NXOpen.net Read Expressions

NXOpen.net Read Expressions

(OP)
Hi, I'm using NX7.5 and Visual Studio 2010.  I'm trying to read the numerical value of an expression (e.g 20mm) and display this in a text box in my visual basic program.  This is the code I have so far which was created using the NX Journal feature.

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        'Load default values
        Dim workPart As Part = theSession.Parts.Work
        Dim displayPart As Part = theSession.Parts.Display
        Dim markId1 As Session.UndoMarkId
        markId1 = theSession.SetUndoMark(Session.MarkVisibility.Visible, "Expression")
        Dim expression1 As Expression = CType(workPart.Expressions.FindObject("dblRawMaterialWidth"), Expression)



This is finding a dimension which I have called 'dblRawMaterialWidth' but I now want to read the value of this and display it in a text box on my form.  Any ideas?

Many Thanks,
Ben

Eventually got there after many hours!

Just needed this simple line:

txtChangeMaterialWidth.Text = expression1.Value.ToString

Where txtchangematerialwidth is the name of the text box
