  • Anchoring the Action URL of a Form

    - by John
    Hello, I am using a function that leads users to a file called "comments2.php": <form action="http://www...com/.../comments/comments2.php" method="post"> On comments2.php, data passed over from the form is inserted into MySQL: $query = sprintf("INSERT INTO comment VALUES (NULL, %d, %d, '%s', NULL)", $uid, $subid, $comment); mysql_query($query) or die(mysql_error()); Then, later in comments2.php, I am using a query that loops through entries meeting certain criteria. The loop contains a row with the following information: echo '<td rowspan="3" class="commentname1" id="comment-' . $row["commentid"] . '">'.stripslashes($row["comment"]).'</td>'; For the function above, I would like the URL to be anchored by the highest value of "commentid" for id="comment-' . $row["commentid"] . '" How can this be done? Thanks in advance, John

  • AJAX: Statusbar: force update of UpdatePanel while function executes

    - by John Bourke
    Hi Guys, I have a label inside an update panel which I wouldl ike to use as a status bar. Basically the user clicks a button which executes a main fucntion that performs a series of tasks. I'd like to inform the user as to the state of the function as it progresses e.g.: Stage 1: Retrieving data... Stage 2: Calculating values... Stage 3: Printing values... Stage 4: Done! I've tried updating the updatepanel directly from the function but it only updates the panel at the end of function (stage 4) and shows "Done!" (which I understand is how it should work). I've been looking into timers and threads to try and update the panel seperate to the main function but I thought I'd post here incase anyone has any better ideas? Thanks for any help in advance!

  • How to create an object reference to a xaml page from App.xaml.cs codebehind?

    - by John K.
    Hi all, I have a Silverlight 4 Business Project where I have enabled the ASP.NET Authentication/Authorization role information. I would like to pass the currently authenticated user's account information from the app.xaml.cs codebehind to a different XAML page, but I have no idea how that is done, or if it's even possible. My goal is to databind the IsEnabled property of various buttons of my target XAML page, based on whether the current user is in a particular admin related role or not. The Application_UserLoaded event handler of app.xaml.cs seems to be the safest event handler to initiate this task because it fires only after the user's account information is loaded from the server. I had previously attempted to retrieve the current user information directly from my target XAML page, but I was never getting the current user information because Application_UserLoaded hadn't finished loading the current user info yet. public partial class App : Application { private void Application_UserLoaded(LoadUserOperation operation) { // How do you create an object reference to a XAML page from your project solution // from this event handler? } } Thanks in advance for any assistance, John

  • correct approach to store in database

    - by John
    I'm developing an online website (using Django and Mysql). I have a Tests table and User table. I have 50 tests within the table and each user completes them at their own pace. How do I store the status of the tests in my DB? One idea that came to my mind is to create an additional column in User table. That column containing testid's separated by comma or any other delimiter. userid | username | testscompleted 1 john 1, 5, 34 2 tom 1, 10, 23, 25 Another idea was to create a seperate table to store userid and testid. So, I'll have only 2 columns but thousands of rows (no of tests * no of users) and they will always continue to increase. userid | testid 1 1 1 5 2 1 1 34 2 10

  • .htaccess URL is being cut at a space (I'm using Codeigniter)

    - by Ice
    I've used the following code to map https://live.example.com on to http://example.com/api Options +FollowSymLinks RewriteEngine On RewriteCond %{HTTPS} =on RewriteCond %{HTTP_HOST} ^live\.example\.com [NC] RewriteRule (.+)$ "http://example.com/api/$1" [L,P] The following url: https://live.example.com/userlinks/xml/John%20James/MvPjeUTo15/ Is suppose to map onto: http://example.com/api/userlinks/xml/John%20James/MvPjeUTo15/ Instead it maps it to: http://example.com/api/userlinks/xml/John So it seems to cut it at the space. I am using the Codeigniter framework but I am not sure if the problem lies there. Also using %20 or just a space in the url bar produces no different results. Anyone any idea and/or solution why this happens? Thank you very much, Ice

  • Allow for modular development while still running in same JVM?

    - by Marcus
    Our current app runs in a single JVM. We are now splitting up the app into separate logical services where each service runs in its own JVM. The split is being done to allow a single service to be modified and deployed without impacting the entire system. This reduces the need to QA the entire system - just need to QA the interaction with the service being changed. For inter service communication we use a combination of REST, an MQ system bus, and database views. What I don't like about this: REST means we have to marshal data to/from XML DB views couple the systems together which defeats the whole concept of separate services MQ / system bus is added complexity There is inevitably some code duplication between services You have set up n JBoss server configurations, we have to do n number of deployments, n number of set up scripts, etc, etc. Is there a better way to structure an internal application to allow modular development and deployment while allowing the app to run in a single JVM (and achieving the associated benefits)?

  • Detecting type of webserive in httpmodule

    - by Marcus
    Hi, Is there any way to detect the type of a webservice inside a httpmodule? The reason for this is that I want to do some property injection to the webservice before it's processed. I found this: http://social.msdn.microsoft.com/Forums/en/asmxandxml/thread/0e848eee-d353-4e67-b47f-89fddb600009 but that is one h..l of an ugly solution. Anyone have a nice solution?

  • Posting a form with anchor link at the end?

    - by Marcus
    I have a form for comments like the one below but after the form is posted I wish to navigate to http://www.myurl.com/mypage#commentform but I don't know how to do this. Instead of changing my form maybe there is a way to return a View with my model and add #commentform to my url? <div id="commentform"> <h2>Leave a comment</h2> <% using (Html.BeginForm("Comment","Post", FormMethod.Post)) %> <% { %> <div> <%=Html.EditorFor(post => post.Comment) %> <div class="editor-button"> <input type="submit" value="Comment" /> </div> </div> <% } %> </div>

  • Moving Webdav app from Win server 2k to Win server 2k3 now getting authentication issues.

    - by John
    I have an intranet web app that uses CSS httpFolder to map a webdav folder to an IFrame on a web page. The user then can drop files in the frame and the page processes them when the user presses the button. This works well on a Win 2k SP4 server running IIS 5. I have moved the app over to a Win 2k3 server running IIS 6. I have made sure the WebDAV extensions are allowed. I have set everything else in IIS to match the original installation on the old server. But when I try to access the WebDAV folder I am repeatedly prompted for my login credentials. I use my domain admin login but even that doesn't work. What am I missing? What differences are there between WebDAV on 2k vs 2k3? TIA John

  • Mercurial: Diff current source vs source at point in time

    - by Marcus
    I know how to view all changes in a changeset.. But let's say you update your source, you do a pull and you get 3 new changesets. How can you compare the current state of the remote repository (with the 3 changesets checked in) vs. the current source (on your local machine)? I'd like to do this using the visual diff tool which I currently have configured (Examdiff or Kdiff3).

  • How to show a client-side message with Java JSF/Tobago?

    - by Marcus
    I have a web application created with JSF and Tobago. The user types some date into a sheet and clicks a button (all within one sheet-row). Now my java class checks whether the data is correct or not. In case there are some problems, I would like to show up something like a messagebox containing the errormessage. I cannot use something like JDialog, since this would happen only server side. Every user independently of his location needs to get the message. I thought about setting the error information into a databean and having my jsp show up the message after reloading. But how can I achieve this? Is there something like a tag which can be used for this? Or can I use the "confirmation" facet for this? But how would I start it without having the user to do something? Thanks in advance!

  • Setting application affinity in gdb

    - by Marcus Ahlberg
    Is there a simple way of setting the affinity of the application I'm debugging without locking gdb to the same core? The reason why I'm asking is that the application is running with real time priority and it needs to run on a single core. At the moment I use this command line taskset -c 3 gdbserver :1234 ./app.out but the application stops responding and freezes the gdb server, making debugging impossible. I suspect that the real time priority of the application prevents gdb from executing. If I start the application and then start gdb without affinity setting, then I can attach and debug the application without gdb freezing. Is there a simple way to start gdb and the application with different affinities? Or preferably: Is there a gdb command to set affinity of the child process?

  • Understanding max JVM heap size

    - by Marcus
    I've read the max heap size on 32bit Windows is ~1.5GB which is due to the fact that the JVM requires contiguous memory. Can someone explain the concept of "contiguous memory" and why you only have max 1.5GB on Windows? Secondly, what then is the max heap size on 64 bit Windows and why is this different than what's available on 32 bit?

  • Representing element as boolean with JAXB?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually. Update: In line with the accepted answer, we created a new method returning the boolean value conditional on whether valueB == null. As we are using Hibernate, we annotated valueB with @Transient and annotated the boolean getter with Hibernate's @Column annotation.

  • Java plugin framework choice

    - by Marcus
    We're trying to determine how to implement a simple plugin framework for a service we are implementing that allows different types of calculators to be "plugged-in". After reading a number of posts about Java plugin frameworks, it seems like the most common options are: OSGI "Rolling your own" plugin framework The Java Plugin Framework (JPF) The Java Simple Plugin Framework (JSPF) OSGI seems to be more than we need. "Rolling your own" is ok but it would be nice to reuse a common library. So we're down to the JPF and JSPF. JPF seems to not be in active development right now. JSPF seems very simple and really all we need. However I haven't heard much about it. I've only seen one post on StackOverflow about it. Does anyone else have any experience with JSPF? Or any other comments on this design choice? Update: There isn't necessarily a correct answer to this.. however we're going to go with Pavol's idea as we need just a really, really simple solution. Thanks EoH for the nice guide.

  • Java Non-Blocking HTTP Server

    - by Marcus
    I have written an application using embedded Jetty that makes network calls to other services. I presume that the serving threads are idle whilst waiting for the network calls to complete. Is there any way to have a worker thread that switches between requests to perform work that can be done at the current time and then when the network calls return also handle that? A request would be returned when all work has been completed for it. I know this is a common paradigm, and I have used it for non-blocking TCP networking, but I'm unsure as to how to achieve this on a Java HTTP server whilst also waiting on external results. Any links or explanations are appreciated. Thanks
