Thread: Dialog Bg

Hi
I am trying to set a bitmap background for my dialog box. The compilation runs without any errors but the background does not appear at all.

Dont you know what might be wrong?

Code:

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

HBRUSH		hBG;
HINSTANCE	hInstance;
HDC		hDC;

INT_PTR CALLBACK DialogProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	switch ( uMsg )
	{
		case WM_COMMAND:
			switch ( LOWORD(wParam) )
			{
			case IDCANCEL:
				DeleteObject(hBG);
				EndDialog(hwndDlg, LOWORD(lParam));
			}
			break;
		case WM_CTLCOLORDLG:
			SetBkMode((HDC)wParam, TRANSPARENT);
			return (INT_PTR)hBG;
			break;
		case WM_INITDIALOG:
			hBG = CreatePatternBrush(LoadBitmap(hInstance, MAKEINTRESOURCE(IDB_bg)));
			break;
	}
	return FALSE;
}


int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInst,
	LPSTR lpCmdLine, int nShow)
{
	return DialogBox(hInstance, MAKEINTRESOURCE(IDD_DIALOG_MAIN),
		NULL, (DLGPROC)DialogProc);
}

MSVC++

Thank you for any help
