How to get list of available sources without driver window

[Duddits]

Hi All,

I started with using TWAIN in VB.NET (should be addtionally to WIA where not all scanner capabilities are supported). I found a quite comprehensive example. But there the source is selected by driver window. How can I retrieve this list without usage of this window?

Best Regards

Hi Duddits…

Check out DG_CONTROL / DAT_IDENTITY / MSG_GETFIRST and DG_CONTROL / DAT_IDENTITY / MSG_GETNEXT. The TW_MEMREF argument is a pointer to a TW_IDENTITY structure. The TW_IDENTITY.ProductName returned by these calls is the value used by the Data Source Manager to select which driver to open when calling DG_CONTROL / DAT_IDENTITY / MSG_OPENDS…
