I'm a bit new to VB.NET and I have a database which I want to connect to an access backend stored on a network drive for multiple users. I can view the Database in the solution explorer and the directory defaults to the project folder. How can I specify the directory to pull from my network drive? VS has copied this datasource and imported it locally which is fine for testing, but i need the file accessible for multiple users. Is this something I do when publishing?

I developed a Visual Basic Program in my laptop. I can run the program form my C Drive and works perfectly.
Then I put the program in a Share Drive and:
1. If I run the program from my laptop but in the Share Drive I get this Error[url]...
2. If I run the program from my desktop and the Share Disk it is works perfectly.
3. If I run the program from a different user desktop and the Share Disk I get this error[url]...
I suppose it is a Security Issue or something like that but I am not totally sure and I do not know how to fixe it.

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 spent quite awhile trying to figure this out and not one single combination of path strings let this happen.
I usually error'd with the path is not found, part of the path could not be found, or wrong user name and password.
All I am using is the <asp:fileupload>.

In the beta version of Beta2 of Visual Studio Professional, when I choose add new connections, I can select a I can select a " SQL Server (SQL Client)" datasource, which works great with my SQL Server Express DB running on the local machine.
In VB2008 Express, though, I can't select a "SQL Server" in the datasource dropdown. I can only try to connect to a Microsoft SQL Server Database File.
When I actually try to connect using the .mdf file that is being managed by my local SQL Server, I get an connection error -- can't make connection to the server (and the usual message about enabling remote connections".

I 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;

Do you know which module in VB.net will allow me to connect to a file (mdf/mdb) and SQL Server (not at the same time but to change in runtime).Or do you know of two modules which have the same API?
I'm building software which I will wont work both locally and on a server. But I don't want to have to go changing all of my code just because I'm using a different modules. I know VB.net, but I've never used databases.There's so many different database connectors its confusing!
