WzdBtmap.cpp -- a bitmap class which reads a file and creates a bitmap
WzdBtmap.h

/////////////////////////////////////////////////////////////////////
// Modify any class with a window.
/////////////////////////////////////////////////////////////////////

// 1) embed the bitmap in the class
	CWzdBitmap m_bitmap;

// 2) load bitmap, typically when processing the window's WM_CREATE message
	m_bitmap.LoadBitmapEx(IDB_WZD,TRUE);

// 3) draw bitmap
	// get bitmap colors
	CPalette *pOldPal = pDC->SelectPalette(m_bitmap.GetPalette(),FALSE);
	pDC->RealizePalette();

	// get device context to select bitmap into
	CDC dcComp;
	dcComp.CreateCompatibleDC(pDC);
	dcComp.SelectObject(&m_bitmap);

	// draw bitmap
	pDC->BitBlt(0,0,m_bitmap.m_Width,m_bitmap.m_Height, &dcComp, 0,0,SRCCOPY);

	// reselect old palette
	pDC->SelectPalette(pOldPal,FALSE);
