Getting "real" client-area of a FrameWnd

Hi!

I'm trying to get the size of the "real" client-area of the Framewindow of my MDI-application. That means the rectangle excluding all toolbars, statusbars and the menu.

I would be very pleased if somebody could help me

Regards

Try GetClientRect()

I'm using GetClientRect(), but that's the client rect only excluding the menu, but not toolbars or statusbars, I'm looking for a way to get the size of the rect where MDI-child-windows can appear independent of the docking status of the toolbars or statusbar.
The function SetWindowPos(...) uses this rect, but I don't know how to get the size of the rect
