Hi, Sorry for this late reply but I was on vacation these days. First, you have to make sure that generated classes are all defined with partial keyword. For example : // Auto-generated file public partial class DataClass { //... public partial class Email { //... } //... } Then, just add a Whatever.cs file to your project : // Custom file. This will never be modified when you regenerate your model. public partial class DataClass { //... public partial class Email { public override string ToString() { //... } } //... } You could also define an extension method for you Email class : just add an Extensions.cs file to your project and define an extension method to the Email class. public static class Extensions { public static string ToString(this Email email) { //... } } Hope this helps. Kindly.

IoC? I havn't practically used that pattern yet, but ain't that some kind of Facade/Controller pattern? But after what I see in replys, I guess that making folder in the solutions for keeping subsystems controlled, is a good idea, and may be the correct use depending on size of application? And add the using .Marketing or .Management in the classes, sounds like a nice trick instead of editing 10000 lines of code.

It depends on what is the job of controllers, your architecture is not the only possible, i post a fragment from wikipedia about architectures : Architecture description languages Architecture description languages (ADLs) are used to describe a Software Architecture. Several different ADLs have been developed by different organizations, including AADL (SAE standard), Wright (developed by Carnegie Mellon), Acme (developed by Carnegie Mellon), xADL (developed by UCI), Darwin (developed by Imperial College London), DAOP-ADL (developed by University of Málaga), and ByADL (University of L'Aquila, Italy). Common elements of an ADL are component, connector and configuration. Piccadilly Yum Yum

Happy to help, good luck! I must get a clever new signature for 2011.

Thanks for your suggestions, but it didn't quiet make my solution. I'm looking for an API with a DLL I can use for this purpose, I want to use the existing SNMP protocol with correct MIBs and OIDs to collect and find the mac address on a switch port which is already known. I have almost figured out at this time, how I locate a switch port based on a known mac address, but I want the opposite options if even possible? My last thoughs was read the FDB table mib request (which should return all mac address' and portnumber for each?), and sort them after the port number? But I stumbled on it, cuz it seems that it returns some wrong bits (which ain't representing the MAC address in HEX string). Any other suggestions, that could help me using the SNMP and mibs, collecting a mac address, on a KNOWN switch port?

Telnet is TCP Port 23, then use TcpClient. I prefer using TcpClient than Socket.

Following links will give you answer of your second question. http://msdn.microsoft.com/en-us/library/k5befhe3%28VS.80%29.aspx[^] http://todotnet.com/post/2005/10/11/Customize-the-Default-Web-Page-for-a-ClickOnce-Application.aspx[^] HTH Jinal Desai - LIVE Experience is mother of sage....

No, it's not. That's the point of the question. If you had more than one person hitting the service at the same time, one instance would get access to the serial port and the other would throw an exception that the port is busy. The question is how does your service code handle that little problem.

Thnx a lot. I still havn't got it working yet... I'm kinda affraid that its because the dataGridView is "coded" and not drag n' drop'ed... Its just annoying to start over with code who seems too work as they are, but just not when you want this new feature. Its one of my old partners who developed the code, which is why I ain't 100% confident with it yet. If you find an answer why my event ain't triggered, plz let me know (note that this win form has a TabControl and 3 TabPages).

Thank you, I'll study it and re-open the question if it wasn't enough:)

Ye I guess it might be, when you first explore the way they work, and figure tag functions :)
