SYMPTOMS
When using the RichTextBox control (richtx32.ocx), setting the Font property will cause the following message to be displayed:

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.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Studio 97 Service Pack 2.

For more information on the Visual Studio 97 Service Pack 2, please see the following article in the Microsoft Knowledge Base:

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 RichTextBox1.Font="fixedsys" End Sub

 Compile the project into an EXE. Take this EXE to a machine that has Visual Basic 5.0 and run the application.
