View 3 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.

View 1 RepliesMake Client Server Without Installing Sql Server?
Nov 6, 2009I have an application in which i have a database .mdf file in directory which i use a connection string to give a path of to access it, which means without installing sql server i can access database. Connection string below to access this database(.mdf) which placed in the directory.
dim con as sqlconnection = New SqlConnection("Data Source=.SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|Universal_data.mdf;user instance=true")
Now the question is that if i access this .mdf file without installing sql server, i also want to access to this .mdf file on other computer(client) after creating DSN or any other connectivity tool.
Let me know you that when i install sql server 2000 or 2005 i create SA user name and password which i use to create DSN on client computer and give SA username and password in the connection string that successfully works and client get access to sql server, connection string is below.
Dim serv = "MY-LAPTOP"
dim con as sqlconnection = new sqlconnection("Data Source=" & serv & ";Initial Catalog=clinic;Persist Security Info=True;User ID=sa")
I only need to know that my application access .mdf file without installing sql server works fine on a single computer, and i want to give access to this .mdf file on other clients without installing sql server on server computer (like i mentioned above paragraph) how will do it.....

Jul 16, 2009I 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).

Jan 8, 2010I have been struggling to find a solution for this problem.

I experimented by using asynchronous mode call backs etc. but it disconnects once connection is established and does not respond for further requests from the same client.

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])
