  • Google Spreadsheet API problem: memory exceeded

    - by Robbert
    Hi guys, Don't know if anyone has experience with the Google Spreadsheets API or the Zend_GData classes but it's worth a go: When I try to insert a value in a 750 row spreadsheet, it takes ages and then throws an error that my memory limit (which is 128 MB!) was exceeded. I also got this when querying all records of this spreadsheet but this I can imaging because it's quite a lot of data. But why does this happen when inserting a row? That's not too complex, is it? Here's the code I used: public function insertIntoSpreadsheet($username, $password, $spreadSheetId, $data = array()) { $service = Zend_Gdata_Spreadsheets::AUTH_SERVICE_NAME; $client = Zend_Gdata_ClientLogin::getHttpClient($username, $password, $service); $client->setConfig(array( 'timeout' => 240 )); $service = new Zend_Gdata_Spreadsheets($client); if (count($data) == 0) { die("No valid data"); } try { $newEntry = $service->insertRow($data, $spreadSheetId); return true; } catch (Exception $e) { return false; } }

  • Disable buttons on post back using jquery in .net app

    - by Chris Lively
    I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway. What I've tried is: $(document).ready(function () { $("#aspnetForm").submit(function () { $('input[type=submit]', $(this)).attr("disabled", "disabled"); }) }); The above will disable the button, and the page submits, but the asp.net button on click handler is never called. Simply removing the above and the buttons work as normal. Is there a better way?

  • Use Google AppEngine datastore outside of AppEngine project

    - by Holtwick
    For my little framework Pyxer I would like to to be able to use the Google AppEngine datastores also outside of AppEngine projects, because I'm now used to this ORM pattern and for little quick hacks this is nice. I can not use Google AppEngine for all of my projects because of its's limitations in file size and number of files. A great alternative would also be, if there was a project that provides an ORM with the same naming as the AppEngine datastore. I also like the GQL approach very much, since this is a nice combination of ORM and SQL patterns. Any ideas where or how I might find such a solution? Thanks.

  • Corrupt iPhone App Name

    - by vickirk
    I've done an adhoc build to test an application, but when I drag it into iTunes to add to my devices it is getting a corrupt name. It comes up with the name "Myapp Name <!DOCTYPE plist PUBLIC "-//APPLE//DTD PLIST 1.0//EN" http://www.apple.com/DTDs/PropertyList-1.0.dtd"" which continues with the whole plist I've tried the obvious, clean/rebuild/reboot. This worked fine last time I worked on the app and I've done nothing to project settings other than incement the version number and a couple of minor code changes. I've since update XCode to 3.2.1 and iTunes to 9.0.3. Anyone seen this before?

  • Suggestions for a mashup application

    - by Raffo
    I have to write a mashup application for an university course and I have to use some APIs, but I need to choose by myself what to use and what the final application should do. Unfortunately I never made an application like this, so I'm not sure what to do... I don't want to code a stupid app which uses google maps' APIs since the web seems to be full of stuff like this. Have you got any suggestion for me? Is there any mashup web app you want that's still not there?? I can use JAVA, GWT (and google app engine of course) or python, but I also accept suggestions for other languages. Thank you in advance!

  • Shutting down a WPF application from App.xaml.cs

    - by Johannes Rössel
    I am currently writing a WPF application which does command-line argument handling in App.xaml.cs (which is necessary because the Startup event seems to be the recommended way of getting at those arguments). Based on the arguments I want to exit the program at that point already which, as far as I know, should be done in WPF with Application.Current.Shutdown() or in this case (as I am in the current application object) probably also just this.Shutdown(). The only problem is that this doesn't seem to work right. I've stepped through with the debugger and code after the Shutdown() line still gets executed which leads to errors afterwards in the method, since I expected the application not to live that long. Also the main window (declared in the StartupUri attribute in XAML) still gets loaded. I've checked the documentation of that method and found nothing in the remarks that tell me that I shouldn't use it during Application.Startup or Application at all. So, what is the right way to exit the program at that point, i. e. the Startup event handler in an Application object?

  • GAE and Socket Data

    - by Vinod
    I have a field device which keeps on sending data over to any designated port using sockets. I am planning to use GAE for server-side infrastructure. I read GAE does not support sockets. But i can configure the device to send the data over port 80. so we wrote a genericservlet to capture this data on GAE. But it is not obtaining any values from the client. any suggestions to fix this issue?

  • building a web application in eclipse

    - by Noona
    As a concluding assignment for the technologies taught in a data management course, we have to write a web application using the technologies taught throughout the course, this mostly includes xhtml, css, JSP, servelets, JDBC, AJAX, webservices. the project will eventually be deployed using tomcat. we are given the option of choosing the technologies that we see fit. since this is my first time developing a web application I am having some uncertainties about where to start, so for example now I am writing the object classes that will be used in the database and implementing the operations that will be performed on the database, but I am not sure about how to make these operations available to a client through the website, I mean I think I have to write a servlet through which I can extract the request parameters and set the response accordingly, but I would still like a more specific overview of what I am going to do, so if someone can link me to a tutorial with an example that makes use of these technologies while illustrating the stages of the design so that I can see how all these things are linked together in a web project. thanks

  • Implementing tagging in JDO

    - by Julie Paltrow
    I am implementing a tagging system for a website that uses JDO . I would like to use this method. However I am new to relationships in JDO. To keep it simple, what I have looks like this: @PersistentCapable class Post { @Persistent String title; @Persistent String body; } @PersistentCapable class Tag { @Persistent String name; } What kind of JDO relationships do I need and how to implement them? I want to be able to list all Tags that belong to a Post, and also be able to list all Posts that have a given Tag. So in the end I would like to have something like this: Table: Post Columns: PostID, Title, Body Table: Tag Columns: TagID, name Table: PostTag Columns: PostID, TagID

  • How to determine what in my script is blocking my HTML rendering?

    - by Vicki
    I have a web application that uses quite a bit of JavaScript. When the page loads, it's very clear visually that something is blocking the rendering of a particular portion of the web site. This portion is generated by a Tabber Tabify JavaScript library. How can I determine what's blocking the HTML rendering specifically so that I can modify my code to prevent this blocking? Can I use Firebug, or some other tool, to walk through my HTML/JavaScript to determine where the HTML rendering is being blocked and if so, how? UPDATE: YSlow gives my web-application a score of "A" and Page Speed give a score of 94/100. UPDATE 2: The live site is linked below. http://www.uptownelite.com/index.uncompressed.html?city=Dallas,TX What I'm specifically referring too is the actual Tabs themselves being rendering (and NOT the panel content inside the tab panes). It seems strange to me that the Tab headings themselves are taking so long to generate on the first (empty cache) page load.

  • Good portfolio projects

    - by David
    Hi, I am a recent graduate and am looking to start a career in web development. Its kind of a catch 22 at the moment as I have a fair bit of programming experience from university but not really in web development and to get a job in web development a portfolio is typically required. So, I am looking to start a building a few application in order to have something to show potential employers. Im more into the backend stuff although am just as comfortable with front end development. Does anyone have any thoughts on some potential projects that would be both relatively quick (as i need to get a job soon!) to build but show off enough programming knowlege / skills to be impressive to employers. At the moment i am also learning to use the zend framework and I would hope to find work using such a framework (mvc). My initial thoughts would be things like a webmail app or maybe a custom CMS. Any ideas would be greatley appreciated.

  • Automatic logout in python web app

    - by Ali
    I have a web application in python wherein the user submits their email and password. These values are compared to values stored in a mysql database. If successful, the script generates a session id, stores it next to the email in the database and sets a cookie with the session id, with allows the user to interact with other parts of the sight. When the user clicks logout, the script erases the session id from the database and deletes the cookie. The cookie expires after 5 hours. My concern is that if the user doesnt log out, and the cookie expires, the script will force him to login, but if he has copied the session id from before, it can still be validated. How do i automatically delete the session id from the mysql database after 5 hours?

  • Emailing HTML from within an iPhone app is stopping at special characters

    - by user141146
    Hi, I have an iPhone app that will let users email some pre-determined text as HTML. I'm having a problem in that if the text contains special characters within the text (e.g., ampersand &, , <), the NSString variable that I use for sending the body of the email gets truncated at the special character. I'm not sure how to fix this (I tried using the method stringByAddingPercentEscapesUsingEncoding…but this hasn't fixed the problems). Thoughts on what I'm doing wrong / how to fix it? Here is sample code showing what I'm trying to do Thanks!!! - (void)send_an_email:(id)sender { NSString *subject_string = [NSString stringWithFormat:@"Summary of %@", commercial_name]; NSString *body_string = [NSString stringWithFormat:@"%@<br /><br />", [self.dl email_message]]; // email_message returns the body of text that should be shipped as html. If email_message contains special characters, the text truncates at the special character NSString *full_string = [NSString stringWithFormat:@"mailto:?to=&subject=%@&body=%@", [subject_string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], [body_string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; [[UIApplication sharedApplication] openURL:[[NSURL alloc] initWithString:full_string]]; }

  • PHP: How should I move my code from dev to production?

    - by Teddy
    I have created a PHP web-application. I have 3 environments: DEV, TEST, PROD. What's a good tool / business practice for me to move my PHP web-application code from DEV to TEST to the PROD environment? Realizing that my TEST environment still only connects to my TEST database; whereas, I need to PROD environment to connect to my PROD database. So the code is mostly the same, except that I need to change my TEST code once moved into PROD to connect to the PROD database and not TEST database. I've heard of people taking down Apache in such away that it doesn't allow new connections and once all the existing connections are idle it simply brings down the web server. Then people manually copy the code and then manually update the config files of the PHP application to also point to the PROD instance. That seems terribly dangerous. Does a best practice exists?

  • A little bit more complicated multiview App for Iphone

    - by Thomas Losert
    Hi, i'm new to iphone development. I spend several days by looking for how write muliview app for an Iphone OS. I found how to switch the diferent views without navigation hierarchy (in this article). It's great, but i want more complicated function. For example, i have three diferent views (view 1 - 3) and i can switch between them with technique from link 1. It works fine. My question is: How can i put UITabBarController on view 2, that shows own subviews (tabView 1 - 3) and how put UINavigationController on view 3, that shows own subviews (navView 1 - 2)? The reslut should look like that, one main view (view 1) with two buttons (for example), which switch me to "window" with UiTabBarController or UINavigationController. I found only tutorials, where UITabBarController was a first controller class, that shows directly from AppDelegate (something like default Xcode predefined scenarios). Thanks for your helpfull answer, or i will be crazy soon:).

  • Is Alpha Five Version 10 really all that its reported to be?

    - by Gary B2312321321
    I came across this RDMS via the advert on stackoverflow. Seems to be in the vein of MS Access / Filemaker / Apex database devlopment tools but focused on web based applications. It quotes rave reviews from EWeek and a favourable mention from Dr Dobbs regarding its ability to create AJAX web applications without coding. The Eweek review, apparently written by an ASP.NET programmer, goes on to proclaim the ease at which apps can be extended using the inbuilt XBasic language and how custom javascript can easily be added without wading through code. Has anyone here built a web app with Alpha 5? Does anyone have comments on the development process, the speed of it or limitations they encountered along the way? To me it seems Oracle APEX comes closest to the feature set, has anyone programmed in both and have any comments?

  • Is there some performance issue between leaving empty ListProperties or using dynamic (expando) prop

    - by indiehacker
    Is there a datastore performance difference between adding dynamic properties of the expando class when they are needed for an entity or the simpler (for me) framework of just setting up all possible properties I might need from the start even though most instances will just be left empty. In my specific case I would be having 5-8 empty ReferenceList properties as 'overhead' that will be empty when I skip using expando class.

  • Loading textures in an Android OpenGL ES App.

    - by Omega
    I was wondering if anyone could advise on a good pattern for loading textures in an Android Java & OpenGL ES app. My first concern is determining how many texture names to allocate and how I can efficiently go about doing this prior to rendering my vertices. My second concern is in loading the textures, I have to infer the texture to be loaded based on my game data. This means I'll be playing around with strings, which I understand is something I really shouldn't be doing in my GL thread. Overall I understand what's happening when loading textures, I just want to get the best lifecycle out of it. Are there any other things I should be considering?
