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.

In Visual Studio, I am attempting to create a Data Connection to a database in SQL server. Server Mgmt Studio is not running. When I attempt to add a connection in Database Explorer, to the AdventureWorks _Data database, I get the message "This file is in use.

There are no programs running except VB, except maybe for the SQL Server engine running the background.Please note that I can open and access tables within a database in code

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.

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'm currently working on an VB.net application using Win forms and SQL Server Express 2008. One of the major functions of our program is to generate work orders for field engineers. These engineers typically work in a factory and have to walk around the factory to complete these work orders doing things such as recording pressures and voltages of certain equipment. Right now they are printing out the work orders and writing down these values then entering them into the computer when they get back from doing the work.
We would like them to have some sort of handheld device we could push their work orders out to that would allow them to enter values/complete work orders and then come back and sync up with our app. Something like an ipod touch or maybe a bit larger seems like a good kind of device. Not really sure what kind of device would work for this and what OS it should run. I'm guessing it will be easiest if I can get something that can run SQL server on it. Also, how would I implement something like this?
I am using VS2010 and have been watching and learning from Beth Massi's great videos. I have built some test apps using her example of (under Server Explorer) - right clicking on "Data Connections" and selecting "Create New SQL Server Database, and in the server name just like she does, I type ".SQLEXPRESS", fill in the "New Database Name" and fill in my fields, build my tables, build a simple little windows form app. add new data source, etc. and everything works great. Then I try the "Add Connection" option again under Server Explorer and use the default (for me) of "Microsoft SQL Server Database file(Sql Client)", fill in a database file name (it creates a new one for me), "Test Connection" works, build my tables etc, and then build a simple little windows form app. add new data source and everything is great once again. Except I am not sure what is actually happening between these two options. Under the "Create New SQL Server Database option I see (in Server Explorer) a "myapp.dbo". Where is the actual database file? Under the "Add Connection" I see a "myapp.mdf" file in the Server Explorer. Also what happens when I "Publish" (deploy) my app? When I look under application files under Publish, I see the .mdf file listed as "Required" under the "Add Connection" option, but with the "Create New SQL Server Database" I don't see any database files listed? What is the difference between these two ways of creating a database for a VB Windows Forms Application?

View 1 RepliesI am having a small problem... I can connect to a local MySql Database using:
SQLConn.ConnectionString = "Data Source=servername;" & _
"Initial Catalog=databasename;" & _
"User ID=username;" & _
"Password=userpassword;"
Where servername is "localhost". I need to make a connection to an online database (same data structure). What should I put at the servername in that case? I do have all the info about the database in question (Domain, Ip, etc...). Which part should i use?
I can connect to both databases with SQL Server Enterprise Manager, so I know the servers are up and available. One of them is SQL1, the other is SQLTEST.In my program when I use the following connection string, it work connects just fine:
conn = New DBConnect("Data Source=SQL1;Initial Catalog=SignInspection;Integrated Security=SSPI")
However, if I change SQL1 to SQLTEST the connection times out I don't get any errors other than the timeout error.I can run the profiler on SQLTest and see that it is most definitely NOT even attempting to connect.
EDIT:Well, it's a moot point now because I got authentication working properly on our SQL1 server.
First off, the web server is running IIS and .NET. Users are logged in to the intranet using Active Directory, and the .NET page needs to retrieve their log-in credentials (username most notably). The database is SQL Server 2005, running on a different machine. But the .NET app needs to impersonate as another user to connect to the database.
To successfully do both of these things go to Windows > Run, enter inetmgr and hit run. Navigate to the site and right click > properties, then click on the tab titled Directory Security, click Edit.., make sure only Integrated Windows Authentication and Digest authentication are enabled. Enter your proper AD realm and click OK. Apply the settings/hit OK.In web.config you need the following lines
<authentication mode="Windows" />
<identity impersonate="true" username="myDomainMyUserName" password="123mypasswordgoeshere">
replacing, of course, myDomainMyUserName and 123mypasswordgoeshere with the username and password that has login rights on both your domain and your sql server. The connection string can probably be modified, but this is mine and it works:
Server=SQL1;Database=SignInspection;Trusted_connection=True;
