Why doesn't an exception get thrown when this function is called when there is no ConnectionString set for the Connection? I just spent 15 minutes debugging and staring at it and finally figured out it needed the connection string. Shouldn't an exception get thrown?

In this situation, my application can connect to the MSSQL server in one of two ways; via a direct TCP/IP connection (WAN) (IP's filtered using RRAS in 2003 Server) or via a VPN connection. The application will first try to open the connection using the WAN connection string and if it can't, then it tries using the VPN connection string. My issue is, I set the connection timeout to 5 seconds for the first attempt but it's taking way longer than that to return an exception. The order in which I attempt to open the connection doesn't really matter. I have looked at the ConnectionTimeout property after changing the connection string and it does indeed show 5 seconds. It appears that the connection timeout value is being ignored.

My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application.

View 2 RepliesI'm writing a Windows form application in VS 2008. In the application I need to move among several SQL express databases (.mdf). I'm using the following commands to change the connection:
Me.MyTableAdapter.Connection.Close()
Me. MyTableAdapter.Connection.ConnectionString = "NewString"
Me. MyTableAdapter.Connection.Open()
I can see the form is showing data from the 2nd database. However, When I tried copying the 1st database (for a Save as function I'd like to implement), I got a system error saying "Cannot copy MdfFile: It is being used by another person or program.". Actually, I found all the visited databases were "being used" untill I closed my application. How do I break the connection completely?
I have been struggling with the construction of an Access connection string. Here's the problem.My Visual Basic 2008 project is located in a disk partition on my hard drive that I have named S:. My Access MDB file is in the same location.When I deploy the application it obviously will not be in an S: drive on the user's machine. My concern is that if I construct the Connection String using the file designations on my computer as:
(Provider =Microsoft.Jet.OLEDB.4.0; Data Source =S:MyApplicationmydatabase.mdb; User Id =admin; Password =
The deployed application won't know where to look for the data file. I know there are some shortcuts that will allow me to construct the connection string, but I do not know either the designated names or where to find them.
