Interview Qusetions - Part 1

Interview Questions
---------------------------

1. What is a private assembly?
a. An assembly which is used by only one application and which is placed in the installation directory of an application.

2. what is MSIL?
a. When we compile a c# program or any other program written in .net complaint languages, the source code is compiled in to MSIL. It is an instruction set in to which all .net prgrams are compiled and which is used by the CLR. It contains instruction for loading, storing, initializing, and calling methods.

3. What is CTS?
a. CTS means common type system. It defines how types are declared, used and managed in the runtime. This supports a variety of types and operations found in most of the programming languages and therefore calling one language from another does not require type convertions.

4. What is CLS?
a. CLS means common language specification. This enables interoperability in the .net platform.

5. What is JIT?
A. It is a compiler that converts MSIL to native code.

6. why do we use namespaces?
a. Namespaces are used to organise the code and to create globally unique types to avoid name collisions.

7. What is web farm?
a. Asp.net runs with in a process known as asp.net worker process. All asp.net functionality runs with in the scope of this process. A regular web server contains only a single asp.net worker process. A web farm contains multiple asp.net worker processes. Generally normal(small) web sites uses a single web server to satisfy the user requests. but a web farm(larger web sites) uses one or more seb servers to satisfy the user requests.

8. What is Globalization?
a. It is the process of design and development of applications that serve multiple cultures.

9. What is Localization?
a. It is a process of customizing an application for a given culture and locale.

10. What is a Thread?
a. A thread is a basic unit to which operating system allocates processor time. One process can have more than one thread. Each thread maintains exception handlers, scheduling priorities, and a set of structures the system uses to save the thread context until it is scheduled.

11. Differences between managed code and unmanged code?
Managed code:
1.It is executed under CLR.
2.It compiles to intermediate language
3. it provides services like security, exception handling, garbage collection etc
4. It can access both managed and unmanaged data
unmanaged code :
1. It is not executed under CLR.
2. It compiles directly to machine code.
3. It doen not provide security, exception handling, garbage collection etc
4. It can access only unmanaged data.

12. What is a bin directory?
a. It contains precompiled assemblies. this is useful when you need to use code that is possibly written by someone else where you don't have access to the source code but you have a compiled dll instead.

13. What is the use of enableviewstatemac property?
a. This is the attribute of a @page directive. This is used to check whether the view state has been tampered or not.

14. How to change a master page during rntime?
a. This is possible in the PreInit() event by setting MasterPageFile property to .master page.

15. What is serialization?
a. It is a process of saving the state of an object by converting it to a stream of bytes. the object can then be persisted to a file, database, or even memory.

Filling data from Database in to Dataset and then to Datagrid

LOADING DATA FROM DATABASE IN TO DATASET AND BINDING IT TO DATAGRID
---------------------------------------------------------------------------------
Dataset can not directly retrieve data from database. For this purpose we should use DataAdapter. DataAdapter acts as a bridge between database and dataset. This is used to retrieve data from Database into Dataset as well as to Update Database through Dataset.It supports insert, delete, update, select operations. It supports disconnected model.

Now we will see the steps required to fill data from database into dataset and then populate that data into datagrid.
For that

In .aspx page, in <div> section we should write
<div>
<asp:datagrid id="exdatagrid" autogeneratecolumns="true" runat="server">

DataSet Details

Filling dataset with data from more than one table
------------------------------------------------------------
To Fill dataset with data from more than one table from database and to
bind that data to datagrid we need following code

1. In .aspx file you need to write

&ltdiv>
&ltasp:datagrid id="grid1" runat="server" autogeneratecolumns="True">

&ltasp:datagrid id="grid2" runat="server" autogeneratecolumns="True">



Here we are specifying 2 datagrids to display data from 2 Tables.

2. In .aspx.cs file

1. First we need to open a connection

SqlConnection newconn = new SqlConnection(“Server=xxx;
InitialCatalog=xxx; UserId=xx;Password=xxx”);
Newconn.open();

In the above statement server= xxx means we are specifying server
name.InitialCatalog means database name from which we want to
retrive data. Userid, password are userid and passwords of user
for sql server.

2. Next we need to specify the sql statements(required operation)

DataAdapter da = new SqlDataAdapter("select * from firsttablensme;
Select * from secondtablename”, newconn)

note: here instead of command object we are directly using
DataAdapter.If you want you can use command object also.

In the above statement we are selecting data from two tables.
Newconn is the connection object.

3. Now, we need to fill the dataset

ds = new DataSet();
da.Fill(ds, “firsttablename”);
da.Fill(ds, “secondtablename”);

Here we are using Fill() method of dataadapter to fill the Dataset.

4. Now to bind this data to datagrid we need following code

grid1.DataSource = ds;
grid1.DataSource = ds.Tables[0];
grid1.DataBind();

grid2.DataSource = ds.Tables[1];
grid2.DataBind();

Here DataSource property represents the datasource of the datagrid and
DataBind() method used to bind data to the datagrid.

Note: you can also use caption property of datagrid to specify the table caption
Ex: grid1.caption = “xxx”
here Xxx represents cation for the table displayed by datagrid.

a ) We can assign inside a constructor

88. Why we use the sixeof operator?
a ) If we want to know the size of any data type you can use sizeof operator.

89. What are the disadvantages of distructors in c#?
a ) 1. They are non deterministic. means there is no way to know when an object's destructor will actually execute.
2. Implementation of destructor delays the final removal of an object from memory. means objects that have destructors are removed in 2 passes. in the 1st pass only the destructor will be called with out removing object and then the 2nd pass removes the object, which is time taking and which may effect the performance.

a ) A class can have only one static constructor.

13. What is method overloading?
a ) It is a process of creating methods that have the same name but with different parameter lists and different definitions. This method overloading is used when you want your methods to do same tasks but using different input parameters.

14. What happens when we use ‘private’ modifier to a constructor of a class?
a ) When we declare a constructor of a class as private then we can’t create a objects of that class and we can not use that class as a base class for inheritance

15. Can we overload constructors?
a ) Yes

16. What are instant variables?

Directives for Asp.Net Web Pages

Directives are used to specify the settings used by the page or usercontrol compilers to process pages or usercontrol files
There are 11 types of directives1.@Page: This is used to define page specific attributes. It is used only in .aspx files2.@Control: This is used to define Control specific attributes. It is used only in .ascx files3.@Master: This is used to define masterpage specific attribute. It is used only in .master files4.@Import: This is used to import a namespace in to the current page or usercontrol5mailto:5.@Register: This is used to render usercontrols and custom server controls in to a current page or usercontrolmailto:6.@Assembly:: This is used to link a page or usercontrol in to current page or usercontrol8mailto:8.@Implements: This is used to implement a specific .Net framework Interface in to current page or usercontrol9mailto:9.@Outputcache: This is used to apply cache techniques in to the current page or usercontrol10.@MasterType: This defines a class or virtual path used to type the master property of a page11.@Previouspagetype: This is used to create a strongly typed reference to the source page from the target of a cross page posting.

Differences between Asp and Asp.net

ASP----------
1. Asp supports interpreted model2. In asp you must place all directives on the first line of a page with in the same delimiting block3. Asp uses only 2 scripting languages vb script and java script4. Asp has no inbuilt facility for Validation of controls. Developer has to write code for both client side and server side validation
ASP.NET------------
1. Asp.net supports compiled model2. In asp.net you can place directives at any place in .aspx file . But standard practice is to place them at the begining of the file3. Asp.net is not constrained to 2 languages. we can use any .net complaint languages like c# vb.net etc4. Asp.net inbuilt facility for validation of controls. There are a set of validation controls which are easy to implement.

Goals of Asp.Net 2.0

The Goals of ASP.NET 2.0---------------------------They are1. Developer productivity2. Administration and management3. Performance and scalabilityDeveloper productivity: Much of the focus of the asp.net 2.0 is on productivity. It achieved it by introducing new controls like Gridview, detailsview, masterpages, sitenavigation and etc.Administration and management: Asp.net 2.0 now includes a Microsoft Management Console(MMC) snap-in that enables web application administrators to edit configuration settings easily.This allows system administrators to edit the contents of the machine.config and web.config files directly from the dialog instead of having them examine the contents of an xml file.In addition to this dialog, web or system administrators have a web based way called web administration tool to administer their asp.net 2.0 applications.Performance and scalability: One of the most exciting performance enhancements of asp.net 2.0 is its Caching capability. It includes a feature called SQL Cache invalidation.Before asp.net 2.0 it was possible to cache the results from sql server and to update the cache based on a time interval- for ex. every 10 sec so on. This means that the end user might see stale data if the result set changed sometime during 10 sec period. but by using asp.net2.0 new feature sql cahe invalidation the output cache is triggred to change when the result set from sql server changes.In addition to this asp.net 2.0 now provides 64 bit support.This means that now you can run your asp.net applications on a 64 bit Intel or AMD processors.
