TCP / IP Server - Remote Connection Fails To Connect
Mar 27, 2009
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)

Rather than use an Entry name of an existing VPN connection, is it possible to connect to a remote network by creating a temporary connection on the fly by using the remote IP/Host name, username and password?

Scenario: I want to develop an application.The application should be able to connect to my remote server and download data to the local disk , while downloading it should check for new files and only download the new ones simultaneously creating the required(new) folders. What am i doing?: The app first checks for internet connection , if available pings the server to check if the server is active.Then it has to download the new files.
Problem: I have no idea how to compare the files in the server with the ones in the local disk.How to download only the new files from the server to the local disk? What am thinking?: If i can create the exact folder structure(hierarchy) in the local disk as it is in the server...than i can download the new files accordingly to folders by maintaining some index file in both server and local disk.

I need to read a command from a .html file. To do this I use:[code]My application constantly loops to check the .html file for commands. I need it to do this, even if the internet is off. Obviously, it wont read commands if its off.. I just need it to resume reading when it comes back on WITHOUT crashing my application.Any code to ignore timeouts so where my application will still TRY to read and not crash.

I'm developing a online document management application for my client using the following technologies
Front End - VB.Net 2010 (Windows Forms)
Back End - SQL Server 2008 R2 Express (FILESTREAM enabled to level 3)
I wanted to store the files (*.pdf, *.doc, *.exe, .) using the FILESTREAM feature in SQL Server 2008 R2.I prefer FILESTREAM because sometimes the file size exceeds 2GB.I'm able to save and retrieve file with FILESTREAM (using Windows Authentication/Integrated Security).But my client wants to save or retrieve the file from different PC.So I'm in need of accessing the FILESTREAM BLOB from remote systems.

I built a window's app in VB. The app is made to be used worldwide. The app works fine when it is installed on a computer using the same network than the local machine hosting the sql database. The problem actually, is that, when the app is installed on a computer using a diferent network, the connection fails.

I have built a client-server VB.net inventory application for our company which connects to our Server machine running on Windows XP. We have 6 client machines running also on Windows XP that connects to the Server's database. Now, my problem is, "How do i connect a client machine running on Windows Vista to our Server running on Windows XP wirelessly?"
- Is there something I have to alter on the SQL Server Surface Area Configuration?
-Or do I have to change the 'Connection String' on my software application so as to properly connect to the Server from a Vista mahine? If then, how?
This is the error its throwing:"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)"

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.

I am a ASP Classic Programmer, professionally for a little over a year, I have developed some rather nice sites, including the one in my signature (Still a work in progress).
I have been forced to use ASP.NET (VB) for a FileUpload control, as it offers a self controlled way of creating Thumbnails, without the use of 3rd party controls, which is great, as my hosting server does not allow for 3rd party installs on their servers.
So.
The code below is what I have so far for connecting to the database and displaying a record is the "cookie" exist on the users computer.
Unfortunantly, this is not working, and to be honest with you, their is not a whole lot of resources available to show how to do this correctly.
So I am stuck with a lot of post and hoping that someone can actually assist me with this and tell me what I am doing wrong and maybe correct my code.
I am getting an error about the "Connection is closed"
If you want to re-write my code, I prefer something simple and basic, as the only thing that I am doing to checking rather the user is logged in, and if so, display a record from the database. I am NOT in the need for the DataGrid, so please do not suggest it, as I am only needing to check this one thing.
I would like to also add, that I have successfully contect to my database with the FileUpload control and save file names of the images uploaded, so I know that my connection string is done properly> But, for some reason the "SELECT" statement is causing a HUGE issue. (It was easier to insert, than to select, I am not use to that)

I am trying to build a user control that will do exactly what the SQL 2005 Connect to Server interface do, eventually create a connection string and store in a app.config file. It should allow user to select server type, server name, authentication, user name and password. It should also automatically load available servers and domain login by default.

I am connecting to a data stream that pushes data continuously and when I tried to set up a network stream I just could not connect and kept getting the 'not found' error. I used the httpwebrequest with webrequest.keepalive = true and started to consume the data by reading into a buffer and then appending to a stringbuilder. Once the stringbuilder reaches max size I flush it to a text file. The problem is that I get disconnected from the data stream because I am not reading the data fast enough. I need to keep the connection open and read the data while ensuring data gets stored in text files. If I use method "CONNECT" it does not connect to the stream.
While (True)
webrequest = DirectCast(Net.WebRequest.Create(url), HttpWebRequest)
webrequest.Credentials = New System.Net.NetworkCredential(username, password)
webrequest.Method = "GET"
[code]....
should I increase the buffer size and if so what is the max? that would mean I can read more data at a time and keep up with incoming push. Disparate here.
ACtually also I noticed that it gets stuck on this line
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
and then eventually I get disconnected.
