WebHelp Context-sensitive Help for Visual Basic applications Use this information to connect context-sensitive WebHelp or WebHelp Pro topics to Visual Basic applications.

The ShowHelp function has two parameters: strTopic takes a URL or local filename as a value, and bIsLocal takes a Boolean value. It indicates whether the first parameter is a local filename (TRUE) or remote URL (FALSE). If the file is local, ShowHelp tells the browser to find the file in the Help subfolder of the application folder. Public Function ShowHelp(strTopic As String, _ bIsLocal As Boolean) As Boolean Dim strDir As String If bIsLocal Then ' Get registry entry pointing to Help strDir = App.Path + "\Help\" End If ' Launch topic Dim hinst As Long hinst = ShellExecute(Me.hwnd, vbNullString, _ strTopic, vbNullString, _ strDir, SW_SHOWNORMAL) ' Handle less than 32 indicates failure ShowHelp = hinst > 32 End Function To call ShellExecute , declare the function.
