Access :: Error : ExecuteNonQuery Requires An Open And Available Connection?

Apr 15, 2010

We are currently migrating our test databases to a new server and I am switching one of our sites over to use them. When running the application from my development box it hits the database just fine. However when I compile and push the code out to our test server and try to use the same datbase I get the ExecuteNonQuery requires an open and available Connection. The connection's current state is closed error. I cannot seem to figure out why. Also when I point the site at our old test server it works just fine.

DataSource Controls :: Error 40 - Could Not Open A Connection To SQL Server

Jan 8, 2010

I have an application with a few dbml files to connect to several sql servers in order to import data from one to another using Linq to SQL.

There are 2 connection strings with integrated security and in one I provide user ID and password.

It all works great in the development workstation. I've then wrapped the dll project and deployed the asp.net application to a test server. Then, when I tried to run the application to import the data, I got a connection exception:

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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

I figured out after some debugging the problem is with the DataContext whose connection string is the one I provide user ID and password. Now, the funny part is that the same connection string works if I create a udl file and test it. And again the same connection string works with my development workstation.

Access Query Requires % Char In Like String?

Jan 11, 2010

I am building a page which has to search an access table with the text input entered by the user. The thing that is puzzling to me is that the functionality works only when a '%' is explicitly added to the text input at the begginning and end.

If I add '%' programattically in the code behind file, it does not work.
code snippet ( asp page):

<asp:AccessDataSource ID="AccessDataSourcex" runat="server"
DataFile="~/App_Data/company.mdb"
SelectCommand="SELECT [ID], [emp name] AS emp_name, [emp title] AS emp_title FROM [EmpMain] WHERE ([emp name] like [code]...

//the below line is of no use, the % char has to be in the text input

//txtSearch.Text = "%" + txtSearch.Text + "%";

GridView1.DataBind(); <---- this works fine

<--- this does not work, even if I add % chars programatically..


My question is: why does it not work when I programattically add the '%' chars to the search string..

Security :: Access Data Source Always Requires Authentication?

May 19, 2010

I am new to developing asp.net. I have a Microsoft Access database file (.mdb) I am including as a data source on a form. This populates a drop down list on the page. When I run the page in a browser it immediately asks for authentication. If I put in my windows username and password the page pulls up fine, and the drop down is populated with the data. If I don't, it just give me a 403 error and says I'm not authorized. I cannot figure out how to make this page stop requiring authentication. I have only tried one thing. In the web.config file there is an attribute called authentication. It was set to "Windows" I tried setting it to "None" but that did not appear to have any effect. It still asked for my username and password. How can I make an asp web page using a Microsoft Access data source not reqire user authentication to view the web page?
