Can data source return several TW_IDENTITY to let DSM show several models in the list of data sources?
For example I have superdriver.ds and would like to present several scanners in select data source dailog like following…
TWAIN does not support that.
Your best bet is to do what scanner vendors do when providing a single DS to support many models. They return a somewhat generic name (e.g. “ScanWizard”) in the identity struct and then provide UI when their DS is enabled to allow the user to select a specific scanner.
