C++, Ahhh This Anoying...

Ok, alot of the times I try out my program, I get errors, when I know theres NOTHING wrong. I even tryed one of there premade things, and its wrong =O. Here, whats wrong with this code?:

#include <windows.h>

static char g_szClassName[] = "MyWindowClass";
static HINSTANCE g_hInst = NULL;

#define IDC_MAIN_TEXT 1001

{

if(SetWindowText(hEdit, pszFileText))
bSuccess = TRUE; // It worked!
}
GlobalFree(pszFileText);
}
}

}
return bSuccess;

Whats wrong with that? Please help :)

Could you at least tell us where your compiler is telling you there's a mistake?

[blah569]

OK, here is the mistake:

case CM_FILE_OPEN:

What is wrong with that?

[PONGpaddle]

http://search.micros..&qu=CM_FILE_OPEN

Unless it's undocumented, it doesn't look like CM_FILE_OPEN exists.

[thoughtpolice]

Oi. It's fairly obvious you know nothing about the code you're using or even understand ANY of it. Otherwise you should have been able to figure this out fairly easily.

It's pretty obvious that the CM_* family of Window messages are part of a menu that is contained somewhere in a resource file. You don't have the resource file, you don't have the header file to accompany it, and therefore all your user-defined Window messages aren't defined. This requires a menu and a resource file which you don't have.

I suggest you stay away from Windows programming for a while, since you obviously don't know anything about it and you're probably just learning it because console shit feels boring.

That's probably the biggest egotistical load of shit I've ever heard in my life. The general rule of thumb is this:

It's your fault. Not the compilers.

I'm not even gonna comment, just look at his html posts

looks the other way

[Jcrypt]

Yes as said before... CM_FILE_OPEN isn't even defined.. you obviously copy/pasted from someones source somewhere and 2nd that's not even really C++ persay I mean yes it's scripted in it but it's Win32 ( not a big diff but i'm a techinical whore ) So go look up Win32 Programming and please never post someone elses code claiming it again.. k?

(Key.isDown(Key.UP)) { _y -= 10; _rotation = 270; }}onClipEvent (enterFrame) { if (Key.isDown(Key.DOWN)) { _y -= -10; _rotation = 90; }}onClipEvent (enterFrame) { if (Key.isDown(Key.LEFT)) { _x -= 10; _rotation = 180; }}onClipEvent (enterFrame) { if (Key.isDown(Key.RIGHT)) { _x -= -10; _rotation = 0; }}

something is wrong can u help me plz?

Oh for fuck sake, their multiplying. Wrong forum mate. Dont ask why just get yourself into the flash forum.

[Craige]

lol, and why did he post that in a C++ topic?

You would be doing the world an excellent favor by killing yourself. Please do so, or at least never ever post unless you know what you are talking about. This is C++, it is using the WINAPI. It is the same language, using a differant library than the standard IOSTREAM library which runs in a CMD or DOS window. No the IOSTREAM Library is NOT the entire C++ language.

wow... how bout you shut the fuck up? IF you could read... I clearly said "It's not C++ persay" in other words it is but isn't... As you said yourself it's using the WINAPI so stfu and go sit worthless fuckin idiot..

Seeing how the general consensus is that you don't know much about this topic -- i.e. Win32 -- (seeing how your posts have basically summed up to ("don't try this until later" and "shut the fuck up"), plus the fact you haven't proven you're extremely smart judging on the ad hominem in your post and your grammar, I'd say that it'd be damn near impossible not to pick at you.

The WINAPI through assembly, C++, Delphi, J++? You honestly don't know what you are talking about, so please shut your trap.
