Update views from an worker thread

[Stefano Magni]

Hi all,


I'm writing an application that have a worker thread : this thread read data from a serial port; at the end of this thread I must update the views of my program. I call the function "CDocument::UpdateAllViews" from my thread but the application generate an application-error.

How can I update the views from my worker thread ?


Thanks in advance for your answer.

Try posting a user-defined message to the main application window, and creating a message handler (maybe in the document itself) for that message that calls CDocument::UpdateAllViews. This will ensure that UpdateAllViews is called by the main application thread rather than the worker thread.

For the above proposed solution, If the worker thread throws a user-defined message, how to map so that member function of document is called. If I use AfxGetApp->SendMessage(), then only WinApp derived class can map the message...?

Is there any other way.. thanks for any help.!

You can use AfxGetMainWnd()->SendMessage() to send it to the FrameWnd and handle
the message in the frameWnd. In the handler call UpdateAllviews fn. This will solve the pbm I think.
