DOCUMENT:Q151389 11-JAN-2001 [vbwin] TITLE :PRB: Code Example in Online Help on HelpContextID Gives Error PRODUCT :Microsoft Visual Basic for Windows PROD/VER:4.00 | 4.00 OPER/SYS: KEYWORDS:kbref kbDocs ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Standard Edition, 32-bit, for Windows, version 4.0 - Microsoft Visual Basic Professional Edition, 16-bit, for Windows, version 4.0 - Microsoft Visual Basic Professional Edition, 32-bit, for Windows, version 4.0 - Microsoft Visual Basic Enterprise Edition, 16-bit, for Windows, version 4.0 - Microsoft Visual Basic Enterprise Edition, 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 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.
