  • Regex to match CSV file nested quotes

    - by user361970
    Hi, I know this has been discussed a million times. I tried searching through the forums and have seen some close regex expressions and tried to modify them but to no avail. Say there is a line in a csv file like this: "123", 456, "701 "B" Street", 910 Is there an easy regex to detect "B" (since its a non-escaped set of quotes within the normal CSV quotes) and replace it with something like \"B\" ? The final string would end up looking like this: "123", 456, "701 \"B\" Street", 910 Help would be greatly appreciated!

  • iOS Facebook Access Token To Get User Wall Feed (status)

    - by Felix
    [DISCLAIMER : None of the access token or ID below here are real] I've done research for three solid days and no result on how to get user wall feed(post). I have used https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials and get the access token which is something like this access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN and then https://graph.facebook.com/100005939123542/feed?access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN It gives me general information such as user's likes, name, id, current city... but NOT user's wall posts. I've learned that there are three types of access token, which is App Token, User Token, and Page Token. In order to get user/feed by using graphAPI, I need to request to get User Token, but there's NO information in the lousy Facebook Doc! (Which frustrated me the most!) In order to generate the user access token, we need to set some permission, generate the access token, and GET the user's wall feed, which is in JSON format. My question is : How do I get the User Access Token in order to get user wall post in iOS Xcode?

  • JSF, How to set a property in a different page/backing bean and then navigate to that page?

    - by kgrad
    I am using JSF 2.0 and attempting to pass values between different pages in my App. The setup is as follows: I have a page called userSelect that has a backing bean userSelectBacking. On this page I display a list of users that can be selected and submit using an h:commandbutton, when the page is submit the navigation goes to a userEdit page. I have a page called userEdit, that has a backing bean userEditBacking which displays the information for a user and allows that user to be edited. I would like to pass the user selected from the userSelect page into the userEdit page. I am currently using f:setPropertyActionListener to set the user in my userEdit backing from the userSelect page, however when I navigate to the userEdit page, it loses the information I set. is there a way that I can pass the values between the two pages/backing beans? thanks

  • Prevent an Activity from being killed by the OS while starting a child activity

    - by Martin Marinov
    I have a main activity which calls a child one via Intent I = new Intent(this, Child.class); startActivityForResult(I, 0); But as soon as Child becomes visible the main activity gets its onStop and immediately after that onDestroy method triggered. And as soon as I call finish() within the Child activity or press the back button, the Child activity closes and the home screen shows (instead of the main activity). How can I prevent the main activity from being destroyed? :\

  • JToolbar is hidden by JMenu

    - by pierre
    I'm using Netbeans to add a JToolbar to my window which also has a JMenuBar. Here is the design-time look: .. but during run-time I get this: With the toolbar seemingly partially hidden under the menu names. This is on the Mac, btw. Is there something stupid I've forgotten to do or some layout trick I should be using? EDIT: I'll add that the area below the toolbar is a SplitContainer.

  • Server Emulator Design Pattern

    - by adisembiring
    I wanna build server socket emulator, but I want implement some design pattern there. I will described my case study that I have simplified like these: My Server Socket will always listen client socket. While some request message come from the client socket, the server emulator will response the client through the socket. the response is response code. '00' will describe request message processed successfully, and another response code expect '00' will describe there are some error while processing the message request. IN the server there are some UI, this UI contain check response parameter such as. response code timeout interval While the server want to response the client message, the response code taken from input parameter response form UI check the timeout interval, it will create sleep thread and the interval taken from timeout interval input from UI. I have implement the function, but I create it in one class. I feel it so sucks. Can you suggest me what class / interface that I must create to refactor my code.

  • JDO in Google App Engine: order of keys in unowned one-to-many relationship

    - by Kel
    I'm implementing web application with JDO in Google App Engine. According to documentation, in owned one-to-many relationships, order of elements in "owner" object collection is determined either by automatically created index field, or by information given in explicit ordering clause. For example: @PersistenceCapable public class Person { // ... @Order(extensions = @Extension(vendorName="datanucleus", key="list-ordering", value="country asc, city asc")) private List<ContactInfo> contacts = new List<ContactInfo>(); In unowned relationships, "owner" object contains collection of keys of "nested" objects, for example: @PersistenceCapable public class Author { // ... @Persistent private List<Key> books; Is order of keys preserved, if I use List<Key> collection in "owner" object for storing keys of "nested" elements? I could not find answer neither in JDO relationships article, nor in Data Classes article :(

  • CloseHandler<Window> and Window.ClosingHandler() working differently in IE

    - by stuff22
    It seems that CloseHandler and Window.ClosingHandler() are not working or are not triggering the events in the same way under IE as opposed to Firefox. Window.addWindowClosingHandler(new Window.ClosingHandler() { @Override public void onWindowClosing(ClosingEvent event) { event.setMessage(message); } Window.addCloseHandler(new CloseHandler<Window>() { @Override public void onClose(CloseEvent<Window> event) { //Window.alert("debug1"); if(recordId!=null){ DatabaseQueryServiceAsync dbQueryService = DatabaseQueryService.Util.getInstance(); dbQueryService.releaseRecordLock(recordId, new AsyncCallback<String>() { @Override public void onFailure(Throwable arg0) { } @Override public void onSuccess(String arg0) { } }); } } }); }); For example, the ClosingHandler under IE displays the message when I swap a panel within within my widget. This does not occur in Firefox. The CloseHandler doesn't seem to trigger at all when the window closes in IE, but does so in firefox. The interesting thing to point out there, is that when I put a Window.alert("debug1") message in the addCloseHandler() method it DOES run the callback below, but as soon as I remove it, the callback doesn't happen. In firefox it works and runs the callback in both situations. So, I'm basically pulling my hair out not really understanding what's going on. Any help would be greatly appreciated. Thanks.

  • Are there any reasons to make all fields and variables final?

    - by Roman
    In my current project I noticed that all class fields and variable inside methods are declared with final modifier whenever it's possible. Just like here: private final XMLStreamWriter _xmlStreamWriter; private final Marshaller _marshaller; private final OutputStream _documentStream; private final OutputStream _stylesStream; private final XMLStreamWriter _stylesStreamWriter; private final StyleMerger _styleMerger; public DocumentWriter(PhysicalPackage physicalPackage) throws IOException { final Package pkg = new Package(physicalPackage); final Part wordDocumentPart = pkg.createPart( "/word/document.xml", "application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml", "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument"); // styles.xml final Pair<Part, String> wordStylesPart = wordDocumentPart.createRelatedPart(...); ... } Are there any reasons to do so? p.s. As I know project is not supposed to be multithreaded (at least I've heard nothing about it).

  • How to force HtmlUnit to save page?

    - by booroondook
    Hello. I'm using HtmlUnit to click on a HtmlElement that triggers Javascript action: currentPage = ((HtmlElement) currentPage.getByXPath("//*[contains(@onclick, 'check();')]").get(0)).click(); The element is: <a href="#" onclick="check(); return false;"> The page returned is quite similar to the page, containing that element: same URL, mostly same HTML, but there are some minor differences in the HTML and HtmlUnit doesn't save the new page. I'm using HttpAnalyzer to sniff the traffic and I see that the Webclient correctly handles JS and send the right request. The response is also correct, but when I dump the contents of the currentPage to a file, I see that the actual page didn't change. How can I fix it?

  • Meta Search Engine Architecture

    - by Loki
    The question wasn't clear enough, I think; here's an updated straight to the point question: What are the common architectures used in building a meta search engine and is there any libraries available to build that type of search engine? I'm looking at building an "enterprise" type of search engine where the indexed data could be coming from proprietary (like Autonomy or a Google Box) or public search engines (like Google Web or Yahoo Web).

  • Struts2 Converting Enum Array fills array with single null value

    - by Kyle Partridge
    For a simple action class with these member variables: ... private TestConverterEnum test; private TestConverterEnum[] tests; private List<TestConverterEnum> tList; ... And a simple enum: public enum TestConverterEnum { A, B, C; } Using the default struts2 enum conversion, when I send the request like so: TestConterter.action?test=&tests=&tList=&b=asdf For test I get a null value, which is expected. For the Array and List, however, I get and Array (or list) with one null element. Is this what is expected? Is there a way to prevent this. We recently upgraded our struts2 version, and we had our own converters, which also don't work in this case, so I was hoping to use the default conversion method. We already have code that is validating these arrays for null and length, and I don't want to have to add another condition to these branches. Is there a way to prevent this bevavior?

  • Are memcached entries saved by the Danga client compatible with the Spy client?

    - by jigjig
    After saving a String value into memcached using the Danga client, I attempted to get the entry using the Spy client. The two String values are not the same. The Danga client retrieves a string with an additional empty char prepended to the string, therefore violating the equality condition. Danga: t,e,s,t,s,t,r,i,n,g Spy: ,t,e,s,t,s,t,r,i,n,g I also attempted to save a serialized Map using the Danga client and get the Map using the Spy client. The Spy client is able to only get a String form of the Map. The string contains binary values, as below: sr
