I am running a Silverlight 1.1 application developed in July, just before loading the page error 'WPF/E installed on your system is no longer valid' is thrown.
Then I uninstalled SilverLight 1.1 Alpha and installed Silverlight.1.1.AlphaRefresh, but then also it is not working. Silverlight.1.1.AlphaRefresh is released for IE 6 and 7 on Windows SP2 and Windows Vista. But OS in my system is Windows 2003 Server. Can anyone help me in fixing the issue.

Thanks,

Still your question is not clear. Are you asking about, what will happen if two users requested at same time ?

Sorry still not clear with your question. Assume i looged into Site1 with user name and password, and I also logged into Site2 with other user name and password. What do you mean by pass 2 request to server? Which server you will pass? How you will get these details since both are in two different sites ?

Make me clear that, are you maintaining two accounts in one site or different site's ?

How to combine two applications in one application

For the admin rite ? Who wants to see the results of how many users logged in ? You have some events in Global.asax. In application_start event you start one application variable that holds each session count. In session_start event increment this count. Printing application variable value will give you total number of active sessions.

To retrieve details of that account, you need to store userid also in application variable. I presume that you have a unique userid to identify each user.

Problem writing Cookie

Hi Guru's

I'm having problem on writing cookie, not on the code but I can't seem to find the actual cookie file that was created, I also tried to placed the cookie path to my project folder but I still can't seem to find the cookie that was created. Below is my code for creating cookie.

Am I doing something wrong?

Please advice

<br />
    Dim bcap As HttpBrowserCapabilities<br />
        Dim bookmarkCookie As HttpCookie<br />
        bcap = Request.Browser<br />
<br />
<br />
        If Not bcap.Cookies = True Then<br />
            wc_header.setError("Cannot bookmark page, Cookie is not enabled in this browser")<br />
            Return False<br />
<br />
        Else<br />
            bookmarkCookie = New HttpCookie("pageBookmark")<br />
            bookmarkCookie.Path = Server.MapPath("../")<br />
            bookmarkCookie("pageID" & pID) = CType(pID, String)<br />
            bookmarkCookie.Expires = Now.AddDays(1)<br />
            Request.Cookies.Add(bookmarkCookie)<br />
<br />
            Return True<br />
<br />
        End If<br />
<br />

Cookies are saved in special folders on users computes and you cannot change this (well, you can if you change the registry settings on every machine for the cookies folder). The usual folder in which cookies are saved is [WINdrive]:\Documents and Settings\[user name]\Cookies

Thanks Mircea,

I tried looking on the path you suggested but there seems to be no cookie folder, I also tried viewing hidden folders but still no luck, I don't know if its on the code although writing cookie is pretty straight forward.

Mircea Grelus2-Aug-07 19:24

Yes, adding a cookie is straightforward. You just have to add it to the request.
I noticed you are setting the Path property to your cookie. The path describes the url to which the cookie applies. The best thing to do is set the cookie from a page in the root folder and remove the Path property from your code.

Mircea

Hmm the path points to where the cookie will be created
bookmarkCookie.Path = Server.MapPath("../")

I replaced it to more a specific location but nada.. no cookie Frown | :(

bookmarkCookie.Path = Server.MapPath("../_cookies")

What do you mean by Set the cookie from a page in the root folder are you suggesting that I should place the page that writes cookie to the root?

Please advice

NO.
The Path property indicates the path for which the cookie will be created. (path in your website structure)

Either place the page in teh root or place the code that creates the cookie in a page from the root.

And remove the Path property from your code.

I just place the page where calls the writing of cookie file, also I removed the path location, but no cookies was generation on the root folder. Does the page needed to be on a live webserver to generation cookies? or does this run on local web instance?

huhu..

No. Cookies are generated on localhost as well.

You just don't get it. Cookies are generated in SPECIAL FOLDERS according to the type of browser you use. Not in your website. The browser that you use decides where it stores them.
Use this tool[^] to find the path where the cookie is generated if you use Internet Explorer as the browser.

Session Variables and WebServices

2-Aug-07 22:42

Thank you for the help Mircea,

I've been using firefox sorry for that, I downloaded the app that you've gave and run the cookie page on IE browser. I checked on my cookie folder (that was shown on special folder location app) but can't find the cookie I created. To make sure I run a cookie checking script to see if there was a cookie generated, but it skipped the condition which means no cookie was created, below is my code:

  pageBookmarkcookie = Request.Cookies("pageBookmark")<br />
        If pageBookmarkcookie IsNot Nothing Then<br />
<br />
            For x As Integer = 0 To pageBookmarkcookie.Values.Count - 1<br />
               Response.Write(pageBookmarkcookie.Values(x))<br />
<br />
            Next<br />
         else<br />
            response.write("no cookie found")<br />
<br />
        End If

I have a Session variables which i want to expose in a WebService.

Web Application:

Session["myObject"];

WebService:

    [WebMethod(EnableSession = true) ]
    public SuperSession GetSuperSession(string UserName)
    {
        List<object> ListOfObject = (List<object>)Session["myObject"];

        return ListOfObject;
    }

When I do this, i get the following error:

To be XML serializable, types which inherit from ICollection must have an implementation of Add(System.Object) at all levels of their inheritance hierarchy. System.Web.SessionState.HttpSessionState does not implement Add(System.Object).

I have tried serializing the Global object with noluck.

Any ideas?

Thanks in advance!

I feel that, you won't be able to share session created by webapplication in webservice. Instead of doing this, why don't you pass your serializable class object to webservice method directly ?

Hi,
I made a windows software for one of my client and the windows software used to do long task in background thread, Now he wants me to implement the same thing as ASP.NET Web application. I am afraid if it is really possible in ASP.NET to implement background worker thread as I know ASP.NET request has limited time allowance and after that time, the request is killed. Would you please let me know any idea.

Regards

You can set the Script.Timeout value to some arbitrarily high number at the start - just warn them that they must not navigate away or close their browsser until it is finished. (They can always open another tab if they want...)

And/or you can experiment with this
http://www.xmlx.net/software/2005/08/anatomy_of_a_pr.html[^]

to give them something to look at while it's happening...
