detect next day

I am working on a program for work and I want it to save files every day, how would I go about detecting if its a new day?

Check if CurrentDate() <> oldCurrentDate ?

right but what am I doing to assign oldcurrentdate? running a loop or using millisecs?

When your app first starts, oldCurrentDate is empty... so you save... otherwise we wait til something exciting happens

Local oldCurrentDate:String

Repeat

    If CurrentDate() <> oldCurrentDate Then

        oldCurrentDate = CurrentDate()

        ' Save stuff

    End If

    ' wait a minute
    Delay(60000)
Forever

thanks I will give it a try.
