Updating textbox.text value when executing code

If i use: Label1.Invoke(Sub() Label1.Text = "Test") this updates successfully however, if i try do: Txt_Response.Invoke(Sub() Txt_Response.Text = "Test") the text only updates after the rest of the code has executed and the thread is free.

Is there an easy way to accomplish this without any extra load?

I didnt want to do the long way but i guess i needed it done!

Basically the fix is below, i have added the ability to provide controls so its dynamic to everything but for the sake of this question, i will provide it for textbox.

Private Delegate Sub ResponseUpdateEventHandler(ByVal message As String)
    Private Sub UpdateResponseBox(ByVal message As String)
        If Txt_Response.InvokeRequired Then
            Txt_Response.Invoke(New ResponseUpdateEventHandler(AddressOf UpdateResponseBox), New Object() {message})
        Else
            Txt_Response.AppendText(message + Environment.NewLine)
        End If
    End Sub

Then just call using: UpdateResponseBox("Connecting to device, Please wait...")
