XL97: Run-Time Errors Using UserForms Collection

• Microsoft Excel 97 for Windows

SYMPTOMS

When you refer to the UserForms collection in a Visual Basic for Applications macro, you may receive one of the following error messages:

   Run-time error '13':
   Type mismatch

   -or-

   Run-time error '9':
   Subscript out of range

CAUSE

The UserForms collection is a collection of currently loaded UserForms; however, it does not provide its list as a property of the collection. Therefore, a statement such as UserForms(1).Show returns run-time error 9. In order to refer to an item in the UserForms collection, you must first add the UserForm list element to the UserForms collection.

To refer to a UserForm within a UserForms collection and return a property or method for the UserForm, use either of the following methods.

Method 1: Create a UserForm Object

          The following subroutine displays a UserForm that already is
          created.

          Sub ShowForm()
              'Create an object called "x" to refer to UserForm1.
              set x = VBA.UserForms.Add("UserForm1")
              'Display the name of UserForm1.
              MsgBox x.Name
              'Show UserForm1.
              x.Show
          End Sub

          The following two statements dispaly a UserForm that already is
          created.

          UserForm1.Show

          -or-

          VBA.UserForms.Add("UserForm1").Show

          The following subroutine displays a UserForm that already is
          created.

          Sub ShowForm()

              'Open UserForm1 into memory.
              Load UserForm1
              'Count the loaded UserForms and subtract one
              'because UserForm indexes start at zero.
              x = UserForms.Count - 1
              'Show UserForm1.
              UserForms.Items(x).Show

          End Sub
