I am struggling a lot with this code I am trying to get to work. I have successfully made a connection with the TcpClient object to two separate remote machines and transmitted data to them. Essentially, I'm trying to connect to Machine 1 on port 80 and send a GET request. Once I send the request I want to keep the connection alive so that the software on the other side can send me data when it is ready. How do I keep the connection open and read data in each time it is made available in the stream? I have tried and tried using NetworkStream.Read and BeginRead to no avail. The closest I have come was sleeping my thread every 30 seconds and then doing another GET request which is not needed. Here is the current code I have for reading from the stream. I know I need a loop in here somewhere:Note: RemoteSocket is my TcpClient object that is connected by this point
Dim serverStream As NetworkStream = RemoteSocket.GetStream()
rqst = "GET /Control/Clip_Forwarding_Stream?CameraName=" & URL_Encode(Name) & " HTTP/1.0" & vbCrLf & vbCrLf

Is there a way to make your webbrowser connect (or your computer ping) to a website via proxy server? (ex: 123.123.123.123 :: 12345)
Not a proxy like corpask, but an IP and port.

I have an internet available SQL Server 2008 R2 instance that is running normally. Clients connect over the internet from vs 2005 and 2010 desktop applications, without issue. My scan gun application can connect to the local instance (if I'm in my office) but not to the internet instance from my Windows Mobile 5.0 scanning device. Connect string = user id=[Code]. This connection string works fine for the desktop apps. It's not a port issue, I have all the correct ports open.
View 10 RepliesI have a very irritating problem with connecting to SQL Server/Database. I've created a windows form and connected it to the database on my server (connection string: "Data Source=KARIMOV-PC;Initial Catalog=ApplicationForm;Integrated Security=True")... it works well and without any problems!!But I when I tried to connect my application to the database through internet with connection string "Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=ApplicationForm;User ID=KARIMOV-PC\KARIMOV (My computer name and windows authentication ID);Password=;", the "USUAL" message has appeared to me saying."A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)".
I really really need to understand why my own server "KARIMOV-PC" doesn't work as a remote SQL Server although the SQL Remote Connections and SQL Browser r enabled and running? And Why .\SQLEXPRESS is the more needed/required although I log in to SQL with Windows Authentication, but not SQL Authentication??

I've came across a little problem with my tcp / ip server. My client can connect to it with 127.0.0.1 ( localhost ), and 192.168.0.X, but every remote connection fails to connect.
Here's the connection rituals:
Server
listener = New System.Net.Sockets.TcpListener(System.Net.IPAddress.Any, Port)
listener.Start()
listenThread = New System.Threading.Thread(AddressOf doListen)
listenThread.IsBackground = True
listenThread.Start()
Client
client = New System.Net.Sockets.TcpClient(IP, Port)
client.GetStream.BeginRead(readBuffer, 0, BYTES_TO_READ, AddressOf DoRead, Nothing)
I have a client that wants to connect to his MySQL database using Dial-up/Modem connection. All i know is a phone number. I will be using VB.NET 2005 for this project. We also have a LAN Connection setup to other computer, but some of this computer only uses Dial-up to connect. The LAN connection works fine because i can just use the Local IP to create a connection string.But my problem is how do i get to connect to a remote server using a Dial-up? I know building a connection string require an IP to connect. Do i need to get the IP after a dial-up connection is connected or to i need to use different approach? I have a server and i have 10+ clients, the server has a T1 connection + a dial-up modem installed also.I created a POS system to all the clients, Some clients uses dial-up some uses LAN. What the server do is all the records of the clients POS will be sync to one database on the server in one table. If i'm in the server and and i selected a station/client and click SYNC button all the records on that client will be sync to the server.
View 2 RepliesI am currently porting (well really totally re-writing) a project to run on WM6 devices. I need to initiate a GPRS data connection (or any internet data connection really, shouldn't matter if its GSM or CDMA) before I can get the data I need (actually sync. a database over the cell network - Sybase via Mobilink) because right now its basically saying I have no network connection when I make the call to sync the db.
If I open Internet Explorer on the device, it initiates the data connection, and I can then go back into my program and get the data no problem. This isn't an acceptable solution however.
How can I initiate the internet data connection?
