[RESOLVED] [2008] Control Arrays in VB 2008

[BKSwindell]

Quick question,

How do I do create control arrays in VB2008. In vb6.0 I was able to do

For i As Integer, 0 to 9, step 1
       txtMSG(i).text = ("I am text box number: " + chr(i + 49))
Next

I need to be able to enumerate through a series of controls in this way.

Thanks

There is, but you have to change the way you think about it. There is no longer a way to create Control Arrays at design time... it has to be done at runtime... and it becomes and array of controls - jsut like any other array. If it's one type, like a button, you can use generics and make it a List (Of CommandButton). - or what ever else you need. And then in the constructor or the load, you have to figure out some way to load them into the array, list, what ever collection you use.

Something similar to this should work:

    Private Shared _dataCols() As DataColumn = {New DataColumn("TrackCode", GetType(String)), New DataColumn("RaceID", GetType(Integer)), New DataColumn("RaceNumber", GetType(String)), New DataColumn("PostTime", GetType(Date))}

As tg says, arrays of controls are just like any other arrays in VB.NET.

Private textBoxes As TextBox()
 
Private Sub Form1_Load(ByVal sender As Object, _
                       ByVal e As EventArgs) Handles MyBase.Load
    Me.textBoxes = New TextBox() {Me.TextBox1, Me.TextBox2, Me.TextBox3}
End Sub

Here is a little example of a way you can do arrays in .net

Add 3 text boxes and execute this code under a button.

        Dim whatever() As TextBox = {TextBox1, TextBox2, TextBox3}
        Dim i As Integer = 0
        '
        For i = 0 To 2
            whatever(i).Text = "simple " & i
        Next

Thanks guys that works perfectly. Will this also work with timers?

As we have stated fairly clearly already, an array is an array, whatever it contains. All arrays work the same way.
