Question

I am using VB 2010. I have 20 TextBox controls in my form. I turned them to TextBox array.

Here is the code:

Dim TbArray(19) As TextBox
Private Sub Form7_Load(ByVal sender As System.Object, 
      ByVal e As System.EventArgs) Handles MyBase.Load

    TbArray(0) = TextBox1
    TbArray(1) = TextBox2
    ...
    TbArray(19) = TextBox20

It works properly. I want my program to select all the text on the TextBox control which got focused.

How can i know which TextBox control has been selected? I mean there is no Private Sub TbArray(i)_GotFocus in the dropdown menu of vb designer.

To expound on what Akram said,

For x = 0 to 19
   AddHandler tbarray(x).GotFocus, AddressOf TextBox_GotFocus
Next x

Private Sub TextBox_GotFocus(sender As Object, e As System.EventArgs)
    Dim tb As TextBox = CType(sender, TextBox)
    tb.SelectAll()
End Sub
