Give it an XPath expression and it will return you the appropriate nodes. In your case, it will probably look like xmlDoc.SelectNodes("//nodeName[@key='keyValue'"); assuming the key value pairs are of the form <nodeName key="KeyValue value="Value> budidharma wrote: public bool SetValue(string key, string value) { // ITERATE THROUGH THE VALUES, FIND THE CORRECT NODE // IF NODE IS FOUND, MODIFY THE VALUE // IF NODE IS NOT FOUND, CREATE THE NEW VALUE return true; } To modify an existing node, get a reference to it using the above method. Then use the Attributes property and the indexer to get a reference to the attribute and then just set the Value[^] property to the desired value. You can use the CreateNode[^] method to create a new node. budidharma wrote: public ArrayList GetAllValues() { You can again use Sele

That would be better IMHO. I was more poking fun at casing Jared Parsons jaredp@beanseed.org http://spaces.msn.com/members/jaredp/

Finally just figured it out. I had to specifically set the datagridview datasource to a table index contained within the dataset. I was just setting it to the dataset.

Let me rephrase that. I work constantly with C#, and I've worked with SQL databases, just not both together. I have a very simple understanding of ADO.NET. I'm most interested in finding out the correct way to use "data sources" via the VS IDE's interface as connections to databases. I hope that makes sense. Thanks again.

You should take a look at the Composite Formatting article on MSDN. It shows you the ins and outs of the process. For your immediate satisfaction, though, try this: String.Format( "{0,-6} {1,-6} {2,-6}", 7, 3.14, 0.5 ); "we must lose precision to make significant statements about complex systems." -deKorvin on uncertainty -- modified at 19:58 Thursday 24th November, 2005

Alright, i just figured that out as well: foreach(string Key in HandCounter.keys) Console.WriteLine(Key + ": " + HandCounter[Key].ToString()); Very simple, jeez.

I probably don't know enough about your application to advise you, but I won't let that stop me. :) budidharma wrote: public BetAction[] GetPossibleActions(int Position); // Return an array of possible actions, given the game context, for the specified player. Do you have a Player class? Would that be a good idea, do you think? Also, who decides what the next BetAction will be? Maybe the logic for deciding should be in the Player class? If the logic varies, maybe have an IPlayer interface that can be implemented with various player strategy classes. Here's what the code might look like: public interface IPlayer { bool Bet(); event BetEventArgs BetPlaced; } Then somewhere else in your application: PlayerCollection players = new PlayerCollection(); players.Add(new ConservativePlayer("Harry")); players.Add(new AggressivePlayer("Joe")); players.Add(new ModeratePlayer("Sue")); // ... foreach(Player p in players) { if(!p.Bet()) { break; } } The break looks ugly, and I'm sure there are cleaner ways of doing it. In part my suggestion is just guessing at a solution, but what I'm trying to get it is that maybe you should consider delegating some of the responsibilities of the table class to other classes. By putting everything in the table class, you may wind up with a monolithic class (a "God") class that does everything. This isn't considered good design in many circles. Just a thought, and feel free to ignore it. :)

You can use a struct instead of a class if you dont need inheritance. xacc.ide-0.1-rc2 released! Download and screenshots

Before I answer, how many times does the last foreach loop? Does it loop twice, then give the nullexception? Or does it immediately give the nullexception on thefirst iteration?

Yes you can, using this as a property name and optionally using the IndexerNameAttribute to get it a name (for some languages like VB.NET have to refer to the indexer while C# doesn't) other than "Item": public class Hand { // ... [System.Runtime.CompilerServices.IndexerName("Card")] // Optional public Card this[int index] { get { return m_Hand[index]; } } // ... } This posting is provided "AS IS" with no warranties, and confers no rights.

The reason is that the methods or constructors would have the same signature and that, of course, isn't allowed for overloads. See the IL for a method defined using the params keyword in C#: .method public hidebysig instance void Foo(object[] objects) cil managed { .param [1] .custom instance void [mscorlib]System.ParamArrayAttribute::.ctor() = ( 01 00 00 00 ) // Code size 2 (0x2) .maxstack 8 IL_0000: nop IL_0001: ret } // end of method Test::Foo As you can see, the effect is achieved using an attribute but the parameter itself is just an object[] array.

Hand hand1 = new Hand(new Card[] { deck.TopCard, deck.TopCard, deck.TopCard });

I would check out the XmlTextReader class. Its a very low-profile, rapid, and generally forward-specific class that can blast through huge xml files in short order. Its VERY easy to use, and should solve your problem in a heartbeat. You can likewise use XmlTextWriter to reserialize your collection to similar xml, too. :)

Yes, S. Senthil Kumar already pointed that out. --- b { font-weight: normal; }

That's true (and very cool :cool:), but: 1) The object you want to copy must be Serializable 2) I think (not tested) that it's slower than the usual way of Clone Pompiedompiedom... ;) "..Commit yourself to quality from day one..it's better to do nothing at all than to do something badly.." -- Mark McCormick

Thanks! Works perfect! I followed your advice and added error checking to make sure the value is between 0 and NUMRANKS (and 0 AND NUMSUITS for suits). Thanks again!

static doesn't mean its constant. It could be set from the outside to another value. You should declare your variables like the following: public const int VALUE_HEART = 0;

I have recently written something similar to you Data Server, and it works as follows. In the main thread I spawn a new thread which just listens (using TcpListener) for incoming TCP connections. When a new connection arrives the TcpListener passes a Socket object on the way out of AcceptSocket. I pass this socket to a ThreadPool worker thread which will handle the rest of the communication for that connection, meanwhile the listener thread loops back and waits for another socket connection. That provides a straight-foward multithreaded server approach - the server can communicate with several clients at the same time with each conversation in isolation from the others. As far as the client goes, that should be just straight forward socket stuff using either Socket or TcpClient. It's gone midnight here and I'm going to bed, but if you'd like me to send some sample source code through drop me a line and I'll do it tomorrow. Rob Philpott.
