Calling Connection String From Webconfig File?

Jun 9, 2010

I'm using Visual Studio 2008 and SQL Server 2008 Developer to create a website.

I'm trying to test a connectino to a local database in my computer.

What I did is create a connection string in the webconfig file like this:

[Code]....

Then I want to call that connection string like this in the default.aspx.cs file I write the following code:

[Code]....

I'm not getting any error or warning in any of the code but when I run the page I throws me an error telling me:

The connectionstring property has not been initialized.

If I run with debug on it shows this:

[Code]....

Line 22 in red.

I don't know what I'm doing wrong since VIsual Studio does not tell me there is an error, it just seems like it cannot make the connection.

Configuration :: Webservice WebConfig File Not Recognized By Windows App?

Mar 2, 2011

I have created a webservice, which debugs fine with no errors, and published this on my localhost server for testing.

I have created a windows app which calls the webservice but am hitting problems as soon as I reach the point where the webservice tries to connect to its database.

The connectionstring is held within the web.config file of the webservice as

>><connectionStrings>
<add name="MyConnectionName" providerName="System.Data.ProviderName" connectionString="server=MyServerName; database=MyDataBaseName;uid=MyUser;pwd=MyPassword;"/>
</connectionStrings>

and called within the code by using the statement

>> System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionName"].ConnectionString

, and as I said before, this works perfectly when debugging the webservice application directly.

However, the windows application is not seeing the connection properly, if I use the statement as above I get a debug error stating that it is a NULL reference. If I change it to

>> System.Configuration.ConfigurationManager.ConnectionStrings[0].ConnectionString

I no longer get a debug error, but the connection is not made. On testing the above code it believes the name for connection 0 is "localSqlServer" and in both the web app and the webservice the error below is returned.

>>An attempt to attach an auto-named database for file \MyServerMyDirectoryMyProjectMyProjectApp_Dataaspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

why the windows application see's the correct connection string code as null? Is there additional security I need to add for the web.config file to be accessible? Or does the connection strings need to be relicated within the app.config of the windows app?

Both applications are written in C# and I use Visual Studio 2010, ASP.Net version 4.0.30319

C# Database Connectivity Getting Into Mess

Jan 31, 2011

I'm just starting development on a new website and am trying to do it correctly, that is, with a DAL and not with queries in code which I had before. I understand the principles of it all, but I am finding this DAL with table adapters and wizards that do too much to be really messy to work with. Does anyone have any recommendations on what I should be using instead and a link to a tutorial on how to get going quickly with it?

Web Forms :: Set Pooling / False In Webconfig?

Mar 5, 2010

I'm not having much fun with connection pooling. The website I've written does dip into the SQL server all the time and quite a lot of times per page. Every time I nip into the SQL Server to get or set something I open a connection...

comGeneral.Connection.Open()

... do or get what I need and then close it. From what I've read any of the following should close the connection and return "one connection" (?) to the pool (top one, only if reading)....

rdrGeneral = comGeneral.ExecuteReader(Data.CommandBehavior.CloseConnection)
comGeneral.Connection.Dispose()
comGeneral.Connection.Close()

... but that's not really working for me and I keep hitting the default max 100 open pools. So I've been doing all 3 of the above (again, top one, only if reading). But alas, still the stupid thing (Yes, I am aware I'm the stupid one) keeps hitting the max.

My new plan is to set pooling to false (pooling = false ?) across the entire website and take the performance hit which wont be terrible because I don't really do anything too demanding. Trouble is I don't know how, other than setting Pooling = False, but where exactly in the webconfig would this bit of code go?

Configuration :: Custom Web App Integration Into Sharepoint With MS-Access Connectivity?

Jan 10, 2011

Ive integrated a custom asp.net web application into a Sharepoint site by creating a virual directory, that contains my web app files, that points to a directory in the Sharepoint inetpub folder.

On my local dev server I can access all my web app pages just fine by typing in /virtualdirectoryname/page.aspx

My Problem is that: When I deploy to my Live Test server that is internet facing, none of the pages that make a MS-Access database call will work.

The Error I receive is '[SecurityException: Request for the permission of type 'System.Data.Odbc.OdbcPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]'

I have researched the issue online and tried numerous solutions which include giving all the assemblies in my application a strong name, and modifying the security policy to trust this strong name.

My Custom Web App consists of 2 projects

1. A Class Library Project (Data Layer)

2. A Web Application Project (Web Layer)

My .mdb database file is stored at root level within the Virtual Directory.

I have 1 class in the Data Layer (ClassConnect.cs) that when instantiated, creates the ODBC connection for all other pages to use (OdbcConnection dbConn = new OdbcConnection();)

I have a Connection String stored in the web.config file that is as such. When I deploy to the Live Test Server I change the path in this connection string, because I haven't figured out yet how to get a relative path that works.

I also place the dll's for my 2 projects in the Sharepoint bin folder.

Could anyone suggest what might be the dfference between my Local Dev Server and the Live Test Server and why I might be getting these errors.
