VC++ 创建进程并等待其退出

CString s = L"C:\\test.exe";

STARTUPINFO si;
ZeroMemory(&si, sizeof(si));

si.cb = sizeof(si);
si.wShowWindow = SW_HIDE;

PROCESS_INFORMATION pi;
ZeroMemory(&pi, sizeof(pi));

BOOL bRet = CreateProcess(NULL, s.GetBuffer(), NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);//
if (bRet)
{
WaitForSingleObject(pi.hProcess, INFINITE);// 等待程序退出

CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);

}
