  • php: simplexml exception retry

    - by exceptionhandlingnoob
    I am querying an API using SimpleXML which will occasionally fail for reasons unknown. I would like to have the script retry up to 5 times. How can I do this? I assume it has something to do with wrapping the object in a try/catch, but I'm not very experienced with this -- have tried to read the manual on exception handling but am still at a loss. Thanks for any help :) // set up xml handler $xmlstr = file_get_contents($request); $xml = new SimpleXMLElement($xmlstr); Here is the error message I am receiving: [function.file-get-contents]: failed to open stream: HTTP request failed!

  • How to tell the MinGW linker not to export all symbols?

    - by James R.
    Hello, I'm building a Windows dynamic library using the MinGW toolchain. To build this library I'm statically linking to other 2 which offer an API and I have a .def file where I wrote the only symbol I want to be exported in my library. The problem is that GCC is exporting all of the symbols including the ones from the libraries I'm linking to. Is there anyway to tell the linker just to export the symbols in the def file? I know there is the option --export-all-symbols but there seems not to be the opposite to it. Right now the last line of the build script has this structure: g++ -shared CXXFLAGS DEFINES INCLUDES -o library.dll library.cpp DEF_FILE \ OBJECT_FILES LIBS -Wl,--enable-stdcall-fixup EDIT: In the docs about the linker it says that --export-all-symbols is the default behavior and that it's disabled when you don't use that option explicitly if you provide a def file, except when it doesn't; the symbols in 3rd party libs are being exported anyway. EDIT: Adding the option --exclude-libs LIBS doesn't keep their symbols from being exported either.

  • Get expiration time of a memcache item in php?

    - by Jonatan Littke
    Hey. I'm caching tweets on my site (with 30 min expiration time). When the cache is empty, the first user to find out will repopulate it. However, at that time the Twitter API may return a 200. In that case I'd like to prolong the previous data for another 30 mins. But the previous data will already be lost. So instead I'd like to look into repopulating the cache, say, 5 minutes before expiration time so that I don't lose any date. So how do I know the expiration time of an item when using php's memcache::get()? Also, is there a better way of doing this?

Any idea?

  • Efficient persistent storage for simple id to table of values map for java

    - by wds
    I need to store some data that follows the simple pattern of mapping an "id" to a full table (with multiple rows) of several columns (i.e. some integer values [u, v, w]). The size of one of these tables would be a couple of KB. Basically what I need is to store a persistent cache of some intermediary results. This could quite easily be implemented as simple sql, but there's a couple of problems, namely I need to compress the size of this structure on disk as much as possible. (because of amount of values I'm storing) Also, it's not transactional, I just need to write once and simply read the contents of the entire table, so a relational DB isn't actually a very good fit. I was wondering if anyone had any good suggestions? For some reason I can't seem to come up with something decent atm. Especially something with an API in java would be nice.

  • Tool to monitor IE performance running JavaScript

    - by StefanE
    Hi, Company I work for are one of the largest betting companies in Europe and the website has thousands of lines of JavaScript on all our pages. Lately Internet Explorer versions earlier than version 9 are running painfully slow and I want to be able to monitor what parts of a page load (including scripts) that are slow. I know that IE are slower in general and has DOM API issues etc. What I want to accomplish is a way to quickly identify slow parts and see if we can replace the code with IE specific code that will render with higher performance. Cheers, Stefan

  • Get a list of Android phone contacts only on Eclair and above?

    - by Rob Kent
    I want to show the user a flattened pick list of all their contacts phone numbers and it must work from versions 1.6 up. I have read the related questions on SO and the Android documentation for Eclair (http://developer.android.com/resources/articles/contacts.html#legacy). The problem is, even splitting my code into a factory class and specific implementations does not work for me because using Contacts.CONTENT_URI only shows contacts not individual numbers. What I need is this for version 1.6 Intent intent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI); startActivityForResult(intent, REQUEST_PICK_CONTACT); And the equivalent for 2.0 and above. Even if I get their example to work, by building against the 2.1 API am I not stopping my app being visible on the Market to users with earlier versions of the OS? I can't launch it against a 1.6 emulator, for example.

  • Turn Bluetooth On and Off in Andriod 1.5 (SDK level 3)?

    - by pcm2a
    There are tons of pay and free bluetooth toggles on the market that work with Android 1.5 (SDK level 3). The problem is there is no visible API for this! Does anyone have any working code snippits on how to enable and disable bluetooth that works on Android 1.5? I assume you must have to use some kind of reflection for it. There are some examples over on anddev.org, but they only work with Android 1.1 or lower. This is for Android 1.5 (SDK level 3) and not Android 2.0 or greater. In Android 2.0 or later Google added easy to use APIs.

  • Google Calendar title displayed incorrectly

    - by Don
    Hi, I'm creating 2 Google calendars via the Java client API using the following Groovy method: private CalendarEntry createGoogleCalendar(User user) throws ServiceException { new CalendarEntry().with {calendar -> title = new PlainTextConstruct(user.email) summary = new PlainTextConstruct("Collection calendar for $user.email") timeZone = new TimeZoneProperty("America/Montreal") hidden = HiddenProperty.FALSE def savedCalendar = googleCalendar.insert(CALENDAR_URL, calendar) log.debug "Created calendar with title '$savedCalendar.title.plainText' for '$user.email'" return savedCalendar } } The logs show: CalendarService - Created calendar with title '[email protected]' for '[email protected]' CalendarService - Created calendar with title '[email protected]' for '[email protected]' so it appears that all is well. However when I look at the 1st calendar on the Google website, the title is shown as [email protected], though the summary is correctly shown as Collection calendar for [email protected]. Strangely, the title and summary are both shown correctly tor the 2nd calendar. This only started happening today, and I'm pretty sure the relevant code has not changed. I'm totally stumped....

  • Backbone collection's URL depends on initialize function

    - by egidra
    I have a Backbone collection whose URL depends on the initialize function. When I create an instance of this Backbone collection, I pass in an ID to filter which instances of the model appear. Here is what the collection's code looks like: var GoalUpdateList = Backbone.Collection.extend({ // Reference the Goal Update model model: GoalUpdate, // Do HTTP requests on this endpoint url: "http://localhost:8000/api/v1/goal_update/?goal__id=" + this.goal_id + "&format=json", // Set the goal ID that the goal update list corresponds to initialize: function(goal_id) { this.goal_id = goal_id; console.log(this.goal_id); console.log(this.url); }, }); Of course, this doesn't work. this.goal_id is seen as being undefined. I guess because the URL is set before the initialization function is run.

  • handling activity destruction in multithreaded android app

    - by Jayesh
    Hi, I have a multithreded app where background threads are used to load data over network or from disk/db. Every once in a while user will perform some action e.g. fetch news over network, which will spawn a background AsyncTask, but for some reason user will quit the app (press back button so that activity gets destroyed). In most such scenarios, I make appropriate checks in the background thread after it returns from n/w i/o, so that it won't crash by accessing members of the activity that is destroyed by now. However some corner cases are left where crashes happen, because the background thread would access some member of activity that is now null. Do other Android developers have some generic/recommended framework to handle such scenarios? These are the times when I wish android would have guaranteed termination of all threads when activity destroys (in the same way that regular linux process cleans up when it's quit)... but I guess Android devs had good reasons for not exposing process lifetimes through the api.

  • Is it possible to use SWT on a Mac with Mac Java 1.6

    - by ?????
    The official Eclipse site seems to indicate this is not possible: https://bugs.eclipse.org/bugs/show_bug.cgi?id=216051 which says: Apple is not supporting the 64-bit carbon API. SWT is written using carbon so it must be 32-bit. Apple won't support 32-bit JDK 1.6. Therefore SWT won't run on JDK 1.6 (along with any other Java program that had natives that made carbon calls). Nothing we can do here other than port to cocoa (which has been started but is still in the early stages). Is this still true? (This bug report comment is from over a year ago.) Is there no way to write an SWT app that I can distribute and will run on any Mac unless the user installs an old/Sun VM?

  • What is the difference between remote procedure call and web service

    - by xiao
    Is there any clear definition about RPC and Web Service? A quick wikipedia search shows: RPC: Remote procedure call (RPC) is an Inter-process communication technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer explicitly coding the details for this remote interaction. Web Service: Web services are typically application programming interfaces (API) or web APIs that are accessed via Hypertext Transfer Protocol and executed on a remote system hosting the requested services. Web services tend to fall into one of two camps: Big Web Services[1] and RESTful Web Services. I am not quite clear what the real difference between the two things. It seems that one thing could belongs to RPC and is kind of web service at the same time. Is Web Service a higher level representation of RPC?

  • What issues carry the highest risk in a software project?

    - by Mehrdad Afshari
    Clearly, software projects are different from other industries in terms of many things like for instance, quality assurance, project progress measurement, and many other things. Unique characteristics of software projects also makes the risk management process unique. Lots of issues in a project might lead it to unacceptable delay or failure to deliver business value. They might even make a complete disaster in the project. What are the deadliest risk factors in a software project? How to analyze, prevent and handle them? Particularly, I'm interested in the issues that you can detect from the beginning and you should keep an eye on (for example, you might be told about a third-party API that the current application uses and lacks documentation). Please share your experiences if they are relevant.

  • Event handling to detect if user clicks a 'Like' button in XFBML page

    - by Simon_Weaver
    I have a Facebook connect app / canvas IFrame app which has a Like control for a fanpage. I'd like to detect when the user clicks the Like button to be able to display additional info (a discount coupon code). I'm using the latest Javascript API but the events that can be handled doesn't seem to include detection of social widget controls. The documentation for the Like Plugin doesn't show any events. However I know its definitely possible because if I have two Like buttons on a page they both instantly update each other if I like or unlike whatever it is.

  • Read Text From Windows Form

    - by omghai2u
    I would like, if for no other reason that an academic exercise, to be able to read text written to a form on a Windows Application. The program appears to be written in non-.NET, but in .NET terms, I think you would describe the program as having a Form with a Label and I would like to read the text from that label. I believe I can see that text being written to the screen with the User32!TextOut (and in other areas User32!DrawString) function. However, it would be nice if I didn't have to hook that function to get the information I'm looking for, but instead if I could just read it from the form directly. So, given a handle to a Window, is it possible to read the text that has been written to that window with functions like TextOut and DrawString using some similar API or other clever means? Or am I going about this the wrong way? Should I just hook the function and look for the text in every call and pray? Thanks!

  • SharePoint SLK and T-SQL xp_cmdshell safety

    - by Mitchell Skurnik
    I am looking into a TSQL command called "xp_cmdshell" to use to monitor a change to a the SLK (SharePoint Learning Kit) database and then execute a batch or PowerShell script that will trigger some events that I need. (It is bad practice to modify SharePoint's database directly, so I will be using its API) I have been reading on various blogs and MSDN that there are some security concerns with this approach. The sites suggest that you limit security so the command can be executed by only a specific user role. What other tips/suggestions would you recommend with using "xp_cmdshell"? Or should I go about this another way and create a script or console application that constantly checks if a change has been made? I am running Server 2008 with SQL 2008.

  • Is it possible to send an automated email with dynamic content in Rails

    - by Danny McClelland
    Hi Everyone, I am looking into the best way of doing the following: I have a model called Kase, and when a user creates a new case then are taken to the show view as you would expect. I am trying to work out what the best way of sending an automated email between those two events is. I would need to include in the email the content of a couple of the fields, ideally I am looking for a way of just typing out the email and adding the same snippets that are in the show view for each of the fields I need. I am using the Base App from Github so the email sending is already setup for the user authentication and registration, but I'm not sure where to begin. The reason I want to send the email is to create a new Case in our Highrise account, and I don't have a clue how to use the API. So I think the email sending is the easier way. Thanks, Danny
