quite easily using the winapi functions. However it depends on how the program is configured. Some (such as MSN) use windowless controls which makes it impossible (well not impossible, but dam hard) for outside applications to directly modify the controls.
-
Woops, I just read my post and let me clarify...
1 program running, has input box and output box.
I want to make another program that will read the output of Program 1 and input something into Program 1's input box.
Preferably VB.
Now with winapi, would it make it harder if I tried to do it with a VB application inputting into a .NET application?
I don't think the program has some super !@#$% protection, its a simple server application so that shouldn't be a problem. :)
-
Now with winapi, would it make it harder if I tried to do it with a VB application inputting into a .NET application?
Nope. .NET or VB, still uses the same windows framework.
I'll write an example when I get back from college.

Hi budgieboy, welcome to the forum!
I'm not an expert, but have done something similar recently and will try to pass on what I learnt about sending keystrokes to other applications. There are several ways to send keystrokes from a VB program :
1) Use the built-in VB 'SendKeys' statement. You call this and pass a string which is input to the current active window. This is the easiest to code but you have to find and active your chosen window before you can call SendKeys. Also, many people (including me!) have had problems with SendKeys and it doesn't seem to work in some situations.
2) Use the SendInput API. This can be used to simulate both Mouse and Keyboard input to the current active window. This is more difficult to code and requires other API's to move and copy memory around before you call SendInput. This method seems to work for most people, but I had some problems with it (nothing wrong with the API or my code, but the type of application I was sending input to ).
3) Use the SendMessage or PostMessage API. Any Windows message (e.g. keyboard, mouse, paint etc.) can be sent to ANY application using these API calls, whether the application has the focus or not. This is very flexible and the window doesn't need to have the focus for this to work. If you use SendMessage then your VB program should wait for the target application to process the messages before continuing. With PostMessage, your VB program will post the messages and then continue immediately.
In summary, for my needs I ended up using PostMessage which worked great. I suggest trying the above options in order (i.e. easiest first) to see which works for you. Haven't got time to post code examples, but do a search on this forum or on google for any of the above and you'll have no problem finding code.
To answer your question about finding the previously active application, I don't think you need to if you use SendMessage/PostMessage and these will send to any Window you like, whether it has the focus or not. If you really need to then I believe there must be some API's to do with the zOrder of Applications (i.e. the order they appear when you press ALT+TAB). Anyone got any ideas?
Oh, one more thing... if you need to find and activate a window, try the following API's :
FindWindow
SetForegroundWindow
Hope this helps .
I believe this is what I am looking for?
-
Sorry for the double post (lol I need to leave this topic >_>;).
So, PostMessage, I think that is what I am looking for and I tried to do something with notepad...
MODULE CODE
Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String _
) As Long
Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" ( _
ByVal hWndParent As Long, _
ByVal hWndChildAfter As Long, _
ByVal lpszClassName As String, _
ByVal lpszWindowName As String _
) As Long
Declare Function PostMessage Lib "user32" _
Alias "PostMessageA" _
(ByVal hwnd As Long, _
ByVal wMsg As Long, _
ByVal wParam As Long, _
lParam As Long) As Long
Declare Function SetForegroundWindow Lib "user32.dll" (ByVal hwnd As Long) As Long
FORM CODE
Private Sub Form_Load()
' Find Notepad's handle
Dim hWndNotepad As Long
hWndNotepad = FindWindow("Notepad", vbNullString)
' Find the handle of the textbox, within the Notepad window
Dim hWndTextbox As Long
hWndTextbox = FindWindowEx(hWndNotepad, 0&, "Edit", vbNullString)
Call PostMessage(hWndTextbox, 3535, 0&, 0&)
Dim retval As Long
retval = SetForegroundWindow(hWndNotepad)
End Sub
Now What I am trying to accomplish here is setting whatever is in Notepad to "3535"...
I am getting the correct handle of the notepad window. I am just messing around, I am wondering if I am using PostMessage correctly?
Also, am I supposed to use PostMessage?

I'm really not sure why your setting the text in this obtuse way, why not just open notepad with the command line of a text document to open?
Anyhow, heres some C# code to do it. Shouldn't be hard to convert.

if (hWndTextbox != IntPtr.Zero)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder("My awesome text goes here.");
SendMessage(hWndTextbox, WM_SETTEXT, IntPtr.Zero, sb);
}
}
}
}
}

That line is my only problem....
EDIT:
Setting the text of Notepad is just a beginner thing till I set the text in a Server tool...
-
Just pass a string to the SendMessage function rather than a StringBuilder class. StringBuilder and similar classes are just C#'s way of abstracting the interop data casting.
EDIT: Word of warning, of your server tool has any passwords boxs you wish to set or get; It won't work. Windows protects them, they can only be accessed by their creator processes.

Second parameter of SendMessage needs to be WM_SETTEXT
-
Second parameter of SendMessage needs to be WM_SETTEXT
Ok, now WM_SETTEXT needs to equal 0xC correct? How do I define that then? what data type ... When I define it like an integer (in your c# example) VB throws an error specifically because of the "x" in 0xC
-
0x is the prefix used in C languages for declaring a numeric literal as hexidecimal. I believe in VB you use &H instead.
-
OK!, I finally got it work, but there is a simple problem (at least I hope so)
sb = "lol"
In notepad, it outputted "¬»"
-
Sounds like its not getting the data correctly. Probably have to pass a pointer, or a block of memory rather than a string (not sure how VB deals with casting between native and inbuilt data types).

Alternatively you can just put a if ! statement with all of the Keys used in your program. This is a very bad solution though...

If I have a multiline message, how do I only read the last line?
Maybe do a search for a "new line" character?...

The class names and window names are NOT the same thing that you would see in a .NET designer, don't assume they are. Use Spy++ or something similar to find out what they are.
If I have a multiline message, how do I only read the last line?
Maybe do a search for a "new line" character?...
I believe the .NET string class has a method called .split which you can use to split a message up into lines, just take the last in the splitted array.

Now, this is inefficient. What this is supposed to do is get the text from program B, process it, and set the text of the other program B to null. I set it to null so I can process one line at a time. There are a lot of sleeps, the main reason is because when I send a message then post the enter key, it doesn't work half of the time, so I make sure by sleeping for a bit...
Please tell me if there is a more efficient way.

Does anyone know how to create huds in C#/XNA? I know how to draw the images but not so code them, I'm sure I can code a number based hud system. Can't code a heart engine or a meter based hud yet.
-
In the world of C#, it depends on how you've set up your system, and how much you know and can learn. I could whip up a quick, general mini-tutorial for you, if you are interested.
I warn you, though, when I write tutorials, I explain things and expect you to learn what I'm teaching you to do, rather than you just taking the system and throwing it in without learning any of it. I want you to understand why I do things the way I do.
-
It's not that I don't understand, I just dunno how, I'd appreciate it if you did though^^
-
About half-way done (I started on it earlier). I'll finish it and upload it after I'm done playing TFU
-
Awesome thanks, this will be a huge help, I'll learn soo much from it^^

Say I have a ListBox in one program, and I want to get the List from that, convert it to a string, and put it in a text box in my program.
I have tried to get the ListBox's List:
hWndPlayers = FindWindowEx(hWndServer, 0&, "WindowsForms10.LISTBOX.app.0.378734a", vbNullString)
Yes this is VB
But, hWndPlayers returns 0... The class name is correct (I used WinSpy ++ 1.7). What could be going on?

A part of me really hopes this is a troll... Say you want to learn a language. Not a programming language, a real one. Like French or German or Japanese. You start off with the basics, learn how to introduce yourself, how the words fit together. Then you start to form basic sentances, and so-on.
Learning a programming language is very similar. You learn the basics, what commands do and mean what, how the syntax is organised (if it's not drag & drop) and so-on. You read about the basics, and use them to form sentances, or small programs as is the case. Then you use this acquired knowledge to learn and understand more, until you know enough to effectively communicate in the language, or in the case of programming/dragging-and-dropping-pansy-game-maker-work effectively get a developed and function program up and running.
TL:DR version: Read the tutorials, learn the basics and apply them.
-
You should start by downloading some Game Maker examples and study them, here are a bunch you can download (http://www.kousougames.com/examples.php). You could read the help file of Game Maker too, it really helps when you don't know how this or that function works. Game Maker has got an official forum too, there you can get help and you can find lots of tutorials. And finally I think you can ask for help on this forum, I know there are a bunch of people who use Game Maker here.

I seem to be having an odd C++ linker error. It's probably something simple...
I have a singleton template class. Now, obviously this contains a static templated pointer. This needs to be declared, so I do this in a special cpp file, ISingleton.hpp.
Now, if I do a full-on templated declaration of:
template <class T> T* DOM::System::Tools::ISingleton<T>::_pv_singleton = 0;
I get compile-time errors of undefined references to _pv_singleton. Now, if I do this in main.cpp instead of ISingleton.cpp, it compiles and executes without complaint. Similarily, if I specialise the class in ISingleton.cpp, say:
template <> int* DOM::System::Tools::ISingleton<int>::_pv_singleton = 0;
and then create a singleton of type ISingleton<int>, this also compiles fine.
Anybody got any idea why this is screwing with me like this? :)

Try making it static? What does the error read?

make what static? The pointer in the class is static <_<
Error is just

Turns out the problem is with how C++ compilers link together CPP files. They remaie aware of template specialisation but not of the more abstract version. I created a define macro which allows for specialisation easily in CPP files and left it at that, seems like a good approach in the end when I think of it, since I create templates with the likelyhood of them being specialised for certain uses in mind (policy based design has me by the balls).

- Removed. I'm dumb.

What is wrong with this?
//Everything is good, update the database
$query = "UPDATE news SET title = ".$newstitle.", post = ".$newspost.", date = ".$date." WHERE id = ".$id." LIMIT 1 ";
$result = $connector->query($query);
if ($result==1)
{
header("location:index.php");
}
else
{
$error = "Error, could not insert into database!".$result.$id."";
header("location: index.php?action=error&message=".$error."");
}
I always get the error message "Error, could not insert into database!"...
I have triple checked the query and the actual table.
-
Not sure off hand. I usually use mysql manually, I don't use proxy objects.
However the things I would recommend checking is both that the result returns 1 on true (usually its 0 if successfull). And I would also quote all the strings in your query, as well as escape any quotation marks within the values to prevent sql injection.
eg.
$query = "UPDATE news SET title = '".addslashes($newstitle)."', post = '".addslashes($newspost)."', date = ".$date." WHERE id = ".$id." LIMIT 1 ";

$result is returning nothing for some reason.
$error = "Error, could not insert into database!".$result.$id."";
For example, would display as "Error, could not insert into database!20"; 20 is the id, so the result = ""...
-
Assuming that $connector is a PDO object... Try this instead:
//Everything is good, update the database
$query = "UPDATE news SET title = ".$newstitle.", post = ".$newspost.", date = ".$date." WHERE id = ".$id." LIMIT 1 ";
$result = $connector->exec($query);
if ($result==1)
{
header("location:index.php");
}
else
{
$error = "Error, could not insert into database!".$result.$id."";
header("location: index.php?action=error&message=".$error."");
}
-
No no, I figured it out. Apparently it wanted single quotes around the values and no quotes around the field names : /
Btw, Connector is a class (lol my first ever php class).

Sorry for double posting, but it seems like no one else is using this topic :P
Is there any motion path system in Blitzmax? Anyone know how I can implement it?
-
No there isn't a built in one. Its something that would normally built on a the higher-level game engine, its not something that would be built into a language. Its not exactly hard to do though, try writing your own.

Do you know of any ones already made? I am using this for the competition and I don't exactly have the time.
-
No. As I said, the system is not exactly hard to build, nor that time consuming. I doubt anyone has made a module specifically for it.

Regarding hitboxes in C++, what would be the fastest way to check if the player is colliding with one of them? Say, there's 20 hitboxes, basically how could I quickly check if the player is colliding with one of them? The hitboxes are instances of a class called CHitBox and a collision is detected through a function that returns true or false based on where the two hitboxes being checked are located in relation to one another.

There are all kinds of intresting ways to deal with collision detection, it really depends on the effort you want to put in and how badly you want to optimize it. You could do the simple route of just iterating through all objects and testing the players hitbox against the objects hitbox, and returning a collision if any exist. Or if you want you could build up a quadtree or a similar data structure and limit all collision detection to hit boxes within the leaf of the tree that the player is in. Its really up to you. For the majority of the time though, simply interating through a list will be more than fine, especially when you only have 10 or so.
-
Well, 10 was only an example, I expect to have a lot more than that. But, considering how my collision algorithm works, I don't think it will take too much time to iterate through a list. Thanks, I'll see what I can do.

Is there something I should know about the SendMessage API function and VB 2005? It doesn't want to work for me at all :|
Declaration:
Declare Function SendMessage Lib "USER32" Alias "SendMessageA" ( _
ByVal hWnd As Long, ByVal Msg As Long, _
ByVal wParam As Integer, ByVal lParam As String) As Long
Usage:
Call SendMessage(hWndTextbox, WM_SETTEXT, 0, "--- XMX MOD ---")
The odd thing is that the code worked perfectly in VB 6 :|

What's the error that you're getting? I don't think you need that call command in there..

How can I read the data from a comma delimited file with C++? I've got a VB program that outputs data like this to a file, for example:
-1, -1, 0, 5, 6, 4, 3, 3, 3, 3, 3 , 1, 25, 30, 99, 80, 5, "Player", 10, 12
(just made some numbers up..)
How could I read these into a C++ program? I'm not really too familiar with file I/O in this language.
-
well you could go through it byte by byte appending to a string as you go until you hit the end of file or a comma,
then convert the string to an integer value...
