How do I choose to display Plotting Area in CHM files upon launching from VB.NET?

I'm successfully opening my CHM files from VB.NET.  And seleting topics...etc...

Is there a way to open a CHM file from VB.NET where I can choose whether to display the left Plotting Area or not upon launching?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

How are you showing the CHM?

        'Set up Help class
        HTMLHelpClass.HelpNamespace = HTMLHelpClass.GetLocalHelpFileName("GTime.chm")
        HelpProvider1.HelpNamespace = HTMLHelpClass.GetLocalHelpFileName("GTime.chm")
        If My.Settings.FirstExecution Then
            Help.ShowHelp(Me, HTMLHelpClass.HelpNamespace, HelpNavigator.TopicId, "300", )
        End If

The HelpNavigator class does not seem to support any property to hide that area.
