ID: Q171510

The information in this article applies to:

Microsoft Visual Basic Control Creation, Learning, Professional, and Enterprise Editions for Windows, version 5.0
Microsoft Visual Basic Standard, Professional, and Enterprise Editions for Windows, version 4.0

SYMPTOMS

Run-time error '438':
Object doesn't support this property or method

This behavior occurs when a RichTextBox is placed on a form using the RichTextBox Control (RICHTX32.OCX) that comes with Visual Basic 4.0 and subsequently executed after the RICHTX32.OCX file has been upgraded to the one that shipped with Visual Basic 5.0.

Steps to Reproduce Behavior

On a Visual Basic 4.0 development machine, create a new project.

Insert a RichTextBox control onto the default form.

In the Form's code window add the following code:


      Private Sub Form_Load()
