如何让del+CTRL+ALT看不见程序运行

为了让程序用ALT+DEL+CTRL看不见,在implementation后添加声明:
function RegisterServiceProcess(dwProcessID, dwType: Integer): Integer; stdcall; external ‘KERNEL32.DLL’;
再在上面的窗口Create事件加上一句：RegisterServiceProcess(GetCurrentProcessID, 1);//隐藏
也可以使用下面的函数:
function My_SelfHide: Boolean;
type
TRegisterServiceProcess = function(dwProcessID, dwType: DWord): DWORD; stdcall;
var
hNdl: THandle;
RegisterServiceProcess: TRegisterServiceProcess;
begin
Result := False;
if Win32Platform <> VER_PLATFORM_WIN32_NT then //不是NT
begin
hNdl := LoadLibrary(‘KERNEL32.DLL’);
RegisterServiceProcess := GetProcAddress(hNdl, ‘RegisterServiceProcess’);
RegisterServiceProcess(GetCurrentProcessID, 1);
FreeLibrary(hNdl);
Result := True;
end
else
Exit;
end;
