  • Asp Dot Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea?

  • Kernel error causing cpu to go into shutdown state

    - by EpsilonVector
    What kind of Kernel error can cause the cpu to go into a shut down state? I'm doing a homework assignment in OS, and we did changes in sched.c (adding a new scheduling policy, which involved ading another prio_array to the queue and switching between them when needed). Processes using this policy cause the cpu to enter a shut down state when they finish. Any suggestions where to look?

  • Persistence scheme & state data for low memory situations (iphone)

    - by Robin Jamieson
    What happens to state information held by a class's variable after coming back from a low memory situation? I know that views will get unloaded and then reloaded later but what about some ancillary classes & data held in them that's used by the controller that launched the view? Sample scenario in question: @interface MyCustomController: UIViewController { ServiceAuthenticator *authenticator; } -(id)initWithAuthenticator:(ServiceAuthenticator *)auth; // the user may press a button that will cause the authenticator // to post some data to the service. -(IBAction)doStuffButtonPressed:(id)sender; @end @interface ServiceAuthenticator { BOOL hasValidCredentials; // YES if user's credentials have been validated NSString *username; NSString *password; // password is not stored in plain text } -(id)initWithUserCredentials:(NSString *)username password:(NSString *)aPassword; -(void)postData:(NSString *)data; @end The app delegate creates the ServiceAuthenticator class with some user data (read from plist file) and the class logs the user with the remote service. inside MyAppDelegate's applicationDidFinishLaunching: - (void)applicationDidFinishLaunching:(UIApplication *)application { ServiceAuthenticator *auth = [[ServiceAuthenticator alloc] initWithUserCredentials:username password:userPassword]; MyCustomController *controller = [[MyCustomController alloc] initWithNibName:...]; controller.authenticator = auth; // Configure and show the window [window addSubview:..]; // make everything visible [window makeKeyAndVisible]; } Then whenever the user presses a certain button, 'MyCustomController's doStuffButtonPressed' is invoked. -(IBAction)doStuffButtonPressed:(id)sender { [authenticator postData:someDataFromSender]; } The authenticator in-turn checks to if the user is logged in (BOOL variable indicates login state) and if so, exchanges data with the remote service. The ServiceAuthenticator is the kind of class that validates the user's credentials only once and all subsequent calls to the object will be to postData. Once a low memory scenario occurs and the associated nib & MyCustomController will get unloaded -- when it's reloaded, what's the process for resetting up the 'ServiceAuthenticator' class & its former state? I'm periodically persisting all of the data in my actual model classes. Should I consider also persisting the state data in these utility style classes? Is that the pattern to follow?

  • JQuery not copying state dropdown list 1 to DDL2 on checkbox change

    - by user1001411
    I've looked at similar posts on the subject but none of the recommended solutions have worked for me so I'm not sure where I'm going wrong. I have a billing and shipping address form with a dropdown list for the state. Upon checking/unchecking the "billing address same as shipping" everything copies over except the state dropdown list. The state dropdown list is populated from a SQLDataSource state table. Here's my code: <script type="text/javascript" language="javascript" src="../Scripts/jquery-1.4.1.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $('input:checkbox[id*=chkCopy]').change(function () { if ($(this).is(':checked')) { $('input:text[id*=TextBox5]').val($('input:text[id*=TextBox1]').val()); $('input:text[id*=TextBox7]').val($('input:text[id*=TextBox2]').val()); $('input:text[id*=TextBox9]').val($('input:text[id*=TextBox3]').val()); $('input:text[id*=TextBox12]').val($('input:text[id*=TextBox4]').val()); $('select#DropDownList6').val($("select#DropDownList1").val()); $('input:text[id*=TextBox14]').val($('input:text[id*=TextBox6]').val()); } else { $('input:text[id*=TextBox5]').val(''); $('input:text[id*=TextBox7]').val(''); $('input:text[id*=TextBox9]').val(''); $('input:text[id*=TextBox12]').val(''); $('select#DropDownList6').val(''); $('input:text[id*=TextBox14]').val(''); } }); }); and here is my SQL for the DDL: <asp:DropDownList ID="DropDownList1" runat="server" DataTextField="Descr" DataValueField="ID" DataSourceID="SqlDataSource1" Width="254"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString1 %>" SelectCommand="SELECT * FROM [xrefState]"> </asp:SqlDataSource> the other one: <asp:DropDownList ID="DropDownList6" runat="server" DataTextField="Descr" DataValueField="ID" DataSourceID="SqlDataSource5" Width="254"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource5" runat="server" ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString1 %>" SelectCommand="SELECT * FROM [xrefState]"> </asp:SqlDataSource>

  • Maintain state of an ASP.NET page

    - by user279521
    Hi, what is your preferred method to maintain state of an asp.net page, if it is a public website (involving shopping cart, wish-list etc). I am in the process of designing a website that will need to ensure that the user is not able to tamper with the state (such as delete cookies etc).

  • Remember JVM state before executing a specific instruction.

    - by user559064
    I am working on a testing project using mutating technique. My project requires to manipulate a Java classfile and re-execute the classfile multiple times for testing. My implementation need to re-execute the whole system again after one manipulation, and that is not efficient. I am wondering whether I can save the JVM state right before executing a desired instruction in the classfile, so that I can start from that state after each manipulation. Thank you.

  • Filesystems for webserver with SATA and Solid State disk,

    - by Jorisslob
    We have just ordered a new webserver with 120 Gb solid state disk and a SATA disk. I am trying to plan ahead what sort of filesystem to use. This system will be running Linux, Apache/Tomcat to host java services. The main service is a system where people can upload reasonably large files (in the order of 100 Mb, images, image stacks and video), which people will be able to annotate and which will be sent to a database server when annotation is complete. Thus far, I plan to put most of the utility programs of the operating system om the SSD and put the large media files there. The SATA disks will hold the less volitile data like apache, tomcat and the servlets. For filesystems I have considered going for the stable EXT3 because I hear that it is best supported. The downside seems to be that it not the ideal choice for large files. That is why I am leaning towards using XFS for the SSD and EXT3 for the SATA. My questions are: 1) Does this sound like a reasonable setup? 2) What filesystems would you recommend for the SSD and for the SATA? Thanks

  • Computer loses all installed programs and appears to return OS-only state

    - by Jake
    This is a story regarding 3 laptops of different brand and models. On separate occassions, I configured each of these Windows 7 / Vista computers with the necessary configuration and applications (which are supposedly the same actually), e.g. join office domain, same windows updates, microft office etc. These machinese were configure in our office in Singapore, and then they were taken to India for use. Someday in India, when booting up the laptop, all went fine except when it reach the log in screen, it was no longer possible to login with domain credentials. Logging into the laptop local admin account will lead to discover that the machine has returned to "OS-only state". All the configurations and applications were gone. The actual user profiles are still in the C: drive so files can still be retrieved, but under Control Panel Uninstall Programs it is evident that at least the registry is corrupted. The above scenario happen to the first 2 laptops. For the third, the system reports "Operating System Not Found" on boot up. I cannot think of any reason except to suspect a power fluctuation issue. Question is, will a power issue create this behaviour? What else can cause this issue?

  • Mysql queries stuck in "sending data" state

    - by MarkPW
    I'm running a Litespeed web server and a database server (2 x Clovertown 5335) with MySQL 5.1.52-log (running on Cent OS 4.5 and 4.6 32bit respectively). Last week, I upgraded from 5.0.51a-community-log and since then I've been having a problem whereby my database server's load starts increasing for no apparent reason. Running SHOW PROCESSLIST; I see all of my SQL_CACHE queries that use a wildcard in WHERE, backing up and getting stuck in "sending data" state. However, other queries that use SQL_CACHE but no wildcard do not get caught up in this. To get things going again, the first time it happens (after about 24 hours), I have to restart mysql. 4/5 times it will re-occur after about 20 minutes or so and this time and for subsequent occurrences it is not necessary to restart mysql. Simply stopping the web server for a few minutes will suffice while I allow the stuck queries to clear themselves up. I had no such problem with the the previous mysql install. What could be causing the issue and how do I resolve it? Thanks

  • How to uninstall files and software from a Solid State Drive (SSD)

    - by jasondavis
    I am using a SSD drive just as a main Operation system and software drive. I have a regular spinning disk for data files. I have read that files are not REALLY deleted from a SSD drive when you "delete" them. So here is my situation and hopefully I can get some good advice. Let's say I have Windows 7 Pro x64bit installed on my 80gb Intel SSD. I then have Adobe Photoshop CS4 installed along with 50 other programs installed onto this SSD. I then decide I am done with Adobe Phjotoshop CS4 and want to remove it. I then decide I want to install another version of Adobe Photoshop and a few other software titles. Would I just do the usual, add/remove software from the windows control panel. Or if the software being removed has an "Uninstall" program to run, then run it and uninstall the software? I realize that all this WILL remove the software from Windows 7 but I am wanting to know if there is additional steps that should be taken since it is a solid state drive (SSD)?

  • Cluster Core Resource state of Exchange 2010 DAG

    - by Christoph
    I have two Exchange 2010 servers in a DAG and a witness server to implement mailbox resiliency. The two Exchange servers are in two subnets and the Windows failover cluster therefore has two IP address resources. I now that Exchange uses "core functionality" of Windows Server failover clustering, but it does not use all features. My setup also seems to work, but if I run the validation in the Windows Failover Cluster Manager, it complains about one of the IP address resources being offline. However, I cannot bring this resource online, because the server complains that "the specified cluster node is not the owner of the resource, or the node is not a possible owner of the resource". If I "Simulate failure of this resource", it becomes offline and the other IP becomes online. I have the vague idea that Exchange might use the state of the IP resource to identify the Primary Active Manager, but I am not sure. As it is obviously important that failover really works, I would like to be sure. Therefore, my question is: Is it normal that only one IP address resource in a Exchange 2010 DAG failover cluster is active at a time? If not, how do I bring both resources online at the same time given the error described above?

  • Solid State Drive Occasionally Freezes For A Minute While OS Is "Beach Balling"

    - by Boris_yo
    Almost a month ago I bought Intel 330 128GB solid state drive, migrated my data with Intel branded limited-feature Acronis from old HDD to new SSD, optimized with Intel Toolbox and started using it. Occassionally I get close to 1 minute freezes while seeing operating system "beach balls" and animations still work, I can interact and click on something but nothing responds, nothing loads. Recently a couple of such freezes occurred in shorter amount of time in a row. I have noticed that if I stop interacting with laptop, the freeze lasts less time than if I was interacting with laptop. But the bigger problem is when freeze just does not end and computer keeps being stuck unlil it is more than half hour and I run out of patience to keep waiting and feeling I need to restart the system because I am not getting anywhere. Such freeze happened while laptop was cold booting into Windows 7. This is when freeze hang occurred and I had to restart, only later to be greeted with Windows recovery screen stating something about faiure of boot sector and asking to insert Windows repair CD. But after I restarted, Windows booted successfully and all was well. I have filmed video of freeze hang occurring in cold boot which you can see here (on video page look below for description): http://www.youtube.com/watch?v=8b7MQlcDTUs As I have mentioned in the beginning, the SSD is less than a month old but here is S.M.A.R.T statistics just in case (TRIM is enabled btw according to CrystalDiskInfo): I want to emphasize that this SSD is the only drive I have, yet it is working in RAID mode (it was enabled initially in BIOS by previous laptop's owner) on Intel Rapid Storage drivers. I am contemplating about switching to AHCI mode but want to be sure this won't cause data loss. Additionally, the stock firmware is the only firmware available currently, yet Intel does not respond to my posts in their community board. If anyone here has this SSD model or generally has experience with SSD drives, I would love to know your thoughts.

  • Hadoop streaming job on EC2 stays in "pending" state

    - by liamf
    Trying to experiment with Hadoop and Streaming using cloudera distribution CDH3 on Ubuntu. Have valid data in hdfs:// ready for processing. Wrote little streaming mapper in python. When I launch a mapper only job using: hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar -file /usr/src/mystuff/mapper.py -mapper /usr/src/mystuff/mapper.py -input /incoming/STBFlow/* -output testOP hadoop duly decides it will use 66 mappers on the cluster to process the data. The testOP directory is created on HDFS. A job_conf.xml file is created. But the job tracker UI at port 50030 never shows the job moving out of "pending" state and nothing else happens. CPU usage stays at zero. (the job is created though) If I give it a single file (instead of the entire directory) as input, same result (except Hadoop decides it needs 2 mappers instead of 66). I also tried using the "dumbo" Python utility and launching jobs using that: same result: permanently pending. So I am missing something basic: could someone help me out with what I should look for? The cluster is on Amazon EC2. Firewall issues maybe: ports are enabled explicitly, case by case, in the cluster security group.

  • Mysql connections hanging in login state

    - by Mark Rose
    Suddenly today, I had an issue with connections to mysql hanging when connecting by IP address (e.g. mysql -h 10.1.248.20), but I could still connection using localhost fine, regardless the user. mysql> show processlist; +----+----------------------+------------------+------+---------+------+-----------------------------------------------------------------------+------------------+ | Id | User | Host | db | Command | Time | State | Info | +----+----------------------+------------------+------+---------+------+-----------------------------------------------------------------------+------------------+ | 1 | system user | | NULL | Connect | 10 | Connecting to master | NULL | | 2 | system user | | NULL | Connect | 10 | Has read all relay log; waiting for the slave I/O thread to update it | NULL | | 37 | unauthenticated user | 10.1.248.3:36694 | NULL | Connect | NULL | login | NULL | | 38 | unauthenticated user | 10.1.248.3:36695 | NULL | Connect | NULL | login | NULL | | 39 | unauthenticated user | 10.1.248.3:36696 | NULL | Connect | NULL | login | NULL | | 40 | root | localhost | NULL | Query | 0 | NULL | show processlist | +----+----------------------+------------------+------+---------+------+-----------------------------------------------------------------------+------------------+ 6 rows in set (0.00 sec) Yes, I realize replication was broken in that output above; that was after I tried restart MySQL (it was an emergency). And as suddenly as things stopped working, they started working again. DNS was working fine at the time. Replication was still working. MySQL was responsive. Does anyone have any idea what would cause MySQL logins from remote IPs to hang suddenly?

  • PHP regex to search across multiple lines

    - by Gaz
    I'm using preg_* in PHP to search for the pattern <!-- %{data=THIS GETS MATCHED}% --> and pull out the matched text. The pattern for this is: preg_match('#<!-- %{' . $knownString . '\s*=\s*(.*?)}% -->#', ...) What I would like it to do is search across multiple lines for the string. For example: <!-- %{data= THIS GETS MATCHED AND RETURNED }% --> How can I edit my current pattern to have this search ability?

  • GridView doesn't remember state between postbacks

    - by Ryan
    Hi, I have a simple ASP page with databound grid (bound to an object source). The grid is within the page of a wizard and has a 'select' checkbox for each row. In one stage of the wizard, I bind the GridView: protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e) { ... // Bind and display matches GridViewMatches.EnableViewState = true; GridViewMatches.DataSource = getEmailRecipients(); GridViewMatches.DataBind(); And when the finish button is clicked, I iterate through the rows and check what's selected: protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e) { // Set the selected values, depending on the checkboxes on the grid. foreach (GridViewRow gr in GridViewMatches.Rows) { Int32 personID = Convert.ToInt32(gr.Cells[0].Text); CheckBox selected = (CheckBox) gr.Cells[1].FindControl("CheckBoxSelectedToSend"); But at this stage GridViewMatches.Rows.Count = 0! I don't re-bind the grid, I shouldn't need to, right? I expect the view-state to maintain the state. (Also, if I do rebind the grid, my selection checkboxes will be cleared) NB: This page also dynamically adds user controls in OnInit method. I have heard that it might mess with the view state, but as far as I can tell, I am doing it correctly and the viewstate for those added controls seems to work (values are persisted between postbacks) Thanks a lot in advance for any help! Ryan UPDATE: Could this be to do with the fact I am setting the datasource programatically? I wondered if the asp engine was databinding the grid during the page lifecycle to a datasource that was not yet defined. (In a test page, the GridView is 'automatically' databound'. I don't want the grid to re-bound I just want the values from the viewstate from the previous post! Also, I have this in the asp header: ViewStateEncryptionMode="Never" - this was to resolve an occasional 'Invalid Viewstate Validation MAC' message Thanks again Ryan

  • Integration tests in Continuous Integration environment: Database and filesystem state

    - by dario_ramos
    I'm trying to implement automated integration tests for my application. It's a very complex monster. You could say that its database and part of the filesystem are part of its state, because it saves image files in the hard drive, and references to those in the DB. The software needs all those, in a coherent state, to work properly. Back to writing tests: To run any relevant test, I need some image files in the filesystem, and certain records filled in the database. I thought of putting all of these in a separate folder called TestEnvironmentData in the repository, and retrieving them from the Continuous Integration Server (Team City), but a colleague said the repo is quite full as it is, and that I should set up a special directory, and databases, only in the Continuous Integration server. I don't like that because the tests success depend on me manually mantaining stuff in the server, and restoring initial state before every test becomes cumbersome. What do you guys do when you need to write integration tests for an app like this? The main goal is having an automated test harness to approach a large scale refactoring. There's lots of spaghetti code and the app's current architecture is hardly unit testable, that's why I decided on integration tests first. Any alternative approach is welcome.

  • JQUERY: Setting Active state on animated menu tabs

    - by Tony
    I have image sprites that use JQuery to set the BG position on mouseover and mouseout events. When I set the active state BG position using JQUERY it works fine until I move my cursor away from the active 'tab' which then fires the mouseout event animation. What I want is the mouseClick event to stop the animation on the active tab but still allow the animation effect to work on the other tabs, and when another tab is clicked for the active state to be removed from the current tab to the new 'active' tab. JQuery $(function(){ /* This script changes main nav links hover state*/ $('.navigation a') .css( {backgroundPosition: "-1px -120px"} ) .mouseover(function(){ $(this).stop().animate({backgroundPosition:"(-1px -240px)"}, {duration:400}) }) .mouseout(function(){ $(this).stop().animate({backgroundPosition:"(-1px -120px)"}, {duration:400, complete:function (){ $(this).css({backgroundPosition: "-1px -120px"}) }}) }) }); $(document).ready(function(){ $("a").click(function(){ $(this).css({backgroundPosition: "-1px -235px"}); }); }); HTML <ul class="navigation"> <li><a href="#index" tabindex="10" title="Home" id="homeButton"></a></li> <li><a href="#about" tabindex="20" title="About us" id="aboutButton"></a></li> <li><a href="#facilities" tabindex="30" title="Our facilities and opening Times" id="facilitiesButton"></a></li> <li><a href="#advice" tabindex="40" title="Advice and useful links" c id="adviceButton"></a></li> <li><a href="#find" tabindex="50" title="How to find Us" id="findButton"></a></li> <li><a href="#contact" tabindex="60" title="Get in touch with us" id="contactButton"></a></li> </ul> You can see what I've got so far here Thanks in advance for any help

  • desing pattern for related inputs

    - by curiousMo
    My question is a design question : let's say i have a data entry web page with 4 drop down lists, each depending on the previous one, and a bunch of text boxes. country (ddl), state (ddl), city (ddl), boro (ddl), address (txtBox), zipcode(txtbox). and an object that represents a datarow with a value for each. naturally the country, state, city and boro values will be values of primary keys of some lookup tables. when the user chooses to edits that record, i would load it from database and load it into the page. the issue that I have is how to streamline loading the ddls. i have some code that would grab the object, look thru its values and move them to their corresponding input controls in one shot. but in this case i will have to load possible values of country, then assign values, then load values of state, then assign value ans so on. I guess i am looking for an elegant solution. i am using asp.net, but i think it is irrelevant to the question. i am looking more into a design pattern. thanks
