Re: function pointers and callback functions ?

I don't normally use function pointers or callback functions, but I have
a function that uses a function pointer to read the value of a sensor
attached to a board that reads analog inputs of the sensor. Now, I have
attempted to convert it to MFC, but I have not yet been successful. Now,
I was reading on the Internet that using callbacks in MFC is not
recommended, but I was wondering what would I use if not a callback.
What I want to do is to capture the input anytime the control is moved
and to display numerical values in a text box or maybe even use a
progress bar. But the program could be doing something else at the same
time and I was wondering how to capture it so that it is displayed at
the time the control is moved.
