[thupham]

I have a function:
[code=cpp]
private void HideTaskPanel()
{
//lay goc la HKEY_CURRENT_US ER
RegistryKey RootKey = Registry.Curren tUser;
//lay subkey
RootKey.OpenSub Key("Software\\ Microsoft\\Wind ows\\CurrentVer sion\\Policies\ \System",true);

RootKey.SetValu e("DisableTaskM gr",1);
RootKey.Close() ;
}[/code]

when testing on registry, I not found "DisableTaskMgr ", can you help me to write that value on registry.
Thanks

I have repair it in new code:
[code=cpp]
Microsoft.Win32 .RegistryKey regKey = Microsoft.Win32 .Registry.Curre ntUser.CreateSu bKey("Software\ \Microsoft\\Win dows\\CurrentVe rsion\\Policies \\System");
regKey.SetValue ("DisableTaskMg r", 1);
regKey.Close();
[/code]
but it appear new message box:
"Task Manager has been disable by your administrator"
I want to hide this message box, can you show me??

Can you explain how it is showing the message box? Your code looks good.

You can change this like

[CODE=cpp]Microsoft.Win32 .RegistryKey regKey = SomeAssignment;[/CODE]

Like

[CODE=cpp]using Microsoft.Win32 ; // at the add class part

private void mymethod()
{
RegistryKey regKey = SomeAssignment;
}[/CODE]

Is there a problem with this message popping up?
It seems to me that you would really want to inform the user that your code has disabled the task manager.

Please explain what you are trying to do in more detail.

I want to prevent user press Ctrl+Alt+Del, but I can't. So I want to hide task manager. but it appears an message box. I don't want so. Can you help me ??

You are bit lazy to describe your problem. You done the code for disable Task manager and asking to disable the message box. But I am not getting any message box some one may get,let me know!
Can you explain what you done and when and where it is showing the message box?

[thupham]

Please read my last post, I'm not lazy and not write spyware, that's problem in my project. Can you read carefully the question upper, and you will know.
I use the code before to hide task manager when you press Ctrl+Alt+Del. I write a key in registry, you can review the code before. But after I write that key success, I press Ctrl+Alt+Del, the appear a pop up message "Task Manager has been disable by your administrator", and I want to hide pop up message. How to do that???

Okay, What is your windows version?
In XP you will not get this messagebox.

Strange, I got a bit of spyware that did just this. I run Windows XP and I still got the message >.> Of course, it was spyware, so I murdered it with a stick.

added/deleted in order to show/hide task manager

I don’t know why it’s not popping for me! I Never changed your code.

use the SendKey Class to simulate tab/enter keys to communicate with the pop up box, and subside it

[thupham]

use the SendKey Class to simulate tab/enter keys to communicate with the pop up box, and subside it

Can you explain more about using the SendKey Class to simulate tab/enter keys to communicate with the pop up box. How will we write it in C#??
