Our solution is built on ASP.NET v1.1 framework. User is presented with login form, so upon providing credentials this information is posted back to the server. Upon postback SessionID changes and our application crashes as some information which is required for processing is stored in the cache and is identified by SessionID string as a part of the name.
This SessionID change happens absolutely randomly and only to some of the clients. Most of the time browser used to view the page and post info is IE8. I cannot reproduce this issue in our test environment, as SessionID is persistent though-out the whole testing process.
I've already checked all solutions, i.e.
Session cache is used on Page_Load to retrieve/store some information, so it's initialized and contains data stored. I've made a Health Monitoring check on Application_End event to capture any possible AppDomain crashes using Reflection and Diagnostics Libraries and retrieving ShutDownMessage from httpruntime object, but that's also not a case. Cookieless attribute of the sessionState in web.config is set to false (using URL to store SessionID is not an option) All MS security and bug fixes are installed on the server. IIS Server settings are similar to the ones we use in Test Environment.
We have an ASP.NET 3.5 application that has been in production for over a year. Our last release was a couple of months ago. We use CSS for styling and application of background images to divs and such. The server is Windows 2003 with IIS.
Suddenly, this week, we have had reports from some users that the page seems to hang up while loading. The status bar was showing the name of a background image used in the page main area (assigned in CSS). At our office, some of us could recreate the problem, while others could not. IE6 and Firefox do not seem to be affected, only IE7/8. Running Fiddler on an affected machine and trying to see what was happening with the requests seemed to make the problem go away (while running through Fiddler, it returned when not). Hitting Refresh on a hung load often made the page load just fine.
I checked the background image, and even replaced it with an archived copy. No joy. We re-deployed the app from our production source. No Joy. We restarted IIS and eventually rebooted the whole server. There are no unusual entries in the event logs, the app logs or the IIS logs. Finally, I removed the image entirely and re-styled the page not to use a background image. That solved the problem at least for now.
However, we have reports of other images "hanging." The images are PNGs, but I have heard some rumors that sometimes a GIF hangs, but I have no screenshot to confirm.
This just started happening "out of the blue." There have been no releases or updates applied to the server recently. We even checked updates on clients to see if a recent Windows Update might have caused this on the client, but there was nothing updated within the last couple of weeks.
I have a very strange issue, I'm using System.Data.SqlClient. to get data from a SQL Server though a stored procedure. When I test the Application at the Development and Stagging machines it works fine but when I deploy the application on the Production Server I randomly getting an SqlDataReader IndexOutOfRangeException with different column names!.The error appears in 2 requests in each 1000 request (approximative).

I am working on a project at work and have been trying to implement the modalpopup extender. I have it set to display when invalid criteria is entered and the user tries to save the item. The problem that happens is that it will display correctly for about the first 3-5 times, but then after that the entire popup (messagebox/background) displays behind the content behind all the content, which are within panels. I have tried changing the z-index amongst the popup to something really high and keeping the panels' z-index very low, yet it still does not seem to work.
I got a master page with a server control in it. Randomly the server control is inaccessible from codebehind. This doesn't happen on a specific action (eg a Button click or so). Currently I have no clue what this could be. I don't think it's output caching since this is not explcitly activated and the error happens far to seldom for that. But I'm going to disable caching in the master page explicitly with next deployment.
The control is defined in markup. The accompaning codebehind is:
PGFMainNavi.HasAccessToFunction = HasAccessToNaviItem; // HasAccessToNavi is a local function
Exception is:
System.NullReferenceException: Object reference not set to an instance of an object
ffmpeg feels like its taking a long time. I then look at my output file and i see it stops between 6 and 8mbs. A fully encoded file is about 14mb. Why does ffmpeg stop? My code locks up on StandardOutput.ReadToEnd();. I had to kill the process (after seeing it not move for more then 10 seconds when i see it update every second previously) then i get the results of stdout and err. stdout is "" stderr is below.
The output msg shows the filesize ended. I also see a drop in my CPU usage when it stops. I copyed the argument from visual studios. CD to the same working directory and ran the cmd (bin/ffmpeg) and pasted the argument. It was able to complete.
NOTE: I must get std out and err to check for failures.
int soundProcess(string infn, string outfn) { string aa, aa2; aa = aa2 = "DEAD"; var app = new Process();
how to regenerate a new Session ID in ASP.NET. If we are using SessionManager to generate a new id then it doesn't change the value of Session.SessionID. how this can be achieved. Basically I want to have a new Session.SessionID after abandoning Session or generating NewID with SessionManager.
I have a FileUpload control that currently uploads pics to the Photos folder on my server. What I would like to know is how would I give it a randomly generated filename when it gets uploaded? As I don't want duplicates later on down the line. Cheers.(Code below).
I have a aspx content page which is associated with a master page. In the code behind of the master page there have code to populate menu control. Besides the menu there is an AJAX Accordion cotrol which is also binding. In the master page there have n number of javascripts written which are being used in master page and also in the content pages.
In the content page n numbers of functionalities are there. Some times I noticed that the textboxes of the content page is getting disabled randomly. Suppose I have perfomed a task in the page and after that I have seen that the textboxes are disabled but later I have performed the same task and it didn't happen, means the problem is arising randomly.
Onething I want to mention here whenever I am mouse clciking on the textboxes when the textboxes are disabled, nothing happens. Neither the any text being selected nor the mouse pointer is showing (textbox doesn't get focus) but after mouse clicking on one of the textbox if I try to type something the letters are coming in the text box without the letter which I first typed and in the meantime all the textboxes are getting enable again.
I set up forms authentication in my asp.net application, and everything works apparently without problems. However from time to time some of the users trying to log in inform me that suddenly they cannot enter anymore as their user seems to be deactivated. Even if they try the forgot password entry, they get "user not found" response, but if I check the user is still there, and according to asp.net configuration it is even active.The only solution I found until now to reactivate the user is to remove it and create it again, and then it works. But it cannot work like this of course.

if there is a way to dynamically change the session ID from the context of a SessionStateStoreProvider (or some other customizable module) in C# for ASP.NET.
I am implementing a custom SessionStateStoreProvider, and I was thinking about augmenting the session ID to tell the store provider where to go look for a session. I've implemented a custom SessionIDManager, which lets me augment newly created session IDs with the required tag. The problem is that the desired value of that tag might change during the life of a session. For example, the session may be read from one location, but may need to written to a different location. In this instance the ID would have originally been tagged for location A, but on writing the store would want to write to location B. The tag should be updated to reflect location B for the next session read.
So, from the context of SessionStateProviderBase override...
... is it possible to change the session ID? I know that the HttpContext.Session.SessionID property is not settable. Is there some other way to feedback an update like this? Or is there a more appropriate to carry state like this across calls?

I have a problem in collapsiblepanelextender (CPE), prolong i am searching one, ie. i have four collapsiblepanel with four radiobuttons, i select ratiobutton in random if i select one other CPE must be collapse
I have an ASP.NET page that has a wizard control. I need to see if the same user is working on the page so I first time I insert a record and next time I update database records. I am using Session.SessionID to check if the same user is working on the page, but on every postback, SessionID gives a unique string and always the "insert" construct executes.
What is the best way to check the same user is working back and forth on the same page. User is not logged in, its an open form on the page.
