Parameters

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. If the Source Manager is not open, does nothing and returns TRUE.

Remarks

If success, the twain state must be <= 2 (TWAIN_SM_LOADED). To get the TWAIN state, use the TwainGetState() method.
