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：
图例如下：
示例如下：
程序入口点代码
```c++

//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

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;
}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;
