to remove. go to publishing Designer selects the form and change the property ControlBox to false. to intercept. public const int WM_SYSCOMMAND = 0x0112; public const int SC_CLOSE = 0xF060; protected override void WndProc(ref Message m) { if( m.Msg == WM_SYSCOMMAND) { if( (int) m.WParam.ToInt32() == SC_CLOSE ) { if (ProjectIsOpen) { return; } else { this.Close(); Application.Exit(); } } } base.WndProc (ref m); } :)

hi, first thanks for your reply. second i want to ask you a more detailed question. what if i want to hide only the close button and the maximize button and keep the minimize button. The property ControlBox when set to false hides the three buttons together even if i try to set the maximizebox to true it want appear. i hope u have a solution for that. jamil abou khalil

try it. private const int SC_CLOSE = 0xF060; private const int SC_MAXIMIZE = 0xF030; private const int SC_MINIMIZE = 0xF020; private const int SC_RESTORE = 0xF120; private const int MF_GRAYED = 0x1; [System.Runtime.InteropServices.DllImport("user32.dll")] private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert); [System.Runtime.InteropServices.DllImport("user32.dll")] private static extern int EnableMenuItem(IntPtr hMenu, int wIDEnableItem, int wEnable); private void Disable_opt() { EnableMenuItem(GetSystemMenu(this.Handle, false), SC_CLOSE, MF_GRAYED); EnableMenuItem(GetSystemMenu(this.Handle, false), SC_MAXIMIZE, MF_GRAYED); EnableMenuItem(GetSystemMenu(this.Handle, false), SC_MINIMIZE, MF_GRAYED); EnableMenuItem(GetSystemMenu(this.Handle, false), SC_RESTORE, MF_GRAYED); } :)
