I've been creating a local off-line program in c#, following tutorials and learning as I go. I learned to create SQL Server databases and connect to them through the model first tutorial on MSDN. My application is working at the moment but only on my computer.
I noticed this when I tried testing it on another laptop, without Visual Studio installed. The error that comes up reads
The underlying provider failed on Open
I'm not really sure why this is occurring and after researching this topic and reading several articles none of them have fixed it.
The SQL file was generated from an ADO.net model if that helps
The connection string as auto-generated by Visual Studio is as follows (formatted for readability):
data source = (localdb)\v11.0;
initial catalog = RandomInputMachine.logIn;
integrated security = True;
MultipleActiveResultSets = True;
App = EntityFramework
SQL Server version is 2012
Specific code where error occurs:
// Display all users from the database
var query = from b in db.Users1
select b;
Console.WriteLine("All users in the database:");
foreach (var item in query)
{
if (!deleteAll)
{
Console.WriteLine("---------------------------------------------------");
if (item.username != "agentender" || Program.user == "OVERIDE")
{
Console.WriteLine(item.username);
}
if (item.username == txtUser.Text)
{
if (item.password == GetHashedString(txtPass.Text, item.salt))
{
Program.user = item.username;
Program.loggedIn = true;
}
}
} else {
db.Users1.Remove(item);
}
}
How can I work out what is wrong?
