Witam,
dlaczego w poni¿szym otrzymujê b³±d:

System.InvalidCastException: Nie mo¿na rzutowaæ obiektu typu 'System.Windows.Forms.CheckBox' na typ 'statmbp.checkboxyn'.

W kodzie designera zmieniam t± linijkê:
Friend WithEvents CheckBox1 As System.Windows.Forms.CheckBox
na
Friend WithEvents CheckBox1 As CheckboxYN

W momencie startu programu otrzymujê powy¿szy b³±d.

Public Class CheckboxYN
    Inherits System.Windows.Forms.CheckBox
    Public Property YesNo As String
        Get
            If Me.checked Then
                Return "Y"
            Else
                Return "N"
            End If
        End Get
        Set(value As String)
            If Me.Checked Then
                Me.Checked = True
            Else
                Me.Checked = False
            End If
        End Set
    End Property
End Class

Pozdrawiam,
Grzegorz.
