What you want is

HttpContext.Current.Profile

Elvin replied to Anoop S on 08-Oct-11 07:55 PM

I am new to building a shopping cart. where exactly does HttpContext.Current.Profile goes or in other words where do I add it? Is it in the same page or in the web.config file?

my web config file is as follows:

Changed only to this:

//ProfileCommon anonymousProfile = Profile.GetProfile(e.AnonymousID);

ProfileCommon anonymousProfile = (anonymousProfile)HttpContext.Current.Profile;

But i get the same error as before where Profile is not found in current context plus these two others:

Error 1 The type or namespace name 'ProfileCommon' could not be found (are you missing a using directive or an assembly reference?) C:\Users\CyBeRfOrCe\Documents\Visual Studio 2008\Projects\zephyrAir2\Global.asax.cs 54 13 zephyrAir2

Error 2 The type or namespace name 'anonymousProfile' could not be found (are you missing a using directive or an assembly reference?) C:\Users\CyBeRfOrCe\Documents\Visual Studio 2008\Projects\zephyrAir2\Global.asax.cs 54 47 zephyrAir2

Anoop S replied to Elvin on 09-Oct-11 01:16 AM

Turns out that Web Applications don't support the auto generation of the ProfileCommon object like web site projects do. To get this to work install http://code.msdn.microsoft.com/WebProfileBuilder and then add it to the build process as described http://weblogs.asp.net/joewrobel/archive/2008/02/03/web-profile-builder-for-web-application-projects.aspx.

Elvin replied to Anoop S on 09-Oct-11 09:19 AM

Do I have to store it in a folder of Visual Studio 2008? If so, which one?

dipa ahuja replied to Elvin on 09-Oct-11 09:31 AM

1. Enable the profile in web.config

<profile enabled="true">

2. Add the namespace :

using System.Web.Profile;

Done!

Hi Elvin,

I think you've not imported the namespace the Profile class is in. suppose if the Profile class is under namespace "MyNamespace" import it to your page as well like

using MyNamespcae;

Elvin replied to dipa ahuja on 09-Oct-11 11:52 AM

I added it already before you posted and I get the same error:

I added this:

<system.web>

</authorization>

</system.web>

<system.web>

I also added this to the Global.asax.cs:

using System;

using System.Collections;

using System.Configuration;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Security;

using System.Web.SessionState;

using System.Xml.Linq;

using System.Web.Profile;

<add name="SCart" serializeAs="Binary"

type="zephyrAir2.Cart"

allowAnonymous="true"/>

</properties>

</profile>

</system.web>

dipa ahuja replied to Elvin on 09-Oct-11 12:27 PM

have you added the namespace ?

using System.Web.Profile;

If yes then post the error what you are getting. We understood where you are getting error but what error you are getting post that

I am making a school project with team that barely does something or code.
