Visual Basic 2010 equivalent of JavaScript numbered variable names

[robertybob]

Hi

I tried to find this via Google but as you can see from the title, I can't get my head round the correct terms to search for.

The issue is as follows - this is an application I'm converting from javascript to VB so would like the direct solution rather than the 'array' solution if it's possible.

In javascript...
var myname = "Billy";
i = 4;
document.getElementById('name'+i).value = myname;
document.getElementById('namebox'+i).checked = true;

The first 2 lines are obviously easy in VB but what is the equivalent of the last 2 lines? I thought it was something like Me.Controls... but can't find a way to get that to work.

Many thanks!

You're in the right spot!

    Private Function FindControl(ByVal controlName As String) As Control
        For Each ctrl As Control In Me.Controls
            If ctrl.Name = controlName Then
                Return ctrl
            End If
        Next
    End Function
 

OR

' Returns control array of matches
Dim ctrl() As Control = Me.Controls.Find(controlName , True)

Many thanks, Mikkeee!

I managed to work through your thinking and have a partial success. The issue now is that, whilst my Label text is processed, it doesn't like the checkbox code. It throws a Checkbox is not a member of Systems.Forms etc.

A simplified version of my code is as follows - the checkbox control fails the build. The form contains Label1, Label2, Checkbox1 and Checkbox2.

Public Class Form1
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim xx = 1
        Dim thislabel = "Label" & xx
        Dim thisbox = "Checkbox" & xx
        Me.Controls(thislabel).Text = "New Text"  'perfect
        Me.Controls(thisbox).Checked = True     ' fails
    End Sub
End Class
 

All the best.

DirectCast(Me.Controls(thisbox), CheckBox).Checked = True

Fantastic - thanks again, Mikkeee.
