I learn how to make a simple client server chat on c#.
I did a small project and i really need to host the server side code on some server that support c# ,on my local machine it works fine.
Please,
How can i do this?whats my options?
You will need an iis server aka windows server. İf you don't want to physically host Azure is a good option if not there are many VM providers of Windows servers

Scenario: I have a small POS system running in a brick-and-mortar store. The software is running in Windows machines with SQL Server 2008 - 2012 (it varies). There are Android tablets that need to connect to the server in someway to get the data inside SQL Server.
My plan right now is to create some REST Web services using NancyFx and host them as a Windows Service inside the Windows machines. Then the Android tablets will need to connect to the server via HTTP in order to consume the REST API.
I have a problem (perhaps more than one): the network in the brick-and-mortar store is not that reliable and the Wi-Fi signal might decrease for whatever reason.
Question: Is there a way to automatically find the IP or machine name of the server (the one with the REST API) even if these properties change for some reason (unknown network issues or so)?
Yes, the server and the tablets are going to be on the same local network.
it's more of a network problem than programming issue. you must have a DHCP server installed in your LAN. use that to assign an IP to the server with a fixed lease. that way you fix the address of server. clients should preferably connect to that server using its name. since it's a Windows network, name would resolve to the ip address.
that is the simplest solution i can think of
I have to create a Lync 2010 bot. The initial idea that I pitched for the development purposes was to create the application on my own laptop and add the application as a trusted application endpoint to the production lync server. In that way I can develop and test the bot on my machine.
But, this idea was not highly encouraged by Microsoft themselves and they recommended to create a development lab environment to develop the application. I have done my fair share of research and have come to conclusion of adding 2 VMs -
1) 1st VM will serve as the AD server. My question is, what all things/roles should be added to this server like DHCP, DNS, IIS etc.?
2) 2nd will be Lync Server. Here I will create the connection with the AD server. Again, how will the connection be done? What extra roles should this server fulfill?
3) My laptop will act as the application server and I will add my laptop and the application as an application endpoint to the Lync server. Can I create all the three things on a single VM and not worry about multiple VMs?
4) Do I need an exchange server? If yes then why?
Any help is appreciated. Thanks.
I have a client-server application written in c#. I am hoping someone can give some direction on where to look in order to set it up where a user could connect to the server from their workstation, most likely through http but that's not a requirement, and download the client. The mechanism would need the following features:
Check for updates on client startup and automatically apply them.
Allow multiple clients (connected to different servers) to download on the same machine
Client can be downloaded by a non-local admin
Possibly install any prerequisites needed on the workstation
I currently use ClickOnce but it isn't quite working out. Currently the server sits in IIS and uses WCF services.
I am working on windows forms application using c#.net. i have developed an application(3-tier) that uses sql database as backend. i need to deploy the database on server and my app. on client machine. but how could my application communicate with database on server. please guide me.
you need a connection string that works fine during development. On your development machine if the application is connecting fine to the database server, chances are that on your client machine, it would work as well. Sometimes, the problem occurs with the credentials that you use, that might work on the development machine but on the client it wont connect due to the lack of access rights. so you need to make sure that you give proper credentials to connect to the SQL server
You don't need to do any rocket science for this. All you need to do is on the client side use the proper connection string that can connect to a remotely installed SQL Server.
Use EntityFramework for your sql server connection for updating, inserting and deleting.
Use storedprocedures for the insert/update/delete functions.
I downloaded the silverlight 4 socket application from the book "Pro silverlight 4 with c#" which is basically just a silverlight socket client and server application. The server is a console application and the client is a silverlight web applcation.
I can run the server and client fine on ONE computer, it shows that its connected and so on, but when i tried connecting to the server on a different computer (Local Network), it wont connect. Any idea??? Eventually i want to put this on the internet and go live, not local. When i run using visual studio development server, it shows localhost and port 1091, and i thoguth silverlight only uses port 5200 somthing.
Silverlight applications are only allowed to connect back to the site it was loaded from by default, much like Java and Flash does. If you need to communicate with another server, that server needs to explicitly allow it by running a policy service listening to port 943, or by serving a policy file over HTTP port 80. See http://msdn.microsoft.com/en-us/library/cc645032(VS.95).aspx for the full details on how to implement this.
Have you added policy file to you "C:\inetpub\wwwroot"?
I used example from "Pro silverlight 3 with c#" and its work from internet and local.
I added policy file to "C:\inetpub\wwwroot", where my silverlight website was published and everything works fine.
Note that website published in the same machine where server application runs.
Hope this will help you.
