XL97: Help Argument for MsgBox Function Behaves Differently

ID: Q164500

The information in this article applies to:

Microsoft Excel 97 for Windows

SUMMARY

In Microsoft Excel 97, when you use the MsgBox function to display a Help button in a message box, the Visual Basic for Applications procedure you use is different from the procedure you use in earlier versions of Microsoft Excel. The MsgBox function requires a new constant, vbMsgBoxHelpButton, to display a Help button. You must use the constant in combination with the Helpfile and Context arguments. In earlier versions of Microsoft Excel, when you use the MsgBox function, no constants are required to display a Help button in a message box. Instead, Microsoft Excel automatically displays a Help button if you provide the information for the Helpfile and Context named arguments.

MORE INFORMATION

The MsgBox function in Visual Basic for Applications displays a message in a dialog box, waits for the user to click a button, and returns an integer that indicates which button the user clicked. The buttons displayed in the dialog box may vary, depending on the constants you use with the MsgBox function.

Example

The following macro example uses the vbMsgBoxHelpButton constant to display a Help button in a message box:


    Sub MsgBox_Help_Example()

       'Dimension variables.
       Dim Msg, Style, Title, Help, Ctxt, Response, MyString

       'Set the values of variables used by the MsgBox Function.
       Msg = "Do you want to create a template?"   'Define message.
       Style = vbYesNo + vbMsgBoxHelpButton        'Define buttons.
       Title = "MsgBox Demonstration"              'Define title.
       Help = "xlmain8.HLP"                        'Define Help file.
       Ctxt = 2017                                 'Define topic context.

       'Display the message box.
       Response = MsgBox(Msg, Style, Title, Help, Ctxt)

       If Response = vbYes Then    'User clicks Yes.
           MyString = "Yes"        'Perform some action.
       Else    ' User chose No.
           MyString = "No"         'Perform some action.
       End If

   End Sub

Issues to Consider When You Upgrade to Microsoft Excel 97

In earlier versions of Microsoft Excel, when you create a file that contains a macro that uses the MsgBox function to display a Help button and you open the file in Microsoft Excel 97, there are several issues to consider. These issues are the following:

The Help button does not appear in the message box until you edit the macro; the macro must use the new constant, vbMsgBoxHelpButton.

The name of the Help file may be different.

The context ID of the Help topic may be different.
