Process User defined thread message?

[tangjun]

How to process the user defined thread message that was sent by another thread in the unmanaged code?

The worker thread is written with unmanaged c++ (MFC) and called PostThreadMessage() to send the user defined messages, now I need to catch that message on the c# or managed wrapper side, how do I do that? Any example?

You willl need to add ON_MESSAGE (http://msdn2.microsoft.com/en-us/library/k35k2bfs(VS.80).aspx) entries on message maps for those messages along with the handler funciton.

That's how I do it in MFC. Is there any difference to do it in c++/CLI?

No.

No.


can you post some sample code please?

The messages are thread message, not window message, so I need to create a thread to accept them and I need to customize that thread, while System::Threading::Thread is sealed.

You are probablly confused with the managed/unmanaged part in this issue, I would be surprised if there is also ON_MESSAGE macro in c++/CLI

Well, the thread is written in unmanaged (and MFC) code, where you need to catch the messages first, then you can throw them to managed code anyway you want.
