Question { 5699 }

why we should use more than one web.config files in our
application? I have two web.config files in my application.
One in the root directory and another one inside a sub
folder. When the application runs which web.config file
will run? why?

Answer

we can use more than one web.config file to meet the
different security and other configuration requirements of
different directories, and in any case web.config file of
subdirectory will take the precedence over file of root
directory.

Difference between ADO.Net 1.1 and ADO.Net 2.0 ?

Answer

ADO.NET 2.0 has new data binding model which reduce the
amount of code you write for data binding. It has more
compact dataset. ADO.NET 2.0 supports provider factories by
which you can write generic data access code. SQL Server
can now hast the CLR, also SQL notifications for ADO.NET
2.0 is new concept. some ADO.NET properties specially for
SQL Server 2005 like MARS (multiple active record set),
user defined data types, managed stored procedure by which
we can write S.P. in pure C#, snapshot transaction
isolation by which we can see relatively older data while
it is being updated by another transaction.

Question { 6452 }

how to retrieve data using web services in asp.net pls give
me the code and explain me briefly

Answer

To retrieve data from a web service first make method in
web service that query to the database and retrieve data
and return Dataset or the data type which you want to
retrieve (But web service can only return integer, string,
arrays, enum, xmlNode, Dataset etc). Make a proxy class for
your web service using VS or wsdl.exe. Now just make a
client class, make an object instance of web service in
your client class, and call the web method using this
object. I think now you can design code according to your
need.

hello friends..
when i deployment my project in the client machine that is
successful but whenever i try to run my project using .exe
file then it gives me error ".exe is not a valid
win32 application."
what i do somebody halp me pls

Answer

The error which you told in your question is because you
are trying to execute a file which is not actually
installed on the client machine. may be you are just
copying the files of your project on client machine. But in
order to run your project you need to make installer of
your project and then deploy it on client machine to make
your executable files specific to the client platform.
