That appears to be the issue. I removed the viewer control and it seemed to work fine. Thanks!

Just starting to use the TWAIN controls and we have purchased a license. I have added the license to the code (GdViewer1.SetLicenseNumber = XXXX). But the word "DEMO" stays on the background. How do I remove that? Thanks P.S. How do you send PMs? I swear it must be obvious, but I couldn't ...

Thanks - that worked great!

Attempting to evaluate the twain_sample (in .Net) and when clicking on the create image and save to PDF, the program crashes. I can scan to JPG, but not to PDF. Any ideas? I have upgraded the sample to VS 2008.
