I am creating class libraries in my project so that I can update code without having to update the whole app.I created a class library project and added some code to it. I also added a reference to System.Data.SqlClient and also imported it into the class file.I am getting an error and I have never seen it before. Been looking online and not able to find an answer yet.

i am trying to connect to an MS Access database and I am getting an erro message on the following line of
searchtable_command = New SqlClient.SqlCommand(searchtable_string, testsearch_connection)
Error:'System.Data.Odbc.OdbcConnection' cannot be converted to 'System.Data.SqlClient.SqlConnection'.
Here my connection string:
Dim testsearch_connection As New Odbc.OdbcConnection("Provider=MSDASQL;Driver={Microsoft Access Driver (*.mdb)};Dbq=C:CesarAccessdatabase.mdb;Uid=admin;Pwd=;")
What am I missing?
Is there something wrong with my connection string that I would get this exception thrown back at me from my code? I have the string saved in the code and when I try to create an SqlConnection I get the exception above thrown and below is my connection string which is actually the address to my DB file.
Connection = "Data Source=.SQLEXPRESS;AttachDbFilename= C:Documents and SettingsTTTMy DocumentsBASEO.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"

I'm currently working on an existing ASP.NET project. At the moment I have to integrate
a new componant so for that purpose I had to change the framework target from 2.0 to 3.5. After regenerating the solution, I'm now dealing with a strange issue.
Here's the code :
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
<System.Web.Script.Services.ScriptService()> _
And the last line returns that error 'ScriptServiceAttribute' is ambiguous in the namespace 'System.Web.Script.Services'I have definitely no clue what's going on in my code ?! Is it an internal error of the ScriptService constructor ?

I have a VB.net 2005 application that will use both Access and SQL server databases. I have DSN namesfor both access and sql server database. I used OleDb.OleDbConnection to open the Access database and it works fine. I am trying to make it work with sql server database. Do I have to have to have separate source codes using Sqlclient.SqlConnection and its related name spaces? Can I use odbc.OdbcConnection name space

We have a VB web application that for some reason breaks when some clients run Windows Updates. To resolve the issue we have to force the application to recompile on the servers where the application is installed. In some instances we must do this multiple times and/or restart IIS as well to resolve the issue.
This didn't start happening until October of 2009, and then suddenly it happened all the time... but not for every client, and not with every update. It continues to happen and we have been at a loss to understand why. Is anyone else experiencing this issue or found a way around it? If there is something in our code that we can alter to keep this from happening I would love to know about it, as we spend time and resources troubleshooting and resolving an issue that doesn't exist until a Windows update runs and our application becomes un-usable until resolved.

Is it something dealing with the permissions set with the database server or something? I am new at .NET programming and I have been spinning my wheels on this for the past couple of days and I am at a loss. From what I research, this error should only occur if I was creating a web program, but I am not. It is a windows application.
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.
