Hello,

If you put the following code in your project, what exactly do get in the output debug window?
+----------------------+
Private Sub twnSession_SaveTemplate(ByVal sender As Object, ByVal e As Leadtools.Twain.TwainTemplateEventArgs) Handles twnSession.SaveTemplate
Debug.WriteLine("SaveTemplate: " + e.Capability.Information.Type.ToString())
End Sub

Private Sub twnSession_LoadTemplate(ByVal sender As Object, ByVal e As Leadtools.Twain.TwainTemplateEventArgs) Handles twnSession.LoadTemplate
Debug.WriteLine("LoadTemplate: " + e.Capability.Information.Type.ToString())
End Sub
+----------------------+

Also, do you get any exception when you call the m_TWainSession.LoadTemplateFile method?

Thanks,
