I use this code to load a TPicture in an TImageEnView:

ImageEnView1.IEBitmap.CopyFromTBitmap(APicture.Bitmap);
ImageEnView1.Update;


Isn't there a way to DIRECTLY load a TPicture in TImageEnView? (Without the detour over TPicture.Bitmap).

The reason is: My particular TPicture is a perfectly valid TPicture and can be used successfully as TPicture. But as soon as I try to access its BITMAP property I get an Access Violation! (Doesn't a TPicture automatically contain a Bitmap?)

Hi Peter

Some formats, such as meta files do not contain bitmaps. You should be able to assign the graphic as follows:

ImageEnView1.IEBitmap.Assign( APicture.Graphic );
ImageEnView1.Update();

Also, for 9.1.2 you can assign a TPicture to a TIEBitmap or TImageEnView
