Remarks

Using the InvokeHelp method, you can create a custom Help system that is integrated with the Visio Help system. To enable your custom Help to appear in the same MSO Help window as Visio Help, do not specify a window definition in the bstrHelpFileName argument.

The arguments passed to the InvokeHelp method correspond to those described in the HTML Help API. For a list of command values, see the HTML Help API Reference on MSDN, the Microsoft Developer Network. Microsoft Visual Basic programmers can use the numeric equivalent of the C++ constants defined in the HTML Help API header files.

For example, use the following code to display the Visio Help pane:

Application.InvokeHelp "Visio.chm", 15, 0

Or use the following code to hide the Visio Help window:

Application.InvokeHelp "", 18, 0

For more information about the HTML Help API, search for "HTML Help API overview" on MSDN.
