  • return false for parent javascript function

    - by jeerose
    $("#purchaser_contact").live('submit', function(){ $.ajax({ type: "POST", url: 'ajax/contactSearch.php', data: ({ fname: $("#fname").val(), lname: $("#lname").val(), city: $("#city").val(), state: $("#state").val() }), success: function(d) { var obj = JSON.parse( d ); if(obj.result != 0){ $("#contactSearch").remove(); $("#button-wrapper").before('<div id="contactSearch">' + obj.result + '</div>'); $("#contactSearch").slideToggle('slow'); //return false from submit!! }); }); I know there are other posts on this but I couldn't figure out how to apply them properly to my situation without making it messy. How do I return false on the submit event to prevent the form from submitting if I'm within the $.ajax and success functions? Thanks.

    - by Alan
    Hi. I have a console app, and I want to capture Control-C and shutdown gracefully. I have the following code: Console.CancelKeyPress += new ConsoleCancelEventHandler((o, e) => { Logger.Log("Control+C hit. Shutting down."); resetEvent.Set(); }); And the output windows shows: 6/16/2010 3:24:34 PM: Control+C hit. Shutting down. ^C Is there a way to prevent the control-c character ^C from appearing? It's not a huge deal, but for some reason Ill be fixated on it because I'm anal like that.

  • Question about Content Delivery Networks CDN

    - by yummm
    I've built a javascript code that my clients will be installing on their website and they will be calling a file from my server. I'm wondering if it would be better to host the javascript file on a CDN, instead of on my server? The benefits would be better response time and a much higher chance that it will always be available. However, In the future, if the CDN was acquired or went out of business I would have a number of clients linking to a file that doesn't exist. Is there any way to prevent this from happening?

  • Preventing symbols from being stripped in IBM Visual Age C/C++ for AIX

    - by smountcastle
    I'm building a shared library which I dynamically load (using dlopen) into my AIX application using IBM's VisualAge C/C++ compiler. Unfortunately, it appears to be stripping out necessary symbols: rtld: 0712-002 fatal error: exiting. rtld: 0712-001 Symbol setVersion__Q2_3CIF17VersionReporterFRCQ2_3std12basic_stringXTcTQ2_3std11char_traitsXTc_TQ2_3std9allocatorXTc__ was referenced from module ./object/AIX-6.1-ppc/plugins/plugin.so(), but a runtime definition of the symbol was not found. Both the shared library and the application which loads the shared library compile/link against the static library which contains the VersionReporter mentioned in the error message. To link the shared library I'm using these options: -bM:SRE -bnoentry -bexpall To link the application, I'm using this option: -brtl Is there an option I can use to prevent this symbol from being stripped in the application? I've tried using -nogc as stated in the IBM docs, but that causes the shared library to be in an invalid format or the application to fail to link (depending on which one I use it with).

  • Filtering custom fields on wordpress admin page

    - by Kyril
    I'm currently working on a wordpress 2.9.2 plugin (my first) that creates additional custom fields that will later be read from the template. The plugin adds an additional meta box to the "Edit Post" screen which is responsible for manipulating these values. My problem is that the custom fields generated by the plugin also show up in the "Custom Fields" box. Ideally I would like for the custom fields generated by the plugin to be managed separately from any other custom fields for that same post/page. Is there a way that I can filter fields specific to my plugin to prevent them from being displayed in the "Custom Fields" box? I have yet to locate any action or filter that will let me capture and manipulate those values before they are rendered on "Edit Post".

  • Disable Eventlogging for some events using Healthmonitoring

    - by Rody van Sambeek
    I'm using basic healthmonitoring in an ASP.Net website. I'd like to prevent one event with a specific eventcode to appear in the eventlog. All other errors should be logged accordingly. I'd like to accomplish this using plain web.config settings. However I am unable to get it to work. Besides that, using IIS 5 on Windows XP does not write any events to the event log. I can't seem to find out what's wrong, on Windows 2003 it correctly logs the errors. Does anybody have an idea?

  • Search resetting selection in tableview

    - by Jay
    I've got an NSTableView bound to an NSArrayController via content and selection indexes. All great so far - content displayed, etc. Now an NSSearchField is bound to the array controller via filterPredicate and the property of the array content instances that's to be searched. Searching/filtering the table view works great; table view showing only matching entries. However, searching resets the selection on the NSTableView if the existing selection isn't in the search results. Worse, not only during the search but after ending the search there's no selection on the table view. The NSArrayController is set up to Avoid Empty Selection. Any hints on how to properly configure bindings in this scenario to really prevent an empty selection much appreciated!

  • static library vs dynamic libraries

    - by user295030
    Can someone please explain in easy terms what is static library linking vs dynamic library linking other one has a larger memory map than the other or that the static library is used to compile/link with the program that will use it versus being loaded at runtime? I also need to create a static library of a program that I made in vs2008 and give one function interface to access the library. one of the requirements reads as such " * API should be in the form of static library. company xxx will link the library into a third party application to prevent any possible exposure of the code(dll)" how can they say both static and dll at the same time. I have never works with static library before. So please any help would be nice.

  • UIPickerView and empty core data array

    - by Mark
    I have a viewcontroller showing items from a core data entity. I also have a tableview listing records from the same entity. The table is editable, and the user could remove all the records. When this happens, the view controller holding the pickerview bombs because it's looking for records in an empty array. How to prevent this? I'm assuming I need to do something different at objectAtIndex:row... # pragma mark PickerView Section - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; // returns the number of columns to display. } - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { return [profiles count]; // returns the number of rows } - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { // Display the profiles we've fetched on the picker Profiles *prof = [profiles objectAtIndex:row]; return prof.profilename; } //If the user chooses from the pickerview - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { selectedProfile = [[profiles objectAtIndex:row]valueForKey:@"profilename"]; }

  • How do I stop Safari from caching my Servlet response?

    - by Cliff
    I'm having trouble testing a web app with Safari. My app returns wave audio data. The problem happens when I change the application and hit it again from Safari. Safari caches the original response so no matter how many times I hit refresh it seems like I've not updated anything. I can almost get around this using force refresh with Firefox but because I'm having trouble generating the wave headers using the javax.sound API Firefox only plays the first second of audio returned. A few weeks ago I tried setting the HTTP header in my servlet to prevent caching but I don't think I was setting it correctly. (What is the header for browser cache control?) This is becoming a real pain and I'm looking for any ideas, comments, or alternative approaches. I'm getting ready to try again but I figured I'd ask here in the interim to see if someone can provide help.

  • IWebBrowser2: how to force links to open in new window?

    - by Rob McAfee
    The MSDN documentation on WebBrowser Customization explains how to prevent new windows from being opened and how to cancel navigation. In my case, my application is hosting an IWebBrowser2 but I don't want the user to navigate to new pages within my app. Instead, I'd like to open all links in a new IE window. The desired behavior is: user clicks a link, and a new window opens with that URL. A similar question was asked and answered here and rather than pollute that answered post, it was suggested I open a new discussion. The members on the related post suggested I should be able to do this by trapping DISPID_BEFORENAVIGATE2, setting the cancel flag, and writing code to open a new window, but I've found out that the browser control gets lots of BeforeNavigate2 events that seem to be initiated by scripts on the main page. For example, amazon.com fires BeforeNavigate2 events like crazy, and they are not a result of link invocation. Replies appreciated!

  • Silverlight Unit Testing Framework running tests in external class library

    - by Jonas Follesø
    I'm currently looking into different options for unit testing Silverlight applications. One of the frameworks available is the Silverlight Unit Test Framework from Microsoft (developed primary by Jeff Wilcox, http://www.jeff.wilcox.name/2010/05/sl3-utf-bits/). One of the scenarios I'm looking into is running the same tests on both Silverlight 3 (PC) and Windows Phone 7. The Silverlight Unit Test Framework (SLUT) runs on both PC and phone. To prevent having to copy or link files I would like to put my tests into a shared test library, that can be loaded by either a WP7 application using the SLUT, or a Silverlight 3 application using SLUT. So my question is: will SLUT load unit tests defined in a referenced class library, or only in the executing assembly?

  • Can NSTask safely be used outside the main thread?

    - by neoneye
    Yesterday I read somewhere that NSTask isn't thread safe and that bothers me a lot, because I'm running a NSTask within a NSThread and is so far not experiencing any threading issues with it. My code is organized like this A: main thread -> B: worker thread -> C: worker task C: The worker task is a commandline program. B: The worker thread can start/stop the worker task and send it commands. A: The main thread can send commands to the worker thread. If NSTask is supposed to be used only within the main thread, then I'm considering moving the NSTask start/stop code to the main thread, just to prevent possible threading issues. Can NSTask be used outside the main thread? And if not then what may be the threading issues with NSTask?

  • VSS keep resetting working folder a the root of the C: drive

    - by Alex
    I have noticed several times (that is it does not happens all the time, but occurs regulary) that VSS has forgoten my working folder settings and re-set it to be a root of the C: drive. It is very annoying to find out that some of the files you have checked out and been working on are not in the same folder where you expect them to be (and it also pollutes the drive with a C:\SubProject1, C:\SubProject2 folders instead of keeping them all inside of C:\Work). Any recomendation to prevent VSS from doing this again and again. And yes, please, don't recomment switching to SVN, CVS, TFS etc - there are the rules I can't change.

  • slashes in url variables

    - by namtax
    Hi there I have set up my coldfusion application to have dynamic urls on the page, such as www.musicExplained/index.cfm/artist/:VariableName However my variable names will sometimes contain slashes, such as www.musicExplained/index.cfm/artist/GZA/Genius This is causing a problem, because my application presumes that the slash in the variable name represents a different section of the website, the artists albums. So the URL will fail. I am wondering if there is anyway to prevent this from happening? Do I need to use a function that replaces slashes in the variable names with another character? Thanks

  • Is it possible to use HTTPS certificates for licensing?

    - by Ton van den Heuvel
    I am working on an application with multiple clients and a server running various web-services for the clients. To implement licensing I am thinking about using HTTPS as a protocol for the web-services using certificates that are issued by our company. By influencing the expiration date of a certificate for a client we can prevent them from using our software after their license term. It this possible and does it make sense to you? Additional information: I am planning on using Qt/C++ for the clients, and the Twisted framework for the web-services.

  • Documents/links on preventing HTML form fiddling?

    - by larryq
    Hi everyone, I'm using ASP.Net but my question is a little more general than that. I'm interested in reading about strategies to prevent users from fooling with their HTML form values and links in an attempt to update records that don't belong to them. For instance, if my application dealt with used cars and had links to add/remove inventory, which included as part of the URL the userid, what can I do to intercept attempts to munge the link and put someone else's ID in there? In this limited instance I can always run a check at the server to ensure that userid XYZ actually has rights to car ABC, but I was curious what other strategies are out there to keep the clever at bay. (Doing a checksum of the page, perhaps? Not sure.) Thanks for your input.

  • Timeout LinqToSql inserting millions of records

    - by Bas
    I'm inserting approximently 3 million records in a database using this solution. Eventually when the application has been inserting records for a while (my last run lasted around 4 hours), it gives a timeout with the following SqlException: "SqlExcepetion: Timeout expired. The timeoutperiod elapsed prior to completion of the operation or the server is not responding." What's the best way to handle this exception? Is there a way to prevent this from happening or should I catch the exception? Thanks in advance!

  • Removing duplicate SQL records to permit a unique key

    - by j pimmel
    I have a table ('sales') in a MYSQL DB which should have rightfully have had a unique constraint enforced to prevent duplicates. To first remove the dupes and set the constraint is proving a bit tricky. Table structure (simplified): 'id (unique, autoinc)' product_id The goal is to enforce uniqueness for product_id. The de-duping policy I want to apply is to remove all duplicate records except the most recently created, eg: the highest id Or to put another way, I would like to delete duplicate records, excluding the ids matched by the following query: select id from sales s inner join (select product_id, max(id) as maxId from sales group by product_id having count(product_id) > 1) groupedByProdId on s.product_id and s.id = groupedByProdId.maxId I've struggled with this on two fronts - writing the query to select the correct records to delete and then also the constraint in MYSQL where a subselect FROM clause of a DELETE cannot reference the same table from which data is being removed.

  • DataBind and Postback

    - by Michael La Voie
    This is a general how does DataBind work questions... I have a simple page with a GridView that is bound (in the aspx code) to an ObjectDataSource. I can look in the Select() function called by the ObjectDataSource to see that it is called on the initial load and on every post back. I have some logic that happens on post backs that will affect the GridView's data, and I want to call GridView.DataBind() later on in the post back, after I've made some changes. Is there a way to prevent the automatic rebinding that happens on each post back? Does this mean I can't use an ObjectDataSource for this control?

  • PHP Populating array with $variables

    - by Tom
    Hi, I'm trying to create a basic shopping cart, having an issue with the product page allowing users to add more items to their cart then are in stock (I have code in place to prevent this on the view cart page, just not the view product page) This is what I have so far; for ($i = 0; $i < $numItem; $i++) { extract($cartContent[$i]); $subTotal += $price * $cartQuantity; $cartLimiter[$itemNo => $cartQuantity]; Using an array so the position number becomes the item number and the cart quantity becomes the assigned value, however it doesn't seem to like it and throws out on the bottom line of code: Parse error: syntax error, unexpected T_DOUBLE_ARROW, expecting ']' Thanks

  • Singletons and other design issues

    - by Ahmed Saleh
    I have worked using different languages like C++/Java and currently AS3. Most applications were computer vision, and small 2D computer games. Most companies that I have worked for, they use Singletons in a language like AS3, to retrieve elements or classes in an easy way. Their problem is basically they needs some variables or to call other functions from other classes. In a language like AS3, there is no private constructor, and they write a hacky code to prevent new instances. In Java and C++ I also faced the situation that I need to use other classe's members or to call their functions in different classes. The question is, is there a better or another design, to let other classes interact with each others without using singletons? I feel that composition is the answer, but I need more detailed solutions or design suggestions.

  • How can a hacker put a file on my server root (apache, php, 1and1)

    - by mike-sav
    Hi there, I have a site hosted on 1and1 and a couple of weeks ago I noticed a hacker had put a .php file on the server that when viewed in a browser exposed my DB schema, DB connection strings, FTP account (for file uploads using a form), etc, etc. Naturally I panicked and I wiped the server and reuploaded my files. Fortunatley I encrypt passwords using MD5 and I don't store things like credit card details, etc, etc. Now I checked my files and with all user input I use a clean function (htmlentities, sql_real_escape_string, etc, etc) that strips the input of any XSS or SQL injection. I have also made sure that the session key gets re-engineered when a user status changes (like they log into their account) to prevent session hijacking, my folder permissions are set to 755 and file permission are 644. Has anyone got any idea how this could have happened? Or if I'm missing something

  • How can I retrieve the value of a PASTE (copy-pasta) event in a GWT TextBox?

    - by dominicbri7
    Hello fellow SO members, I want to prevent the user from copy-pasting values in my TextBox IF AND ONLY IF the values do not respect a certain condition. For instance, I created a DigitsOnlyTextBox which will be used for phone numbers. I already made it so only Character.isDigit characters can be typed into the box, and the user cannot copy-paste values into it, using : this.sinkEvents(Event.ONPASTE); and public void onBrowserEvent(Event event) { super.onBrowserEvent(event); // Permet d'empêcher le copier-coller, donc d'entrer des caractères non-numériques if (event.getTypeInt() == Event.ONPASTE) { event.stopPropagation(); event.preventDefault(); } } But I'd like to verify if the copy-pasted String is "digits only" and if so, let the event happen (therefore the text added). tl;dr : see title Thank you for your time. Sincerely.
