• Is there any user-friendly way to deliver an In-app purchase subscription to multiple devices?

  - by mkvakin

  Hi everybody, Apple requires an in-app purchase subscription purchased on one device to be available on all devices associated with the user: “...subscriptions must be provided on all devices associated with a user. In App Purchase expects subscriptions to be delivered through an external server that you will provide. You must provide infrastructure to deliver subscriptions to multiple devices.” Is there any way to propagate a subscription to another device transparently without user having to create a server side user account and log in each time he needs to enable the subscription on another device? E.g. by reading a username from some kind of API and using it as a key on a server to store information about subscriptions. I tried to find an API for retrieving user account info but couldn't find any.

• PHP Launch Execute Files Concurrently

  - by Ozzy

  Hi all. Basically, I was doing some testing using apache bench. The file i was testing takes 2 seconds to execute (its optimised, it connects to an external server hence the slowdown) Basically I found that the more concurrent useres i emulated, the more executions of the file i could do per second. Is there anyway that i can do something like this in php? : <?php execute_file('file.php'); execute_file('file.php'); execute_file('file.php'); execute_file('file.php'); execute_file('file.php'); ?> That would execute the file 5 times but would NOT wait for the files to finish downloading so the above example would quickly call the 5 functions then exit. Im assuming somesort of timeout would be used?

• removing a line from a text file?

  - by Blackbinary

  Hi all. I am working with a text file, which contains a list of processes under my programs control, along with relevant data. At some point, one of the processes will finish, and thus will need to be removed from the file (as its no longer under control). Here is a sample of the file contents (which has enteries added "randomly"): PID=25729 IDLE=0.200000 BUSY=0.300000 USER=-10.000000 PID=26416 IDLE=0.100000 BUSY=0.800000 USER=-20.000000 PID=26522 IDLE=0.400000 BUSY=0.700000 USER=-30.000000 So for example, if I wanted to remove the line that says PID=26416.... how could I do that, without writing the file over again? I can use external unix commands, however I am not very familiar with them so please if that is your suggestion, give an example. Thanks!

• Caching for a Custom Repositiory Adapter for WebSphere Portal Virtual Member Manager

  - by Spike Williams

  I'm looking at writing a custom repository adapter to interact with Virtual Member Manager on WebSphere Portal 6.1. Basically, its a layer that takes a request in the form of a commonj.sco.DataObject and passes that on to an external web service, to get various information on our logged in users that is not otherwise available in LDAP. I'm concerned about the performance hit of going to a service every time we want to pull some permission from the back end. My question is, can the Virtual Member Manager handle caching of data going in and out of the custom repository adapters, or is that something I'm going to have to build into the adapter myself?

• Exception while trying to deserialize JSON into EntityFramework using JavaScriptSerializer

  - by Barak

  I'm trying to deserialize JSON which I'm getting from an external source into an Entity Framework entity class using the following code: var serializer = new JavaScriptSerializer(); IList<Feature> obj = serializer.Deserialize<IList<Feature>>(json); The following exception is thrown: Object of type 'System.Collections.Generic.List1[JustTime.Task]' cannot be converted to type 'System.Data.Objects.DataClasses.EntityCollection1[JustTime.Task]'. My model is simple: The Feature class has a one-to-many relation to the Tasks class. The problem appears to be the deserializer is trying to create a generic List to hold the collection of tasks instead of an EntityCollection. I've tried implementing a JavaScriptConverted which would handle System.Collections.Generic.List but it didn't get called by the deserializer.

• Is it possible to use AutoMapper to wrap methods?

  - by Woj

  I have two classes: public class TestClass1 { public int TestInt { get; set; } public void TestMethod() { // Do something } } public class TestClass2 { public int TestInt { get; set; } public void TestMethod() { // Do something } } I want to create interface that I can use for both classes. The easiest solution is to implement the interface on TestClass1 and TestClass2 but I don;t have access to the implementation of these classes (external dll). I was wondering if I can create new interface and use AutoMapper to map TestClass1 and TestClass2 to ITestInterface: public interface ITestInterface { int TestInt { get; set; } void TestMethod(); }

• Create a triangle out of stars using only recursion

  - by Ramblingwood

  I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration). The output needs to look like this: * ** *** **** ***** This code works with the iterative but I can't adapt it to be recursive. public void printTriangle (int count) { int line = 1; while(line <= count) { for(int x = 1; x <= line; x++) { System.out.print("*"); } System.out.print("\n"); line++; } } I should not that you cannot use any class level variables or any external methods. Thanks.

• iPhone check for a constant at runtime in universal app

  - by joshue

  I'm making a universal iPad/iPhone app which can use the iPad's VGA out connector to mirror the content of the app on an external screen. However, the iPhone does not have this functionality. given the following code, [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidConnectNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidDisconnectNotification object:nil]; I get this error on the phone at launch (works fine in ipad) "dyld: Symbol not found: _UIScreenDidConnectNotification" presumably because UIScreenDidConnectNotification doesnt' exist yet in 3.13. How do I check for this at runtime?

• some OVERLAPS using WSASend not returning in a timely manner using GetQueuedCompletionStatus?

  - by Geoffrey

  Background: I'm using CreateIoCompletionPort, WSASend/Recv, and GetQueuedCompletionStatus to do overlapped socket io on my server. For flow control, when sending to the client, I only allow several WSASend() to be called when all pending OVERLAPs have popped off the IOCP. Problem: Recently, there are occassions when the OVERLAPs do not get returned to the IOCP. The thread calling GetQueuedCompletionStatus does not get them and they remain in my local pending queue. I've verified that the client DOES receive the data off the socket and the socket is connected. No errors were returned when the WSASend() calls were made. The OVERLAPs simply "never" come back without an external stimulus like the following: Disconnecting the socket from the client or server, immediately allows the GetQueuedCompletionStatus thread to retrieve the OVERLAPs Making additional calls to WSASend(), sometimes several are needed, before all the OVERLAPs suddenly pop off the queue. Question: Has anyone seen this type of behavior? Any ideas on what is causing this? Thanks, Geoffrey

• Do you chat online for work purposes?

  - by JBB

  I've worked with folks who are chatting online with their peers, constantly batting around ideas. I've also worked with folks who adamantly refuse and think it's a waste of time. Are online live chatting forums of particular use to you? Why or why not? Internal to your company, or external and world-wide? Does your employer encourage or discourage their use? Update: I see some people are voting this question down, yet so far all the answers have been positive, if with some reservations. If someone has a strong negative opinion (I hate online chatting and think it should be banned etc.) I'd really like to hear why.

• Test Jboss JMS externally - outside of the application server

  - by bmatsliah

  Hi All, I'm pretty new to the JMS functionality. I need to test a remote JMS which is on Jboss 4.2.1. I want to develop an external test (e.g from a main class) which sends and receives messages to/from the app. server. (I do have full access to the remote server.) My questions are: 1) How do I send messages to the Jboss JMS? 2) Where is the information needed to send a message located on the Jboss? ip, port, queue, user, pw, ect. to set up the local messaging test. 3) Is there a way to config/ develop a mechanism on the remote JMS Jboss server that sends back acknowledgments to the sender (in this case)? I greatly appreciate your help. Thanks, Ben

• Best way to style GWT widgets in a library

  - by helios

  I'm developing some widgets into a library for internal use at the company I work for. I don't know what's the recommended way to style the widgets. There are at least these ways: use Widget.setPrimaryStyleName and let the user provide an external css. We use maven archetypes to build applications so we can provide default styles. Anyway I don't like it very much. use the GWT 2.0 CssResourceBundle. So we can compile the CSS into the module and it will be optimized (and it can be browser-dependant too). provide a module with the styling. Something like the default GWT themes. But I don't know how exactly this works. I want to: make the components as cohesive as I can (don't depend on externally included css's) leave open the door to modify styles (if I want to change the way some widget looks in a concrete application). What's your experience in this subject?

• Bypassing Windows Copy design

  - by Scott S

  I have been trying to figure out a way to streamline copying files from one drive (network or external in my case) to my main system drives. Short of creating a program that I will have to activate each time then choosing all the info in it, I have no really good design to bypass it. I have been wondering if there was a way to intercept a straight-forward windows copy with a program to do it my way. The basic design would be that upon grabbing the copy (actually for this to be efficient, a group of different copies), the program would organize all the separate copies into a single stream of copies. I've been wanting to do this as recently I have been needing to make backups of a lot of data and move it a lot as all my drives seem to be failing the past few months.

• How can you set a time limit for a PowerShell script to run for?

  - by calrain

  I want to set a time limit on a PowerShell (v2) script so it forcibly exits after that time limit has expired. I see in PHP they have commands like set_time_limit and max_execution_time where you can limit how long the script and even a function can execute for. With my script, a do/while loop that is looking at the time isn't appropriate as I am calling an external code library that can just hang for a long time. I want to limit a block of code and only allow it to run for x seconds, after which I will terminate that code block and return a response to the user that the script timed out. I have looked at background jobs but they operate in a different thread so won't have kill rights over the parent thread. Has anyone dealt with this or have a solution? Thanks!

• Convert XML to .plist

  - by Dror Sabbag

  Hey, I have an XML exported from Oracle DB, which will be downloaded into my application main bundle. i would like to convert this XML file into .plist file so i can assign the values into NSDictionary and NSArrays.. Is there a way to get this to work? or is there a better way to work with an external XML file? note that one of the fields in the XML is a full HTML content example: <main> <DATA_RECORD> <ID>ID1</ID> <NO>1234512</NO> <TYPE>NEW</TYPE> <TYPE_NO>0</TYPE_NO> <TEXT_ID>TEXT1</TEXT_ID> <TEXT><HTML>some html goes here</HTML></TEXT> </DATA_RECORD> </main>

• Mocking imported modules in Python

  - by Evgenyt

  I'm trying to implement unit tests for function that uses imported external objects. For example helpers.py is: import os import pylons def some_func(arg): ... var1 = os.path.exist(...) var2 = os.path.getmtime(...) var3 = pylons.request.environ['HTTP_HOST'] ... So when I'm creating unit test for it I do some mocking (minimock in my case) and replacing references to pylons.request and os.path: import helpers def test_some_func(): helpers.pylons.request = minimock.Mock("pylons.request") helpers.pylons.request.environ = { 'HTTP_HOST': "localhost" } helpers.os.path = minimock.Mock(....) ... some_func(...) # assert ... This does not look good for me. Is there any other better way or strategy to substitute imported function/objects in Python?

• Suggestions for VS+Resharper keyboard shortcuts on a Mac

  - by John Miller

  I just upgraded to a Macbook Pro as my development machine but still primarily develop .Net applications with Visual Studio and Resharper (via VMWare Fusion). By far, the biggest obstacle I'm running into is getting used to the keyboard layout change (ex. not being able to do ALT-Insert). Do any of you Windows-on-Mac veterans have any suggestions on how to ease the pain of transitioning (without moving to an external keyboard)? Are you changing mappings via VMWare's keyboard preferences? Or are you using something like AutoHotkey? Any other windows development tips for a Mac newb?

• How to force HttpWebRequest to use cache in ASP.NET environment?

  - by piotrsz

  In my ASP.NET app I use HttpWebRequest for fetching external resources which I'd like to be cached. Consider the following code: var req = WebRequest.Create("http://google.com/"); req.CachePolicy = new HttpRequestCachePolicy(HttpRequestCacheLevel.CacheIfAvailable); var resp = req.GetResponse(); Console.WriteLine(resp.IsFromCache); var answ = (new StreamReader(resp.GetResponseStream())).ReadToEnd(); Console.WriteLine(answ.Length); HttpWebRequest uses IE cache, so when I run it as normal user, data is cached to %userprofile%\Local Settings\Temporary Internet Files and next responses are read from cache. I thought that when such code is run inside ASP.NET app, data will be cached to ...\ASPNET\Local Settings\Temporary Internet Files but it is not and cache is never used. What I am doing wrong? How to force HttpWebRequest to use cache in ASP.NET environment?

• uint8_t and unsigned char linking error

  - by mnn

  I'm using template function: template<typename T> void func(const T& value) { obj->func(value); } where obj is object of class: void my_object::func(int64_t value) { ... } void my_object::func(uint64_t value) { ... } void my_object::func(uint32_t value) { ... } void my_object::func(uint16_t value) { ... } void my_object::func(uint8_t value) { ... } The problem is with uint8_t overload of my_object::func() override. Linker complains about unresolved external symbols to overloads, which should have unsigned char parameter. Should I replace uint8_t overload with unsigned char overload? Edit: Just now noticed, that linker complains about uint64_t and int64_t too. I compile on Windows using MSVC++ 2008 Express.

• Flash CS5 projects panel totally gone?

  - by Jesse

  So, I popped open up Flash CS5 just now, and I couldn't find my projects panel. I was working on a dual screen set up previously, so my windows were everywhere anyways (sans external). I switched over to a smaller screen workspace, and popped opened the projects panel. Oddly enough, the code snippets panel came up instead. So, I switched off the code snippets, and tried again. I've been trying different ways of opening this panel for about 15 minutes, and I'm totally stumped. Some thorough googling didn't present any relevant results, so, StackOverflow, I turn to you. Is this a known issue? is there a secret backdoor way to open this panel? Am I totally missing something?

• Linking to a C library compiled as C++

  - by Jacob

  I'm in linker paradise now. I have a C library which only compiles in Visual C++ (it probably works in gcc) if: I compile it as C++ code Define __cplusplus which results in all the declarations being enclosed in extern "C" { } So, by doing this I have a static library called, say, bsbs.lib Now, I have a C++ project called Tester which would like to call function barbar in declared in bsbs.h. All goes fine, until I try to link to bsbs.lib where I get the all-too-familiar: Tester.obj : error LNK2001: unresolved external symbol _foofoo And it always seems to be foofoo which cannot be resolved regardless of which function I call in Tester (barbar or anything else).

• How to integrate access control with my ORM in a .net windows form application?

  - by Ying

  I am developing a general database query tools, a .Net 3.5 Windows Form application. In order to make the presentation layer is independent of the database layer. I use an ORM framework, XPO from DevExpress. But, I have no access control function built in. I surfed Internet and I found in WCF Data Services, there is an interesting concept, Interceptor, which is following AOP(Aspect Oriented Programming). I am wondering who has such an experience to build access control in ORM. My basic requirement is : It should be a general method and controlled by users in runtime. So any hard coding is not acceptable. It could be based on attribute, database table, or even an external assembly. I am willing to buy a ready solution. According to the idea of AOP, an access control function can be integrated with existing functions easily and nearly not knowingly to the previous developer;) Any suggestions are welcome.
