SYMPTOMS
========

The Online Help for the HelpContextID Property topic has a code example that
returns an error when used.

The code example for the HelpContextID Property references Context IDs in the
VB.Hlp file is not valid when used with the VB.Hlp file included in Visual Basic
4.0. Depending on the operating system, an error is returned indicating that the
Help file is invalid. The Context IDs are valid using the VB.Hlp file shipped
with Visual Basic 3.0. If that file exists, you can point to it in the sample
code line - "App.HelpFile = "VB.HLP"" in the Private Sub Form_Load() Function.
As an example: App.HelpFile = "C:\VB3\VB.HLP".

CAUSE
=====

The code example for HelpContextID Property topic was not rewritten to use the
Visual Basic 4.0 VB.Hlp file.

RESOLUTION
==========

Use the Visual Basic 3.0 VB.Hlp file or use another Help file for which Context
IDs are known, such as IconWrks.Hlp. The Context ID numbers can be found by
opening the IconWrks.Hpj file in a text editor.

If the Help files mentioned above are not available, the following Context IDs
from the Visual Basic 4.0 VB.Hlp file can be used in place of the Context IDs in
the code example:

       2007557   Command Button Control
       2007560   DirListBox Control
       2007570   FontCount Property

A complete list of the HelpContext IDs in the Visual Basic 4.0 VB.Hlp file is not
available.

STATUS
======

This behavior is by design.
