Thank you sir. The following is what I ended up using and it works great. SetStatus d = new SetStatus( (string myText) => { // Do some work }); this.Invoke(d, new object[] { _text });

You don't need to put a ByRef array in the header. You just need: Public Function Rating(ByVal iNPS As String) As String() Dim result As String() Select Case iNPS Case "1/2""" result = New String() {"150#", "300#"} . . . End Select Return result End Function A guide to posting questions on CodeProject[^] Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007, 2008

It looks like you are trying to parse the string? You can make a class that contains the information from the string: Public Class RmtInfo Private _width As Double Private _height As Double Private _wallThickness As Double Private _outerRadius As Double Public Sub New(size As String) Dim s As String() = size.Split(New Char() { "x"C, "/"C}) _width = Double.Parse(s(0).Trim()) _height = Double.Parse(s(1).Trim()) _wallThickness = Double.Parse(s(2).Trim()) / Double.Parse(s(3).Trim()) _outerRadius = _wallThickness * 2 End Sub Public ReadOnly Property Width As Double Get Return _width End Get End Property Public ReadOnly Property Height Get Return _height End Get End Property Public ReadOnly Property WallThickness Get Return _wallThickness End Get End Property Public ReadOnly Property OuterRadius Get Return _outerRadius End Get End Property End Class Example: Dim info As New RmtInfo("3 x 2 x 3/16") MessageBox.Show("The height is " + info.Height.ToString()) Despite everything, the person most likely to be fooling you next is yourself.
