[Resolved] [2008] Choose which label to write to

Hey, I have a form with 3 labels, a textbox and a button. I want to write a number in the textbox (1-3) and then press the button. Then, if the number in the textbox is 1, I want to write in label1 "TEST", if it's 2 I want to write in label2 etc. I know I can do it with a whole lot of if statements, but I think there has to be a way to do it simply.

I've tried this:

Code:

---

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Label(TextBox1.Text).text = "TEST"
    End Sub

---

But it obviously didn't work...

Hope someone can help :D

vb Code:

me.controls("label" & TextBox1.Text).text = "TEST"

I would be more inclined to put the Labels in an array and then access the desired Label by index based on the value in the TextBox. That way you don't have to name your Labels identically with a numeric prefix.

vb.net Code:

Private labels As Label()
 
Private Sub Form1_Load(ByVal sender As Object, _
                       ByVal e As EventArgs) Handles MyBase.Load
    Me.labels = New Label() {Me.Label1, _
                             Me.Label2, _
                             Me.Label3}
End Sub
 
Private Sub Button1_Click(ByVal sender As Object, _
                          ByVal e As EventArgs) Handles Button1.Click
    Dim index As Integer
 
    If Integer.TryParse(Me.TextBox1.Text, index) Then
        index -= 1
 
        If index >= 0 AndAlso index < Me.labels.Length Then
            Me.labels(index).Text = "TEST"
        End If
    End If
End Sub

isn't that a suffix?

regarding the labels, i'd agree with JMC for many labels, but i'd stick with what i posted for just 3 labels

Thanks both of you, they both worked well
