Hi all, I have a serializable class 'A', which holds an arraylist. I add an instance of serializable class 'B' to this arraylist, then attempt to serialize class A using binary formatter, but at that point it dies. I've run it through the debugger and it just stops at the serialization...

Hi, I have a CommsManager object in my application which manages network communications, I want to create a new instance of this when the application starts, then persist the object so I can access its methods anywhere in the application.. I think this is kind of like how a session in asp.net...

Hi, I have two applications, one is a server and one is a client. upon recieving data the server sends a serialized "Request" (I know this is teh wrong way around but im only prototying anyway) object to the client, but when I try to deserialize the object on the client side I get...

hehe ;)

thanks chiph, I guess it wouldn't hurt to give it a go :)

Palbano, Thanks for your reply. I know how to do it technically, but the CartItemCollection itself just contains instances of CartItem class, and I don't believe datagrid will automatically read the public variables of CartItem and print to the datagrid. So if I had a method called...

Thanks chiph for explaining the inner workings for the model, that cleared up a few things, and Thanks palbano - I think I'll go with the MVC pattern as i've used this in a previous Java project.

Hi all, Say I had a CartItem class which represented a single cart item, and a CartItemCollection class which contains (not sure if this is how its done) a arraylist of CartItem objects.. How do I bind this data to a datagrid? create a datagrid in the CartItemCollection and return it? or is...

When developing with ASP.NET I have business objects that contain the data access code aswell. So: Customer cust = new Customer(CustomerID);, the class itself looks up the info for the customer and populates its own variables. Shall I go with this approach for a desktop application?

Great, Thanks very much. I did actually try that earlier but I had it on the wizard, so it only displayed a list of servers, with msde not included, oh well. Thanks again, Matt.

Hi all, I usually develop web applications, but am delving into desktop application development with c#. Im a little stumped on the archtecture of a .net application, I've gone through the tutorials but they all seem to be a little overdone. Currently im doing this: I have a user interface...

Hi all, I've just installed MSDE on my system, I already has Sql Server 2000 running. I installed MSDE as instance name "msde" and have compname&msde service running, so it appears to be working. When I open query analyzer I can connect to this instance and run queries on it, however...

Ok, Got the server/client working well. Thanks for the help palbano & ChipH.

Thanks PalBano, I've got the socket stuff sorted, I think its things like how im listening for connections etc. When I start the server socket, I bind the port to the socket and call its Listen method, then I have a while(true) loop with MySocket.Accept with a callback method, is this correct...

Hi, Im trying to create a socket library which doesn't use TcpClient or TcpListener.. I've written the client, which seems to work fine. On the server side so far I have SocketServer and ClientHandler classes, when the server accepts a connection it passes the socket to a new instance of...

Seems logical, I'll go with that. Thanks again Dan.

Thanks for the advice Dan. I've just run into my next problem however, I need to store a UserID_FK for 'Added by' and one for 'Managed By'. Or maybe I should put this stuff in a many to one table relating to the User, I don't know..

Hi all, Im not unfamiliar with sql server 2k but this time I want to make sure I have 'proper' naming conventions in the database. So heres the scenario: I have a table called 'Users' which lets just say for now has a primary key column called 'UserID_PK'. I also have a table called...

Thanks very much for your comments all, I got a socket server going and a client to connect, but then decided I didn't need it in my application. Oh well, good learning experience. Thanks again.

Hmm..wasn't listed in the properties on my class browser, oh well. It works anyway. Thanks very much John.
