Jan 13, 2010

2) Can I configure DB on my home PC ( no matter where client runs throughout the world if should refer the DB on my machine)

3) For Server - How to read the Users(Name and IP) from domain(AD) as well as on LAN.

Creating A Server Client Application

Jan 21, 2011

First of all, I want to say sorry if this is not a correct forum. I have built several standalone applications up until now. But now I need to create a server client application, the only database is on the server. The application itself is installed on all the client computers but not all of them are granted the same level of access to the database.

Creating Crystal Reports For VS 2005 For A Client Server Application

Jun 5, 2011

how to create Crystal Reports for Visual Studio 2005 for a Client Server application? The problem I faced is that when I created Crystal Reports for Visual Studio 2005 where the Crystal Report is displayed in the client application it does not get refreshed with data entered. It only displays data that was entered during the time of development. I think this is probably because the database path changes when deployed in a new environment while the Crystal report keeps referring to the database location at development time.

Client Server Windows Application

Oct 28, 2009

I have developed 2-3 standalone windows application using VS2008(vb.net) + Sql server (2008,2005) and quite comfortable with stand alone windows application. Now i am trying to make a windows app which will share a server database on LAN. I googled alot about this but still no success. So i decided to make that as stand alone app and i just changes the connection string to use remote server database. Everything is working fine still. All the insert, update and delete query are same as stand alone n me not getting any problem while testing through one more remote client system. But while googling i heard abt "CONCURRENCY" control.So please guide me is anything wll b wrong in future wid my this application when i will deploy this to my users? What about locks and how can i implement this to my Insert, update and delete queries to control concurrency and maintain integrity ?Please guide me step by step becoz i m new be to client/server application.

Server/Client - Basic Tcp Server/client Application

Mar 30, 2009

I've basically made a basic tcp server/client application. The thing is that I'm behind a router and so will be the other people that use my clients. I've had to use port-forwarding or the software "rinetd"to run quite a few applications online.

Let me explain: I'm on a lan network that connects to the internet. Whenever I want to host a server - for instance a basic ftp or http server. If I give my external IP to anyone, they won't be able to access my server. Even if I portforward, it doesnt work. I have to use rinetd here. For other applications, portforwarding works. I'm not sure how these things work at all.

Anyway, my issue now is that I have created this server/client application. I'm having serious doubts that if I run the server, I'll have to either a) portforward or use rinetd to get people to connect to my server. IF I need to portforward, that's fine. However, using rinetd would really suck... My 2nd concern is as follows: IF the person running the client is in a similar situation as me (i.e he's on a lan that has a router which connects to the net), will he have to portforward or use rinetd as well? If he portforwards that's fine. But I don't think I could get people to use rinetd.... Also, if there are more than 1 person on a lan trying to connect to my server, there is a big problem when they try to portforward: they will only be able to allocate one of their internal ip to that port, and the others won't be able to connect, right? How does this work? I mean, I use many softwares like msn/skype/(some games)/firefox that do not need portforwarding/rinetd. Yet they work. My housemates(other people on the lan) use the same softwares, and it works fine. There's no clash/probs watsoever How come these run fine?

Anyway, back to my issues. Given I have no knowledge about how the above work, I was wondering whether there was a way to host a vb .net server application on an external website (external to my house) so that I might *avoid* the above mentioned problems, and to what extent that would be a sound solution.

VS 2008 : Creating Own DataReader Like TCP Client/Server?

Jun 2, 2010

I'm not even sure where to start. I would like to create something like the ADO DataReader but that works in a TCP Client/Server scenario.Basically, in the TCP Client, I want to be able to call a certain command in the TCP Server which will return a DataReader like object, which I can then iterate through such as:

while dr.Read from the client. In each loop, I would parse out the various fields as in a normal DataReader.The reason I want to do this is to gain the inherent efficiency of the DataReader object since it doesn't first load ALL of the data. To my understanding, the typical TCP Client/Server setup using streams, would first load all of the data on the server, then transport ALL of that data to the client for processing. I want to avoid that, and just stream the data as the client requests through the Read() command which means the connection will remain open to the server while the Read() command is being issued by the client, or until explicitly closed by the client.

Oct 22, 2009

Im thinking of making a really user friendly tcp drag and drop tcpclient/server like winsock.

How would i create this for my toolbox, but use sockets with this item. or can it be as flexible as socket?

How would i do this? Would i need to add more or create a brand new socket with my mini drag n drop Client/Server Ex: MySuperEasyClient.ASCII.EncryptData.SendData(textbox.text)

ps: What would this be called? TCPClient/Server or UDP?

Client Needs To Have Sql Server On His Machine If Application Uses Sql Server?

Jul 16, 2009

I am creating small application (desktop search engine) which uses sql server as back end. Sql server is used to store huge data using indexing (for quick search). Is it necessary that client should have sql server on his machine to run the application? I don't want to install sql server on client's machine, because my application is just a small utility.Is there any other way so that I can store huge data using indexing?

Sql Server - Join Tables Based On A Column Without Creating Records For Every Combination

Mar 20, 2012

I have two tables as follows:

Customer | Product
------------------
A | Car
A | Bike
A | Boat

[Code].....

If I use a normal JOIN then I get a list of friends for every separate product. I just want the two lists once.

The output lists with '-' need not be table cells, they can be <ul>s.

How can I achieve this? I would like to bind to ASP.net GridView. Should I try to do it all in one query, or use multiple queries and somehow add them both to the same Grid?

Each row actually forms part of a long report. Essentially each row of the report contains Customer ID, a bunch of other fields which match one-to-one with Customer ID, then the two lists for each Customer ID I described. Perhaps I can use a separate query for each list, then manually add each list to the grid on RowDataBound or similar?

.net - Port Sqlite Application To A Server/client Application?

Jun 4, 2012

I have wrote an Application for a organisation and they had let the app run in their lan using Samba, it worked perfect. Now they want to work over the internet.The Problem is that I have written this app with Sqlite, that means its currently working so:They have a exe and the sqlite dll and the sqlite database on their samba server and they connected a network drive on their windows pc to run it. So that means every pc is writing over samba to the sqlite database.

I tried it over the internet, but like i thought sqlite is a local database and its very slow, even if the ping is under 50ms. I could create a tcp server, that handles all and writes all to the sqlite database, but I have already written around 20.000 code lines for the project, so that would be not the best option for the lazy me. I have used only one sqlite class in my client for querieng, so I thought that it could work without much work, if i would replace the sqlite database adapter with the mysql database adapter, since sqlite has nearly the same syntax then mysql.

VS 2008 TCP Server / Client - Client To Send The Server 4 Numbers - Depending On The User's Choice

May 9, 2009

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
