SUMMARY

In Microsoft Excel 98 Macintosh Edition, it is possible for a Visual Basic for Applications macro to display a UserForm with a name that is stored in a variable. This article explains how to do this.

In all following examples, the UserForm being used is called "UserForm1" (without the quotation marks).

In Microsoft Excel 98 Macintosh Edition, if you want a Visual Basic macro to display UserForm1, the line of code to use is the following:

   UserForm1.Show

Although this syntax is very simple, it can cause problems if you want to show a UserForm with a name that is stored in a variable. For example, if the variable "x" contains the name of the UserForm, you cannot simply use the following procedure

   Sub Test()
       x = "UserForm1"
       x.Show
   End Sub

to display UserForm1.

If you run this macro, you receive the following error message:

   Run-time error '424'
   Object Required

UserForm Name Stored in a Variable

If you want to show a UserForm with a name that is stored in a variable, use the following code:

   Sub ShowUserForm1()
       X = "UserForm1"
       VBA.UserForms.Add(X).Show
   End Sub

User Prompted for UserForm Name

To ask a user what UserForm to display, use the InputBox method as in the following procedure:

   Sub ShowUserForm2()
       X = InputBox("Show which UserForm?: ")
       VBA.UserForms.Add(X).Show
   End Sub

UserForm Name Retrieved from Worksheet Cell

You can read a value from a cell in a worksheet by using the following procedure:

   Sub ShowUserForm3()

       'Cell A1 of Sheet1 contains the name of the UserForm
       X = ActiveWorkbook.Sheets("Sheet1").Cells(1, 1).Value

       VBA.UserForms.Add(X).Show
   End Sub

Prompt for Index Number to Display UserForm

You can include a list of UserForm names in your macro and set the value of "X" to the UserForm that corresponds to an index number.

NOTE: The following example assumes that there are three UserForms in the project: UserForm1, UserForm2, and UserForm3. You may want to insert some macro code to make sure the value entered is between 1 and 3, inclusive.

   Sub ShowUserForm4()

       'Display an input box asking for a number between 1 and 3
       '(inclusive).
       Y = Application.InputBox (Prompt:="enter 1, 2, or 3", Type:=1)

       'Based on the number entered in the input box, X will be set to
       'the appropriate string.

       Select Case Y
           Case 1
               X = "UserForm1"
           Case 2
               X = "UserForm2"
           Case Else
               X = "UserForm3"
       End Select

       VBA.UserForms.Add(X).Show
   End Sub

In each case above, the UserForm you want to show must exist. If it does not exist in the project, you receive the following error message

   Run-time error '424'

and the macro halts.
