CreateProcess启动隐藏的外部程序（其实就是CreateDesktop，然后指定STARTUPINFO.lpDesktop）

HDESK hDesk = CreateDesktop(_T("MyDesk"), NULL, NULL, 0, GENERIC_ALL, NULL);
ASSERT(hDesk);
STARTUPINFO si = {sizeof(si)};
si.lpDesktop = _T("MyDesk");
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;
PROCESS_INFORMATION pi = {0};

TCHAR szApp[MAX_PATH] = {_T("F://11.exe")};
if(CreateProcess(NULL, szApp, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi))
{
 CloseHandle(pi.hThread);
 CloseHandle(pi.hProcess);
}
