PRB: ClassWizard Uses WM_HELPINFO Instead of WM_HELP

 Last reviewed: June 26, 1997
Article ID: Q140676
The information in this article applies to:
  • The Microsoft Foundation Classes (MFC) included with: - Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1, 4.2, 5.0

SYMPTOMS

When you use ClassWizard to add a handler for the WM_HELP message, the message is not listed in the Messages list box. Instead, the message is listed as WM_HELPINFO.

RESOLUTION

Select WM_HELPINFO to add a handler for WM_HELP.

MORE INFORMATION

Previous versions of MFC define OnHelp as the function to handle the WM_COMMAND message with ID_HELP. To avoid conflicts with this message handler, MFC 4.x and higher use OnHelpInfo as the name of the function that handles the WM_HELP message. So ClassWizard shows the WM_HELP message as WM_HELPINFO.
