  • Issue on passing a checkbox set to an AppEngine script through jQuery Ajax/Json

    - by Jorge
    I have a set of checkboxes with multiple choice allowed. I parse the set this way: if ($("input[name='route_day']:checked").length > 0) { $("input[name='route_day']:checked").each(function(){ if(this.value != null) route_days_hook.push(this.value); }); dataTrap.route_days = $.JSON.encode(route_days_hook); } ...and pull the whole dataTrap to an AppEngine Python script via jQuery ajax. However, the Python script just bugs. If i change dataTrap.route_days value to a string instead of the JSON encoded object, everything works fine. My question is: how can i pass a checkbox set to the script using Ajax and still be able to iterate over it on the script?

  • non-servlet JSP

    - by h2g2java
    I realise there are EL and near EL frameworks like StringTemplate, JUEL, Velocity, etc. However, I am not asking for list of alternatives to JSTL/EL. I came across a package more than a year ago, someone who wrote a util that emulates the functionality of JSP for non-servlet env, i.e., JSP composition which does not need a "servlet container" to function. I ignored it and now I think it would be helpful to me and I need help to recall what it is. My actual motivation is similar to what StringTemplate, JUEL, Velocity would offer to help me compose SQL blocks, HTML blocks but I am thinking that JSPs are precompiled into bytecode and JSPs are more run-time efficient since run-time parsing is done no more than once. So actually, recommendation for alternatives would be acceptable as long as the templates are precompiled into bytecode. But I still prefer the JSP emulator.

  • Unwanted virtual keyboard in Blackberry app

    - by matkas
    I have developed a Blackberry app for the 4.5 os series. It works fine on all device except on the storm 1 (storm2 untested). The problem (on the storm) is that the main screen of my application (and all other screens in fact) is shown with the virtual keybord. But there is no text field displayed on the screen that would justify the VK to show up. I have bitmap fields and button fields only on that screen. The use of a single program for all devices (4.5 and up) is seriously preferred. What is causing the VK to show up and what can I do to prevent it (in JDE 4.5)?

  • Unable to persist objects in GAE JDO

    - by Basil Dsouza
    Hello Guys, I am completely fresh to both JDO and GAE, and have been struggling to get my data layer to persist any code at all! The issues I am facing may be very simple, but I just cant seem to find any a way no matter what solution I try. Firstly the problem: (Slightly simplified, but still contains all the info necessary) My data model is as such: User: (primary key) String emailID String firstName Car: (primary key) User user (primary key) String registration String model This was the initial datamodel. I implemented a CarPK object to get a composite primary key of the User and the registration. However that ran into a variety of issues. (Which i will save for another time/question) I then changed the design as such: User: (Unchanged) Car: (primary key) String fauxPK (here fauxPK = user.getEmailID() + SEP + registration) User user String registration String model This works fine for the user, and it can insert and retrieve user objects. However when i try to insert a Car Object, i get the following error: "Cannot have a java.lang.String primary key and be a child object" Found the following helpful link about it: http://stackoverflow.com/questions/2063467/persist-list-of-objects Went to the link suggested there, that explains how to create Keys, however they keep talking about "Entity Groups" and "Entity Group Parents". But I cant seem to find any articles or sites that explain what are "Entity Group"s or an "Entity Group Parents" I could try fiddling around some more to figure out if i can store an object somehow, But I am running sort on patience and also would rather understand and implement than vice versa. So i would appreciate any docs (even if its huge) that covers all these points, and preferably has some examples that go beyond the very basic data modeling. And thanks for reading such a long post :)

    In the iPod app, the navigation views have the default status bar style, and the Now Playing view is in the black style. The transition between them is animated with a crossfade.

My first attempt: [UIView beginAnimations:@"whatever" context:nil]; [UIView setAnimationDuration:0.5]; self.navigationController.navigationBar.barStyle = UIBarStyleBlack; [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlack [UIView commitAnimations]; No joy, it pops to black. Takers?

  • Problem while configuring the file Delimeter("\t") in app.config(C#3.0)

    - by Newbie
    In my app.config file I made the setting like the following <add key = "Delimeter" value ="\t"/> Now while accessing the above from the program by using the below code string delimeter = ConfigurationManager.AppSettings["FileDelimeter"].ToString(); StreamWriter streamWriter = null; streamWriter = new StreamWriter(fs); streamWriter.BaseStream.Seek(0, SeekOrigin.End); Enumerable .Range(0, outData.Length) .ToList().ForEach(i => streamWriter.Write(outData[i].ToString() + delimiter)); streamWriter.WriteLine(); streamWriter.Flush(); I am getting the output as 18804\t20100326\t5.59975381254617\t 18804\t20100326\t1.82599797249479\t But if I directly use "\t" in the delimeter variable I am getting the correct output 18804 20100326 5.59975381254617 18804 20100326 1.82599797249479 I found that while I am specifying the "\t" in the config file, and while reading it into the delimeter variable, it is becoming "\\t" which is the problem. I even tried with but with no luck. I am using C#3.0. Need help

  • What programming language is used to design google algorithm?

    - by AKN
    It is known that google has best searching & indexing algorithm. The also have good relevancy. They are also quicker in getting down the latest results. All that's fine. What programming language (c, c++, java, etc...) & database (oracle, MySQL, etc...) they have used in achieving this. Since they have to manipulate with volume of data quickly and effectively. Though I'm not looking for their indepth architecture (if in case violates their company policies) an overview of all such things could be useful. Anybody please add you valuable suggestions and insight on this?

  • Adding a red5 app in a multiuser website

    - by Zakaria
    hi everybody, I have an mvc php website where users can publish their public information: http://www.example.com/foobar/profile. Beside this project, based on some red5 samples, I have an application (done with Flex) that sends audio: rtmp://server/sendAudio (very basic but works). I want to create for each subscribed on my website an admin part where can send an audio stream: http://admin.example.com/foobar. And, when someone goes on their public profile, they can listen to the streamed audio: http://www.example.com/foobar/profile). How can I use my red5/flash app dynamically with my php website so that my users can broadcast their proper canal? Do you have some experience to share ? Thank you, Regards.

  • Smart Client App: How to give Different Settings for Different Users

    - by Daniel
    Hi! I have a smart client application being deployed with a CickOnce webpage. here's the current scenario. User runs the application, and the application shows a login form. User enters ID/Password in the login form, and the application sends that information to the server. The server authenticates the user and sends configuration and data to the application. Different users have different configuration and data for their application. I was concerned that anyone can download the application from the webpage if they know the URL. So I'm trying to change the authentication scheme, so that users can login at the webpage to download the application. I want to send the authentication info from the webpage(Program running at the server) to the smart client app, so that application can download the configuration information from the server, without prompting users to make a login again. How can the webpage send the ID/Passoword to the application securely?

  • Database storage for high sample rate data in web app

    - by Jim
    I've got multiple sensors feeding data to my web app. Each channel is 5 samples per second and the data gets uploaded bundled together in 1 minute json messages (containing 300 samples). The data will be graphed using flot at multiple zoom levels from 1 day to 1 minute. I'm using Amazon SimpleDB and I'm currently storing the data in the 1 minute chunks that I receive it in. This works well for high zoom levels, but for full days there will be simply be too many rows to retrieve. The idea I've currently got is that every hour I can crawl through the data and collect together 300 samples for the last hour and store them in an hour Domain (table if you like). Does this sound like a reasonable solution? How have others implemented the same sort of systems?

  • Hide a single content block from search engines?

    - by jonas
    A header is automatically added on top of each content URL, but its not relevant for search and messing up the all the results beeing the first line of every page (in the code its the last line but visually its the first, which google is able to notice) Solution1: You could put the header (content to exculde from google searches) in an iframe with a static url domain.com/header.html and a <meta name="robots" content="noindex" /> ? - are there takeoffs of this solution? Solution2: You could deliver it conditionally by apache mod rewrite, php or javascript -takeoff(?): google does not like it? will google ever try pages with a standard users's useragent and compare? -takeoff: The hidden content will be missing in the google cache version as well... example: add-header.php: <?php $path = $_GET['path']; echo file_get_contents($_SERVER["DOCUMENT_ROOT"].$path); ?> apache virtual host config: RewriteCond %{HTTP_USER_AGENT} !.*spider.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yahoo.* [NC] RewriteCond %{HTTP_USER_AGENT} !Bing.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yandex.* [NC] RewriteCond %{HTTP_USER_AGENT} !Baidu.* [NC] RewriteCond %{HTTP_USER_AGENT} !.*bot.* [NC] RewriteCond %{SCRIPT_FILENAME} \.htm$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.html$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.php$ [NC] RewriteRule ^(.*)$ /var/www/add-header.php?path=%1 [L]

  • looking to streamline my RSS feed mashup

    - by Mark Cejas
    Hello crafty developers, I have aggregated RSS feeds from various sources with RSSowl, fetching directly from the social mention API. The RSS feeds are categorized into the following major categories: blogs, news, twitter, Q&A and social networking sites. Each major category is nested with a common group of RSS feeds that represent a particular client/brand ontology. Merging these feeds into the RSSowl reader application, allows me to conduct and save refined search queries (from the aggregated data) into a single file - that I can then tag and further segment for analysis. This scheme is utilized for my own research needs and has helped me considerably. However, I find this RSS mashup scheme kinda clumsy, it requires quite a bit of time to initially organize all of the feeds and I would like to be able to do further natural language processing to the data as well as eventually be able to rank the collected list of URL's into some order of media prominence - right I don't want to pay the ridiculous radian6 web analytics fees, when my intuition is telling me that with a bit of 'elbow grease' I can maybe leverage some available resources online to develop a functional low scale web mining application and get some good intelligence from it. I am now starting to learn a little about computer science - my background is in physical science/statistics so is my thinking in the right track? So, I guess I am imagining an application that allows me to query in a refined manner. A manner that allows me to search for keyword combinations, applying AND/OR operators, selectively focus my queries into particular sources - like a collection of blogs or twitter, or social networking communities, then save the results of my queries into a structured format that can then be manipulated and explored. Am I dreaming? I just had to get all of this out. any bit of advice and insight would be hugely appreciated. my best, Mark

  • Show UIView for app presentation only once in iOS

    - by André Muniz
    I need to show an UIScrollView with some pages for present the app to user when launched for the first time. My slides are working correctly, lefting the logic to present it. Is a good practice to set the UIScrollViewController as root controller and set a NSUserDefault variable to control the presentation and redirect to main controller or set the main ViewController as root normally and call the presentation view if needed is a better approach? If there is a better way to do this can someone help? Thanks.

  • How to prevent autoplay and run my own app when inserting an USB-Flash drive

    - by Thomas
    when inserting an USB-Flash drive, Windows normally opens the Autoplay dialog that offers to browse the drive or if there are multimedia files it offers to choose an app to open them. We developed a media player that is connected to the USB-Drive and registers itself as Mass Storage Device. What I need is, that when inserting the Player that this Dialog is not shown, but instead my own application is launched. Ideally the application would be on the Flash Drive itself, but as I understood is that Autorun is disabled for USB-Drives. It would be enough if a preinstalled application is launched. I already tried to catch the WM_DRIVE_CHANGE message, but this only works if my application is the top most window, otherwise the Autoplay Dialog is displayed. Best Tom

  • Storing search result for paging and sorting

    - by Mattias
    I've been implementing MS Search Server 2010 and so far its really good. Im doing the search queries via their web service, but due to the inconsistent results, im thinking about caching the result instead. The site is a small intranet (500 employees), so it shouldnt be any problems, but im curious what approach you would take if it was a bigger site. I've googled abit, but havent really come over anything specific. So, a few questions: What other approaches are there? And why are they better? How much does it cost to store a dataview of 400-500 rows? What sizes are feasible? Other points you should take into consideration. Any input is welcome :)

  • Difference between internet and Desktop jave EE app server

    - by immer
    Hello. I need some clarification. I know that in order to run a java EE project, one needs a java EE compliant application server, such as tomcat, jboss, glashfish, etc. But, i download these to my desktop, but how about when i run it online? Are Jboss, tomcat, glashfish, etc. application servers just for your desktop, or are these the app server internet service providers have as well. I am trying to use godaddy as my internet service provider; i called them, but the customer service guy didnt know what application server they had, or did i ask the wrong question? Or how can i know waht application server they have? Thank you, any help is greatly appreciated.

  • GWT as offline app, to be deployed onto an iPad

    - by Maroloccio
    I often use GWT for web UIs. I have heard of it being used a fair bit in conjunction with Gears for offline solutions (probably nowadays HTML5 "offline storage" is all the rage) and I'd like to experiment with building a GUI in GWT and use it on my iPad. Tips/tutorials on how to deploy it onto the device to act as much as possible like a resident "App"? This is just a curiosity/experiment to fill a week-end... (I can "free" the iPad for the experiment if need be yet I am sure a lot can be done without doing so...)
