How can I create a Window

[CyberCarsten]

How can I create a Window in a Win32 App using Borland C++??? (Doesn't have to be complex or anything... )

[Vlatko]

This will create a window:

#include <windows.h>
LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM);
char szWinNamw[] = "MyWin";
int WINAPI WinMain(HINSTANCE hThisInst, HINSTANCE hPrevInst,
				LPSTR kposzArgs, int nWinMode)


    {
    	HWND hwnd;
    	MSG msg;
    	WNDCLASSEX wcl;
    	wcl.cbSize = sizeof(WNDCLASSEX);
    	wcl.hInstance = hThisInst;
    	wcl.lpszClassName = "My Window";
    	wcl.lpfnWndProc = WindowFunc;
    	wcl.style = 0;
    	wcl.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    	wcl.hIconSm = LoadIcon(NULL, IDI_WINLOGO);
    	wcl.hCursor = LoadCursor(NULL, IDC_ARROW);
    	wcl.lpszMenuName = NULL;
    	wcl.cbClsExtra = 0;
    	wcl.cbWndExtra = 0;
    	wcl.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
    	if(!RegisterClassEx(&wcl)) return 0;
    	hwnd = CreateWindow(
    		"My Window",
    		"Skeleton Window",
    		WS_OVERLAPPEDWINDOW,
    		CW_USEDEFAULT,
    		CW_USEDEFAULT,
    		CW_USEDEFAULT,
    		CW_USEDEFAULT,
    		HWND_DESKTOP,
    		NULL,
    		hThisInst,
    		NULL
    		);
    	ShowWindow(hwnd, nWinMode);
    	UpdateWindow(hwnd);
    	while(GetMessage(&msg, NULL, 0, 0))


        	{
        		TranslateMessage(&msg);
        		DispatchMessage(&msg);
        	}
        	return msg.wParam;
    }
    LRESULT CALLBACK WindowFunc(HWND hwnd, UINT message,
    							WPARAM wParam, LPARAM lParam)


        {


            	switch(message)	{
            	case WM_DESTROY:
            		PostQuitMessage(0);
            		break;
            	default:
            		return DefWindowProc(hwnd, message, wParam, lParam);
            	}
            	return 0;
        }

I get the following errors:

Line 11:Undefined symbol 'WNDCLASSEX' in function __stdcall WinMain(void*,void*,char^,int)

Line 11: Statement missing ; in function __stdcall WinMain(void*,void*,char^,int)

Line 12: Undefined symbol 'wcl' in function __stdcall WinMain(void*,void*,char^,int)

It works fine in VC++ as for Borland C++ i never used it. But it is the same language the same API's. There must be some little catch in Borland.

[CyberCarsten]

Do you have a clue on what it might be???
Do you know where i can get VC++ (for free )

you're using borland turbo C++ 4.5, am I correct?

the default are borland EZWin

go to

Project -> New Project
and if it's not already selected, click "application(.exe)"

set your preferences, etc. click Ok...

No, I'm using Borland C++ 4.5.
But I discovered that the BC 4.5 compiler couldn't hande the Win32 API properly, so I downloaded the BC 5.5 compiler from borland's website, and it works fine now!
Thanks for all your help guys!
