Sample Macro That Won't Allow User to Cancel Dialog Box (142137)

SUMMARY

In Microsoft Excel, you can create a Microsoft Visual Basic for Applications macro to display built-in dialog boxes, such as the Open or the Save As dialog box. Once this type of dialog box is displayed, a user can cancel it by clicking the Cancel button, pressing the ESC key, or by clicking the control menu. If you want to force a user to take a certain action in the dialog box, you can "trap" the cancellation process; that is, you can design the macro so it will not allow the user to cancel the dialog box.

The "More Information" section of this article contains a macro that requires a user to select a file to be opened in the Open dialog box.

Sample Visual Basic Procedure

   Sub Test()

       Dim X As Boolean

       Do
           X = Application.Dialogs(xlDialogOpen).Show

           ' X returns False if the box is canceled.
           If X = False Then MsgBox "Please select a file to open."

       ' X equals True when you open the file.
       Loop Until X = True

   End Sub

When you run this sample macro, the Open dialog box is displayed. If you try to cancel the dialog box, the macro prompts you with a message box. When you click OK in this message box, you are returned to the Open dialog box. This process continues until you select a file to open.
