I'm using MSVC++ V1.52
Trying to set up a simple 1 sec timer.

On the line "ON_WM_TIMER()", which the tool inserted,
I get the following compile error:

"error C2642: cast to pointer to member must be from related pointer to member"

This works OK in another class, but not this one.

Thanks,

Are you sure that your class delivered from CWnd class?

I believe you are trying to use a timer in a class not derived from CWnd. Such a class is for instance CDocument. You should use the associated view-class for your timer or the MainFrame CMainFrame. You should use the classwizzard to add the generic handler and message-map-entries for the WM_TIMER-message.
