因为我用了几个SYSTEM命令顺序执行,然后DOS窗口会连续的弹出来.想要隐藏弹出的DOS窗口.
或者让几个顺序执行的system命令在一个DOS窗口内显示.

利用管道实现控制台程序输入输出的重定向

C/C++ code

实现控制台输入输出重转向的控制程序（或者GUI）
#include "vcl.h"
#include "Windows.h"
#include "stdio.h"
int main(int argc, char* argv[])
{
 SECURITY_ATTRIBUTES sa,sa2; 
 HANDLE hInputRead,hInputWrite; 
 HANDLE hOutputRead,hOutputWrite; 
 
 sa.nLength = sizeof(SECURITY_ATTRIBUTES); 
 sa.lpSecurityDescriptor = NULL; 
 sa.bInheritHandle = TRUE; 
 if (!CreatePipe(&hOutputRead,&hOutputWrite,&sa,0)) 
 { 
  printf("Error On CreatePipe1"); 
  return 1; 
 } 
 
 sa2.nLength = sizeof(SECURITY_ATTRIBUTES); 
 sa2.lpSecurityDescriptor = NULL; 
 sa2.bInheritHandle = TRUE; 
 if (!CreatePipe(&hInputRead,&hInputWrite,&sa2,0)) 
 { 
  printf("Error On CreatePipe2"); 
  return 1; 
 } 
 
 STARTUPINFO si; 
 PROCESS_INFORMATION pi; 
 si.cb = sizeof(STARTUPINFO); 
 GetStartupInfo(&si); 
 si.hStdError = hOutputWrite; 
 si.hStdOutput = hOutputWrite; 
 si.hStdInput = hInputRead;
 si.wShowWindow = SW_HIDE; 
 si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES; 
 
 TCHAR cmd_line[100];
 lstrcpy(cmd_line,TEXT("d://and.exe"));
 DWORD dwWritten;
 if (!CreateProcess(NULL,cmd_line,NULL,NULL,TRUE,NULL,NULL,NULL,&si,π))
 {
#ifdef UNICODE
  wprintf(TEXT("Error On CreateProcess")); 
#else
  printf(TEXT("Error On CreateProcess")); 
#endif
  return 1; 
 } 
 
 CloseHandle(hInputRead);
 CloseHandle(hOutputWrite);
 
 char  szInPut[]= ("12/r/n 34/r/n");// 输入
 WriteFile(hInputWrite, szInPut, strlen(szInPut), &dwWritten, NULL);
  
 char buffer[4096] = {0}; 
 DWORD bytesRead; 
 while (true)
 {
  if(ReadFile(hOutputRead,buffer,4095,&bytesRead,NULL) == NULL) 
  {
   break;
  }
  printf(buffer);// 输出
  Sleep(500); 
 } 
 CloseHandle(hInputWrite);
 CloseHandle(hOutputRead);
 return 0;
}

用什么方法调用控制台程序，同时做到：1.隐藏控制台窗口；2.获取控制台程序的exit status

我用system和_spawnlp，返回值就是exit code，但无法隐藏窗口。
用WinExec(command,SW_HIDE)可以隐藏窗口，但是得不到exit code。

请指点，谢谢~

成功:
PROCESS_INFORMATION pi;
STARTUPINFO si;

// Set up the start up info struct.
ZeroMemory(&si,sizeof(STARTUPINFO));

si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;

CreateProcess(NULL, "d://temp//t.exe ", NULL, NULL, 0,
NULL, NULL, NULL, &si, &pi);
WaitForSingleObject(pi.hThread,INFINITE);
CloseHandle(pi.hThread);
DWORD excode=0;
GetExitCodeProcess(pi.hProcess,&excode);
//excode为返回值
