SUMMARY
In Microsoft Excel 97, it is possible for a Visual Basic for Applications macro to display a UserForm whose name is stored in a variable. This article explains how this may be done.

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

In Microsoft Excel 97, if you want a Visual Basic macro to display UserForm1, the line of code would be: UserForm1.Show Although this syntax is very simple, it can cause problems if you want to show a UserForm whose name is stored in a variable. For example, if the variable "x" contains the name of the UserForm, you cannot simply use 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 whose name is stored in a variable, you can use the following code: Sub ShowUserForm1 X = "UserForm1" VBA.UserForms.Add(X).Show End Sub

User Prompted for UserForm Name
You can use the InputBox method to ask users what UserForm they want to show: 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: 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 you have 3 UserForms in your 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 your project, you will receive the following error message

Run-time error '424'

and your macro will halt.
