Within a With <obj> / End With block, is there a keyword to access <obj> directly?

In VB.NET, just wondering if there is a kind of "this" keyword, with which one can access the object being used with in With <obj> ... End With block. Eg:

With myObj
  .thisMethod()
  someFunction(<this>) ' Where "<this>" refers to myObj
  .thatMethod()
End With

It would just be handy if it were possible, in those times you want to pass myObj without leaving the With block.

You can't do that directly no. The only way I can think of doing this is to extend your object to include a reference to itself as a readonly property:

Public Class TextBoxExtended
    Inherits TextBox
    Public ReadOnly Property ObjRef As TextBox
        Get
            Return Me
        End Get
    End Property
End Class

You can then do this in your with Block:

With myObj
  .thisMethod()
  someFunction(.ObjRef)
  .thatMethod()
End With

However I would have to question why you would want to do this.

I don't quite follow you. Why can you refer to the object?

For example if that was a textfield.

With textbox1
.visible = true
.text = textbox1.text
End with

That would still work.

in fact this would also work.

.text = .text

Maybe not the best as you will never see a change...

Lets try one more relevent...

' The function to send to.
Function myfunction(thestring As String) As String
    thestring += "moretext"
    Return thestring
End Function

' The with statement
With Textbox1
.Text = myfunction(.Text)
End With

The textbox text will change to the original text + "moretext".
