[AccessD] Wake up Call Program

Dear Friends,

I really need some help for my problem :-(

I want to create a small application that will dial a phone and play wav
file to make a wake up call. I already found windows TAPI OCX to do this
things. My problem just in timer event. Let say i have tblPhoneCall with
this field :

Date            Time        Extention
01/01/04    14:00       100
01/01/04    14:05       120

How can i use ontimer event or other trick so when the current time equal to
tblphonecall.time the program will run phone dial function ?  Please help.

Thank you very much !
