Oct 28, 2009I 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.

May 9, 2009how 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])

View 6 RepliesServer/Client - Basic Tcp Server/client Application
Mar 30, 2009I'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.

Oct 16, 2010I need some pointers on which .NET technology to use for a project I'm working on. I'm building a "dashboard" digital signage WPF program that will display various things on a large monitor mounted high up in the ceiling of my office.What I need to be able to do is control certain aspects of this program from my desktop. For example, there will be a TV window in the application with signal being provided by a TV tuner on the mini-computer connected to the monitor in the ceiling. What I want to be able to do is make a remote control to be able to change the channel etc. I'm confused at what technology to use. I've read about remoting, WCF, and simple TCPclient classes but I'm confused at which one would be better. I'm thinking it may be better to use WCF because what I think I need to do is make a function that will change the channel and accept channel numbers, etc from the remote control program. Am I on the right path?

Oct 26, 2010We are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.

Jul 9, 2010I have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]
