Bonnie,

Thank you for your quick reply. That is what I needed. I am going to be referencing projects from other solutions. Don't go to any trouble but if you think of this step to help with the dilemna of an old .dll I would appreciate it. I will look myself.

Thanks again,
Paul

>The "using" statement is simply a way to implement a shortcut in your code so that you don't have to say xyzproject.MyClass, you would simply say MyClass. But, in order for one project to recognize another, there's an additional step you have to do and that is to add a reference to the xyzproject. In the IDE, in the Solution Explorer, right-click on your project and choose "Add Reference" and click on the Projects tab. All the projects from the existing Solution will be displayed in the ListView. If you want a project from another Solution, simply click the Browse button and go find the .DLL. This will copy the .DLL into your bin\debug folder. The downside to grabbing a .DLL from another Solution like this is that when that .DLL changes, you are no longer referencing the changed .DLL (because you put a copy of the old one in your project). I think there's a way to overcome this, but off the top of my head, I don't remember what needs to be done (and I can't look it up right now).
