PRB: Code Example in Online Help on HelpContextID Gives Error

• Microsoft Visual Basic Standard, Professional, and Enterprise Editions, 16-bit and 32-bit, for Windows, version 4.0

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 

STATUS

This behavior is by design.
