Dear All,

I need your help on this, I am maintaining a VB 6.0 application for a developer, this application utilizes this ScanDLL50 (TWAIN compliant API).

I am debugging this application under a Windows XP SP 2 machine. The scanner I am using is a HP Scanjet 8350.

When every I do a scanning using my application, it will hang for 15 minutes and after that resume back to normal, and with an error code of 20.

I am having problems trying to find the API for this DLL file, if you have any experience programming this DLL could you please reply to me on this forum, thank you.
