When you run the Help method in your Visual Basic code, Microsoft Excel displays the specified Help topic. The Visual Basic Help method has the following syntax:
Application.Help "filename", topic_number
Here, filename is the name of the file containing the topic and can include the full path, and topic_number identifies the topic within the Help file. For compiled Help files, topic_number is the number you specify in the [MAP] section of the Help project file. The [MAP] section is described on page 565.
example, in Microsoft Excel for Windows, you might use the following Visual Basic code to display Help topic number 103.
Application.Help "C:\REPORTS\REPORTS.HLP", 103
