The .NET API offers the Help class in the System.Windows.Forms namespace. Some examples:

Help.ShowHelp(ParentForm, "HelpFile.chm", HelpNavigator.TableofContents, Nothing)
Help.ShowHelp(ParentForm, "HelpFile.chm", HelpNavigator.Index, Nothing)
Help.ShowHelp(ParentForm, "HelpFile.chm", HelpNavigator.Topic, "Page.html")
Help.ShowHelp(ParentForm, "HelpFile.chm", HelpNavigator.TopicId, 123)
Help.ShowHelp(ParentForm, "HelpFile.chm", HelpNavigator.Keyword, "Keyword")
