如何从HANDLE获得CWnd * [英] How to get CWnd* from HANDLE

问题描述

我正在使用ShellExecuteEx从MFC应用程序调用Excel应用程序。我有一个SHELLEXECUTEINFO结构的hProcess，它是一个HANDLE类型。在调用Excel之后，我将再显示一个应该是Excel的子对话框。要将Excel设置为父级，我需要使用Excel的CWnd *但是我有HANDLE的Excel处理。如何获得CWnd *？如果它已经解决了某个链接，我会。我已经尝试过EnumWindows，但不知道给LPARAM带来什么。

提前谢谢。

推荐答案

这不是得到 。与许多典型的MFC类一样，这个类只是一个围绕通过其 HWND 引用的窗口对象的C ++包装器。

请养成一个习惯，自己在文档中查找所有内容。这个论坛更多的是真正的问题，很难或者甚至很简单，但是真的。

It's not "to get". This class, as many typical MFC classes, is a mere C++ wrapper around a window object referenced via its HWND.

Please, get a habit to find everything in documentation by yourself. This forum is more for real problems, hard or maybe even very simple, but real.
