Re: Scanning pdf file to SQL Server
Ok I think that I figured out how to save it properly in the table. Now how do I display it as a pdf file on a form?

Re: Scanning pdf file to SQL Server
I don't mean the code to save the file in the table but the part where I acquire the image from the scanner and convert it to the type to save to an image field in the table.

Re: Problems with scanning and distortion
Well I switched and used the WIA driver instead of the twain and that seemed to solve the problem.

Problems with scanning and distortion
When scanning a document by manually pressing scanner buttons, document scans perfectly. When using the library, and programmatically scanning the document, the document appears distorted. This is on an hp N6010 scanjet.

Re: HP scanners.
I am testing the library with an HP Scanjet N6010 and so far it works just fine. I was getting a stackoverflow exception at first, but after setting
