I need to disable keyboard/mouse or both for specific time period at system level in my application.

I have following to do that

C#

public partial class NativeMethods
        {

            /// Return Type: BOOL->int
            ///fBlockIt: BOOL->int
            [System.Runtime.InteropServices.DllImportAttribute("user32.dll", EntryPoint = "BlockInput")]
            [return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
            public static extern bool BlockInput([System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)] bool fBlockIt);

        }

By this code the task is complete but when user click on CTRL+ALT+DELETE keyboard and mouse are working again.
Can any body tell me how to stop this??

Have you tried Keyboard and Mouse hook?

But I think that you can't stop using CTRL+ALT+DELETE.
It's universal...

Thanks.
