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:

  2. 定义getDwProcessId函数,用于监听创建子窗口的活动:

    ```c++
    //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;
    }
  3. 定义EnumWindowsProcGetWndTitle回调函数,用于捕获子窗口句柄:

    ```c++
    //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;
    }
