C#Copy Code
public void TestEnableShowUI(IWin32Window parent) 
{ 
   TwainSession session = new TwainSession(); 
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None); 
 
   session.SelectSource(string.Empty); 
   session.EnableShowUserInterfaceOnly = true; 
   session.ShowTemplateDialog(LeadtoolsExamples.Common.ImagesPath.Path + "test.ltt"); 
 
   session.Shutdown(); 
}

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.
