calling GetThumbnailImage()

How do I use GetThumbnailImage()? What do I do with the Abort CallBack delegate? I am currently using null which seems to work, but is probably not a good idea.

It is used so that you can pass a reference to a method that will be called periodically to determine if the Thumbnail generation should be cancelled.

The help says that it is not currently used at the moment, so passing a null reference should be fine.

The german .net class library documenation says that you must create a GetThumbnailImageAbort delegate. But the GDI+ 1.0 documentation says that this delegate is optional (for native languages).
So I think you should better create a delegate which just returns false
