I have recently written a few TCP Client/Server classes for an application. The main thing I am worried about is if the server class is built efficient enough; I don't have any previous experience with tcp networking so I need someone to give constructive criticism and feedback on the design. I'll explain the server design below.At the very bottom of my framework is a ServerClient class, which is pretty much a TCP client with some extra methods, properties, and events. Each ServerClient continiously read for packets, once one in received, they raise a packet received event... this will come in later on.
The actual server class is simple, it uses another thread to endlessly loop waiting for connections. When a connection is found, it converts the TCP Client into one of the above ServerClients then adds event handlers for the packet received and disconnected events. Finally, it stores the newly created ServerClient into a hashtable with all of the other people who are connected to the server.
When a packet is received by one of the ServerClients it is forwarded to the server(because the event handler was set when the connection was established) and then in turn forwarded onto the application with the sender's ID.Just a brief overview, I'm not attaching any code because I don't like doing that. If you want to see it then send me a PM. I'm just looking for constructive feedback on the design; will this system work, will it scale with a lot of users, and how do large servers handle so many clients at one time?
how F# is a language which allows you to approach problems in a different way than in C#/VB.NET, i.e. instead of "pushing bits around" you "chain together data transformations", and that how F# will "become like XML", something that you use in addition to your language of choice (C# or VB.NET) in order to solve certain problems in a more efficient way.This got me to thinking about the relationship of the .NET languages, here's how I understand them:C# and VB.NET are syntactically but not substantially different, i.e. a C# programmer would not learn VB.NET in order to "approach problems in a new way"however, a C# or VB.NET programmer would learn F# in order to "approach programming problems in a functional way"but what about IronPython and IronRuby? Chris mentioned that "F# learned a lot from Ruby and Python" so I would think that F# has a similar relationship to IronRuby/IronPython and C# has to VB.NET. However, a little googling around tells me that IronRuby and IronPython are both built on the DLR but F# is not.
How are the relationships between F#, IronRuby and IronPython to be best understood?
I tried to bring a previously done webform made in vb.net to an IronPython asp.net website with no luck. After seeing it didnt work, I tried to write the simplest codebehind vb.net webform to see if there was a problem with vb.net in an IronPython website and I got the following usual error "be sure that the defined class in this file matchs with the one in the attribute inherits and that it extends the right base page (page or control)" (sorry if the translation isnt the most accurate I get that message in spanish)but if I create a vb.net webform in the same website, with the sourcecode in the same file (with the vb.net code between script runat="server" tags in the same page) I get no problem. Do I have to configure something for both kind of sourcecode languages to run in such way in the same IronPython website, like configuring something in the webconfig file or is there some compatibility issue for doing that which can't be resolved?
View 2 RepliesI am struggling with this program which uses emgucv(an opencv wrapper for .net) for about 2 weeks. The problem is unfortunately not programming, but setting up emgucv in such a way that it works. I didn't manage to do so for vb.net so I tried doing it for ironpython(because I know python too). Emgucv seems to work perfectly when using ironpython, so I created a function that takes an image as an argument and analyses it in the way I want, returning another image with the results in it. The problem is I want to call this function, giving it the image argument(it could be a string containing the path) from within VB.net and become another string containing the result image as return. I later plan to package that project in a setup so I can redistribute it.

View 2 RepliesHow can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.
Here is some example code of what I mean:

I have an OCX that I wrote in VB6.I added it to the vb.net toolbox and can drag the control onto a form and use it in code without any problems and it works just fine.But I can't see the control's design-time properties. In VB6 there's a small window on the right where I can set the properties of a control. In VB.Net I can see the standard properties such as Location, size, name etc but none of the control's own properties.
Do I need to register msstkprp.dll or a property page or something ?

I am redesigning an application that I have previously written which accesses an SQL database, pulls records, creates an object hierarchy based on a bunch of custom classes that I created, and displays them in a TreeView control. When the user selects a node, a tabbed page displays the information about the object underlying the TreeNode selected.
I have since begun experimenting with Databinding to my Objects as I have recently redigned the objects to communicate directly with the datarow that each object is based on instead of storing the values in a private variable thus:
[Code]...
Allowing the databinding management objects to do the heavy lifting of getting the values, displaying them in the controls and writing new values as needed back to the objects (and thus the DataSet) i think is preferable. How can I accomplish this? I have added the Objects as datasources to the DataSources window, added the objects elements to the tabbed pages. How do I bind those controls to the item that is specified by selecting the TreeNode?
