Returns

SUCCESS	The function was successful.

Comments

To display the Twain driver user interface without the scan button, call this function with the bEnable parameter set to true. Then call L_TwainTemplateDlg to display the template dialog.

If you call this function with the bEnable parameter set to false, the template dialog will display the normal Twain user interface, with the scan button.
