Using GdPicture.NET 12 COM Edition in Microsoft Access

See examples [INSTALLATION FOLDER]\samples\AnyCPU\msaccess using com interop

Note:

• IntelliSense is fully supported.
• Trick for resizing GdPicture controls (thanks to Greg N.):
  Use the menu at the top to insert an activeX control. Pick the GdPicture.NET usercontrol. It will be a default size.
  Then use the lower right corner and drag the size of the control to what you want. Save the form, close, then double click to open it.
  Be sure you also set the anchoring on the control so windows does not try to resize it based on the form size. The control reacts badly to this. Set it to top left.
  Nothing fancy but works!
