Question : How to refresh the view in an SDI application

I have created a project using the MFC (Visual Studio 2005) SDI Doc/View architecture. In my single view, a have painted the entire client area black and am displaying some green text on it for display.
I would like to refresh this at a set frequency, using the WM_TIMER, to redraw the text that displays, constantly with updated values.
It looks like there is a WM_TIMER that I can get to my view class. But...now how do I indirectly call OnDraw() where my drawing code resides? Or, how to do I get an appropriate CDC like the one that is passed to OnDraw() so I can do the drawing in another function?
Thanks,

You can just call Invalidate() on your window during whichever even causes a need to refresh- this calls paint for you...
