推荐答案

WPF不基于Windows消息.但是，如果您具有窗口句柄(HWND)，则可以将消息发送或发布到任何窗口应用程序.为此，您可以P/Invoke.

请在我对这个问题的回答中查看更多详细信息: [ http://msdn.microsoft.com /en-us/library/ms644950(v=vs.85).aspx [ http://msdn.microsoft.com/en-us/library/ms644944(v = vs.85).aspx [

WPF is not based on Windows messages. However, you can send or post message to any windowed application if you have the Window handle (HWND). For this purpose you can P/Invoke.

Please see further details in my Answer to this Question: A custom-paint WinForm that makes VS 2005 crash when every second time open it in From design view, why?[^]. Take a look at the Answer to follow-up question where I show DLL Imports using System.Runtime.InteropServices.

For details on native Window API, see http://msdn.microsoft.com/en-us/library/ms644950(v=vs.85).aspx[^], http://msdn.microsoft.com/en-us/library/ms644944(v=vs.85).aspx[^].

The above answers the first question about sending a message. Sorry, I fail to understand your second question, please clarify.
