Answer 1

You can either add a property to the form or you can add a parameter to your form's constructor.

An example of the first method would look like (where Message is the name of the property)

frm.Message = "Some text"

An example of the second method would look like

Dim frm As New SampleForm ( "Some text" )

Your form code would be something like

Public Class SampleForm

Private someMessage As String


Public Sub New(ByVal msg As String)
    InitializeComponent()

    If Not (String.IsNullOrEmpty(msg)) Then
        someMessage = msg
    End If
End Sub

Property Message() As String
    Get
        Return someMessage
    End Get
    Set(ByVal Value As String)
        someMessage = Value
    End Set
End Property

End Class

Answer 2

3 options: You can create a custom constructor for the dialog and pass it in.

Or add a string property and set it between constructing the dialog and showing it.

Or you can overload the ShowDialog method in your dialog class with one that takes a string argument and in there call to the base ShowDialog().

Answer 3

Try properties, for example setting some text boxes in your dialog:

Property FirstName() As String
    Get
        Return txtFirstName.Text
    End Get
    Set(ByVal Value As String)
        txtFirstName.Text = Value
    End Set
End Property
Property LastName() As String
    Get
        Return txtLastName.Text
    End Get
    Set(ByVal Value As String)
        txtLastName.Text = Value
    End Set
End Property
