I agree; But Microsoft promises c# to be the most powerful language after c++ giving control to the System programming. I guess there is a way or atleast is there a way to activate the process immediately if any user kills it. For example in Visual Studio .net IDE, when you create a C# or VB.net Web Application project, you always see wp_.... process in the processes. Even if you kill it, the process comes up right way.. how Can i implement something like this? Even if the user kills my application process, can i re-start it immediately...??

if you want to send a message in c#, here is the way to declare ... [DllImport("user32.dll",EntryPoint="SendMessage",ExactSpelling=false,SetLastError=true)] private static extern int SendMessage(int hwnd,int wMsg,int wParam,int lParam); [DllImport("user32.dll",,EntryPoint="PostMessage",ExactSpelling=false,SetLastError=true)] private static extern int PostMessage(int hwnd,int wMsg,int wParam,int lParam); Hope this helps.. Thanks

Hello all; Is there a way in c#(.net) to hide an application from windows task manager's processess list.. I want my c# application to be invisible in the computer where it is installed. Even if the user goes to task manager using ctrl+alt+del and task manager... Any idea on how to disable ctrl+alt+del key sequence in c# on windows NT and above platforms in c#.. I started developing a application using delphi ( as it can create Global Hook. And i can trap the key sequence and pop up a box when ever ctrl+alt are pressed thus forcing the user to miss del key) and use that DLL in c#. Any ideas & suggestions are appreciated.. Thanks
