How to call an aspx page from a vb class?

[elizab]

Hi All,

How can I call an aspx page from a vb class. My vb project consists of only classes (forms are not present). I have given a reference to System.web. But I am not able to acces Response object or HttpContext.

Inside that class I need to use the response object for redirecting to an aspx page.
Can anyone help me.

Thanks in advance

I don't think you can use Request/Response object directly from your VB.NET dll (unless passed in by an ASP.NET app).

What exactly that you want to do?

My requirement is to call an aspx page from a vb.net dll. so that i can reuse the same dll.
I want to redirect to the corresponding webpage from a dll.
Hope the requirement is clear.

Thanks for raising help

You can pass the Request and Response objects from the ASPX page into the DLL. Then your DLL can use those objects.

Public Class MyWebHelper
Private m_Server As HttpServerUtility = Nothing
Private m_Request As HttpRequest = Nothing
Private m_Response As HttpResponse = Nothing

Public Sub New(server As HttpServerUtility, request As HttpRequest, response As HttpResponse)
m_Server = server
m_Request = request
m_Response = response
End Sub

Public Sub RedirectToLogin()
m_Response.Redirect("mylogin.aspx")
End Sub
End Class

In ASPX class:

Private Sub Page_Load(...)
If (Not IsLoggedIn) Then
Dim hlpr As New MyWebHelper(Server, Request, Response)
hlpr.RedirectToLogin()
End
End Sub

Private Function IsLoggedIn() As Boolean
' validate user
End Function

no, that is completetly unnecessary.

If you can be sure that the code will be running withing a web request (ie, this class/method will not be used by any win forms code) then you can ALWAYS get access to the current request by doing this:

System.Web.HttpContext.Current

This will give you access to the Request/Response objects, as well as Session, Application, and cookies.

Hope this helps.
