As it says on the tin, I need an example of a simple winforms peer to peer chat app in VB.Net 2005 as a basis for a works project I'm working on. I've scoured the net and found many C# versions, but time is a bit too limited to convert everything to VB. Does anyone know of any such example code or a link where I can get some pointers?

View 3 RepliesI am architecting a program that I need some help on. I need to have a "watcher" program that will sit on a server and monitor a SQL Server. At configured intervals, the watcher will run a query on the server and create a dataset of information I want to share to any clients that are listening. I am looking at WCF Peer channel but all I can see is peer to peer chat and most of the examples I have seen are partial examples. I have looked at the example program from Microsoft but I am still a bit confused. The listener programs will receive the dataset of values from the watcher and filter the data at the local level and display the data they need and display it to the end user. I don't know if a TCP client/server would be a better solution, but the dataset may contain up to 10,000 rows of data. From what I read the WCF Peer channel will transmit at 50 mbps and should handle this load. My other option is a server/client architecture using TCP spawning a new thread for each request. Does anyone have any good examples, or articles about WCF and VB that they can point me to?
View 2 RepliesThere are a lot of different generic collections available, so the wisdom in creating a new one may be questionable right from the start.However, I often find myself wanting the same features from my custom generic lists, but cannot quite find all of those features in an existing object; namely, I would like to have a generic collection which works like a List or Dictionary (much like the System.Collections. ObjectModel. Keyed Collection(Of TKey, TValue)), but also works like a BindingSource does when it is bound to an ADO object (that is, it supports full sorting and filtering as well as currency).A feature I almost never need however, is transactional adds (the BindingSource's ability to 'cancel add-new').Again, with so many existing collections out there, I should take a moment to go over the reasons why none of them quite meet my needs.There is the System. ComponentModel. BindingList(Of T) which would provide some of the functionality of a BindingSource, but has strict requirements about the type {T} implementing IComparable in order to support sorting, and does not provide filtering (it is not an IBindingListView).It also only maintains a base item list by index, so does not provide keyed access.We could use simple databinding with a custom list inheriting from System.Collections. ObjectModel. Keyed Collection(Of TKey, TValue) bound to a BindingSource, but again TValue would have to implement IComparable to support sorting and we would still not have filter support.So to get all the features I was after, I decided that the best thing would be to create a new generic collection object which implemented IList, IDictionary, IBindingList, and IBindingListView (along with a few others) and would be capable of serving as a simple list, or as a binding source while providing full sorting and filtering over any newable object type.
To that end, I've created the KeyedObjectModel which contains the KeyedBindingList(Of TKey, T) generic collection/binding source. This collection can be used as a typical list, or as a binding source (you do not need an additional BindingSource component between the collection and UI controls, although you could certainly have one).Various constructors are provided in order to initialize an instance of the collection as either an enhanced list-dictionary, or as a complete BindingSource.Any object that has a public constructor which takes no arguments can be used at type {T}, providing that the object has a property of type {TKey} which will contain unique values for each entity in a given collection.If the object implements System.ComponentModel.NotifyPropertyChanged then the collection will also bubble up property changes on the current item to the collection's CurrentItemChanged event.An implementation of IComparable on type {T} is irrelevant because sorting and filtering are performed on the property values of {T} based on the type of the specified property.The current design of KeyedBindingList(Of TKey, T) is in an 'alpha' stage.The class is mostly complete from a feature implementation standpoint, however, the code has not yet been optimized and the base collections of values, keys, and view are being maintianed in generic lists of their own, rather than raw arrays.However, even without performance tuning, the collection appears to be performing quite well, up to a few thousand entries, given the amount of flexibility and funcitonality it provides.At this stage, I would really love to get some peers to try using the compiled DLL and beat up the collection a bit.Once the code has been proven and optimized, I will publish it as an example.It is a fairly complex class though (currently made up of eleven or so partial classes) so I don't really want to post the code until it has been optimized.

I want to create a CHAT server?
View 4 RepliesI have google it but I couldn't find the answers. So basically I want to make a Client-Server chat. I just want to creating each server for the clients to entered the chat room with each different server, e.g: client 1 and client 2 entered chat server 1 (just a name of a room), client 3 and client 4 entered chat server 2 and so on. How I can do that?
View 5 Repliesi have wanted to create a TCP/IP Lan chat program in visual studio 2005. i have already created an interface for it but no codes yet. Attached are images of the client and the server.
View 3 RepliesTo summarize, my program uses a textbox to display the chatroom from a text file on the school network. When someone sends a message, it writes that message to the text box like so:My.Computer.FileSystem.WriteAllText(baseDir & room & ".txt", Message, True)
The baseDir is where the chat files are stored, and the room that the user is in can be altered by the user. created a scroll bar to use so when the chat room reaches a certain length of lines, you may use a scroll bar to view the whole chat. I realized that when someone sends a new message, the scroll bar then jumps back to the top of the text box. Is there any way to fix this, so that it will jump to the bottom each time someone types something new?
Dim lines As String() = IO.File.ReadAllLines(baseDir & room & ".txt")
Dim numLines As Integer = lines.Length
If numLines > 20 Then

View 2 RepliesI want to create a 3d graphics chat. (Think Imvu Not Single Life. I tried opensim, that's a virtual world, not what I'm looking for, plus would prefer to code my own, as I was needing to rewrite so much)This chat I would run between friends on my own server (no monies for server costs)
First I need to know if I am on the right track or not.
ie : need 3d graphics engine at base ? (Any opensource ones I could look at legally to learn from?) need instant group chat engine?(Any opensource ones I could look at legally to learn from?) need login forms, web browser/viewer to run graphical chat in? plus of course I would need a database of meshes and so on?
So first I need to know if I'm looking into the right areas, plus where to find up to date tutorials (ie links) the web is huge? (Oh and opinions from more experienced people.)
Furthermore can this all be coded in vb.net or do i need to code part in C# and add together, can that be done?
Plus I am using a trial version of ms visual studio 10, I am unable to purchase it when trial runs out and do not know what I can switch to then that is free an legal to use, to learn an create opensource projects.
