i am having alot of trouble finding the source code to establish a connection to a remote sql server ( at my university) for vb. All i have is the IP adress and the username and password to the database. I tried coding it with a sqlconnection, sqlreader and a command to execute the statement with no luck.
View 2 RepliesI want to understand the concept of connecting to a remote PC or server. I'm working on an app that will connect to a remote server. Read a value from a registry key and then display the results in a text box. It will also connect and search for a specific log file on a server. I understand how to read the files. I'm just not sure how to connect to a machine remotely if I have valid credentials. There seems to be sever ways to accomplish this. I want the most efficient way using vb2008.
View 3 RepliesI'm been learning about connection strina I have been able to succesfully connect to a sql database stored locally on my Pc.The next logical step would be to connect to a database stored on a remote server. My question is does anyone of a sql database ( or any other type of database ) which can be openly accessed by the general public. Does anyone know if a web hosting service would allow me to remotely connect to a sql database ? Could I for instance upload my database onto a web hosting service and try connect to a remote database that way
View 1 RepliesI have developed a frontend app using VB 2010 which is to connect to a remote MySQL server. My server has an internal IP address of 202.56.20.72 and an internal IP address of 192.168.20.44.
When I use the internal IP in my connection string and connect over LAN, the whole thing works fine. But when i changed the IP to the external address and tried to connect to the server over the internet, I get an error something like 'Failed to connect to MySQL server for user 'user'@'localhost', [using Password=NO]. This means that for some reason, it is not connecting to the server at all.
My.Settings.ConnectString = "Data Source=123.132.123.123,3306;
Network Library=DBMSSOCN;
Initial Catalog=Authorities;
User ID=AppUser;
Password=mypassword;"
i need to know what will it take for me to access, insert, update and delete data to a database on a remote SQL Server. I already made some configurations to the SQL Server 2005 that I want to access by following the steps coming from this link -> [URL]. But somehow I am still getting an error. My primary concern is "What connection string should I use on my client VB.NET application to connect to the remote SQL Server?" Since I will be connecting to the SQL Server via Internet and not by LAN, I am wondering which IP Address and Port am i going to put on the 'connection string'? How can i get my 'TRUE' Ip address? Or is there any other way to go through with this? It will be very helpful if you could share your insights and knowledge. Here's my sample connection string:

View 1 RepliesI've been using several search terms, but couldn't find the answer. Maybe it is there and I havent looked good enough. I have a small program to which people can login to. All login info is stored in a simple html page. I manually add the info to that page.
I want to make a 2nd program, that is able to see who is currently logged in into the program. If I click Refresh, I want to let a list fill with all the Usernames currently logged in.
I don't have a clue where to start. I'm guessing making a remote connection between two IP adresses, but if the client programs dont know the IP to connect to, and the host program doesnt know the IP's belonging to the Usernames, Im lost.

good mornign here again =D having a problem with connecting to a remote database via adhoc we are using a windows 7 ultimate 32bit OS platform =D
here is the connection message im encountering
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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
i have already enable the the Remote Connection enabling the both TCP/IP and name Pipes and its server authentication of our both msSQL server 2005 is SQL SERVER AND WINDOWS AUTHENTICATION MODE
and also i put a check in Allow Remote Connections to this Server...both our laptops...
but still encountering the problem... the default gateway of our adhoc is 192.168.137.1

I am currently developing in Visual Studio 2008 (Visual Basic) and I have no problem reading, editing, saving, etc. to a 2007 Access database that is stored locally using the following code:
Dim NotifyDS As New DataSet()
Dim NotifyCon As New OleDb.OleDbConnection
NotifyCon.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|DataSettings.accdb"
NotifyCon.Open()
Ultimately I am going to be installing this program in my office on multiple computers, but would only like to have one "server" program where the database is installed. All of the other computers will have access to this one database over the LAN. For some reason I am unable to access this remote database file over my LAN. I have tried all sorts of things (including a username and password for the server computer),

I need to create a application that will allow me to connect to remote computers and find out the os like w2k or xp so i can run the right scripts for that os.be able to input add an ip or computer name and pass it all scripts like bat, vba and psexec.
I would like to be able to put all util files and scripts in a single dir and have the selected from 2 or 3 differant dropboxs ie... bat's in one droplist and vba's in an other dropbox ect...
have preselected buttons to perform basic function:
1. who is logged on
2. what OS and service pack info
3. connect with netmeeting or remote desk top
4. run a remote command on remote desktop IE.. open with my user account a CMD, Control Panel, Explorer, Explore Network Connections.
have the app ping the pc first to verify connectivity, then execute the script or bat.

So I moved the code to an ASP.Net web app, which is impersonating a service account through the Impersonate section of web.config. The account I am impersonating does not have admin rights on any of the workstations so I put in a username/password into the constructor for the computer entry like so:
Dim deComputer As New DirectoryEntry("WinNT://" + Computername + ",computer", username, password).The username is that of a domain account which has local admin rights on every workstation. If I look at the Username property of the resulting deComputer object I can see that the username matches what I entered.Also if I enter in an invalid password it throws an error, so it is authenticating in some fashion.
However if I now try and add or remove a user from a remote workstation I get a general access denied error. If I add the service account that ASP.Net is using as a local admin on that workstation it will add and remove no problem.So next I tried using the LogonAPI (advapi32.dll ->LogonUser call) to login as the user account that is a local admin on all workstations, impersonated the resulting WindowsIdentitiy and tried running just the original deComputer instantiation. When I do this every property, excepty Path, returns an OLE exception..
I planing to develop an application which can connect any remote server and pick the configuration information from server and show it in my desktop.
