  • Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

    - by h_power11
    Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

  • Are sessions modifiable by the client/user?

    - by Sev
    In my PHP Web-App I use sessions to store the user's data. For exmaple, if a user logs in, then an instance of the User class is generated and stored in a Session. I have access levels associated with each user to determine their privileges. Store the user in a session by: $_SESSION['currentUser'] = new User($_POST['username']); For example: if($_SESSION['currentUser'] -> getAccessLevel() == 1) { //allow administration functions } where getAccessLevel() is simply a get method in the User class that returns the _accesslevel member variable. Is this secure? Or can the client somehow modify their access level through session manipulation of some sort?

  • Methods for breaking up content client-side into multiple "pages"

    - by Tom Genoni
    I have a long HTML text-only article formatted with paragraph tags. What I'd like to do is break this content into N number of divs so that I can create individual pages. So, for instance, on an iPad/iPhone, instead of reading one long page the user could swipe right/left to navigate to pages. My initial javascript attempts have been somewhat convoluted: creating an array of the text, measuring line-heights, device window heights, adding closing/opening paragraph tags and the end/beginning of pages. Thoughts on a good way to approach this? I will not have access to server-side processing, this has to be a client-side solution.

    - by Mini
    We have recently installed Team Explorer client for 2005 and TFS server 2008.. We have been using VS2005 and VSS earlier. To connect to TFS server 2008 we have installed a hotfix VS80sp1-KB932544-X86-ENU.exe. Everything has been setup well. However I noticed that when the files are checked out and u make some modifications , during checking in resolve confict dialog box asking to merge changes done by others isn't appearing. Instead the file is getting checked in overwriting the changes done by others. Is there some setting that needs to be done on TFS server 2008? Kindly help.

  • Refactoring FAT client legacy application

    - by Paul
    I am working on a fat client legacy C++ application which has a lot of business logic mixed in with the presentation side of things. I want to clean things out and refactor the code out completely, so there is a clear seperation of concerns. I am looking at MVC or some other suitable design pattern in order to achieve this. I would like to get recommendations from people who have walked this road before - Do I use MVP or MVC (or another pattern)? What is/are the best practices for undertaking something like this (i.e. useful steps/checks) ?

  • Client Side Only Cookies

    - by Mike Jones
    I need something like a cookie, but I specifically don't want it going back to the server. I call it a "client side session cookie" but any reasonable mechanism would be great. Basically, I want to store some data encrypted on the server, and have the user type a password into the browser. The browser decrypts the data with the password (or creates and encrypts the data with the password) and the server stores only encrypted data. To keep the data secure on the server, the server should not store and should never receive the password. Ideally there should be a cookie session expiration to clean up. Of course I need it be available on multiple pages as the user walks through the web site. The best I can come up with is some sort of iframe mechanism to store the data in javascript variables, but that is ugly. Does anyone have any ideas how to implement something like this? FWIW, the platform is ASP.NET, but I don't suppose that matters. It needs to support a broad range of browsers, including mobile. In response to one answer below, let me clarify. My question is not how to achieve the crypto, that isn't a problem. The question is where to store the password so that it is persistent from page to page, but not beyond a session, and in such a way that the server doesn't see it.

    Currently I run a DNS server (bind9) that handles queries from clients over the internet lately I have noticed hundreds of queries from all different address's that look like this (Server IP removed) client 216.59.33.210#53: query: ripe.net IN ANY +ED (0.0.0.0) client 216.59.33.204#53: query: ripe.net IN ANY +ED (0.0.0.0) client 208.64.127.5#53: query: ripe.net IN ANY +ED (0.0.0.0) client 184.107.255.202#53: query: ripe.net IN ANY +ED (0.0.0.0) client 208.64.127.5#53: query: ripe.net IN ANY +ED (0.0.0.0) client 208.64.127.5#53: query: ripe.net IN ANY +ED (0.0.0.0) client 205.204.65.83#53: query: ripe.net IN ANY +ED (0.0.0.0) client 69.162.110.106#53: query: ripe.net IN ANY +ED (0.0.0.0) client 216.59.33.210#53: query: ripe.net IN ANY +ED (0.0.0.0) client 69.162.110.106#53: query: ripe.net IN ANY +ED (0.0.0.0) client 216.59.33.204#53: query: ripe.net IN ANY +ED (0.0.0.0) client 208.64.127.5#53: query: ripe.net IN ANY +ED (0.0.0.0) Can someone please explain why there are so many clients querying for ripe.net ?

  • Email with extra '.com' behind sender email address

    - by CHT
    Currently I had a situation where I sent an email to [email protected], but when I receive mail from [email protected], it showed as [email protected], with extra '.com' behind the email address, this just happen within this week. Before this, I didn't change any setting, currently I am using Outlook 2010. When I checked the email in webmail, it also showed it as [email protected]. It seem that it has nothing to do with Outlook. However, I also tried on Thunderbird 16.0.1, but still the problem is the same. Has anyone experienced this before? Is the problem caused by the sender or receiver?

  • Can any web-based email program let user paste an image (not link) as part of the email instead of a

    - by Jian Lin
    I think back in the old days, some email programs let users Paste an image right inside the email content. (maybe WinMail or Outlook?) So for example, we can write some text, embed an image, and then write some more text, and embed another image. The recipient will get the email content in the above text-image-text-image order (instead of having all images attached at the end of email) Can any web-based email program do that? Note that the image is not just a link, but a complete file. For example, Gmail lets us paste an image, but it is actually just a link to some web location. Can the actual file content be embedded instead?

  • Thunderbird "undo send" feature (like in Gmail)?

    - by josh
    I was wondering if there exists a thunderbird addon that gives similar functionality as Google's "undo send" feature? This basically just delays the sent message for a few seconds allowing the user to cancel the send if desired. I find this very useful in Gmail and would love the option now that I started using thunderbird. I've seen the send later addon, but this isn't really what I want. I want something very similar to Google's feature where it automatically delays each message before sending with an easy to access option to cancel the send. Thanks!

  • Why is my own e-mail address not listed in the To field?

    - by Sammy
    I have received a suspicious e-mail. I am not affiliated with the company mentioned in the e-mail body, or the signer. However, I have been using the app they mention in the e-mail. They are inviting me to a Beta test. But the e-mail is not by the original author of the app. But I'm thinking they might have hired an external company to do this version of the app. There is a link to a TestFlight page. So I'm not sure what to make of this. Now this is what mainly arose my attention. From: Anders Bergman <[email protected]> To: Bon Support Cc: Subject: Test av nya BBK för Android This is how it shows up in Outlook 2010. The "To" field is addressed to "Bon Support" and when I double-click on that I see [email protected]. I can assure you that none of these are my e-mail addresses. So where the heck is my own e-mail address? How could I have received this if it was addressed to someone else? If not spammers and skimmers and other criminals, who else is using this practice and why? And how can I tell now to what e-mail account I received this? I have more than one account set up in Outlook.

  • FreeNX is very unresponsive compare to VNC when using over LAN

    - by Phuong Nguyen
    I find FreeNX is quite unresponsive compare to VNC when using over LAN. I run Netbeans inside a Quad Core Server and remote desktop to it through both NX & VNC. For VNC, the screen will be nicely updated as I scroll the Netbean IDE For FreeNX, flickering happened and the mouse cursor become unresponsive as I tried to do the samething. Have anyone encountered the same? I don't like VNC because when VNC doesnot correctly understand the "Windows" key (interpreted as Super L instead of Mod) Is there any adjustment that can avoid that annoyance? I have tried both FreeNX-Server and NeatX-Server and both resulted in the same unresponsiveness.

  • Is it possible to aggregate multiple email accounts into a single Outlook 2007 Inbox/.OST file?

    - by Howiecamp
    I'm using Outlook 2007 and would like to combine multiple email accounts (some are Exchange, some IMAP) into a single Inbox/.OST mail file. An example of the functionality I'm looking for is the Blackberry, where you can configure multiple email accounts and then access that mail either by the inbox for that specific account or via a single aggregated mailbox. In the single mailbox case, when you reply to a given piece of mail the Blackberry is smart enough to switch your "From" address to be that of the account where the email came in to. I'm essentially looking for this functionality in Outlook. Are there native options and/or third party plug-ins which do this?

  • Variable size encrypted container

    - by Cray
    Is there an application similar to TrueCrypt, but the one that can make variable size containers opposed to fixed-size or only-growing-to-certain-amount containers which can be made by TrueCrypt? I want this container to be able to be mounted to a drive/folder, and the size of the outer container not be much different from the total size of all the files that I put into the mounted folder, while still providing strong encryption. If to put it in other words, I want a program like truecrypt, which not only automatically grows the container if I put in new files, but also decreases it's size if some files are deleted. I know there are some issues of course, and it would not work 100% as truecrypt, because it basically works on the sector level of the disk, giving all the filesystem-control to the OS, and so when I remove a file, it might as well be left there, or there might be some fragmentation issues that would stop just truncating the volume from working, but perhaps a program can be built in some other way? Instead of providing sector-level interface, it would provide filesystem-level interface? A filesystem inside a file which would support shrinking when files are deleted?

  • ESXI guests not using available CPU resources

    - by Alan M
    I have a VMWare ESXI 5.0.0 (it's a bit old, I know) host with three guest VMs on it. For reasons unknown, the guests will not use much of the availble CPU resources. I have all three guests in a single pool, with the hosts all configured to use the same amount of resource shares, so they're basically 33% each. The three guests are basically identically configured as far as their VM resources go. So the problem is, even when the guests are performing what should be very 'busy' activitites, such as at bootup, the actual host CPU consumed is something tiny, like 33mhz, when seen via vSphere console's "Virtual Machines" tab when viewing properties for the pool. And of course, the performance of the guest VMs is terrible. The host has plenty of CPU to spare. I've tried tinkering with individual guest VM resource settings; cranking up the reservation, etc. No matter. The guests just refuse to make use of the abundant CPU available to them, and insist on using a sliver of the available resources. Any suggestions? Update after reading various comments below Per the suggestions below, I did remove the guests from the application pool; this didn't make any difference. I do understand that the guests are not going to consume resources they do not need. I have tried to do a remote perfmon on the guest which is experiencing long boot times, but I cannot connect to the guest remotely with perfmon (guest is w2k8r2 server). Host graphs for CPU, Mem, Disk are basically flatlining; very little demand. Same is true for the guest stats; while the guest itself seems to be crawling, the guest resource graphing shows very little activity across CPU, Mem, Disk. Host is a Dell PowerEdge 2900, has 2 physical CPU,20gb RAM. (it's a test/dev environment using surplus gear) Guest1 has: VM ver. 7, 2vCPU, 4gb RAM, 140gb storage which lives on a RAID-5 array on the host. Guest2 has: VM ver. 7, 2vCPU, 4gb RAM, 140gb storage which lives on a RAID-5 array on the host. Guest3 has: VM ver. 7, 1vCPU, 2gb RAM, 2tb storage which lives on a RAID-5 ISCSI NAS box Perhaps I am making a false assumption that if a guest has a demand for CPU (e.g. Windows Task Manager shows 100% CPU), the host would supply the guest with more CPU (mem, disk) on demand. Another Update After checking the stats, it would appear that the host is indeed not busy at all, neither is the guest. I believe I have a good idea on the issue, though; a messed-up VMWare Tools install. The guest has VMware Tools on it, but the host says it does not. VMWare Tools refuses to uninstall, refuses to be upgraded, refuses to be recognized. While I cannot say with authority, this would appear to be something worth investigation. I do not know the origin of the guest itself, nor the specifics on the original VMWare Tools install. Following various bits of googling, I did come up with a few suggestions that went nowhere. To that end, I was going to delete this question, but was prompted not to do so since so many folks answered. My suspicion right now is; the problem truly is the guest; the guest is not making a demand on the host, and as a natural result, the host is treating the guest accordingly. My Final Update I am 99% certain the guest VM had something fundamentally wrong with it re VMWare Tools. I created a clone of a different VM with a near-identical OS config, but a properly working install of VMWare tools. The guest runs just great, and takes up it's allotment of resources when it needs to; e.g. it eats up about 850mhz CPU during startup, then ticks down to idle once the guest OS is stable.

  • How to prevent Outlook from receiving multiple copies of the same email

    - by martani_net
    This question might be asked already, but it's different from this one. My boss has Outlook 2003, when he synchronize his emails while connecting through the local server (using Exchange I guess) he gets his emails normally. Once he is outside (not connection to our LAN) he gets each email duplicated 3 or 4 times. Does anyone experienced this before? and how can we fix this? Please no links to FAQ pages. For info, we are using Kaspersky anti virus and Windows 2003 server, with windows XP clients. [Update] Actually we have a bunch of 5 or 6 email accounts on Outlook, and only one of them recieve duplicated copies of the same email, all the others are cool. Further more all these email are using the sae service, Gmail for example. [Update 2] I just found out that Outlook is configured to remove emails from the server already, also, some emails exceeds 5 copies! Thank you

  • HP Compaq T20 Thin Clients & Windows Server 2008 R2: RDP Disconnects instantly.

    - by sinni800
    Hello, I have some HP Compaq T20 Thin Clients connecting to a Windows Server 2003. Now I want to upgrade to 2008 R2, so I tested a trial installation with remote desktop in administration mode. So I try to connect my T20 to the server and... It doesn't matter if I turn off encryption or not it disconnects with an generic error instantly. The T20s have Windows CE embedded with RDP 5.2 installed. Out of curiosity I tried Windows Server 2008 (no R2) and it worked! I tried the same with a Windows 7 machine set up with- no work. I can not update the T20s to Windows NT embedded for example because they only have a low amount of flash memory. It seems the "new" version of RDP coming from Windows 7 / Windows Server 2008 R2 is completely incompatible with the older 5.2 version. People are having the same problem here: http://social.technet.microsoft.com/Forums/en-US/winserverTS/thread/700488cd-a872-47e5-85a7-595f050afc10

  • Using Thunderbird and gmail, sent items appear as unread in "All Mail"

    - by Trevor
    I'm using a gmail account in Thunderbird. When I send a message, a new mail notification appears (sound and system try icon), an unread message appears in the gmail All Mail folder, and the account name turns blue. I have to click on "Sent Mail" or "All Mail" to get rid of the notification. Unsubscribing from "All Mail" is not effective (it still turns the account name blue). This seems to be popping up elsewhere (example), but nobody has posted a helpful answer. How do I keep Thunderbird from thinking that a sent message is new unread mail in the All Mail folder?
