Uncloseable window

Hi, I have a modal dialog that I don't want the user to close via the close button, how do I disable it? Thanks

Override the OnClosing event and set the Cancel memeber of that event argument to true. Rember that just disabling close button won't do the job, user can still use ALT + F4 :) . Stevo

He you can do it by 2 methods, First one is just capture closing event of that form and make e.cancel = true; or second method is you disable closing button using following code, You have to use win32 dll.
const int SC_CLOSE = 0xF060; const int MF_BYCOMMAND = 0x0; [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern IntPtr RemoveMenu(IntPtr menuHwnd, int position, int flags ); [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern IntPtr GetSystemMenu(IntPtr hwnd, int bRevert); public static void EnableApplicationClose( System.Windows.Forms.Form form, bool val ) { IntPtr menu = GetSystemMenu( form.Handle, val ? 1 : 0 ); if ( !val && menu != IntPtr.Zero ) RemoveMenu(menu, SC_CLOSE, MF_BYCOMMAND ); else { // needed when enabling the app close box to force it to redraw. form.Enabled = false; form.Enabled = true; } }Rahul Kulkarni -

Choose a window style without close button: FormBorderStyle.None Having a button (or any GUI element) visible but turned off (without a visual clue) is not good practice. :)

Yup! The entity that can not be used drives the user mad. :mad: :)

and the dialog that can't be closed drives the user to kill process and uninstall. :mad: X|
