.net的代码真木有写过.
VB 可以屏蔽 包括ctrl+alt+del在内的所有键盘按键消息
其实你只要后台截获按键的消息后,直接屏蔽掉就可以了.
VB代码我有 net木有.
{
e.Handled = true;
}还有一种办法就是不通过屏蔽热键来实现,就是通过设置焦点.你可以把你程序窗口设置为主焦点,这样其他程序一般就无法在你的程序前面了.实现屏蔽的作用.至于任务管理器的话可以通过杀掉进程的办法做到.如下: Process[] p = Process.GetProcesses(); foreach (Process p1 in p)
try
if (p1.ProcessName.ToLower().Trim() == "taskmgr")//这里判断是任务管理器
p1.Kill();
return;
}
catch
}}好了,全部的使用C#编写的,稍微改下就可以了,在,NET里面都差不多!

WH_DEBUG
Installs a hook procedure useful for debugging other hook procedures. For more information, see the DebugProc hook procedure.
WH_FOREGROUNDIDLE
Installs a hook procedure that will be called when the application's foreground thread is about to become idle. This hook is useful for performing low priority tasks during idle time. For more information, see the ForegroundIdleProc hook procedure.
WH_GETMESSAGE
Installs a hook procedure that monitors messages posted to a message queue. For more information, see the GetMsgProc hook procedure.
WH_JOURNALPLAYBACK
Installs a hook procedure that posts messages previously recorded by a WH_JOURNALRECORD hook procedure. For more information, see the JournalPlaybackProc hook procedure.
WH_JOURNALRECORD
Installs a hook procedure that records input messages posted to the system message queue. This hook is useful for recording macros. For more information, see the JournalRecordProc hook procedure.
WH_KEYBOARD
Installs a hook procedure that monitors keystroke messages. For more information, see the KeyboardProc hook procedure.
WH_KEYBOARD_LL
WH_MOUSE
Installs a hook procedure that monitors mouse messages. For more information, see the MouseProc hook procedure.
WH_MOUSE_LL
WH_MSGFILTER
Installs a hook procedure that monitors messages generated as a result of an input event in a dialog box, message box, menu, or scroll bar. For more information, see the MessageProc hook procedure.
WH_SHELL

WH_SYSMSGFILTER
Installs a hook procedure that monitors messages generated as a result of an input event in a dialog box, message box, menu, or scroll bar. The hook procedure monitors these messages for all applications in the same desktop as the calling thread. For more information, see the SysMsgProc hook procedure.
lpfn
[in] Pointer to the hook procedure. If the dwThreadId parameter is zero or specifies the identifier of a thread created by a different process, the lpfn parameter must point to a hook procedure in a DLL. Otherwise, lpfn can point to a hook procedure in the code associated with the current process.
hMod
[in] Handle to the DLL containing the hook procedure pointed to by the lpfn parameter. The hMod parameter must be set to NULL if the dwThreadId parameter specifies a thread created by the current process and if the hook procedure is within the code associated with the current process.
