code for catching error and saving in database in asp.net

 void Application_Error(object sender, EventArgs e)
    {
        //Code that runs when an unhandled error occurs
     
        //PS: This functionality stores all errors in database and these errors can be vieved
        //directly in database in 'ErrorLog' table. Or can also be viewed by browsing the
        //page 'errorlog.aspx' directly from the root of application.
     
        //Note: This logic will failed only in the case;
        //if database connection will not established due to some reasons.
        //so this is single case and can be trapped by developers. OR
        //In web.config; set <customErrors mode="Off"> and see the error.

        clsGenericClass objGen = new clsGenericClass();
