Hi,

I'm trying to add "Cascade" windows functionality in a C# SDI application,
using the win32 API call:

WORD CascadeWindows(          HWND hwndParent,
   UINT wHow,
   const RECT *lpRect,
   UINT cKids,
   const HWND *lpKids
);

I've being trying to use the API in the following way, however it is not
cascading the four windows I am passing to it in the windowArray parameter,
instead it cascades my version of Visual Studio that the Application is
being run from:

[DllImport("user32")] public static extern short CascadeWindows(int
hwndParent,
       int wHow, int lpRect, int cKids, ref System.IntPtr[] lpKids);

public void Cascade(Form[] arrangeWindows )
{
   int index = 0;
   System.IntPtr[] windowArray = new
   System.IntPtr[arrangeWindows.Length];
   foreach(Form arrangeWindow in arrangeWindows)
  {
           windowArray[index++] = arrangeWindow.Handle;
   }

   User32.CascadeWindows(0, 0, 0, windowArray.Length, ref windowArray);
}

Any ideas what I am doing wrong?

Thanks in Advance for any Help :-)-Peter Mc
