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.

WORKAROUND

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. 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
