Just wondering is there a way to enumerate the devices and manually remove the WIA device from the default device select list, because the default twain_32.dll automatically load TWAIN and WIA device into the default select device dialog box.

Basically do not want to show the default device select dialog box, enumerate through all available devices and find the device with prefix WIA then remove it, then display TWAIN only devices ?

Thanks.

The TWAIN Working Group’s open source TWAINDMS.DLL (released more than 10 years ago), which is 100% compatible with the ancient TWAIN_32.DLL filters out the WIA compatibility drivers. There is no way of preventing TWAIN_32.DLL library from showing it.
