  • Jquery Google Maps Problem

    - by Matias
    Here is the problem: Lets say a Jquery toggle button which loads a Google Map upon request and hides its later when toggled: $('#showmeMap').toggle(function() { var map = new GMap2($("#map").get(0)); var mapCenter = new GLatLng(-2, 20); map.setCenter(mapCenter, 12); $('#map').show(); } }, function() { $('#map').hide(); }); Then I add some random markers and later another function which removes markers from the map: $('#destroyMarkersButton').click(function() { for (var i=0; i<gmarkers.length; i++) { map.removeOverlay(gmarkers[i]); } }); When clicking on the button I´ve got the error Map is undefined. My thought was defining Google Map object globally: map = new GMap2($("#map").get(0)); Which works perfectly in Firefox, however, map fails to load on internet explorer!! Any suggestions ?

  • Java how to load modules

    - by gerardorn
    heres my problem: im building a server that loads modules. each module is a .jar file. inside the jar theres all the classes that the module need. the server needs to read the jar, find the main class (it doesnt have the main method on it is just the class that makes the module work but not as a different program), build an object of that class and store it in a vector of modules so that it can acces to a specific module depending on the job to be done. how can i do that? as far as the server, it is listening and reciving request, but thes no modules to delegate the job to, since my vector of modules is empty

  • document.getElementById("tweetform").submit is not a function?

    - by Abs
    Hello all, I am using Firefox and I've been reading some forums claiming this doesn't work in firefox but it has been working for me for the last few days but has stopped working and I can not figure out why. I make a AXAX POST Request using an IFrame. When I get the response I use this: function startLoad(){ $.get("update.php", function(data){ if(data==''){ startLoad(); } else{ document.getElementById("tweetform").submit(); } }); } However, from firebug, I get this: document.getElementById("tweetform").submit is not a function [Break on this error] document.getElementById("tweetform").submit(); I know submit exists, but what is going on? Thanks all

  • How to convert a void pointer to array of classes

    - by user99545
    I am trying to convert a void pointer to an array of classes in a callback function that only supports a void pointer as a means of passing paramaters to the callback. class person { std::string name, age; }; void callback (void *val) { for (int i = 0; i < 9; i++) { std::cout << (person [])val[i].name; } } int main() { person p[10]; callback((void*)p); } My goal is to be able to pass an array of the class person to the callback which then prints out the data such as their name and age. However, the compile does not like what I am doing and complains that error: request for member 'name' in 'val', which is of non-class type 'void*' How can I go about doing this?

  • Caching images with different query strings (S3 signed urls)

    - by Brendan Long
    I'm trying to figure out if I can get browsers to cache images with signed urls. What I want is to generate a new signed url for every request (same image, but with an updated signature), but have the browser not re-download it every time. So, assuming the cache-related headers are set correctly, and all of the URL is the same except for the query string, is there any way to make the browser cache it? The urls would look something like: http://example.s3.amazonaws.com/magic.jpg?WSAccessKeyId=stuff&Signature=stuff&Expires=1276297463 http://example.s3.amazonaws.com/magic.jpg?WSAccessKeyId=stuff&Signature=stuff&Expires=1276297500 We plan to set the e-tags to be an md5sum, so will it at least figure out it's the same image at that point? My other option is to keep track of when last gave out a url, then start giving out new ones slightly before the old ones expire, but I'd prefer not to deal with session info.

  • Date or String declaration in a javabean

    - by Jeff
    Should I declare an attribute in a javabean that holds a date value a user types in on an HTML form as a String or Date? I feel I should declare as a Date, however, since I do server validation on all form data, if the date doesn't validate, when I pass the form bean back to the jsp view for correcting, I lose the date value that the user tried to type in. If I declare as a String, if the date doesn't validate, I'm able to set the string value in the bean and pass the bean back to the view and the user can see what they incorrectly typed. But with a String declaration for Date inputs I forsee problems down the road with my DAO. I want to be able to use a DAO utility which generates a prepare statement using setObject. In my html form I request dates to be mm/dd/yyyy and in DAO i'm using Oracle Date. I can not use hibernate or such, since this is a corporate intranet. What is the best practice "pattern" I should be following??

  • Designing DAOs for data sources other than a database

    - by James P.
    Hi, Until now I've been used to using DAOs to retrieve information from databases. Other sources of data are possible though and I'm wondering if and how the pattern could be applied in general. For example, I'm now working on an application that fetches XML on the web. The XML file could be considered as a data source and the actual fetching is similar in principle to a database request. I'm not quite sure how the DAO could be structured though. Any views on the subject are welcome.

  • How can I delete a file in Sinatra after it has been sent via send_file?

    - by John Reilly
    I have a simple sinatra application that needs to generate a file (via an external process), send that file to the browser, and finally, delete the file from the filesystem. Something along these lines: class MyApp < Sinatra::Base get '/generate-file' do # calls out to an external process, # and returns the path to the generated file file_path = generate_the_file() # send the file to the browser send_file(file_path) # remove the generated file, so we don't # completely fill up the filesystem. File.delete(file_path) # File.delete is never called. end end It seems, however, that the send_file call completes the request, and any code after it does not get run. Is there some way to ensure that the generated file is cleaned up after it has been successfully sent to the browser? Or will I need to resort to a cron job running a cleanup script on some interval?

  • require.js - How can I set a version on required modules as part of the URL?

    - by Ovesh
    I am using require.js to require JS modules in my application. I need a way to bust client cache on new JS modules, by way of a different requested URL. i.e., if the file hello/there.js has already been cached on the client, I can change the file name to force the browser to get the new file. In other words, for the module hello/there, I'd like require.js to request the url hello/there___v1234___.js (the file name can look different, it's just an example), according to a version string which is accessible on the client. What is the best way to achieve that?

  • Is it possible to authenticate user manually with oauth2

    - by iixi
    I want to authenticate a user with oauth2 to access google drive. I can get the access token required when using AccountManager to retrieve an account and then get the token with: mgr.blockingGetAuthToken(account, ApiConst.DRIVE_AUTH_SCOPE, true); But I want the user to be able to authenticate by providing username and password instead of using the account added to the phone. Is this possible? EDIT So I have tried to implement the authorization in a WebView. I followed this example. I have extracted the code request parameter but the code used to retrieve the access token seems to be deprecated and not compatible with the packages used by Google Drive SDK. This is the code used to retrieve the access token in the example: AccessTokenResponse accessTokenResponse = new GoogleAuthorizationCodeGrant(new NetHttpTransport(), new JacksonFactory(), OAuth2ClientCredentials.CLIENT_ID, OAuth2ClientCredentials.CLIENT_SECRET, code, OAuth2ClientCredentials.REDIRECT_URI).execute(); Can this be done in some other way or should I just give up?

  • Can someone explain Kohana 3's routing system?

    - by alex
    In bootstrap.php, where you set routes, I'm having a hard time getting them to work. I read some documentation a while ago that I can't seem to find again that explains them. Here is one of my examples Route::set('products', 'products/(type)', array('type' => '.+')) ->defaults(array( 'controller' => 'articles', 'action' => 'view_product', 'page' => 'shock-absorbers', )); I thought that would mean a request like products/something would load up the articles controller, and the action_view_product method. But I can't get it to work. Can someone please explain to me exactly how they work, and what all the method parameters are?

    - by sameer
    Have come across a situation where in, if a stored procedure is executed in Query Analyser its execution time is less than a second.

Therefore inorder to troubleshoot this issue we went to SQL Profiler we find the request come to SQL Server less then a second but execution completed after 60 seconds. Can anybody suggest why we have such a deviation. Query is a simple as give below SELECT distinct p1.productID, p1.description FROM Details V INNER JOIN Product P ON V.ProductID=P.ProductID INNER JOIN product p1 on p1.productID=p.parentID WHERE V.MarketID='1159' AND V.FinancialYear='1213' AND V.LEPeriodID= '75' AND p1.parentID=100024 AND p1.statusID = 1 ORDER BY description

  • Session State ArrayList in Shopping Cart ASP.NET

    - by user330342
    Hi guys, I'm creating a shopping cart application and I'm having some issues with implementing a session state for my arraylist. in my page load i declared if (Session["Cart"] == null) { Session["Cart"] = new ArrayList(); } else { ArrayList cart = (ArrayList)Session["Cart"]; } to create the session if it doesn't exist yet. then i have an event handler for a button to add items to the arraylist protected void onClick_AddBooking(object sender, EventArgs e) { int ClassID = Convert.ToInt32(Request.QueryString.Get("Class_Id")); ArrayList cart1 = new ArrayList(); cart1 = Session["Cart"]; cart1.Add(ClassID); i'm guessing i just don't know how to handle session states yet, thus the confusion. I'm essentially storing the class_ID then when the student confirms i'll store that to the DB and associate that ID with the Class Details. Thanks in advance guys!

  • Common optimization rules

    - by mafutrct
    This is a dangerous question, so let me try to phrase it correctly. Premature optimization is the root of all evil, but if you know you need it, there is a basic set of rules that should be considered. This set is what I'm wondering about. For instance, imagine you got a list of a few thousand items. How do you look up an item with a specific, unique ID? Of course, you simply use a Dictionary to map the ID to the item. And if you know that there is a setting stored in a database that is required all the time, you simply cache it instead of issuing a database request hundred times a second. I guess there are a few even more basic ideas. I am specifically not looking for "don't do it, for experts: don't do it yet" or "use a profiler" answers, but for really simple, general hints. If you feel this is an argumentative question, you probably misunderstood my intention.

  • Rails: Generic form actions, cancel link losing `:back` on validation failure

    - by Patrick Connor
    I am trying to create a generic set of Submit, Cancel, and Destroy actions for forms. At this point, it appears that everything is working, except that I lose :back functionality then a form reloads due to validation errors. Is there a way to catch the fact that validation has failed, and in that case, keep the request.env['HTTP_REFERER'] or :back value the same without having to edit every controller? = simple_form_for @announcement do |f| = f.error_notification = f.input :message = f.input :starts_at = f.input :ends_at #submit = f.button :submit = "or " = link_to("cancel", url_for(:back)) .right - if !f.object.new_record? - resource = (f.object.class.name).downcase = link_to "destroy", url_for(:action => 'destroy'), :confirm => "Are you sure that you want to delete this #{resource}?", :method => :delete .clear .non_input #post_back_msg #indicator.inline = image_tag "indicator.gif" .inline = "Please wait..." .non_input

  • Can I expand macro JUST ONE TIME in specific target?

    A = "demo" %.o:%.cpp $(CC) -c $^ $(A) -o $@ default:$(all_objs) game:A = $(shell read -p 'Enter game version: ' gv && echo $$gv) game:$(all_objs) Just a snippet makefile above. If I make game, main problem is each compilation of sources will expand $(A) and it will request user to input game version over and over. $(A) has default content "demo" only if user doesn't make game target. So, is there any way to set $(A) to be expanded && ?

  • How to I preload images where it actually forces the images to load before continuing (html/javascri

    - by Mr. Flibble
    I want to preload images but ensure they are loaded before continuing. How can I do this? The following does not work as it sends off the load request only, but doesn't wait till the image is loaded. So it is possible that the image isn't loaded when requested soon after. jQuery.preloadImages = function () { for (var i = 0; i < arguments.length; i++) { jQuery("<img>").attr("src", arguments[i]); } } $.preloadImages("img1.jpg","img2.jpg");

  • How to manually close connection in BaseHTTPServer?

    - by user1657188
    I have a script that sends a request to an HTTP server. HTTP server script (snippet): ... class MyHandler(BaseHTTPServer.BaseHTTPRequestHandler): def do_GET(sa): pdict = cgi.parse_header(sa.headers.getheader('referer')) q = pdict[0] q = urllib.unquote(q) if q == "enternetixplorer" # basically just ignore this, doesn't have to do with the question sa.wfile.write("blah blah blah") # now restart server httpd.server_close() python = sys.executable os.execl(python, python, * sys.argv) ... The "blah blah blah" is sent back, but the connection does not seem to close, and my script is waiting forever until I abort the server. (My thought is BaseHTTPServer automatically closes connection when the last part in "do_GET()" is computed, but I prevent this by restarting the script.) If I'm right, how do I close the connection? If not, what else might be the problem? Edit: The server script HAS to restart the entire program.

  • How to setup custom CSS based on account settings in a Django site?

    - by sdolan
    So I'm writing a Django based website that allows users select a color scheme through an administration interface. I already have middleware/context processors that links the current request (based on domain) to the account. My question is how to dynamically serve the CSS with the account's custom color scheme. I see two options: Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors. Use a custom URL (e.g. "/static/dynamic/css//styles.css") that gets routed to a view that grabs all the necessary values and creates the css file. I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".
