Jos,

You can get a snapshot of a form using the GDIPlusX library, but it includes the title and border. (I can make a change to the library so you get just the client area of the form if it this helps.)

It is pretty straight forward:

DO System.APP
WITH _Screen.System.Drawing
  ** Get Bitmap object from a VFP form
  oImg = .Bitmap.FromScreen( oMyForm )

  ** Save to file:
  oImg.Save("MyForm.jpg", .Imaging.ImageFormat.Jpeg)

  ** Save to variable:
  oStream = =_Screen.System.IO.MemoryStream.New()
  oImg.Save(oStream, .Imaging.ImageFormat.Jpeg)
  cMyForm = oStream.GetBuffer()

ENDWITH
