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?...

Peter.
---------------------------------------------------------

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

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

int _tmain(void)
{
DialogBoxParam(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_DIALOG1),
NULL, (DLGPROC)MainDialogProc, 0);
return 0;
}
-------------------------------------------------------------
This is the resource.h file:
-------------------------------------------------------------
//{{NO_DEPENDENCIES}}
// Microsoft Developer Studio generated include file.
// Used by Step1.rc
//
#define IDD_DIALOG1                     101

// Next default values for new objects
//
#ifdef APSTUDIO_INVOKED
#ifndef APSTUDIO_READONLY_SYMBOLS
#define _APS_NEXT_RESOURCE_VALUE        102
#define _APS_NEXT_COMMAND_VALUE         40001
#define _APS_NEXT_CONTROL_VALUE         1000
#define _APS_NEXT_SYMED_VALUE           101
#endif
#endif

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);

What's your .def file?

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;
}

Peter.

You'll need a file called "program.def" in it, and it should contain the
line:
    EXETYPE WINDOWS

How are you compiling in the resource?
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);

}
