Q.  How do I load a resource bitmap into a GDI+ bitmap?

A.  Use this function:

Bitmap *ResourceToBitmap(const HINSTANCE hInstance, const int id)
{
	HBITMAP hBmp = ::LoadBitmap(hInstance, MAKEINTRESOURCE(id));
	if (bBmp == NULL) return NULL;
	return Bitmap::FromHBITMAP(hBmp, NULL);
}

void ExampleUse()
{
	Bitmap		*pBitmap;

	pBitmap = ResourceToBitmap(AfxGetInstanceHandle(), IDB_MY_BITMAP);
	printf("Size is %d x %d\n", pBitmap->GetWidth(), pBitmap->GetHeight());
}
