windows 下在一个进程中使用createprocess创建一个窗口进程，并获取这个窗口的HWND句柄

C++使用createprocess创建一个窗口进程，并获取这个窗口的HWND句柄。

主要思路是：

  1. 定义getDwProcessId函数，用于监听创建子窗口的活动。
  2. 定义EnumWindowsProcGetWndTitle回调函数，用于捕获子窗口句柄。
  3. 把捕获的句柄赋值给全局变量，用于主函数执行子窗口操作。

图例如下：

示例如下：

 return 0;

}

BOOL CALLBACK EnumWindowsProcGetWndTitle(HWND hWnd, LPARAM lParam)
{
DWORD ProcID = 0;
GetWindowThreadProcessId(hWnd, &ProcID);
cout << "传入窗口的进程id：" << lParam << "当前窗口的进程id：" << ProcID << endl;

  } else 
  {

  }
  cout << "最终父窗口句柄：" << g_hWnd << endl;
  //ok  pWnd 就是主窗口了。
  return FALSE;

}
return TRUE;
}

DWORD getDwProcessId(DWORD g_dwProcessId)
{
int nNumberDely = 1000;
// 等待窗口动行起，获取到窗口HWND
while(EnumWindows(EnumWindowsProcGetWndTitle,g_dwProcessId) && nNumberDely>0 )
{

  nNumberDely--;

}
return g_dwProcessId;
}

void Build80Zc(const string& sExe, const string& sPath, const string& sCmd)
{
string::size_type idx;
STARTUPINFO si;
ZeroMemory(&si, sizeof(si));
si.cb = sizeof(si);
memset(&si, 0, sizeof(STARTUPINFO));
si.cb = sizeof(STARTUPINFO);

}

}

  DWORD dwEC = 0;

  CloseHandle(pi.hProcess);
  cout << "关闭编译器成功" << endl;

}
ZeroMemory(&si, sizeof(si));
si.cb = sizeof(si);
ZeroMemory(&pi, sizeof(pi));
}

2. **定义getDwProcessId函数，用于监听创建子窗口的活动：**

  
  
  
  
  
//监听创建子窗口的活动
DWORD getDwProcessId(DWORD g_dwProcessId)
{
int nNumberDely = 1000;
// 等待窗口动行起，获取到窗口HWND
while(EnumWindows(EnumWindowsProcGetWndTitle,g_dwProcessId) && nNumberDely>0 )
{
    nNumberDely--;
}
return g_dwProcessId;
}
  1. 定义EnumWindowsProcGetWndTitle回调函数，用于捕获子窗口句柄：

//定义EnumWindowsProcGetWndTitle回调函数，用于捕获子窗口句柄
BOOL CALLBACK EnumWindowsProcGetWndTitle(HWND hWnd, LPARAM lParam)
{
DWORD ProcID = 0;
GetWindowThreadProcessId(hWnd, &ProcID);
cout << "传入窗口的进程id：" << lParam << "当前窗口的进程id：" << ProcID << endl;
cout << "当前窗口句柄：" << hWnd << endl;
if (ProcID == lParam)//如果窗口的processid等于你的ID
{

  HWND pWnd = GetParent(hWnd);
  cout << "第一父窗口句柄：" << pWnd << endl;
  while (GetParent(pWnd) != NULL)//得到父窗口的句柄
  {
      pWnd = GetParent(pWnd);
      cout << "父窗口句柄：" << pWnd << endl;
  }
  if (pWnd != NULL) 
  {
      g_hWnd = pWnd;
  } else 
  {
      g_hWnd = hWnd;
  }
  cout << "最终父窗口句柄：" << g_hWnd << endl;
  //ok  pWnd 就是主窗口了。
  return FALSE;

}
return TRUE;
}
