Hi all,

Still Struggling!

I'm trying to produce a simple window. It compiles OK but nothing seems to
happen! Am I trying to achieve the impossible or am I doing  something totally
wrong?...

Hi Peter,

I think returing FALSE from the DLGPROC might be the problem. The DLGPROC
handles all messages, which include things such as creation and
initialisation of the dialog. Returning FALSE would indicate failure and
terminate your processing prematurely. Try to find a default function to
call, replacing return FALSE with something like:

return DefWindowProc (hWnd, uMsg, wParam, lParam);

Walter,

Sorry for my ignorange but could you explain what .def file is needed?
When the cd arrives I'll probably have some reading to do!.

Anton,

I've tried many variations but with no luck. In fact I haven't yet managed to
get a non-console program to work!. Below is the most minimal program that if I
understand correctly should work without invoking the console but it does. I
think I must be making some mistake while compiling...

#include <windows.h> 

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int) 
{
MessageBox(NULL, "Hello world!", "Sample", MB_OK);
return 0; 
}

Show us the .rc file too.
Is the .res file getting generated correctly and is it linked into your
executable?

Check if the return value of DialogBoxParam is -1 and if so, try to output
the error message from Windows.

if (DialogBoxParam(....) == -1) {

LPTSTR lpMsgBuf;

FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER |

FORMAT_MESSAGE_FROM_SYSTEM |

FORMAT_MESSAGE_IGNORE_INSERTS, NULL,

GetLastError(), MAKELANGID(LANG_NEUTRAL,

SUBLANG_DEFAULT),

(LPTSTR) & lpMsgBuf, 0, NULL);

MessageBox(NULL, (LPCTSTR) lpMsgBuf, TEXT("Error"),

MB_OK | MB_ICONSTOP);

LocalFree(lpMsgBuf);

}
