使用CreateProcess创建新的process 并返回process运行结束返回值

转载这篇主要是记住：获得create的新进程运行结束时的返回值的方法

如下：

1.  
   #include <malloc.h>
2.  
    
3.  
   DWORD run_Execute(LPCTSTR lpszFile, LPCTSTR lpszParam)
4.  
   {
5.  
   DWORD exitCode = 0;
6.  
   PROCESS_INFORMATION pInfo = {0};
7.  
   STARTUPINFO sInfo = {0};
8.  
   sInfo.cb = sizeof(STARTUPINFO);
9.  
   sInfo.wShowWindow = SW_SHOW;
10.  
     
11.  
    int nCmdLen = (_tcslen(lpszFile) + _tcslen(lpszParam) + 2) * sizeof(TCHAR);
12.  
    LPTSTR lpszCmd = (LPTSTR)_alloca(nCmdLen);
13.  
    memset(lpszCmd, 0, nCmdLen);
14.  
    _tcscpy(lpszCmd, lpszFile);
15.  
    if(lpszParam)
16.  
    {
17.  
    _tcscat(lpszCmd, _T(" "));
18.  
    _tcscat(lpszCmd, lpszParam);
19.  
    }
20.  
     
21.  
    if(CreateProcess(
22.  
    NULL, //LPCTSTR lpApplicationName, // pointer to name of executable module
23.  
    lpszCmd, //LPTSTR lpCommandLine, // pointer to command line string
24.  
    NULL, //LPSECURITY_ATTRIBUTES lpProcessAttributes, // process security attributes
25.  
    NULL, //LPSECURITY_ATTRIBUTES lpThreadAttributes, // thread security attributes
26.  
    FALSE, //BOOL bInheritHandles, // handle inheritance flag
27.  
    0, //DWORD dwCreationFlags, // creation flags
28.  
    NULL, //LPVOID lpEnvironment, // pointer to new environment block
29.  
    NULL, //LPCTSTR lpCurrentDirectory, // pointer to current directory name
30.  
    &sInfo, //LPSTARTUPINFO lpStartupInfo, // pointer to STARTUPINFO
31.  
    &pInfo)) //LPPROCESS_INFORMATION lpProcessInformation // pointer to PROCESS_INFORMATION
32.  
    {
33.  
    // Wait until child process exits.
34.  
    WaitForSingleObject( pInfo.hProcess, INFINITE );
35.  
     
36.  
    if (GetExitCodeProcess(pInfo.hProcess, &exitCode))
37.  
    {
38.  
    TRACE( _T("Exit code = %d/n"), exitCode);
39.  
    }
40.  
    else
41.  
    {
42.  
    TRACE( _T("GetExitCodeProcess() failed: %ld/n"), GetLastError());
43.  
    ASSERT(0);
44.  
    }
45.  
     
46.  
    // Close process and thread handles.
47.  
    CloseHandle( pInfo.hProcess );
48.  
    CloseHandle( pInfo.hThread );
49.  
    }
50.  
    else
51.  
    {
52.  
    TRACE( _T("CreateProcess() failed: %ld/n"), GetLastError());
53.  
    ASSERT(0);
54.  
    }
55.  
     
56.  
    return exitCode;
57.  
    }

1.  
   //测试示例
2.  
   run_Execute(_T("notepad.exe"), _T("c://temp//aa.txt"));
