If it really is a handle to a GDI+ bitmap, then look at Image.FromHBitmap(handle as IntPtr). -- Mike

Can anybody help? Did you already take a look at the overloaded 'Bitmap' constructor? There is one overload ('New(Int32, Int32, Int32, PixelFormat, IntPtr)') which expects a pointer to binary bitmap data in its last parameter. -- M S Herfried K.
