Hello Bahadir,

It's Nice seeing the same surname ! Ha! Ha!

See about it there are 2 differenct concepts you are talking about
1) T.S.R and 2) System Tray

For the T.S.R. (Terminated Stay and Resident) Programmes you obviously
in V.F.P using Timer Control and fire the event from your timer method
from that control

for

2) System Tray there are the utilities available or you can call the
functions from Some .Dll's (in MVCRT.DLL) or you can find it from
.Fll's (Systray.fll)

Regards
Raj
