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：
- 定义getDwProcessId函数，用于监听创建子窗口的活动。
- 定义EnumWindowsProcGetWndTitle回调函数，用于捕获子窗口句柄。
- 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：

// 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：**
//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;

cout << "传入窗口的进程id：" << lParam << "当前窗口的进程id：" << ProcID << endl;
