Unlike menus, tool and status bars are seperate controls that live inside the parent window's client area. Therefor if we just leave our WM_SIZE code from before, they are going to overlap with the edit control we added in the previous examples

If so why GetClientRect Function returns the upper-left and lower-right visible corners of the client area? It must be start under toolbar. right?

Is there a way to get handle of clent window(area), so we can move it?
