An ActiveX Dll runs is an in process server running in the
same memory space as the client process.

An ActiveX Exe is an out of process server which runs in
it's own separate memory space.

Question 2 is the same as question 1.

Advantages of ActiveX Dll
-------------------------
1) An in-process component shares its client’s address
space, so property and method calls don’t have to be
marshaled. This results in much faster performance.

Disadvantages of ActiveX Dll
----------------------------
1) If an unhandled error occurs it will cause the client
process to stop operating.

Advantages of ActiveX Exe
-------------------------
1) The component can run as a standalone desktop
application, like Microsoft Excel or Microsoft Word, in
addition to providing objects.
2) The component can process requests on an independent
thread of execution, notifying the client of task
completion using events or asynchronous call-backs. This
frees the client to respond to the user.
3)If an error occurs the client processes can continue to
operate.

Disadvantages of ActiveX Exe
----------------------------
1) Generally slower than an ActiveX dll alternative.

DLL is a dynamic link library file that we can directly
execute. if we want to use dll then we need to add refence
in our progrma in Dll there NO Main function. EXE file is
excutable file that we can directly run.In exe It must be
one statr point mena Main function.

A dll use same memory space of client while running.
An exe use own memory space separate from client while
running.
A dll is much faster.
A exe can be run as standalone program.

DLL - inprocess
DLL runs along with the application which is sharing that
particular DLL. If we interrupt that application that DLL
also affected which in turn affects all onter applications
which is using that application.

EXE - outprocess
EXE runs seperately.

DLL isa inprocess component i.e. it runs in the same
process space (means sever n dll both share the same
process space) whereas exe is a outof process component
means server n exe runs in its own process space.

* In case of dll any error in dll causes makes the
application off whereas in case of exe it cann't

*dll is faster than exe

DLL is a dependent type of program. Every DLL has an entry
point method and Dll gets loaded only when a call to it is
made from any application for the first time.

Exe is a self-running type of program.

1)
DLL: Can not run independently. Runs with EXE.
EXE: Can run independently.


2)
DLL: Takes up space in memory in processess' memory space,
DLL is in-process component.
EXE: Takes up space in memory separately, EXE is Out-
process.


3)
DLL: Runs faster than exe.
EXE: Slower than DLL.

4)
DLL: error causes off the application.
EXE: can't.

5)
DLL: Doesn't have own main entry point, handled by other
method(s).
EXE: Have own entry point, handled by OS.

What do you mean by query string?

a web application needs to be created to accept the product name and quantity of a toy from a customer. After the customer has entered the product name the application needs to display the discounted price of the product to the customer (company is offering 35% discount on all products). The application should allow the customer to select the product name from a list box. and also while i'm data binding to a label with custom data binding with some declarations : "The Discounted Price is "+((System.Convert.todouble(lblprodprice.text)*(system.convert.todouble(txtqty.text)) - ((System.convert.todouble(lblprodprice.text)*(system.convert.todouble(txtqty.text)*0.35)). Where i need to give this declaration in asp.net 2.0.
