Continuous update feature/event - vb.net

Question

Is there some kind of update feature like in C# for Visual Studio 2012 in vb.net? (so that it will continuously check to see if an if statement is fulfilled)

Answer 1

Try something like this:
Dim iClicks As Integer = 0
Private Sub Label1_Click(sender As Object, e As EventArgs) Handles Label1.Click
iClicks += 1
Label1.Text = iClicks.ToString()
If iClicks = 1000 Then
MessageBox.Show("1000 reached!")
End If
End Sub
It's better to have a integer counter than checking the string value and performing conversion each time. As you can see, the code checks the click counter each time you click the label.
If you want to check the value periodically, add a Timer and perform the check in its event:
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
If iClicks = 1000 Then
MessageBox.Show("1000 reached!")
End If
End Sub
But consider the need to do this, because maybe it's not necessary and will decrease the performance comparing it with the other way.

Answer 2

There is probably a better way of doing this, but what I've done when I need a constant "update" function, is just use a Timer, then handle the Ticks.
Easiest way of implementing it is to go to the form designer, in the Toolbox, under Components, drag a timer onto the form. Double-click it to add a handle for its Tick event.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Timer1.Start()
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
If WhateverYoureLookingFor = True
'Do stuff
End If
End Sub
This is obviously VB, but easy to convert to C#.
