can we move existing asp.net applications to dotnetnuke portal?

if yes can you pls tell me the procedure

if not what should i have to do.....do i need to recreate and write whole asp.net web application for dotnetnuke

Here I am giving some info relating to My application....pls have a patience and read it.

My project is recruitment process...here we have developed the project which does the Whole automation for the recruitment companies...

My project software requirements are  

 DotNet 2005, Sqlserver 2000 .

our architechure is    DAL DataAccessLayer.....which inlcudes No of classes =No of Tables in the Database

each class inlcudes the methods for insert, update , delete, View.

 In our project we used almost all controls from vs2005.net

and we are building menu dynamically ...based on the database data

..............

For this If i need move this application to DotNetNuke4.4.1...what i thought is

just change every page as .ascx (user control).  making some changes in the code

then we can move the total project as a module....But the problem here is when redirecting from one page to other page

we are using some Query strings to pass some information from one page to other page. In Dot NetNuke how can we redirect and how can we pass query strings from one page to other page.

Hmmm ... really the best way that this sort of thing would work is if you first turn you thought process around.

DNN is a framework - it is designed as a HOST system with Authentication,Layout,Content,DataAccess all brought together into a single system - not as a block of code that can be tacked onto something else.

So to really get your own webapp working with DNN - your webapp would need to be integrated with the DNN framework - not DNN integrated with your app.

1. Your appliction would need to be turned into a set of Modules - either compiled or dynamic in type.
2. Ideally your data access would be converted to DNN DAL or DAL+
3. Once converted - then there is no need for seperate user systems - just a single membership provider hosted by DNN
4. Now you can use ANY dnn module as a part of your site.
