difference between a console application and a Windows 
application is the way in which the program gets user 
input. A console application gets keyboard input through 
the Console.Read or Console.ReadLine methods; a Windows 
Forms application gets keyboard (and other) input through 
events.

windows forms provide the graphical user interface (GUI) 
where as console is the character user interface(CUI)
you have to use the hard code to develope the application 
using console, lots of thing you must remember where as the 
windows forms development is more user friendly and easy to 
use.

Console Applications are command-line oriented applications
that allow us to read characters from the console, write
characters to the console and are executed in the DOS
version. Console Applications are written in code and are
supported by the System.Console namespace.

Console applications are command line applications.We have 
to give inputs through keyboard without use of mice.But, in 
windows applications, users should give inputs through mice 
without use of keypad.

it is very speed..we can use this application for billing
pupose

use following code in button click event
System.Diagnostics.Process.Start(@"\write physical path of 
exe file");

Sorry, in the above code, after file name you can give 
comma seperated values of arguments which you want to pass 
as input value in exe file,

Shell("C:\WINDOWS\system32\calc.exe", 
AppWinStyle.NormalFocus)

Shell("C:\WINDOWS\system32\calc.exe", 
AppWinStyle.NormalFocus)

Shell("C:\WINDOWS\system32\calc.exe", 
AppWinStyle.NormalFocus)

Shell("c:\WINDOWS\system32\calc.exe",AppWinStyle.NormalOcus)

Shell("C:\WINDOWS\system32\calc.exe", 
AppWinStyle.NormalFocus)

just configure the report datasource by database

There are 5 objects in asp.net


  1.Response:This object is to response to other eg:

  2.Request:This object is request from server
  
  3.Application: This object is store global information of
application.

  4.Session:This object used store the values into variable.
  
  5.Server:

there are six object in asp.net.

6.object context object.

i am student of BCA and i am making project on hotel 
management in vb.net.i want to know some more categories 
that are available in hotel with database.

i am bca student .I want to sample Hotel management project 
in vb.net because 
still now i am doing that project for small hotel.the front 
end is vb6.0 and back end is oracle or sql

I will write code of value assignment in UserAddedRow event 
of grid.

eg.

Name of grid -grdSticker.
const iRollNo as integer=0

grdsticker.rows(e.rowindex-1).cells(iRollNo).value=7

System.Object

system.web.ui

System.Object is base class of .NET

system.data.sqlclient 
this is the base class for .net

Page Class

System.Object Is The Base Class Of All Derived in .net

1.through satellite assembly we can develop assembly and 
(if we want to use in any language like chines,etc and we 
can use it anywhere}


2. garbage collector run after a particuler point of time 
may depends on memory requiremtnt or time
first garbage collector check unused resources from memory
from generation first(which is L2 cache)and then find any 
references in genertion second(RAM)and then in third 
generation (virtual memory)

when garbage collector find any unused resources, it put 
that object in finalizition quere, for destruction of 
object and free memory from unused resources

and there is a thread is associated with which free objects 
one by one from this queue

and we can call  explicitly  the GC
like GC.collect(int )(here int is the generation number)

Satellite assembly:Assembly containing no executable code—
only resources. Typically, satellite assemblies are used 
for storing localized data. Satellite assembles can be 
added, modified, and loaded into a .NET application at 
runtime without recompiling. Use the Assembly Linking 
Utility to create satellite assemblies by 
compiling .resource files.

Satellite assemblies are often used to delpoy langauge-
specific resources for an application.  These language 
specific assemblies work in side-by-side execution because 
the application has a separate product ID for each language 
and installs satellite assemblies in language-specific 
subdirectory for each language.

create view <Viewname> as
select a as A,b as B,c as C 
from <tablename>
where <whereclause{optional}> order by A

CREATE VIEW view_name AS
SELECT column_name(s)
FROM table_name
WHERE condition

Using Views
CREATE VIEW [Current Product List] AS
SELECT ProductID,ProductName
FROM Products
WHERE Discontinued=No

CREATE VIEW vino (view_name) 
AS
SELECT mark1 (column_name(s))
FROM stud(table name)
WHERE avg>80 (condition)

CREATE VIEW <View Name> AS <Query Goes here>

CREATE VIEW table_name [ ( column_name1, 
column_name2, ... ) ]
  AS SELECT ...

EX:
CREATE VIEW ViewOfTableA AS SELECT col1 FROM TableA

First create crystal report.In the interface of report i.e
aspx form to display report,add report document as
Toolbox-->Components-->ReportDocument.
Call the sub routine CreatePDF to display report.
rptProduct is the name of crystal report and docProd is the
name of report document.

Does TCS interviewer asked this question .. ????

tcs will not ask this quiston

imports microsoft.win32

dim svr as new SQLDMO.SQLServer

svr.executeImmediate("RESTORE DATABASE<DATABASE NAME> FROM 
DISK =<DATABASE PATH NAME> WITH REPLACE")

really TCS interviewer asked this question.........??????ya 
tu fek raha hai......

VB.Net is Case-Insensitive while C# is case-Sensitive.

Thank u Sonia
I Know That Feature But Do You Any Other Feature 
Rather Than Syntax .

VB.Net does not support pointers but C# supports pointers

There is a documentation facility in C# (If you comment 
using ///This is my comment/// u can generate a document 
using Commands . I think this option is not in VB.NET

There is no Performance difference in BOTH Since both are 
running under CLR

VB.NET also doesn't support operator overloading. Due to
unsafe code.
And

VB.NET instantly compiled our code, help in small
development work and disadvantage is it cause slightly delay
in case of Large Development.

Dear Konthanppan ,
Comment related point stated by you is not true as VB.net 
provides it with ''' in replacement of /// in C#.

One big point is 
In VB.NET "SHARED CLASS" can be created but in C# Static 
class is not possible.

vb.net utilizes cpu 100 percent 
but c# doesnt ...
vb.net not  supports pointers
but c# supports ........

vb.net is very userfriendly

vb.net support optional argument for method parameter where as
c# not.

Linux Does Not Support .NET .
if You Have To Run The .NET on Linux Then You have Make 
Your on FrameWork which is Compatiable With Linux or You 
Have Purchase From Market as Thired Party Software

Microsoft released mono lithic version for linux OS. Here
you can done development as well.

yes, or not, linex os does not support the vb.net 
platform , but we use vb.net in linex with help of third 
party software....

yes,linux support .net
