Better late than never... While working on a calendar "glued to the desktop", I ran into the same problem. Here is a working solution: /************ win32 interop stuff ****************/ [DllImport( "user32.dll", SetLastError = true )] static extern int SetWindowLong( IntPtr hWnd, int nIndex, IntPtr dwNewLong ); [DllImport( "user32.dll", SetLastError = true )] static extern IntPtr FindWindow( string lpWindowClass, string lpWindowName ); [DllImport( "user32.dll", SetLastError = true )] static extern IntPtr FindWindowEx( IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle ); const int GWL_HWNDPARENT = -8; /************* in Form_Load or equivalent ***************/ IntPtr hprog = FindWindowEx( FindWindowEx( FindWindow( "Progman", "Program Manager" ), IntPtr.Zero, "SHELLDLL_DefView", "" ), IntPtr.Zero, "SysListView32", "FolderView" ); SetWindowLong( this.Handle, GWL_HWNDPARENT, hprog ); The tricky part was to set the form's owner (SetWindowLong + GWL_HWNDPARENT) instead of the form's parent (SetParent). This fixed the form not being rendered on an aero desktop.

well my friend, it is imposible to create this type of a winform, but what you can do is build an active desktop application like this: http://www.codeproject.com/KB/dotnet/DesktopWidget.aspx active desktop application is not under the rules of the minimize window, its above it. hope this helps
