Accessing calling application from a .dll

Question

I have a vb.net application that accesses a vb.net .dll file. That .dll file works fine and does what it needs to do. But what I am wondering is it possible for that .dll to call methods on the main application directly? Right now I have the .dll accessing another .dll to do some logging and whatnot but it would be much easier for me if the first .dll could do what it needed to do and then just call some methods on the application that called it. Is this possible?

I found this article from the MSDN help system for Visual Studio. It might help you some. ms-help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.1033/dnvbpj01/html/pc0108.htm

That is what I was hoping. Im just trying to figure out how to reference the parent application. I keep trying to hard code it somehow with the name of the application or whatnot but since the .dll doesnt have any idea what that is it wont compile. I am trying to find a command on the .dll that will reference the application that called it but haven't had any luck yet.

You'll have to do some experimenting. The library contains class definitions (among other things). When you create and object that uses the library classes. In essence the object becomes a child of the parent. So a reference to the parent is all that is needed and permission to access the method within the parent class.
