I have an application that uploads an Excel .xls file to the file system, opens the file with an oledbconnection object using the .open() method on the object instance. The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers).
string connectionString = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";") + "Extended Properties="Excel 8.0""
OleDbConnection connection = null;
connection = new OleDbConnection(connectionString);
connection.Open();
The exception comes on production server at connection.Open() some times, when I reset the asp.net worker process it started to work but after some hours/days It occurs again. how can I fix this issue which comes in production some times but very irritating, or there is some other work around.

We're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).
The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)
The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:
Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")
Dim cd As New System.Data.OleDb.OleDbCommand("SELECT * FROM " & strCSVFilename, cn)
cn.Open()
da.SelectCommand = cd
da.Fill(dtData)
The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string. What am I missing here?

Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:
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: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.

I am using forms authentication and authorization through roleManager. I have two Roles - "Customers" and "Employees". The redirection to the default page for the "Customers" role is working fine, but I get an oledb error stating that one or more parameters are not being passed when I redirect a user from the "Employees" role. The following is the code in login.aspx that handles the authentication of the user:
If myReader.Read() Then ' We have a match
If myReader(1) Then ' This is true if an Employee and false otherwise
If Not Roles.IsUserInRole(logInUser.UserName, "Employees") Then
Roles.AddUserToRole(logInUser.UserName, "Employees")
End If
ElseIf Not Roles.IsUserInRole(logInUser.UserName, "Customers") Then
Roles.AddUserToRole(logInUser.UserName, "Customers")
End If
FormsAuthentication.RedirectFromLoginPage(logInUser.UserName, logInUser.RememberMeSet)
Else
Response.Write("Invalid credentials")

I have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:
<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ ConnectionStrings:PgSqlConnection.ProviderName %>" >
</cc1:pgsqldatasource>
As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.

I have an app that connects to only one db for all of the data that the app has access to. My connection string is in the Web.Config file. In each of my DAL classes I have the following code that gets the connection string from the Config file. This works with no issues but I thought there might be a better way of doing this that I don't know.
If I wanted to change the name of the connection string that any of the DAL classes would use then I would have to change the name of the connection string in each of the files. I thought about creating a new class that would hold this then I could just instantiate a new instance of the class to access this with each of the DAL classes that needs access to it. Then if I needed to change the name of the connection string then it would only be in one place. I suspect there is an even better way of doing this that i don't know about.
