Property Value

Indicates whether to display the Twain user interface with or without the Scan button, if supported. Possible values are:

true: displays the Twain user interface, without the scan button. false: displays the Twain user interface, with the scan button.

Remarks

To display the TWAIN driver user interface without the Scan button, pass true to this property. Then call ShowTemplateDialog method to display the template dialog. If you pass false to this property, the template dialog will display the normal TWAIN user interface, with the scan button.
