developing a dynamic class timetable

Question

please i want someone to help me out here. i am trying to develop a dynamic class timetable.
Every 2hrs; classes changes lectures and lecturerers. i want my application on its own to be able
to switch to next period, on the process, the next period lectures and the lectureers would display
on the thesame labels that previous lectures displayed. i am using "System.Windows.Forms.Timer" and
"TimerEventProcessor" to trigger the methods that will display the ongoing lectures and the lecturerers.
After so many efforts i made; nothing seemed to happen.
please i need help.
