I'm quite new to VC++[5] and I would like some advice...
I am writing a simple program.
I want to create a class  which performs a few bsaic operations but also I can set a timer and catch the timer messages.
Which base class should I use?
Thanks.

What type of program is this? Windows or console?

Is this a dialog application or a document/view app?

If it is a windows program then you can use timers. However, there is no timer class in MFC. Instead check out the API calls SetTimer and KillTimer. You will need override the OnTimer function of either your dialog or MainFrame class in order to catch timer events. Do this by going into the ClassWizard, pick the appropriate class and scroll down the messages list until you find WM_TIMER. Add the function.

I can help you more if you provide a little more information on what you are trying to do!

If the class is for abstract operations, but you need it to be a window, use CWnd as a base class.  If you don't want it to have anything with windows, you don't need to use MFC at all. You can use SetTimer to set a callback form of timer (check it's 4rh parameter).

Please specify exactly what you want to do.
For most purposes, you can use the SetTimer function and map the WM_TIMER message. Write code in the OnTimer() function to do the needful.
