启动一个程序，并等等进程运行结束

方法一: 

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = szFile;
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess,INFINITE);

方法二:

PROCESS_INFORMATION ProcessInfo;
STARTUPINFO StartupInfo; //This is an [in] parameter
ZeroMemory(&StartupInfo, sizeof(StartupInfo));
StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field
if(CreateProcess(szFile, NULL,NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo))
{
　  WaitForSingleObject(ProcessInfo.hProcess,INFINITE);
　　CloseHandle(ProcessInfo.hThread);
　　CloseHandle(ProcessInfo.hProcess);
}
