ASP 	ASP.NET

Control events for text button can be handled at client

handle at server side.
  	More error handling.

• ASP .NET has better language support, a large set of new
controls and XML based components, and better user
authentication.
• ASP .NET provides increased performance by running
compiled code.
• ASP .NET code is not fully backward compatible with ASP.
• ASP .NET also contains a new set of object oriented input
controls, like programmable list boxes, validation controls.
A new data grid control supports sorting, data paging, and
everything you expect from a dataset control.
The first request for an ASP.NET page on the server will
compile the ASP .NET code and keep a cached copy in memory.
The result of this is greatly increased performance.
ASP .NET is not fully compatible with earlier versions of
ASP, so most of the old ASP code will need some changes to
run under ASP .NET. To overcome this problem, ASP .NET uses
a new file extension ".aspx". This will make ASP .NET
applications able to run side by side with standard ASP
applications on the same server.

Since the data inside the single-quoted string is not parsed
for variable substitution, it’s always a better idea
speed-wise to initialize a string with single quotes, unless
you specifically need variable substitution.

if in the special character is there then initialize with
double quotes else single quotes, as it will become fast.

if in the string,substitution is needed then initialize with
double quotes else single quotes, as it will become fast.
