Accessing a device context that allows you  to draw on the entire document area, and not just the viewable portion of it.

How can I access the  device context that allows you  to draw on the entire document area, and not just the viewableportion of it. CScrollView::OnDraw provides you with a pDC that represents the entire document area, and not just the viewable portion of it. That is what I need, but I need this from within a CScrollView command handler function. Can I access a device context such as this from within a  command handler function? Basically, right now I am coding my command handler, and the next step is for me to output an array of points to the device context that represents the  entire document area, and not just the viewable portion of it.

You can get access to the overall device context, no matter viewable section or not.
My suggestion is that you handle your command by processing data in your document or CScrollView derived objects, and output your array points by calling OnUpdate() member function, and draw them in OnDraw() overrode function.
Make sure SetScrollSizes() function is called for specifying your document size needed for your application.
