Sudoku array-problem

[Joe]

Hi, I am creating a sudoku on VB Dot Net but to set all textboxes to its
standard I have this code below.
I want to set this in an array but I don't know how to work with arrays.
Could someone help me?
Sincerely Thanks

What I really search is an easy way to make this code shorter?

If these controls are on a Windows Form, you can just iterate throught the
Controls collection:

For Each ctl as Control in Me.Controls
If TypeOf ctl is TextBox Then
'The Select Case is here in case there are other TextBoxes on the
Form.
Select Case ctl.Name.Substring(0,1)
Case "A","B","C","D","E","F"
CType(ctl,TextBox).ReadOnly=False
CType(ctl,TextBox).Clear()
End Select
EndIf
Next

The syntax is probably not correct, but I'm sure you get the idea:

Dim boxes() as new TextBox() = {A1,A2,...,I8,I9}
ForEach box As TextBox in boxes
box.ReadOnly = False
box.Clear()
Next
