XL: Can't Use xlConstant Names in Variables in VB Code

ID: Q140627

The information in this article applies to:

Microsoft Excel 98 Macintosh Edition
Microsoft Excel 97 for Windows
Microsoft Excel for Windows 95, versions 7.0, 7.0a
Microsoft Excel for Windows, versions 5.0, 5.0c
Microsoft Excel for Windows NT, version 5.0
Microsoft Excel for the Macintosh, versions 5.0, 5.0a

SYMPTOMS

In Microsoft Visual Basic for Applications, string variables that contain Microsoft Excel constant names cannot be used to set properties in Visual Basic code. For example, if you want to show the Open dialog box, the following code will not work:


   Dim var As String
   var = "xlDialogOpen"
   Application.Dialogs(var).show

This type of code, where the Microsoft Excel constant is represented by a variable, produces the following run-time error:

Dialogs Method of Application Class Failed

-or-

Object variable not set

CAUSE

This problem occurs because Microsoft Excel constant names are not actually handled as strings, but rather as the values that they represent.

To set the Microsoft Excel constant values to variables in Visual Basic, an integer variable must be set to the value that the constant name represents, as in the following example:


   Dim var As Integer
   var = xlDialogOpen ' Note the absence of quotation marks.
   Application.Dialogs(var).Show
