Refreshing the desktop

I have an application that set the work area of the desktop (Windows API). So I would like to redraw all opened windows.

Did anybody know how to do that ?

Thanks

Redraw or resize?

To enumerate all windows use "EnumWindows". To resize the windows use "SetWindowPos". To refresh them use "InvalidateRect".

Do you know how to resize all windows to fit the new work area (desktop) set by my application ?

Well, for each window do this:

(1) Call "GetWindowRect(window)" to get the window position/size.
(2) See, whether this rectangle fits in your work area. If not, change the rectangle, so that it does fit. Then call "SetWindowPos(window, ...)" to realize the new rectangle.
