invalid cast exception, storing colordialog value in textbox

why do i get an error here?

TextBox1.Text = TextBox1.Text & Str(ColorDialog1.Color)

Answer 1

Try:

TextBox1.Text = TextBox1.Text & Str(ColorDialog1.Color.ToString())

Color is a type that stores information about a color, so you have to call ToString() to convert the value to a string.
