Help with windows programming

Appearently my compiler does not like that I don't have a _main in my program, and isnt seeing the winmain() as the main. Ive never tried anything like this in borland before. Whats borlands problem? Here is the error:

Borland C++ 5.5.1 for Win32 Copyright (c) 1993, 2000 Borland
C:\test.cpp:

and here is the code:

CPP / C++ / C Code:

#include <iostream>
using namespace std;

#include <windows>

#include <cstring>


int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hPrevInstance,
                   LPSTR lpCmdLine, int nCmdShow)
{

	typedef struct _WNDCLASSEX {
	    UINT    cbSize;
	    UINT    style;
	    WNDPROC lpfnWndProc;
	    int     cbClsExtra;
	    int     cbWndExtra;
	    HANDLE  hInstance;
	    HICON   hIcon;
	    HCURSOR hCursor;
	    HBRUSH  hbrBackground;
	    LPCTSTR lpszMenuName;
	    LPCTSTR lpszClassName;
	    HICON   hIconSm;
	} WNDCLASSEX;

WNDCLASSEX sampleClass;

sampleClass.cbSize =        sizeof(WNDCLASSEX);
sampleClass.style =         CS_DBLCLKS | CS_OWNDC |
                            CS_HREDRAW | CS_VREDRAW;

sampleClass.cbClsExtra =    0;
sampleClass.cbWndExtra =    0;
sampleClass.hInstance =     hinstance;
sampleClass.hIcon =         LoadIcon(NULL, IDI_WINLOGO);
sampleClass.hCursor =       LoadCursor(NULL, IDC_ARROW);
sampleClass.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH);
sampleClass.lpszMenuName =  NULL;
sampleClass.lpszClassName = "Sample Class";
sampleClass.hIconSm =       LoadIcon(NULL, IDI_WINLOGO);

return(0);
}

Dang, nobody can help me here? Ive just spent 2 hours researching and www.borland.com's documentation and bulletin was not even the slightest help. In the documentation it said that I had to give a -w parameter to tell it which kind of application to build (it builds console by default, but we all know this i think). The compiler doesnt recognize this -w command that was given by the freakin borland developers themselves. So I type 'bcc32' help and I get something like -tWxxx(or something like that) to build a windows application. So I try that too. The compiler doesnt recognize that either. I really don't want to have to install visual studios. What a pain in my butt. All that microsoft stuff comes with way more overhead than I need. I like doing things manually anyway.

Give us time. We are volunteers with a life ouside of this board. If you want immediate help, you need to call us on the phone and let us know you're posting a question so we can drop what we're doing to answer it ;-)

-w is to set the compiler's warning level.

Mine does. Although I've never actually written a program using it

I'm with you there.

By the way, aaron's link won't help you with the compiler, if you haven't discovered that yet.

Try the info at this google search. OWL is Borland's version of MFC I believe, but doesn't come standard with 5.5. Or simply avoid the winmain() crap and use Windows API's to do your Windowing.

Here's a book that may help http://www.accu.org/bookreviews/publ.../m/m000786.htm
It's for ver 4.1 but most of the info is probably applicable to 5.5

Well, the compiler, no. I saw the code and noticed a few things were missing, so I gave a link to a good website. Although, I really didn't read the post that well, I don't know jack about the Borland compiler interface. As far as making a windows program with borland... I've never been able to do it with WinAPI. The only success I've ever had with that lies in the only other compiler I've used: MSVC 6.

WinMain() is WinAPI, isn't it? All windows programs need a WinMain() function, at least.

Well, I know there's an <iostream>... perhaps he has a <windows>?

LOL!. I laugh because of the 3 day discussion that question recently instigated. The .h extension was intentionally left out. C++ compilers no longer use the extensions. You can read about it here: http://www.gidforums.com/t-2407.html

machinated · #9 15-Apr-2004, 19:27

i dunno about that, but even so is ur compiler up to date?

These both refer to iostream.h and windows.h. The h is implicit. And this was covered to death in that other post
