Why Isn't Server Accessible Outside Of Computer

Jun 5, 2012

I've created a Http Server in VB.net.I've used the same "template", I guess you could say, for every project requiring an Http Server (quite a few recently).The problem is, this one I'm working with now requires that the computers on the LAN be able to connect to it. I can access the server directly from my computer though using: [code]Now I get an error every time when it tries to apply the prefixes: I've checked all the ports that are listening and 8002 is still open...

VS 2008 Connection To Sql Server Failed (server/'localhost' Not Accessible)

Aug 18, 2009

I have simple code that connects to Sql database... (well it doesn't)

VB
Dim objConn As New SqlConnection("Server=localhost;uid=***;pwd=***;database=***")
objConn.Open()

ERROR MESSAGE: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)But looks like something is wrong with "localhost" thing. Any help? Where can I get name of (my) server?

Sql Server - Attached DB Is Not Accessible To Make Connection?

Feb 10, 2012

I created a DB using following code.

Dim conn As New SqlConnection("Server=.SQLExpress;Data Source=;Integrated Security=SSPI")
Dim cmd As New SqlCommand("", conn)
cmd.CommandText = "CREATE DATABASE MyDBTest22 ON ( FILENAME = 'D:dbTestATTTTTTT.mdf' ), ( FILENAME = 'D:dbTestATTTTTTT_log.ldf' ) FOR ATTACH"

[code]....

It ran without any error but when I opened SSMS, I could not see my file attached to the server. Also, I tried to make a connection, but it says file does not exist but when I tried to re-run the above code, it says File already exists.Something wrong with my way of doing it? I want to see it attached with the instance of my SQL Server Express 2005, using SSMS.

DB/Reporting :: Connect Database In Server From A Client Computer?

Feb 24, 2008

I wrote a program in VB2005. It is a program that is supposed to run in a client computer accessing an MS Access .mdb file stored in the server. The program itself is stored and run in the clients computer. I am not good in networking at all. The way I do it now is:

1. Have a directory made in the server to hold the MS Access .mdb file, and have the directory to be shared.

2. Have the same directory accessed and mapped in the client computer (say to Z:)

3. Then have the program in the client computer simply access the database as if it is in the same computer (as the directory already mapped into the client computer). In the VB 2005, this is done when we set the connection string of the database connection.

However, my user is complaining that by doing so, the database is basically exposed to the operator of the client computer (through the mapped directory), hence more vunerable for any bad intentions from persons who may have access to the client computer but not the server. He insists that he used to have a program that does exactly the same thing like my program, but the database is shielded in the server, where it cannot be seen in the client computer (I have other people who confirm that this can be done, though they can't tell me how, since they are not programmers themselves). Now, I have no idea on how to connect a database that way, and I don't even know where to start looking.

Get The Hardware Info Of Server (similar To Win32 For Individual Computer)?

Oct 25, 2008

Up to now, my programs are installed in individual computers, and I use the data collected using Win32 classes (such as bios, board, and processor) to lock my program to those computers to avoid piracy. However, I am currently preparing two programs that will be installed in servers and accessed by more client computers. My problem is that I once read some ways of doing the same thing with server (accessing the hardware info of the server), but I simply can't find it again in my archive. My idea is simply to lock the program to the hardware info of the server computer, so wherever the person runs the program, it will be first checked the server hardware info, if it matches, only then, it will run. My client server is Windows Server 2003, and I am programming with VB2k5.

Sockets - Check That If Another Computer In The Network Send Some String Data To The Listener Computer?

Mar 19, 2012

i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:

Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....

But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?

Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?

Developing A Computer Application Designed To Monitor The Network And CPU Statistics On A Computer?

Jan 29, 2009

I am developing a computer application designed to monitor the network and CPU statistics on a computer remotely. The monitored computer would have my program installed and the monitoring computer would display, in a form, the information being sent from the remote client.The application does not send any information regarding packets, user names, passwords, etc. It is solely meant for monitoring CPU performance and Network resources remotely.

What would be the best method to send this information over to my host machine?I am programing in Visual Studio 2008 on windows XP. The client machine is also XP. I know this sounds a little shady, but it is required for my little business (http://www.iquorum.net) to monitor what and when something happens on our machines when I and my employees are away.

VB - Desktop Computer With Cable Connection On Back Allows To Watch TV On Computer Using Windows Media Center

Jun 12, 2010

I have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans. I have no idea if this is possible or how I would even do it,

So I have three questions.
1: Is it possible?
2: How would I go about access the feed?
3: How would I send it over the network?

My original thought was doing it in Flash, but I'm not very good at Flash so I wanted to do it in VB.Net.
