In Windows 2000, this behavior does not occur: Programs do not generate errors when they are cancelled.
Or, to resolve this problem, obtain updated drivers from the manufacturer of your third-party programs.
With a modal data source you have three options for TWAIN return codes:
- Failure: An error occurred that prevents the TWAIN data source from transferring data.
- Success: All settings are complete, and the operation is ready for a data transfer.
- Cancel: The user has closed the user interface and does not intend to transfer data. (The operation is either cancelled or closed.)
The programs that misinterpret the return codes can cause the error messages to be displayed. A user can read the error messages and follow the actions that are stated by the program to attempt to correct the problem, but the attempts by the user to correct a perceived problem are unnecessary.
