    Dim rectanglePen As New Pen(rectangleBrush)
    Dim g As Graphics = Me.CreateGraphics()
    g.DrawRectangle(rectanglePen, rectangle)

    B
    Dim rectangle As New Rectangle(10, 10, 450, 25)
    Dim rectangleBrush As New LinearGradientBrush(rectangle, Color.AliceBlue,

    Dim rectangleBrush As New LinearGradientBrush(rectangle, Color.AliceBlue,
    Color.CornflowerBlue, LinearGradientMode.ForwardDiagonal)
    Dim rectanglePen As New Pen(rectangleBrush)
    Dim g As Graphics = Me.CreateGraphics()
    g.DrawPolygon(rectanglePen, points)

    D

  6. Question: You are creating a custom exception class named ProductDoesNotExistException so that
    custom exception
    messages are displayed in a new application when the product specified by users is unavailable.
    This custom exception class will take the ProductID as an argument to its constructor and expose this
    value through the ProductID.
    You are now in the process of creating a method named UpdateProduct.
    This method will be used to generate and manage the ProductDoesNotExistException exception if the
    ProductID variable contains the value 0.
    You need to ensure that use the appropriate code for the UpdateProduct method.
    What should you do? -(VB-.Net)

    A
    Make use of the following code:
    Public Sub UpdateProduct()
    Try
    If ProductID = 0 Then
    Throw New ProductDoesNotExistException(ProductID)
    End If
    Catch ex As ProductDoesNotExistException
    MessageBox.Show("There is no Product" + ex.ProductID)
    End Try
    End Sub

    B
    Make use of the following code: .
    Public Sub UpdateProduct()
    Try
    If ProductID = 0 Then
    Throw New Exception("Invalid ProductID")
    End If
    Catch ex As ProductDoesNotExistException
    MessageBox.Show(ex.Message)
    End Try
    End Sub

    C
    Make use of the following code:
    Public Sub UpdateProduct()
    If ProductID = 0 Then
    Throw New ProductDoesNotExistException(ProductID)
    End If
    End Sub

    D
    Make use of the following code:
    Public Sub UpdateProduct()
    If ProductID = 0 Then
    Throw New Exception("Invalid ProductID")
    End If
    End Sub
