What's the best way to return a value to a class from a form ... for example, a class calls a form to display a text box and the user's input value needs to be returned to the class. I've used global variables in VB6, but they're inelegant!

The code using it can peek at the form's public variables and that includes the controls. So you can do something like this:

    Dim frm As New GetDataForm
    frm.ShowDialog()
    Debug.WriteLine(frm.txtFirstName.Text)
    Debug.WriteLine(frm.txtLastName.Text)

You can also set the form's DialogResult property to let the calling code know if the user clicked OK or Cancel.

Take a look at pages 302-303.
