Are you seriously develop .NET with MFC? I'm just curious; it looks crazy to me... How much of progress, I wonder?

I don't think it makes practical sense (I mean the whole idea: .NET + MFC), but in principle, you can. Here is how:

Yeah,I Know this function
I write some codes

1 public static Bitmap GetPrevBitmap()
2 {
3 IntPtr hBitmap = GetPreBitmap();
4 return Bitmap.FromHbitmap(hBitmap);
5 }
but in line 4 throw a exception: A generic error occurred in GDI+.

This method does work.
Are you sure this is a valid bitmap handle? I don't know what is your GetPreBitmap().
