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.

i am getting the connection string in my code behind file when i use the appliaction variable (webform1.aspx.vb)

When i try this with my class i am getting the error.

Do i need to import any namespace in my class file to access this application variable in my class??

thanks,

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.

Then what is the use of asking question without placing sample code of that customized button.

That's smart.

Why don't you have a search on google and come back with specific questions rather than asking the entire concept ?
