CView Window ?

[C++ Programming]

Hi, I have a View Class derived from CView, in which I build a Graph. I wanted to be able to rebuild the Graph based on changes in parameters or something. I would have to delete that View window I am assuming before I do a "RebuildGraphPage". How can I delete the windo? Any idea?
I did try Getting Active View window and deleting it, but it caused a crash.

Thanks for any feedback.
