Trying to display a bitmap in a dialog.

[AxessTerminated]

I can't get a bitmap to display in a dialog. I have a DLL that someone else wrote. It's called cards.dll (not the windows one). I also have a header he included, renamed to "defines.h", which defines names for all the cards in the DLL.

I loaded the DLL in the OnInitDialog() function, but do not understand how to use BitBlt, so I set the HDC crap to NULL for now, hoping someone can both explain this to me, and help me display the bitmap. Also, if there is a better way to go about doing this, explain please, and include source. Keep in mind I do not know VC++ very well, and am learning through trial and error.

My goal is to create a card simulator. It will display cards, and you can move them, flip them, etc...but there are no rules. This way, you can play any game you want. I have a few quirks to work out in the logic, but I need to get the basics of the code down first.

BOOL CCardsDlg::OnInitDialog()
{
	CDialog::OnInitDialog();

	HMODULE hModule = LoadLibrary("Cards.dll"); 

	//LOAD THE BITMAP
	HBITMAP hBitmpap = 
    LoadBitmap(hModule,MAKEINTRESOURCE(IDB_H01)); 
	//IDB_H01 IS THE ACE OF HEARTS, WHICH CORRESPONDS TO 4001


    BitBlt(NULL,0,0,10,10,NULL,0,0,SRCAND);


	// Add "About..." menu item to system menu.

	// IDM_ABOUTBOX must be in the system command range.
	ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
	ASSERT(IDM_ABOUTBOX < 0xF000);

	CMenu* pSysMenu = GetSystemMenu(FALSE);
	if (pSysMenu != NULL)
	{
		CString strAboutMenu;
		strAboutMenu.LoadString(IDS_ABOUTBOX);
		if (!strAboutMenu.IsEmpty())
		{
			pSysMenu->AppendMenu(MF_SEPARATOR);
			pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
		}


	}

	// Set the icon for this dialog.  The framework does this automatically
	//  when the application's main window is not a dialog
	SetIcon(m_hIcon, TRUE);			// Set big icon
	SetIcon(m_hIcon, FALSE);		// Set small icon
	
	// TODO: Add extra initialization here
	
	return TRUE;  // return TRUE  unless you set the focus to a control
}

Instead of NULL, try using hBitmpap. And use the handle of another bitmap for the second bitmap.

The BitBlt function performs a bit-block transfer of the color data corresponding to a rectangle of pixels from the specified source device context into a destination device context.

BOOL BitBlt(
HDC hdcDest, // handle to destination DC
int nXDest, // x-coord of destination upper-left corner
int nYDest, // y-coord of destination upper-left corner
int nWidth, // width of destination rectangle
int nHeight, // height of destination rectangle
HDC hdcSrc, // handle to source DC
int nXSrc, // x-coordinate of source upper-left corner
int nYSrc, // y-coordinate of source upper-left corner
DWORD dwRop // raster operation code
);
