I am implementing a custom membership and role providers where I need to store all the role/membership information in the user's session.
I am implementing these custom providers inside a class library project (different from the website project) and need to access the session in them. The idea is to store the role/membership related information in the session after retrieving them for the first time from the database.
When I try to access the Session using System.Web.HttpContext.Current.Session
I get this as a null object (Object reference not set to an instance of an object.
Why is the session turning out to be null?

View 2 RepliesI have a custom gridview control which is a class library project.I want to be able to specify the css class for the gridview which I can do.But I also want to set a default css stylesheet to the gridview. So if I don't override it using the cssclass property it must get it's cssclass from the default stylesheet I have in my project.
How can I specify the default stylesheet. I have a stylesheet in a folder called "Styles" in my project.
Best way to describe my issue with vs 2010.create a new website. create the App_Code folder. create a new class in the folder. put the line "x" in the class declaration. hit compile. And the website will compile with no errors. It's not "seeing" this new class as being part of the project best I can tell.
View 1 RepliesI am using VB.Net/ASP.Net 2008 and I have a solution with 3 projects:
1. DAL
2. BLL
3. MainWebProject
anyways because it's a Web Application Project (not a web project) I had to set it up so I could access the Profile using Imports System.Web.Profile in the MainWebProj but I can only access the profile in that project.
anyways I need to access the Profile in the DAL also, and I figure since I can import the Profile in my MainWebProj there must be a way to also import that into the sister project, DAL.
My Issue: I can import a class in Project A but not Project B. Is there import syntax so I can also import the namespace in Proj B?
i'm trying an example by trying to creating two projects in one solution to seperate logic and UI. so let's say test.logic and test.ui
in test.ui i have a page called lets say contact me. in the code behind for this page i want to call a method that belongs in a class called processData in test.logic
in contact me cs i tried something like:
namespace test.ui
{
using test.logic
//code here
}
but that does not work as class/method not shown in intellisense.
I am trying to deploy my C# based ASP.Net 3.5 webapp
The hosting service provider said "Access 2003 (.mdb) file has to be put in 'access_db' folder in root folder"
I am currently using
OleDbConnection myConn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + Server.MapPath("~/access_db/filename.mdb"));
The folder structure is like
ParentFolder/access_db/filename.mdb
ParentFolder/ProjectFolder/<Project files> (App_Data, bin, *.aspx, web.config)
1) I am using a GridView on another page that doesn't allow to connect to a database outside the project folder. What should I do?
2) How do I modify the programmatic connection string ( shown above) ?
I have an ASP.Net website, "MyApp", which contains the following resources files:
WebResources.resx
WebResources.es.resx
The website references a library project, "MyLib" from which I want to access those resources files. Here is the code I'm attempting:
var rm = new ResourceManager("MyApp", Assembly.GetExecutingAssembly());
subject = rm.GetString("HelloMessage"); //always string.empty
The problem is that the executing assembly is always "MyLib" instead of "MyApp". Is it possible to access the resource files embedded in the website project from a library project?
recommend a data access class / helper class for Access databases, similar to the sqlhelper class found in the (Data Access Application Block)?
View 6 RepliesI've an XML file stored in App_Data which is only used to read some configuration on startup. When I attempt to open it within my code, I get an Access to the path ... is denied message.
I'm having trouble understanding why, and how to solve it. I guess in theory I should alter the permissions on the file (and directory), but this hasn't changed anything.
To give a bit more background:1. Its a file bundled with the project, so the setup created by VS2008 writes it to the correct place during install. I didn't think I'd need to do anything unusual post install such that the ASP.NET application would have access.
2. When I've tried publishing this locally, I've not had any problems. - This is only on a test Windows 2003 server.
3. I've ran a simple page to understand the effective user of IIS - It is NT AUTHORITYNETWORK SERVICE. I tried granting "Full Access" to this user to this file, and still it doesn't work.The code to open it is simple:
FileStream fs = new FileStream(Server.mapPath(s), FileMode.Open);
Where s is defined as '~/App_Data/myfile.xml
I've even copied and pasted the full path & filename (from the exception) and tried "dir" on it, and it is indeed present (to get around a typo for example).I've also tried running aspnet_regiis.exe /s

I have an ASP.NET web site project where I am using both VB.Net and C# class files. I have included separate sub folders in the App_Code directory for classes of each language.However, while I can successfully make use of a C# class in a VB class, I cannot do the opposite: use a a VB class in a C# class.
So, to illustrate, I might have two classes such as this:
Public Class VBTestClass
Public Sub New()
End Sub [code]....
I get an error that "the type or namespace "VBTestClass" could not be found". What am I missing here?

View 6 RepliesI have created an App_Code folder in my MVC 2 project and added a C# Class to it. In my Controller I have added a using reference to the namespace my class is in so that i can create an instance. However when I run the project it says there is a build error and that the namespace could not be found or doesn't exist. I have added a namespace to the <pages><namespaces> part of the config file and that didn't fix it.
