1 Difference between asp and asp.net
Ans- ASP: 1-asp is interpreted language based on scripting language like Jscript, vbscript.2- Asp has poor error handling concept.3- Asp has mix HTML and coding logic.4- In Asp limited oops concept available.5- Limited session and application state management.6- There is no in build XML support.
ASP .NET: 1- Asp .net supported by compiler and has compiled language support.2 - In asp net full oops concept available3 - Separate code and design logic possible.4 - Full proof error handling concept5 - Complete session and application state management.6 - Full XML support for data exchange
2 How do you do exception management?
Exceptions are a very powerful concept when used correctly. An important cornerstone in the design of a good application is the strategy you adopt for Exception Management. You must ensure that your design is extensible to be able to handle unforeseen exceptions gracefully, log them appropriately and generate metrics to allow the applications to be monitored externally.
3 If you are using components in your application, how can you handle exceptions raised in a component?
The best way of handling exceptions while using components is ... log those into database from component and just pass user friendly message to Interface who is calling component.
4 Can we throw exception from catch block?
We can absolutely throw exceptions in catch blocks. This is called bubbling the exceptions to one level higher. If catch block can not handle exceptions, then it can throw the exception that it caught, to its caller.
Ex protected void Button1_Click(object sender, EventArgs e) { try { Test(); } catch (Exception ex) { Response.Write(ex.ToString()); } } private void Test() { try { throw new Exception ("Dev"); } catch (Exception ex) { throw ex; } }
5 How do you relate an aspx page with its code behind page?
The topmost line of code behind file...<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
6 What are the types of assemblies and where can u store them and how?
Assemblies are the building block for any application and it can have dll files, exe files, html files etc.We have three types of assemblies.
1- Private assembly – can be shared by only one application.2- Shared assembly – can be shared by more then one applications.3- Satellite assembly – can be used to localize application into regional application.
We can store assemblies in gacutill.exe
7 What is difference between value and reference types?
Value type– it’s fixed in size and stored in stack (LIFO).if we assign a value to another it will create two copies.All primitives’ data types except string and object are example of value type.Value type drive from System.valuetype
Reference type – its does not fixed in size and they maintained system heap but they are also use stack to store reference heap. Two primitive types object and string and all non primitive type (class, interface, and delegate) are example of reference type.Reference type drive from System.object
8 Is array reference type / value type?
Array is reference type because its use address of value.
9 Is string reference type / value type?
String is reference type and stored in heap.
10 What is web.Config? How many web.config files can be allowed to use in an application?
The web.Config file is the configuration file of any application. This means it’s containing the configuration settings of web application like (authentication, authorization, tracing, debugging, connection strings).An application can have more then one web.Config file but root folder will be different for all. So we can say root folder can have only web.Config file.
11 What is difference between machine.config and web.Config?
Machine.config file is the configuration file for all the application in IIS. Web.Config file is the configuration for all the web application or folder.Machine.config file for the machine level configuration and web.Config file for the application level configuration.
12 What is shared and private assembly?
Private assembly – private assembly can be shared only one application. By default we use private assembly.Shared assembly – shared assembly can be shared more the one application.
13 What are asynchronous callbacks?
Delegates can also be used as Callbacks. Callbacks are used in many Windows API calls. You pass in a function pointer to the API call. When the API call gets finished with its job, it then “calls back” to the function via the function pointer you passed it. This allows your code to know when the API call is done. API (Application Programming Interface)
The framework provides an easy way to use a delegate with an API that needs a callback. Here's how. You can define and pass a delegate as a native function pointer several ways. Here are two. First we declare our delegate and the API call we want to make.
14 How to write unmanaged code and how to identify whether the code is managed / unmanaged?
Managed code – code produced by (VB.NET, C#, J#) .net framework language called managed code. Managed code run under the CLR. MSIL will be produced in managed code. Garbage collector runs automatically in MC.
Unmanaged Code – code produced by third party called unmanaged code. Unmanaged code does not run under the CLR. MSIL does not produce. Garbage collector does not run automatically in case of unmanaged code. Its run forcefully. (GC.Collector)
15 How to authenticate users using web.Config?
If we are using form based authentication at that time in the web.Config then we can set the authentication mode to “form”. Then we can specify user name and password which we were going to access.
<authentication mode="Forms"> <forms name="appNameAuth" path="/" LoginUrl="login.aspx" protection="All" timeout="30"> <credentials passwordFormat="Clear"> <user name="jeff" password="test" /> <user name="mike" password="test" /> </credentials> </forms> </authentication> <Authorization> <deny users="?" /> </authorization>
16 What are strong name and which tool is used for this?
The strong name contain information about the assemblies such as (name, version, number and the public key). It may be or may be not contain information about culture.Sn is a tool to create a strong name
Syntax: Sn – k mykey.snk
17 What is gacutil.exe? Where do we store assemblies?
Gacutil.exe is a tool provides by the .net framework. It is used to register an assembly in global assembly cache. Normally we store the assemblies in “c:\windows\assembly”.
18 Should sn.exe be used before gacutil.exe?
Yes it is mandatory to assign strong key name before placing it into the GAC. Because strong name contain the public key.
19 What does assemblyinfo.cs file consist of?
Assemblyinfo.cs file created by .net runtime where the information like version number, strong name and signature number stored.
20 What is boxing and unboxing?
Boxing – converting value type to reference type called boxing.Unboxing – converting reference type to value type called unboxing.
Class form{Static void main (string [] args){Int a=10;Object ob; // value typeOb=a;Int j;J=convert.toint32 (ob); //reference type}}
21 Types of authentications in ASP.NET?
There are three type of authentication...A) Form authenticationB) Window authenticationC) Passport authentication
22 difference between Trace and Debug?
According to Microsoft documentation there is no much difference between Trace and Debug Class. Debug only works in debug mode and trace works in debug and release both modes.
23 Differences between Dataset and DataReader?
Data Reader – datareader is a component that reads the data from the database management system and provides it to the application. The datareader works in connected manner. Its read the record from the database, pass it to the application.
Data Set – Data set is the class of using System.Data; it is stored to use multiple tables and its follow disconnected architructure. Its use to fill the data using data adaptor. Difference between datareader and dataset –
Data Reader – a) it is read only and forward only data.b) We can access one table at a time by using data reader.c) Its come under connected architructure.d) Its much faster the data adaptor.e) It can not persist the data.
Data Set – a) it defined with multiple tables.b) Its come under the disconnected architructure.c) It can not define with out data adaptor.d) It can persist the data.
24 What is custom tag in web.Config?
Custom tag allows you to create your own tag and specify key value pair for it.
25 How do you define authentication in web.Config?
In the authentication tag we have to specify the mode of authentication. It can be window, form, passport or none.Ex- <authentication mode=”window”>
26 What is sequence of code in retrieving data from database?
Sqlconnection con=new sqlconnection(@“server=servername;database=”databasename”;integrated security=true”);Sqldataadapter adp=new sqldataadapter(“Select* from employee”,con);Dataset ds=new dataset();Con.open();Adp.fill(ds,”employee”);Gridview.datasourse=ds.table[“employee”];Gridview1.databind();Con.close();
Oledbconnection con=new oledbconnection(string .formate (“provider=microsoft.Jet.OLEDB.4.0;data source={0};user id;”,system.io.path.combine(application.startupPath,”database”)));Oledbdataadapter adp=new oledbdataadapter(“select * from employee”,con);Dataset ds=new dataset();Adp.fill(ds,”table”);Datagrid.datasource=ds.table[“”];Con.close();
27 About DTS package?
DTS is the data transformation services. Its provide a set of tools that lets you extract, transform and consolidate the data from different sources to single or multiple destinations. We can create DTS solution as one or more packages.
28 What provider ADO.net use by default?
SqlClient is the default provider of ADO.Net.
29 where does web.Config info stored? Will this be stored in the registry?
Web.Config contains authorization/authentication session related information. It is stored in root directory of the application.
30 How do you register the dotnet component or assembly?
By making Strong Name key.Sn-k mykey.snkThe command line instruction will create an assembly using the Strong Name key.
31 what is stateless asp or asp.net?
Asp and Asp.net both are stateless because both are using HTTP protocol which is stateless.
32 Authentication mechanisms in dot net.
Authentication refers to the method used by the server to verify the client’s identity. This feature provides method to authenticate clients via a set of standardized and reusable methods that require or no modification.
There are three type of authentication mechanism in asp .net.a) form authenticationb) window authenticationc) passport authentication
Form authentication > allow application developers to provide a form to authenticating users in standardized way. Window authentication > window authentication used by default if we not use any authentication.Passport authentication > verify the user through the use of Microsoft passport authentication server.
33 State management in asp.net?
State management is a technique to preserve the data. We can categorize state management in two parts.1. Client side state management 2. Server side state management
Client side state management > client side state management is a technique to preserve the data on client side.
Client side state management techniques are-------a) view stateb) query stringc) hidden fieldd) cookies
View State > view state is a client side state management. View state can be use to store state information for a single user. View state is an inbuilt feature in web control to persist data between page post backs. You can set view state on\off for each control using EnableViewState property. By default view state property set to True.View state information of all the controls on the page will be submitted to the server on each post back. For reduce performance penalty you can set disable view state for all control which you don’t need state. You can disable entire page view state by Enableviewstate=false.
Ex- ViewState[“MyViewState”]=myvalue; //add items to view stateResposne.Write(ViewState[“MyViewState”]); // reading items from view state.
Advantages 1. Simple for page level data.2. Can be set at the control level3. Encrypted.
Disadvantages 1. Makes a page heavy2. Overhead encoding view state values
Query string > query string are used to send information one page to another page. They passed along with URL in clear text. Query string seems to be redundant. We can pass smaller amount of data using query string.
Advantage – simple to implement
Disadvantage – human readable, easily modify by end user.
.Hidden Field > Hidden field is used to store the data at the page level. Hidden field are not rendered by the browser
.its just like a standard control for which you can set its properties. Whenever page is submitted to the server then hidden field value also posted to server along with other control of the server.We can use hidden field in asp .net using following syntax...
Protected System.Web.UI.HtmlControls.HtmlInputHidden Hidden1;Hidden1.value =”Create hidden field”;String str=hidden1.value;
Advantages – simple to implement to a page specific data.- Can store small amount data so they take small size.
Disadvantages – not good for sensitive data.
Cookies > A cookies is a small piece of text stored at user’s computer. Usually information is stored as name- value pair. Cookies used by websites to keep the records of user. Every time a user visits a website, cookies are retrieved from user machine and help identify the user.
if (Request.Cookies["UserId"] != null)
{ lbMessage.text = "Dear" + Request.Cookies["UserId"].Value + ", Welcome to our website!";
}else
{ lbMessage.text = "Guest, welcome to our website!";
}
If you want to store client's information use the below code
Response.Cookies["UserId"].Value=username;
Server side State Management > server side is a technique to preserve the data on server side.
Server side state management techniques are.......a) application objectb) session objectc) profile
Application Object > it is a server site state management. Application object is used to store data which is visible across entire application and share across multiple user session. data which needs to be persist for entire life of application should be store in application object. Applcation.loack ();Application[“my data”] = mydata;Application.unlock();
Session Object > it is a server side state management. Its consume server side resources. Session can maintain data across the page. Session object scope is user level. We can also transfer the data one page to another page by using session state. Session[“Keyvalue”] = “New Delhi”;
Profile > Asp .net provides a feature called profile properties, which allow you to store user specific data. its just like a session object but it can manage the data after session destroy.
34 Types of values mode can hold session state in web.Config?
InProc - session kept as live objects in web server (aspnet_wp.exe)StateServer - session serialized and stored in memory in a separate process aspnet_state.exe). State Server can run on another machineSQLServer - session serialized and stored in SQL server
35 About WebService?
““Web service can convert your application into a web application, which can publish its function or messages to the rest of world.”’Web service is an application that is designed to interact directly with other application over the internet. In other word web service means are interacting with objects over the internet.
Web service is 1. Language independent 2. Platform independent 3. Protocol independent
The basic web services platform is XML + HTTPExample of web services – Weather Reporting-Stock quoteNews headlinesWeb service communications- web service communicate by using standard web protocols and data formate.HTTP, XML, SOAPAdvantages of web services- web services messages are formatted in XML and message send via HTTP protocol which is easy to send other computer easily via internet.
36 what are Http handler?Http handler is a process that runs in response to request of application. In asp .net when user send the request of web application then http handler give the response via the page handler.
37 what is view state and how this can be done and was this there in asp?View state is the client side state management. View state can be use to store state information of single user. We can set the all control property in a form true by using EnableViewState = true. View state send the information of all control to the server on each post back. Which control u don’t want to carry state then you can set the property EnableViewState= false.ViewState [“Controlname”] =MyViewState;Resposne.Write= ViewState [“Controlname”];
38 Types of optimization and name a few and how do u do?
39 About DataAdapters?Data Adapter is a component that exists between dataset and physical database. It contains four different commands (select, insert, update, delete). It uses these commands for fetch the record from database and fills in the dataset. And updates done in the database.SqlDataAdapter adp = new sqlDataAdapter (“Select * from Emp”, con);
40 what is dataset and Features of a dataset? The dataset contain DataTableCollection and DataRelationCollection. It represents a collection of data retrieving from the data source. We can use dataset with DataAdapters. Dataset works as a disconnected architructure. It work better then datareader because datareader reads only single value and work on connected architructure.
Features of DataSet > 1. Dataset works as a disconnected architructure.2. Dataset can contain more then one table.3. Dataset is XML oriented and so serialization is possible.4. Dataset slower then DataReader.5. It is a heavy object so its take more space.
41 How do you do role based security?
42 Differences between Response.Expires and Expires.Absolute?
Response.Expires specifies the length of the time ie 20 secondsResponse.ExpiresAbsolute specifies the time ie 12:12:10
43 Types of object in asp?
There are five type of object in asp .net which is given below..Request object > it’s used to access the information send a request from browser to server. Response object > it’s used to access the information about response from server to clientSession object > it’s used to store and retrieve information about particular user session.Application object > it’s used to store the information about applicationServer object > it’s used to access various utility function on the server.
44 about duration in caching technique?
Performance is the key requirement of any application. One of important technique which helps in the performance of application is Caching. Caching is the process of storing frequently used data on the server to fulfill subsequent requests. Duration in catching technique indicate how much time my cache will hold the data.<%@ OutputCache Duration="90" VaryByParam="None" %>
o Output Caching
o Partial Page Caching
o Data Caching
45. Types of configuration files and the differences?There are three type of config file..a) App.config file > its contain application specific settingsb) Web.config file > 1. it’s a security in asp .net application and how to secure application. Web config file does most of the work for the application the who, what, when, and where to be authenticated.
2 This is also called application level configuration file. 3 This file inherits the setting from Machine.config file.
Machine.Config file > machine config file contain the information of machine or entire computer. this is also called machine level configuration file. Only one Machine.Config file exists on a server.
46 Differences between ADO and ADO.net?Differencesa. Ado follows connected architructure, whereas ado. Net follows disconnected architructure.b. Ado used data reader to read the data from the database, whereas ado .net used dataset to retrieve the data
from database.c. Ado is faster then ado .net for accessing the data from database because ado can access data from one table
but ado .net access the data from multiple table at a time.
47 About Post back?
Post back is an event that is triggered when an action performed by a control on an asp.net page. For example when we click on a button control then the data of page will send to server for processing.
Protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) {
Response.Write("first time the page is loaded.");
} else { Response.Write("the page is loaded more than once");
}}
48 If you are calling three SPs from a window application how do u check for the performance of the SPS?
If you want to check the performance of SPS then you need to the Sql profiler.
#61607; Database
50 What is normalization?Normalization is a technique to design the relational database table and prevent the duplicity and also use to security and data integrity. Normalization also use for reduce the problem of data redundancy.
51 What is an index and types of indexes? How many numbers of indexes can be used per table?
Indexes are the method for faster retrieve the data form database or tables. Different types of differences area) Primary key indexb) Unique indexc) Hash indexd) Bitmap indexe) Function based indexf) B-Tree indexg) Virtual index
52 What is a constraint? Types of constraints
Constraint use for restriction of tables. Or we can say constraint is a rule which we want to apply on tables.We have two types of constraints Anonymous constraints and named constraintsWe have some useful constraints there...1. Primary key constraints2. Foreign Key constraints3. Unique Constraints4. Not Null Constraints5. Check Constraints 53 What are code pages?
Code page other name is character encoding. It consists of a table of values that describes the character set for a particular language.
54 What is referential integrity?
The feature provides by RDBMS that prevents user or application from inconsistent data. RDBMS have various referential integrity rules that you can apply when you create a relation between two tables.
55 What is a trigger?
A trigger is a database object that is attached to a table. In many aspect trigger is similar to stored procedure.The main different between trigger and stored procedure is trigger only fired when an Insert, Update, Delete, occurs.Create trigger tr_tablenameOn tablenameFor INSERT
56 What are different types of joins?
Joins > join mean fetch the record from more then one table or join is a technique to creating a list of records from more then one table, using all columns from all table involved or selecting only the desired columns from one or all of the tables involved.Types of joins are Inner join Outer join Cross join
Inner Join > it contain only match data form left table and right table.
Select empid, name, emp.depno, dep.nameFrom empInner join depOn emp.depno=dep.depno
Outer Join > it is like an inner join but if there are some condition then we use outer join. We have three type of outer join 1. Left outer join 2. Right outer join 3. Full outer join
1. Left Outer Join > All the records from left table and matching the record on condition from right table.
Select empid, name, emp.depno, dep.depnoFrom empLeft outer join depOn emp.depno=dep.depno
2. Right Outer Join > all the records from right table and matching the record on condition from left table.
Select * from employee;
ID name salary----------- ---------- ----------- 1 Jason 1234 2 Robert 4321 3 Celia 5432 4 Linda 3456 5 David 7654 6 James 4567 7 Alison 8744 8 Chris 9875 9 Mary 2345Select * from job;

Select e.id, e.name, e.salary, j.titleFrom employee RIGHT OUTER JOIN job ON e.id = j.id
3. Full Outer Join > all records from the left table and also all the record from right table.
Select from table oneFull outer join table two
Cross Join > all record form each row from the first table is combined with each row from the second table. its also mean it will produce Cartesian product of the set of rows from the joined table.
Select from employeeCross join job
57 What is a self join?A join joins itself called self joins.
58 Authentication mechanisms in Sql Server?
In Sql server there are two type of authentication window authentication and mix mode authentication.
59 What are users defined stored procedures?
Stored procedure is a database object and it is a set of pre compiled transect Sql queries. By stored procedure we can execute the DML and DDL queries in the database. We have some advantage of SPLike it does reduce the network traffic, enhanced security controls, it can pass 1033 parameters; it can be input or output parameters.
