XL97: No Data Validation Property for UserForm TextBoxes

• Microsoft Excel 97 for Windows

SYMPTOMS

When you add a TextBox control to a custom UserForm, you cannot use a property to automatically validate the data that is typed in the TextBox when you run a macro that displays the UserForm.

CAUSE

In Microsoft Excel 97, you cannot use a property that allows you to validate the data. This behavior is different from earlier versions of Microsoft Excel. In earlier versions, you can set the InputType property for an Edit Box control that you place in a custom dialog box.

RESOLUTION

To validate the data that is typed in a TextBox on a custom UserForm, create an event-driven macro that verifies the data. Please see the "More Information" section in this article for an example that shows you how to implement such a macro.

1. Create a new workbook. Point to Macro on the Tools menu, and click Visual Basic Editor to start the Visual Basic Editor.



2. In the Visual Basic Editor, insert a new UserForm into your project.



3. If the Toolbox is not visible, click Toolbox on the View menu.



4. Click TextBox in the Toolbox, and then draw a TextBox on the UserForm.



5. Double-click the TextBox.



6. Type the following code in this Visual Basic module:




       Private Sub TextBox1_Change()

           Dim okstop As Boolean
           Dim yesno_continue As Boolean
           Dim mytext As String

           okstop = False

           Do
               mytext = TextBox1.Value
               If Not IsNumeric(mytext) And mytext <> "" Then
                   TextBox1.Value = ""    'Clears the TextBox

                   'Shows a message box that informs you that you typed
                   'something other than a number.
                   yesno_continue = MsgBox("Please type only numbers." & _
                       Chr(13) & "Continue?", vbYesNo)
               Else
                   okstop = True   'You typed a number in the TextBox.
               End If

           'Continue with the loop if you click Yes.
           'Stop the loop if they typed a number in the TextBox.
           Loop Until (yesno_continue = vbNo) Or (okstop = True)

       End Sub 

7. On the Insert menu, click Module.
   
   This step inserts a module sheet into the project.



8. On this module sheet, type the following code:




       Sub Data_Validate()
           UserForm1.Show  'Displays the custom UserForm.
       End Sub 

9. Run the Data_Validate macro.
   
   Your custom UserForm appears. If you type a number in the TextBox, nothing happens. If you type a text string in the TextBox, the message box in the macro in step 6 appears, informing you that you did not type a number.



10. Click the Close button in the upper-right corner of the UserForm window to dismiss the UserForm.
