How to route MSCOMMCtrl event to a thread

Question

0.00/5 (No votes)

See more:

I am using MSCOMMctrl for serial communication. I am able to get the event notification to the MainFrame.cpp using the EVENT SINK mechanism.

Now I want to get this to my communication thread. I have derived a CCommThread class for CWinThread.

I coded the event sink as follows .

BEGIN_EVENTSINK_MAP(CCommThread,CWinThread)
ON_EVENT(CCommThread, ID_COMMCTRL, 1 /* OnComm */, OnComEvent, VTS_NONE)
END_EVENTSINK_MAP()

The compilation is OK. But not getting the event notification to the thraed.

What I am doing wrong ?

Thanks for any suggestion / advice

I don't know how to solve your problem.

But using the MSCOMM32 OCX control for serial communication is an outdated technology. It must be also installed on the client machine.

I suggest to just use the Windows API functions for serial communication using a worker thread calling SetCommMask and WaitCommEvent to get notifications upon serial port activity.

Solution 1

Create the control from your CCommThread instead of the UI thread.

(I agree with Jochen - that Active X control is ancient.)
