DB/Reporting :: VB Connect To Sql Server?
Sep 9, 2011
I'm new to VB, trying to learn how to connect to sql server. When running the code below I got this message from visual studio: 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

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.

I'm using Visual Basic 2008 Express Edition. What I have is an Access database that will have several tables. What I want to do is connect to the database, enter the name of a table in a text box and query that table. The code that I have now is: [Code] I'm not sure how to modify this code so that tablename = whatever I type in the text box.

I created an executable file of an application done in VB Express 2010 which connects to a Access 2010 database. When installling the executable file at one of the user's computer, the file is installed correctly, but it fail's when trying to connect to the database. It says that Microsoft Dataengine cannot open the database. The user's computer doesn't have Access installed, does it need to be installed? or can I install a framework or application to avoid installing Access at the user's computer?

I downloaded the free Visual Basic Express Edition to create an application that connects to a Mysql database. I searched for the connection string and found a bunch of different ones.I have no idea which one should I use with Visual Basic Express Edition. I have been using PHP, javascript and mysql for a couple of years, but I have never used Visual Basic and have everything to learn.

I want to make an application that runs on 3 client pc's. The application has to query his data from an SQL Server-database, which is running on my Small Business Server. After some google-searching, i think my server is ready, but I don't know how I can connect my vb.net application on my client pc, to my SQL Server on my server. Here is a screenshot of my Object Explorer from SQL Server:
I don't have any idea how I have to build up my connectionstring. The name of my server is SBS2008, and it is on the same network as my client pc.

I'm looking to connect to an existing ftp server, upload a file, wait while the server generates a report on it, and download that report back to the local machine in a vb.net 2.0 winforms project.Is there an existing FTP library that would be helpful to me for this? My task seems simple enough that I'd rather not get into the world of active vs. passive, sockets, etc.

Ok well so I decided to create an irc client and for like a hour or so I tried to fix this error why it won't connect to the IRC server. So I tried to connect using telnet, still couldn't, the reason was that I didn't had any NICKNAME because the server needs the user to have a nickname to connect to a server( I guess so. ) Here's my code, it just connects to server. But it won't as it shows [code] So if anyone knows how to fix it, or just give me some code to connect to irc and send receive data.

I have to develop a small application that will connect to a Linux server (scp on port 22), upload a file, and then execute the file. The first thing that came to mind was to call WinSCP from my app, but the initial connection will always prompt to accept the hostkey. When calling WinSCP from the commandline you can press a key to copy the hostkey to the clipboard, and then you can use it with the -hostkey switch to connect. Any thoughts on how I might do this in VB? It would have to look like this:
Attempt to connect via WinSCP
Copy hostkey to clipboard when prompted
Attempt to connect again using hostkey
I'm just not sure about #2. I would have to send a keystroke for the letter 'C' which causes the hostkey to be copied to the clipboard.

Greetings,I created a new db in the SERVER Manager to experiment with; however it has real data that I would not like to loose. When I tried to access the db from VB 2008 Express it would not connect. Finally I connected by rebooting and NOT opening SQL Management applet. Ever since I have connected in VB I have not been able to connect from SQLManagement. I have been battling cancer for the past serveral years and have forgotten many of my skills. Things change so fast and I'm way behind.
