How to get a form's property value from a class?in another project, same solution). Here is the form's property: Private booIsInsert As Boolean = False Public Property IsInsert() As Boolean Get Return booIsInsert End Get Set(ByVal Value As Boolean) booIsInsert = Value End Set End Property Here is the class's function that needs the property value: Public Shared Sub FormDataChanged(ByVal sender As System.Object) Dim frmParent As Form frmParent = sender.ParentForm If Not frmParent.IsInsert Then 'SYNTAX ERROR line Dim ctl As Control ctl = CType(frmParent.Controls.Item("btnUpdate"), Control) Call FrameButtonPaintFlat(frmParent, CType(ctl, Control)) 'green frame around button End If Syntax error message: "IsInsert is not a member of System.Windows.Forms.Form" I understand the error, but is there *any* way to reference the frmParent instance and get the IsInsert property value? Or some other approach? Thanks in advance. Dean S You probably need to add a reference to
the project containing the class in which you want to access that form's property. (Did you get that?) To be clearer (I hope), an example: 1) Project 1, has Form1 with property IsInsert. 2) Project 2, has Class1 that wants to access Form1's property IsInsert. Open Project2's properties and click on References. THen click on Add. Choose the Projects tab, and select Project1. Then on the bottom of the screen, where it has Imported Namespaces, find Project1 in the list and check it (you'll have to click it twice). Not Project1.My or Project1.My.Resources, just Project1. *Now* you should be able to access Form1.IsInsert. Good luck.

The form should pass whatever information it needs to the class so the class can perform its task. Can you explain more what you're doing? If you really need to do this I'm presuming Robin's answer won't help because the project with the form already has a reference to the project with the class, so you can reference the other way. But what you can do is define an interface in the project with the class and have the form implement that interface. Michael If you want project1 to reference something in project2,
you must add a reference to project1, even if project2 has a reference to project1. It's project-specific, and project1 doesn't know about project2's reference to project1. Did I use the word project in there enough times? ;-) Robin S. -------------------- Show quoteHide quote "Michael C" <nospam@nospam.com> wrote in message news:eESGykeDHHA.952@TK2MSFTNGP03.phx.gbl... > "Dean Slindee" <slin***@charter.net> wrote in message > news:2aO8h.263$MY7.29@newsfe06.lga... >>I have a form whose Property value I need to get at from a class >>(contained in another project, same solution). > > I'd suggest you're doing something wrong.

My mistake. Thanks for clarifying. Robin S. Dean,
I have almost the same idea as Michael, even more, it seems that you want to give the property at a certain moment to the class. I think that than a method is more sufficient because than the given data can be processed.
