.net - vb.net Pass Textbox Between forms.

Question

I have 2 forms. On Form1 I want to pass the textbox value to form 2 on load. This is what I thought would work. Form1 will be loaded and running and data will be populated in form1. I am exposing the property of the text box in form1. Then I am trying to use that exposed property in form2.

Public Class form1

Public ReadOnly Property GetTextBox() As String
    Get
        Return txtbox1.Value
    End Get
End Property

On form2

 Dim X As form1
 Me.TextBox1.Text = X.GetTextBox

Answer 1

VB will allow you to refer to instances of forms by their class name, so you'd be able to use:

Me.TextBox1.Text = Form1.GetTextBox

However you should not rely on this and should instead pass an explicit instance of Form1 to Form2, e.g. in a constructor:

' Form2
Public Sub New(ByVal f As Form1)
    Me.New()

    ' save 'f' for future reference
End Sub
