Passing variable from one form to another in vb.net

Question

I've looked this question up 10 times but each answer is too specific to the question. I have two public classes, one per form. The first form has a textbox and two buttons: ``` Public Class frmAdd Public addvar As String Public Sub UltraButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddNote.Click If txtAdd.Text = String.Empty Then MsgBox("Please complete the notes textbox!") Else addvar = txtAdd.Text MsgBox(addvar) Close() End If End Sub Public Sub UltraButton2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click Me.Close() End Sub End Class ``` In the second form I want to take that addvar variable and say ``` Public Sub saveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addButton.Click frmAdd.show() me.textbox1.text = addvar ``` How do I get this to work in vb.net?

Accepted Answer

You need to read the field out of the `frmAdd` value

```
Me.textbox1.Text = frmAdd.addvar
```

Note that this value won't be available until the form has completed, and is closed (`Me.close`). Hence you want to use `ShowDialog` (doesn't return until form is closed) vs. `Show` (which returns immediately after displaying the form).

```
frmAdd.ShowDialog()
Me.textbox1.Text = frmAdd.addvar
```
