How to change pane text of status bar from a thread in MFC?

Question

I have a dialog in MFC with a CStatusBar. In a separate thread, I want to change the pane text of status bar. However MFC complains with asserts? How is it done? An example

You should use a message (either with Send- or PostMessage) to notify the UI thread that the status bar text should be updated. Don't try to update UI elements from a worker thread, it's bound to give you pain.
