umm.  I still have a little  question . Can  I  hide my application name  or change  while hold down   CTRL-ALT_DELETE ?

(when I  set my window  sw_show  , I can change my  application  name but when I set  it to  sw_hide  I can not do that).


please give  advise to me

thank you

To remove your program from the Ctrl+Alt+Delete list do the following:

DWORD dwID = GetCurrentProcessId()
RegisterServiceProcess(dwID, RSP_SIMPLE_SERVICE)

To restore your application to the Ctrl+Alt+Delete list just "undo" it

RegisterServiceProcess(dwID,
RSP_UNREGISTER_SERVICE)

I got a problem when  I use RegisterServiceProcess(dwID, RSP_SIMPLE_SERVICE) . I put it into my application's InitInstance().
and compile  it tell error to me like this

error C2065: 'RegisterServiceProcess' : undeclared identifier.


I use VC6  and win98.   how should I do.

Sorry, I forgot to mention:
to call RegisterServiceProcess, you have to retrieve a function pointer using GetProcAddress on KERNEL32.DLL.
Something like that:

typedef DWORD (WINAPI *RegisterServiceProcess)(DWORD dwProcessId,DWORD dwType);
RegisterServiceProcess fncptr=NULL;
HMODULE hModule = ::GetModuleHandle(TEXT("kernel32.dll"));
fncptr=(RegisterServiceProcess)::GetProcAddress(hModule, "RegisterServiceProcess");
if (fncptr!=NULL)
   (*fncptr)(0, 1);

Thank you for points.
There is no tutorial on this issue in MSDN, you are right. Let me think a little where it could be found.

About NT: I think it is the same, but I have no NT machine to test. Again, let me think about it.
