GdPicture.NET 8 - Can't Find Scanner in Release Mode Only

[jrowlen]

I am working with GdPicture.NET 8 with Any CPU configuration.
Everything works fine in debug mode. However, in release mode, the GdPictureImaging fuction TwainGetSourceCount(IntPrt handle) always returns a value of 0.

Do you know why this is happening?

BTW, the OS is Windows 7, 64 bit.

Hi,

All is OK for me. Ensure yourself that you have a valid 64 bit TWAIN driver on your OS. Else, you will have to target your app to x86 in order to use the 32-bit TWAIN driver version.

Kind regards,
