Hi, I want to change a label to three different colors according to the timer control.
The code I have so far is:

VB

If Label1.ForeColor = Color.Orange Then
    Label2.ForeColor = Color.White
    Label3.ForeColor = Color.Green
ElseIf Label2.ForeColor = Color.Orange Then
    Label1.ForeColor = Color.Green
    Label3.ForeColor = Color.White
ElseIf Label3.ForeColor = Color.White Then
    Label2.ForeColor = Color.Green
    Label3.ForeColor = Color.Orange
End If

Please help me with the basic stuff.

All you have to do is include a Timer in your program.
You can do it using the designer (drag it from the tool box and set the properties) or in code:

Private Shared WithEvents changeColour As New System.Windows.Forms.Timer()

In your Form Load event:

changeColour.Interval = 500 ' Half a second
changeColour.Start()

And add the handler:

Private Shared Sub changeColour_tick(myObject As [Object], myEventArgs As EventArgs) _
    Handles myTimer.Tick
       If Label1.ForeColor = Color.Orange Then
           Label2.ForeColor = Color.White
           Label3.ForeColor = Color.Green
       ElseIf Label2.ForeColor = Color.Orange Then
           Label1.ForeColor = Color.Green
           Label3.ForeColor = Color.White
       ElseIf Label3.ForeColor = Color.White Then
           Label2.ForeColor = Color.Green
           Label3.ForeColor = Color.Orange
       End If
End Sub

VB

Dim xi As Integer = 0
    Dim yi As Integer = 0
    Dim zi As Integer = 0
<pre lang="vb">Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If xi &lt; 250 Then
            xi = xi + 10
        End If

        If xi = 250 Then
            If yi &lt; 250 Then
                yi = yi + 10
            End If
            If yi = 250 Then
                zi = zi + 10
                If zi = 250 Then
                    zi = 0
                    yi = 0
                    xi = 0
                End If
            End If
        End If
        Label8.ForeColor = ColorTranslator.FromOle(RGB(xi, yi, zi))
        Label9.ForeColor = ColorTranslator.FromOle(RGB(zi, yi, xi))
        Label10.ForeColor = ColorTranslator.FromOle(RGB(yi, xi, zi))
        Label11.ForeColor = ColorTranslator.FromOle(RGB(xi, zi, yi))


    End Sub</pre>
