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,

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.
