Using Color As Optional Parameter In a function within a class

Question

How can I declare an optional color parameter in some function or sub, as if I do that in the normal way (I mean to give some default color for that optional parameter) as t

Answer 1

You could overload the method

''' 

''' requires two parameters
''' 
''' an integer
''' a color
''' 
Private Sub Test(a As Integer, c As Color)
    'Your function
End Sub

''' 

''' one parameter, uses default color of black
''' 
''' an integer
''' 
Private Sub Test(a As Integer)
    Test(a, Color.Black)
End Sub
