You can do it two ways: 1.
Dim ColorVar as System.Drawing.Color = Color.Blue
MsgBox(ColorVar.ToString)Which will display
Color[Blue]2.Dim ColorVar as System.Drawing.Color = Color.Blue
MsgBox(ColorVar.Name)Which will display
BlueHope this helps!
Trinity: Neo... nobody has ever done this before. Neo: That's why it's going to work.

This is what i am trying to do... 'Changes the Colour of the Form's BackGround Colour. Dim RandomValue As Integer Dim Upper, Lower As Integer Dim NewColour As Color Upper = ListBox1.Items.Count Lower = 0 RandomValue = CInt(Int(Upper - Lower + 0) * Rnd() + Lower) NewColour = ListBox1.Items(RandomValue) Me.BackColor = NewColour the listbox contains the following :- color.red color.blue color.black color.yellow

I think you might be better off using an
Ifstatement.

in what way....:confused: this is the line where the problem is NewColour = ListBox1.Items(RandomValue) that is why i need to find out how to convert from a string "color.blue" to the system.drawing.color type color.blue

What is the type of the variable NewColour? The ListBox item stores strings, so you should use string comparisons in your if statements. If NewColour="Color.Blue" System.Drawing.Color = Color.Blue and similarly for all other colors HTH

trying not to be too blunt, but if you look at the 2nd answer, you will find that i am NOT using "IF" statements. And the variable "newcolour" is of type color.

Same here... If you look at my answer, you will see I have told you that a Listbox stores "strings"... and not variables of any other type. If you need to be able to set color based on a selection from a list box, change the type of NewColour to string and use the IF statements. HTH
