I would use a Timer control on a form.
Option Explicit
Dim NextTime As Date 
Private Sub Form_Load()
    DoAction
    NextTime = DateAdd("n", 15, Now)
    Timer1.Interval = 60000 'one minute
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
    If Now >= NextTime Then
        DoAction
        NextTime = DateAdd("n", 15, Now)
    End If
End Sub

Sub DoAction()
'CheckWebsite
'...
End Sub

Open in new window


Note. Post submission edit.  Corrected time unit from "m" (month) to "n" ( minute)

Thanks  GrahamSkan, but that seems to only work one time: On form load

Why don't you write a simple program that checks it once and put it in Scheduled Tasks to run every 15 minutes?  That way, you don't have to write the timing part.

DaveBaldwin's suggestion is another good way of doing the job. However I will try to debug my own VB solution.

Well it worked with the revised (test-only) interval value set to 2
Option Explicit
Dim NextTime As Date
Const intervalminutes = 2
Private Sub Form_Load()
    DoAction
    NextTime = DateAdd("n", intervalminutes, Now)
    Timer1.Interval = 60000 'one minute
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
    If Now >= NextTime Then
        DoAction
        NextTime = DateAdd("n", intervalminutes, Now)
    End If
End Sub
Sub DoAction()
MsgBox "executing action now"
'CheckWebsite
'...
End Sub

Open in new window

You don't need code to schedule tasks, but I'll leave DB to explain how easy it is.

Thanks.

I should remember that "m" doesn't always mean "month" in the general consideration of timecode interpretation.

Scheduled Tasks is in the Windows Control Panel.  Open it up and click on Add Task.  A 'wizard' dialog opens up and you follow the instructions.  On Windows XP, the smallest time interval is an hour though.
