Dialog Problems

[CV3]

I'm trying to create a program with a dialog as the main window but it doesn't display. What am I doing wrong? (Using Dev-cpp)

Dialog Resource:

IDD_MAIN DIALOG 146, 39, 260, 265
STYLE WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU
CAPTION "Dialog Title"
FONT 8, "MS Sans Serif"
BEGIN
    LISTBOX         301, 12, 47, 120, 192, LBS_SORT | WS_VSCROLL | WS_TABSTOP
    LTEXT           "View", 302, 12, 17, 20, 12
    COMBOBOX        303, 13, 26, 120, 83, CBS_DROPDOWN | CBS_SORT | WS_VSCROLL | WS_TABSTOP
    IDB_ADDENTRY PUSHBUTTON      "Add Entry", 304, 14, 239, 55, 14
    IDB_DELETEENTRY PUSHBUTTON      "Delete Entry", 305, 75, 239, 55, 14
    GROUPBOX        "Entries", 306, 6, 6, 132, 254
END

Main File:

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

BOOL CALLBACK MainDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
	switch(Message)
	{
		case WM_INITDIALOG:
		    ;
		break;
		case WM_CLOSE:
			EndDialog(hwnd, 0);
		break;
		case WM_COMMAND:
		
		break;
		case WM_DESTROY:
			
		break;
		default:
		    	
			return FALSE;
	}
	return TRUE;
}

int WINAPI WinMain (HINSTANCE hInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR lpszCmdLine,
                    int nCmdShow)

{
    return DialogBox(GetModuleHandle(NULL), 
                MAKEINTRESOURCE(IDD_MAIN), hwnd, MainDlgProc);
}

Thanks for any help...

So far i have not see your resource.h but be resource contains an ID number. And your RC file doesnt has " #include "resource.h" " line.

You dont need GetModuleHandle(NULL) since you have "HINSTANCE hInstance" in main. Use "hInstance" there.

And most important:

int DialogBox(

HINSTANCE hInstance, // handle to application instance
LPCTSTR lpTemplate, // identifies dialog box template
HWND hWndParent, // handle to owner window
DLGPROC lpDialogFunc // pointer to dialog box procedure
);

yours:

hwnd, MainDlgProc

hwnd: completely wrong use "0". A dialog never be a parent of itself Maybe desktop.

MainDlgProc: for this, try to adding (DLGPROC) casting.

return DialogBox(hInstance, 
                MAKEINTRESOURCE(IDD_MAIN), 0, (DLGPROC) MainDlgProc);

I'm not an expert at windows but dont you have an extra ) after IDD_MAIN in MAKEINTRESOURCE?

Linuxman - I don't see that

fizisyen - thanks for your reply. That isn't the whole of my .rc file just the part with the dialog code The dialog is defined properly in resource.h as well.

I tried eveything you suggested but the program just exits without displaying the dialog at all.

these lines are wrong,

    IDB_ADDENTRY PUSHBUTTON      "Add Entry", 304, 14, 239, 55, 14
    IDB_DELETEENTRY PUSHBUTTON      "Delete Entry", 305, 75, 239, 55, 14

must,

    PUSHBUTTON      "Add Entry",IDB_ADDENTRY, 304, 14, 239, 55, 14
    PUSHBUTTON      "Delete Entry",IDB_DELETEENTRY , 305, 75, 239, 55, 14

and one more mingw specific "WARNING": always be sure your resource files names(.rc) diffrent from some other implementation file(.c .cpp) . Because, every compiled file has the same extension ".o" so, not important what is the extension(.cpp or .rc) this will do by DevC++ automatically by adding "_res.h". But please use project templates. There are every possible needs for you.

And i compiled successfully your source. Anyway, this is Relo project(freeware ide like Dev)
