你除非写插件，用户访问你的BS页面的时候要安装这个插件，然后由这个插件去读取客户端本地程序。不过这个插件目测很多浏览器是不支持的。一般只有IE可以用。

使用VB.net编写屏蔽热键的方法有很多中,比如说使用系统的API函数,也可以使用钩子来进行屏蔽.还有一种就是.net带的一种方法,首先来判断所按下去的键,然后再执行操作等事件.比如说:if (e.keycode==keys.D){e.handle=true}在keydown事件里面处理!这样就可以屏蔽了D键. 实例:if ((Control.ModifierKeys == Keys.Alt) (e.KeyCode == Keys.F4))
{
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
{
return;
}
}}以上是使用C#编写的,稍微改下就可以了,在,NET里面都差不多!
按你说的方式，需要用到钩子
建议你用File类进行操作，保存为TXT文件
祝好运，望采纳

.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。
