HANDLE: A Window Handle IE: Me.Handle. In most applications you can use nothing but on Citrix and WTS, this must be a top-level window or a child of a top level window.

Return Value

True if success, else False -> Use TwainGetLastResultCode() and TwainGetLastConditionCode() methods for diagnosing the error.

Remarks

This will fail if the Source Manager is open. If success, the twain state must be 1 (TWAIN_PRESESSION). To get the TWAIN state, use the TwainGetState() method.
