The code shown below was copied from a previous post & it works fine for
"image files". I would like to make this work like "Windows file
Explorer" works when you change the view to "Thumbnail" but for CAD
(AutoCAD) files. While in explorer, I could see the thumbnail of my CAD
files. Can this be accomplished? I already know about the
"dwgthumbnail.ocx" thats all over the NET but it doesn't quite work for
me. Thanks in advance for your help.

If ofd.ShowDialog() = Windows.Forms.DialogResult.OK Then
Dim image As New Bitmap(ofd.FileName)
Dim pThumbnail As Image = image.GetThumbnailImage(PictureBox1.Width,
PictureBox1.Height, Nothing, _
New IntPtr())
PictureBox1.Image = pThumbnail
End If
End Sub
End Class
