Re: CWinThread termination
Scott,
thank you for the suggestion. Time consuming operation is not loop based.
Basically (// time consuming operation here)s is an WinHTTP call to a server
script and it may take up to a minute to execute the script on a server. It
is possible to timeout on an Http request function, but this is not what I
want, I need to halt -> terminate thread immideately.
2-nd question : is presence AfxEndThread a bug ?
Thank you!

Run Function in the thread derived class looks like:

I need to terminate this thread via user action while the operation is in
progress. There is no memory allocation, other threads, etc. in the ( //

What would be the best way to do that? TerminateThread? then what do I do
about the lock?
You can use a bool or SetEvent to signal the thread to exit. It should
detect the signal and then exit in the normal way. Something like this...
// time consuming operation here
while (!bThreadExit)
{ ...one step or loop of operation
}
lock.Unlock();
return 1;
You should also get rid of AfxEndThread so the return statement can
perform normal stack allocation cleanup.
