DOCERR: AfxMessageBox Missing Information in MFC.HLP

The information in this article applies to:

• The Microsoft Foundation Classes (MFC) included with: Microsoft Visual C++ for Windows, version 1.5

SUMMARY

The help file, MFC.HLP, for the Microsoft Foundation Class (MFC) Libraries is missing information for the AfxMessageBox function. The missing information describes the nType parameter, which is the second parameter to the AfxMessageBox function and describes the style of the message box.

Under Microsoft Visual C++ for Windows, version 1.0, the MFC.HLP file for the MFC Library version 2.0 contains a jump to a description of the values for nType. The MFC 2.5 help file supposedly lists the values for nType in the AfxMessageBox help text, but this text is missing.

RESOLUTION

The message box styles used as the nType parameter are documented in the MessageBox functions for both the MFC and the Windows Software Development Kit (SDK) help files.

MORE INFORMATION

The message box styles used for the nType parameter can be one of the following constants, defined in WINDOWS.H:
