Re: Unable to serialize the session state - ASP.NET v2.0 -- Please Help

amissra — Wed, 25 Nov 2009 14:43:19 GMT

Hi,

Thanks for replying. I've read that post before, and that doesn't really help. I have "StateServer" in the web.config file, and I've been told to leave it as that. I can't go to "InProc", which is why I mentioned that earlier.

Unable to serialize the session state - ASP.NET v2.0 -- Please Help

amissra — Wed, 25 Nov 2009 14:15:58 GMT

Hi, I'm a little new to asp.net and I'm not exactly sure how to tackle this problem.....

On the web application we're using, I'm essentially trying to print out data from a repeater in a panel out to a printer. In the web.config, we're using "StateServer" as the Session State.

The data I get for the repeater is from a set of operations I do to a mysql database... ie. a function collects data from a database.... I manipulate records for the database ..... **I keep track of what I manipulated**

The data I keep track of is what I send to the repeater to display a report. This report is what I'm trying to print out to a printer.

Oh, and the data binding for the repeater is done on Page_Load of the page itself.

The error I'm getting is this:

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

I realize that if I change the web.config sessionState control to "InProc", that what I'm trying to do does function.... but that's NOT how the web application was designed... It's specifically designed for "StateServer", and I cannot change that.... also, I further realize that something, is being sent back that is NOT serialized.... according to the stack that is 'System.Web.UI.WebControls.Panel' ....

Any help on this would be much appreciated... I really don't know what to do to fix this...

Registering ASP.net v2.x with IIS5.1 on Windows XP

willow315 — Sun, 15 Nov 2009 22:37:42 GMT

I have read numerous tutorals, and when I attempt to run the following suggested command from the cmd line, my computer tells me it cannot find the specified path....which makes no sense. the path is correct.

%windir%\Microsoft.NET\Framework\vxxxxxx\aspnet_regiis.exe -i

regsvr32 %windir%\Microsoft.NET\Framework\vxxxxxx\aspnet_isapi.dll

of course replacing the vxxxxetc with my v2x number.

Even when I use the complete path starting at c:\Windows...etc.

Why would it tell me that it can't find the path, when the path is correct, and the specified folder is where it's supposed to be. I don't get it.

Any assistance would be appreciated. WCW

Troubleshooting Login Issues

bewA — Wed, 09 Sep 2009 10:28:24 GMT

Hi, i'm hoping you can help me! First off i didn't write the site so i may have to ask one of our devs any code related questions you ask :)

I'm having a problem with our ASP.NET 2 website in IIS6.

Basically what happens is when I open the site I get a login page I type in the details to login and click login and the page just seems to refresh. If I type in the wrong password the site tells me the password is wrong. So something seems to accept my password.

The only way to get this to work is to use localhost in the address e.g. http://localhost/vdirectory

If i use the servers IP or hostname then the login page just refreshes.

There is something specific to the way the IIS server is setup i believe but we have numerous sites with this site installed and it works perfectly fine.

I've checked the log WWW log file and all it says is this:

2009-09-09 09:23:17 W3SVC1349041065 10.0.108.242 POST /StaffPortal/login.aspx - 8181 - 10.0.108.242 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.2;+.NET+CLR+1.1.4322;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.04506.30;+.NET+CLR+3.0.04506.648) 200 0 0

The HTTP status codes don't seem to yeild any clues at all!

Oh and Directory Security is set for anonymous access only.

If someone could give me some things to check I would greatly appreciate it as i'm not sure where to check now!

If there is more info you need just let me know and i'll get it! :)

Thank you in advance!

ASP.NET Application generates different html when accessed though a reverse proxy server

DSMSN01 — Thu, 03 Sep 2009 06:02:38 GMT

I'm accesses the same asp.net 2.0 (IIS 6.0) application in different ways; 1) directly from the browser to the server and 2) via a reverse proxy service that provides access through a firewall. Accessing the exact same page/information using each of these methods produces different html. The reverse proxy method gives me undesirable results. The web page formatting is corrupted. What could cause this? Could there be something in the header that is received from the proxy server that makes IIS behave differently?

sending mail with IIS 7 on 64bit system

jpv2301 — Tue, 18 Aug 2009 12:50:55 GMT

Hello,

I’ve encountered a problem with sending e-mail using the vb.net net.mail class and using the SmtpDeliveryMethod.PickupDirectoryFromIis option. The option SmtpDeliveryMethod.Network works fine.

I’ve made a webappliaction than sends an e-mail. This works great on windows server 2008 on a 32 bits machine but fails on a 64 bits machine. I get the following exception:System.Net.Mail.SmtpException: Cannot get IIS pickup directory. at System.Net.Mail.IisPickupDirectory.GetPickupDirectory() at System.Net.Mail.SmtpClient.Send(MailMessage message)

Is there a setting I can change to get this working on a 64bits system?

IIS hangs when updating aspx files

frank711 — Fri, 14 Aug 2009 11:37:44 GMT

Hello,

our website runs with ASP.NET on IIS 6.0. When we update aspx-files (our content management system transfers files which have been updated with ftp to the server) the IIS doesn't respond to http requests and seems to hang for some time. It needs minutes until a page is loaded, sometimes the event log shows HttpException - Timeout for this request.

I know that the files are compiled when updated and this needs some time, but this shouldn't cause hanging the complete site? I believe that in the past we hadn't this problem.

Anyone got an idea?

Thanks,
Frank

Updating Browser Definition Files

MikeGale — Mon, 20 Jul 2009 00:15:31 GMT

I would like to know what the official position is on updating, browser definition files.

The documentation suggests not changing the *.browser files in machine wide .NET configuration, as service packs etc. can be expected to do that.

I'm interested in the machine wide settings, not settings in an individual web site.

How often are these files updated?

How long after a new browser version is launched can updates be expected?

Where are the updates available?

How to grok current exploits on a IIS (6) server

MikeGale — Fri, 10 Jul 2009 04:06:43 GMT

I code up sites written for ASP.NET 3.5.

They have security built in but I'd like to go further.

I'd like to understand what exploits are currently being used and attempt those on various versions of sites. (Staging and live.)

Having had a quick look at cracker tools, I'd prefer a tech. savvy high level view, and insight from others who've been through this.

What suggestions?

What to do for a rootkit...

rgsnowman — Sun, 14 Jun 2009 13:01:38 GMT

I have recently found a rootkit on my computer through AVG and am wondering how to get this thing off. I tried to get AVG to delete it but it said it cannot. I heard you can re-install windows vista and also restore default settings but I am not sure if that deletes everything and I'll have to get external hd and if the rootkit would get itself into there and I'd be re-installing a rootkit. This rootkit is screwing up my xps one it tiny ways, it changed all my security setting and turned my anti-viruses off and I can't turn them back on, messed up background, screwed up start menu and toolbar, and the side panel. I just want to know the best way to get this off computer. Thanks in advance.
