Can someone show me how I would pass an HttpRequest object into a class library using VB.NET?
Here is the problem:
I have a class library, and one of the possible inputs into this class library is the System.Web.HttpRequest. However, once I separated the classes and placed them into a class library (they were initially coded directly into a new website project, which hada access to System.Web.HttpRequest), I no longer have access to this object!
I see there is a System.Net.HttpWebRequest class available though. Can I use this to accept an object of type System.Web.HttpRequest? And how would I do this? Since this seems to be a very advanced .NET question, and I am desperate to move the code to a class library (so I can call the class library from a web service), I am awarding 500 pts to whomever or whoever can show me how to be able to accept the System.Web.HttpRequest object in a class library.
Thanks so much for your help.

Or if you really meant the System.Web.HttpRequest class:
Public Sub foo(r As System.Web.HttpRequest)
'TODO: implement
End Sub
Public Sub foo(r As System.Web.HttpRequest)
'TODO: implement
End Sub

No, sorry, I guess I did not make myself clear.
Here is the scenario. I have a System.Web.Httprequest object from a Webservice (or a Webpage). I have a set of class libraries, that do NOT HAVE ACCESS TO System.Web.Httprequest (try to create a new class library and do an Imports System.Web and you will see what I mean).
So my question is, what code do I need to use to be able to cast or do whatever, in order to use an HttpWebRequest object in a class library using VB.NET? Sure, I can do one or the other above, but that does not help me, since I have an object of type System.Web.HttpRequest, that is passed into a classlibrary, with, as far as I can tell, only a System.Net.HttpWebRequest,
Is that any clearer? And thanks so much for the response.

So, using your example, I want to use:
Public Sub foo(r As System.Web.HttpRequest)
'TODO: implement
End Sub
But from inside a class library...but if you go into VS 2005 (or 2003, I guess) and create a new 'Class Library', and type in:
Imports System.Web. *you will not see HttpRequest as an available object*
Which is the problem I am having!
Public Sub foo(r As System.Web.HttpRequest)
'TODO: implement
End Sub

Yes, of course you can. But you will not find a class *inside* System.Web called 'HttpRequest' So if you try to define a variable called:
Dim orequest As HttpRequest
You will get an error.
If you create a new *website* however, and do an Imports System.Web and then define something as:
Dim orequest As HttpReqest
You will not get an error.
And this is the problem.
Dim orequest As HttpRequest
You will get an error.

So, if you read my first sentence of the scenario now:
"I have a set of class libraries, that do NOT HAVE ACCESS TO System.Web.Httprequest (try to create a new class library and do an Imports System.Web and you will see what I mean)"
You will understand what I said?

The approach I outlined worked for me. I was, in fact, able to create a new object of type HttpRequest.
As I stated, I added the System.Web reference to the class library project before importing System.Web.

Unfortunately, I *do* have a System.Web already in the class library. I would need something that actually solves this problem of 'how do I access an System.Web.HttpRequest object in a class library? Since the class library already *has* a System.Web reference, but it doesn't have access to any of the classes I need, how do I actually get at it? To I have to do some conversion from a file stream or something? And even if I do have a file stream, how do I then convert that back to an HttpRequest object?

Can you give me specific instructions on what you did?
ASKER
Aha. Yes! I see. Darn, but I should know that. Thank you both for your help. Now, since you both helped in answering my question, you shall have to share again, Chaosian. :)

Hmm. Well, I tried to give the accepted answer to Chaosian, but somehow, it did not work right. Sorry Chaosian...I did give you the balance of the points though...
LOL... no problem. Glad it's working!
Sometimes those references can be tricky. Since everything references System by default, System.Web shows up even if you don't have a reference to it... but none of the System.Web classes are available.
Seems like Microsoft could have made the process a little simpler.

Thank you Chaosian. Could you help me with my other 500 pt question? The problem I have reading and updating the appconfig file? You definitely are an expert!
I'll see what I can do :)
