Is There any othet solution? Please Help to solve this problem.

hi all,

I have created an Application level connection string variable in my Global.asax

Like:
Application("glbConnection") = con.getDBConnection()

I accessed that variable in My Business class like,

con As IDbConnection = Application("glbConnection")

But i Got the Error as ,

System.NullReferenceException
{"Object reference not set to an instance of an object."}

Message : "Object reference not set to an instance of an object."

I need to access my application variable in my Class file.
can anyone help me out to solve this problem

Thanks in advance.

To solve your current problem : I guess con.getDBConnection() returns a null value

To solve your next problem, I don't think you want to connect to your database throughout your website this way.

You say you have a business class. The business class should be in a separate project (your business project) which contains all db functionality and stuff and returns the required information to your user interface (in this case a website). In theory, you're website shouldn't be able to 'know' your connection string.

Erhm, in this case, you can better create a function which connects to the database for you in your businessfile

public void ConnectDb(object ConnectionString)<br />
{<br />
if (ConnectionString == null)<br />
return;<br />
<br />
con = new con(ConnectionString.ToString());<br />
<br />
}<br />

and call that function from your webpage

ConnectDb(Application["yourvariable"]);

For security reasons you should define your connection strings in web.Config, and access then using the ConfigurationManager.ConnectionStrings[^] properties

But using web.config for only a connectionstring isn't really the neat way, because handling a web.config is relatively pretty time consuming...

Do you mean using AJAX in ASP.NET, or using the ASP.NET AJAX framework ? How many images are there, that you need to make an AJAX call ?

Because you failed to provide a value for one or more parameters ? This is the ASP.NET forum, classic ASP belongs in the web dev forum.
