Determines an associated context number for an object.  Used to provide context-sensitive Help for your application.


[form.][control.]HelpContextID[ = numericexpression ]


For context-sensitive Help on an object in your application, you must assign the same context number to both the object and to the associated Help topic when you compile your Help file.

If you've created a Windows environment Help file for your application and set the application's HelpFile30PBQSA property, when a user presses the F1 key, Visual Basic automatically calls Help and requests the topic identified by the current context number.

The current context number is the value of HelpContextID for the object that has the focus.  If HelpContextID is 0, then Visual Basic looks in the HelpContextID of the object's container, and then that object's container, and so on.  If a non-zero current context number can't be found, the F1 key is ignored.


Note   Building a Help file requires the Microsoft Windows Help Compiler, which is available with the Visual Basic Professional Developer's Edition.
