I’m the customer/user Loic was referring to in his earlier post. I’ve downloaded the latest TWAINDSM, 126.96.36.199, and am still having problems.
I’m running under Windows 7 64-bit using Visual Studio 2008.
I’ve tried pointing to both the 64-bit and 32-bit DSMs with no real success. For testing I’ve tried both my application and the sample MFC app that comes with the DSM.
The 64-bit DSM won’t load at all in either application. Dependency Walker states that IESHIMS.DLL module is missing.
The 32-bit DSM, located in SYSWOW64 per the readme, loads but hangs when trying to do a scan. The scan progress dialog comes up behind the main app window and nothing happens. If I enable the UI that comes up, but clicking scan from there results in the same hang issue.
If I revert my application to use TWAIN_32.dll directly scanning works as expected.
Tomorrow night I’m going to try some more tests using the older DSMs to see if there are any differences.
Any ideas on the 188.8.131.52 DSM and the issues I’m experiencing?
