Loading information into text boxes

Is there a way to "automatically" load values into a multitude of text boxes in VB.Net?
In version 6, we did this by using the text boxes’ index numbers in a loop.

I am aware of the tabindex that is available in .Net, but if changes are made to the forms the controls might no longer be indexed contiguously.

Please let me know if anyone has a suggestion.

You could iterate through the forms control collection

Bananafish, thanks for your reply.

Could you elaborate a little on your question?

Thanks

You can also use the ParamArray feature:

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ChangeTextBoxes("Hello", TextBox1, TextBox2, TextBox3)
    End Sub
 
    Private Sub ChangeTextBoxes(ByVal sText As String, ByVal ParamArray textboxes() As TextBox)
        Dim x As Integer
        For x = 0 To textboxes.Length - 1
            textboxes(x).Text = sText
        Next
    End Sub

this is the Control Collection way. Horses for courses I guess...

VB Code:

Dim oCtr As System.Windows.Forms.Control
      For Each oCtr In Me.Controls
         If oCtr.GetType.Name = "TextBox" Then
            If oCtr.Name.StartsWith("txtAutoLoad") Then
               'do whatever
               txtAutoLoadA.Text = "aaa"
               txtAutoLoadB.Text = "bbb"
            End If
         End If
      Next

Thanks for all your help.

Actually - to be more dynamic the following code is better

VB Code:

Dim oCtr As System.Windows.Forms.Control
      Dim oTxt As System.Windows.Forms.TextBox
      For Each oCtr In Me.Controls
         If oCtr.GetType.Name = "TextBox" Then
            If oCtr.Name.StartsWith("txtAutoLoad") Then
               'do whatever
               oTxt = CType(oCtr, TextBox)
               oTxt.Text = "aaa"
            End If
         End If
      Next

What kind of performance hit can this create? I have a form that has over 200 label controls, In VB6 it was easy using a control array, and an array to hold the values, and setting the value was as simple as using the same index for the control ans the underlying value in the array. In .Net I am forced into calling a routine that itterates through the controls collection.

Is ther a way if I know the name of the control to find it, or set it quicker?, I dont really want to have to be stepping through the collection every time to find the correct control?

Control arrays are the one thing I wish they had kept.
