[RESOLVED] How to update a ToolStripProgressBar from a thread

[HalD]

I have a Windows form that has a StatusStrip that contains a ProgressBar. I want to update the ProgressBar from a thread started by the form when a treeview item is clicked on. I set up a delegate and a method to issue the PerformStep() but the compiler tells me that the ToolStripProgressBar does not contain a definition for Invoke.

How do I update the progress bar?

Thanks in advance,
Hal
