    When the main window is created, call this function to create a status 
     bar on the bottom of it.  Here, we also create a progress bar as a 
     child of the status bar, and then size it in the partition routine. 
 
    Notice that the Win32 API InitCommonControls() must be called before 
     this function in order for CreateWindowEx() to succeed with the 
     window classes that we are using here.
