Rich Text Box Progress Display problems

Hi. I have a class that call another class which handles progress
messaging. The progress messaging class has an RTF that's supposed to
display progress messages using the appendtext method.

When I call the progress messaging class, the form pops up, but the rtf
fails to display or show messages. Any idea what the prob might be?
Here's the calling code:

            Dim ProcessUpdates1 As New Progress_Updates

            ProcessUpdates1.Show()
            ProcessUpdates1.ProcessUpdates.BringToFront()
            ProcessUpdates1.ProcessUpdates.AppendText("Please Wait...")
            ProcessUpdates1.ProcessUpdates.Focus()
            ProcessUpdates1.ProcessUpdates.ScrollToCaret()

Of course, "ProcessUpdates" references the RTF

Thanks,

Henry

What do you want to archieve with the line above?

> ProcessUpdates1.ProcessUpdates.AppendText("Please Wait...")

Are you sure you are calling the method from within the thread the control
has been created on?
