Hi Shal,

When you handle your optionform as a dialog form it becomes very easy.
You make a property (or just a public field) in your optionform

Private Sub BtnOptions_Click(ByVal sender As System.Object, ByVal e As

System.EventArgs) Handles BtnOptions.Click

Dim N As New Form2()

N.Showdialog
mycolor = N.myoptioncolor
N.dispose

End Sub

I hope this helps?

"Dim N As New Form1()"

Is the incorrect line, this creates a new instance of Form1 instead of
referencing the existing Form1 Instance..

You will need to pass a reference into Form2, either for the Instance of
Form1 you currently have or for the specific textbox on Form1 you wish to
change. (I'd go for the second option, as you can then use it with other
textboxes also.. reusable code..).

So in Form2, create a TextBoxToAlter Property (or some such).. then when you
create Form2, set the Form2.TextBoxToAlter = Me.TextBox1 (Assuming you're
starting Form2 from Form1)

Then in Form2, use Me.TextBoxToAlter.ForeColor = Color.Blue etc.....
