Resources

I just started Win32 API with my Borland C++ compiler. I just want to load a dialog box... I don't want to include any function to the buttons what so ever. I just want to see the dialog box... I tried to compile the code from sunlights windows tutorial and it doesn't bring up the dialog box... heres the code:

Code:

#include <windows.h>
#include <tchar.h>
#include "char.h"

BOOL MainDialogProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	return FALSE;
}

int _tmain(void)
{
	DialogBoxParam(GetModuleHandle(NULL), MAKEINTRESOURCE(DIALOG2), 
		NULL, (DLGPROC)MainDialogProc, 0);
	return 0;
}

You forgot to include your resource.h file!

char.h is my resource file

sunlight's using resource.h...is char.h the exact same thing? if not, the problem might lie in char.h

Try using DialogBox( ) function instead of DialogBoxParam( )..
DialogBoxParam is for Windows CE. DialogBox is the Win32 equivalent. If that does not work, try handling the WM_INITDIALOG case in your message proc, and using ShowWindow( ). I think it should work without that though.

DialogBoxParam is fine...and can be used as you wish

In fact if out look at your include's the real truth might show that DialogBox is an imposter and uses DialogBoxParam to do the work

Code:

#define DialogBoxA(hInstance, lpTemplate, hWndParent, lpDialogFunc) \
DialogBoxParamA(hInstance, lpTemplate, hWndParent, lpDialogFunc, 0L)
#define DialogBoxW(hInstance, lpTemplate, hWndParent, lpDialogFunc) \
DialogBoxParamW(hInstance, lpTemplate, hWndParent, lpDialogFunc, 0L)
#ifdef UNICODE
#define DialogBox  DialogBoxW
#else
#define DialogBox  DialogBoxA
#endif // !UNICODE

</secret>

The code worked ok for me.....most probable that you havent included the resource in the project, or you are using the wrong ID (could DIALOG2 be DIALOG1???)

Also....add this to your dialog proc

Code:

switch(uMsg){
	case WM_CLOSE:
		EndDialog(hWnd,0);
		return TRUE;
	}

Cuz when you get that dialog working finally, you may find you cant get rid of it without the above code

I don't get any errors... the window just doesn't come up.

Are you linking your resource.rc file to the project?

yes
