'Basically, dimension the timer on your form
Friend WithEvents Timer As System.Windows.Forms.Timer
'Create the timer in InitializeComponents() and set the interval on the timer
Me.Timer = New System.Windows.Forms.Timer(Me.components)
Me.Timer.Interval = 6000
'Enable it when you load your form
Timer.Enabled = True
'put your code to do something fun in the Timer_Tick event
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Timer.Tick
'fun code here
End Sub
Or you can use Thread.Sleep in a loop. This will halt execution for
the specified time
Do
'Code here
Thread.Sleep(10000) 'number of milliseconds
Loop Until bDone
