pcsoft.us.windevCopyright 2026, PC SOFT6 May 2020 21:25:56 Z21 Apr 2015 23:21:00 ZMy colleague is working on some a sample project and is unable to use TwainSelectSource() or use any Twain functions. He gets this error, "Unable to open SourceManager(TWAINdsm.dll)." The weird thing is it works just fine with the same exact code if he pulls up the WD Scanning example. We've tried creating new projects in different directories. We've tried creating a new project in the same directory as the examples. I had him delete his cpl folder and project.env file. We've restarted the printer and the computer. Nothing works, except for WD Scanning example. I used the same printer/scanner and the same code recently without problems.
