问题描述
我要建，鉴于另一个应用程序mainWindowhandle它收集有关窗口状态信息的应用程序。我没有问题，收集有关的子窗口的信息，但我不能访问应用程序，甚至菜单的其他打开的窗口。有没有办法得到一个应用程序的所有窗口句柄？
I'm building an app that given another app mainWindowhandle it collects information about the window state. I have no problem collecting information about child windows, but I can not access the other open windows of an application or even the menus. Is there any way of getting all window handles of an application?
推荐答案
您可以做 Process.MainWindowHandle 似乎做什么：使用P / Invoke来调用<一HREF =http://pinvoke.net/default.aspx/user32/EnumWindows.html> EnumWindows的 功能，调用回调方法，每顶-level窗口系统中的
You could do what Process.MainWindowHandle appears to do: use P/Invoke to call the EnumWindows function, which invokes a callback method for every top-level window in the system.
在你的回调，叫<一href="http://pinvoke.net/default.aspx/user32/GetWindowThreadProcessId.html"><$c$c>GetWindowThreadProcessId,和 Process.Id 比较窗口的进程ID;如果过程的ID匹配，则窗口句柄添加到列表。
In your callback, call GetWindowThreadProcessId, and compare the window's process id with Process.Id; if the process ids match, add the window handle to a list.
