  The sender variable contains a reference to the control, which raised the event, that's a textbox in your case:

  Dim nu As String
  Dim na As String

  Dim textBox As TextBox = DirectCast(sender, TextBox).Name
  na = textBox.Name
  nu = textBox.Text
  Module1.AdSt(nu, na)

  Normally when you create an event handler say for a windows forms application event there are two parameters - normally the first is sender as object and the second is some kind of EventArgs.

  Some examples are

  Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

  End Sub

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click,Button2Click

  End Sub

  The sender is actually identifying which control is initiating this call. As you can hook up the same event to multiple controls or events. So in the 2nd example you could use sender to determine where button1 or button2 was the control which caused the event method to be executed.

  You want to ensure that you are setting the text property

  Textbox1.text = "sdsdsdsd"

  not

  Textbox1= "sdsdsdsd"

  Public Class Form1

  Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) _

  Handles TextBox1.Leave, TextBox2.Leave

  Dim someboxtext As String = CStr((CallByName(sender, "Text", CallType.Get)))

  MsgBox(CStr((CallByName(sender, "Name", CallType.Get))) & someboxtext)

  End Sub

  End Class

  i Think i am missing something when you say sender what do you mean
  

• search and deploy

  This will fail as your trying to assign a string to a textbox, breaking it down into two steps should help.

  Dim textBox As TextBox = DirectCast(sender, TextBox)
  textBox.Name = sender.name

  I'mSorry, had a typo when pasting the code - I forgot to remove .Name from the DirectCast line. Glad you figured it out yourself.

  How about a sample of what you are trying to do You question is not very clear. If you are trying to assign something from a textbox,like the text in the textbox, to another procedure, you will have to reference the Textbox1.Text in the other procedure:

  MyotherValue = Textbox1.Text

  Is that what you are wanting to do
