Now Twain2.0 is availabled.a new problem has occured.I can’t find the same source with Twain2.0 which can be found by Twain1.7 .But I can still find the Twain sample source with Twain2.0.So I confirmed that the installation of Twain2.0 must be successful.The source is Canon A590IS,Can anybody tell me why?
are you using a debugger?

You may have found an issue. By setting an environment variable you can create a log file from the DSM that may help narrow down the issue.
right click “My Computer” | Properties | Advanced | Environment Variables
in “User variables for yourname”, Newvariable name: TWAINDSM_LOG
Variable value: %temp%twain2.logOk | Ok | Ok
Run the sample TWAIN2 application to display the list of DS. Close.
View log file.
Start | run | %temp%twain2.log | okRegards,

**************************************************I tested a Canon Power Shot A460 and it worked.
Canon only supplies TWAIN drivers for Win2000 so that is where I tested. The same for the A590IS. The TWAIN driver will not install on WinXP.I was able to use the Sample TWAIN2 application to see and transfer images from the camera.
