SYMPTOMS
========

When you click Cancel in the Bullets And Numbering dialog box that appears when
you run a WordBasic macro that has been converted to a Visual Basic for
Applications macro that uses the FormatHeadingNumbering commands to display the
Bullets And Numbering dialog box, the macro skips the check for the action of
pressing Cancel.

CAUSE
=====

In Microsoft WordBasic you can check for a user clicking Cancel in a dialog box
by testing for a return value of zero. When the WordBasic object is used in
conjunction with a converted WordBasic macro, the value returned is -1 instead
of 0 when you click Cancel.

For example, the following code sample was converted from WordBasic to Visual
Basic for Applications:

     Sub Main()
        Dim dlg As Object
        Set dlg = WordBasic.DialogRecord.FormatHeadingNumbering(False)
        WordBasic.CurValues.FormatHeadingNumbering dlg
        x = WordBasic.Dialog.FormatHeadingNumbering(dlg)
        ' In WordBasic, if the Cancel button was pressed, x will equal zero.
        If x = 0 Then
           ' Because Visual Basic for Applications WordBasic object returns
           '  -1 for Cancel, any commands in this If...Then...Else statement
           ' will be skipped when Cancel is clicked.
           MsgBox "Cancel was pressed."
        End If
     End Sub

To work around this problem, check for the value of -1 instead of zero as in the
following example:

     Sub Main()
        Dim dlg As Object
        Set dlg = WordBasic.DialogRecord.FormatHeadingNumbering(False)
        WordBasic.CurValues.FormatHeadingNumbering dlg
        x = WordBasic.Dialog.FormatHeadingNumbering(dlg)
        ' If the Cancel button was pressed, x will equal -1.
        If x = -1 Then
           ' Perform actions based on the Cancel button being clicked.
        End If
     End Sub

NOTE: Using Visual Basic for Applications commands without the WordBasic object
returns zero for a Cancel button. For example, the following procedure performs
the same functionality as the converted WordBasic macro examples described
earlier in this article:

     Sub ShowDlg()
        ' Display the Bullets and Numbering Dialog.
        With Dialogs(wdDialogFormatBulletsAndNumbering)
           .DefaultTab = wdDialogFormatBulletsAndNumberingTabOutlineNumbered
           x = .Show
        End With
        ' If x=zero then the Cancel button was clicked.
        If x = 0 Then
           MsgBox "Cancel was pressed."
        End If
     End Sub
