sandbox

Sorry for that millionth question on autorenewable subscriptions, but i don't get it. I've done everything as describet in Apples In-App Purchase Guidelines but it didn't solve the problem. My problem is that i have created autorenewable subscriptions but they won't be autorenewed. I've create a Payment Transaction Observer class, which implements the SKPaymentTransactionObserver interface. This class will be installed as a paymentObserver at Application startup in the viewDidLoad: method. PaymentTransactionObserver *observer = [[PaymentTransactionObserver alloc] init]; [[SKPaymentQueue

I'd like to write a sandbox virtual machine for executing a compiled program. My goal is to isolate that program from the rest of operating system and control its execution so that it can't do anything harmful to a host computer. I assume that: executed program is compiled to Portable Executable format and it's in machine code, not in any kind of byte code or for CLR, executed program is not allowed to communicate with peripherals like printer, scanner, and doesn't use any GUI, executed program's main task is to process some data stored in a local file (eg. calculations), and put its results

I'm trying to write a simple judge that will compile and execute user submitted c files. I found libsandbox and a question here on stackoverflow. I have installed the python module and as per the instructions I'm trying to run a hello world program written in C ➜ sandbox git:(V_0_3_x) ✗ ./hello Hello World% ➜ sandbox git:(V_0_3_x) ✗ python sample2.py hello result: RF cpu: 2ms mem: 288kB As you can see, when I run the program in the sandbox I don't get any output. It'd be great if someone could tell me how to correctly use it. The sample code of libsandbox forbids system calls for file

I have an android app which uses sharedPreferences . I run the app in my android device using Eclipse I would like to pull the entire sandbox from the device to desktop so that I can manually see the contents of the sharedPreferences. I clicked DDMS and clicked FileExplorer and saw data folder But its empty. Any help is appreciated ! Thanks in advance ! If device is rooted may be it's possible. But in general you can not retrieve the sandbox of your app from your device to pc. But you can achieve your goal which is getting the sandbox of your app by running your app on Android Virtual Device

去年5月的时候，Jerry曾经写了一篇文章：使用Java程序消费SAP Leonardo的机器学习API，而最近另外做的一个项目，需要在Web应用里做同样的事情。 因为有了前一篇文章的铺垫，避免了很多重复的工作量。本文还是选择使用SAP Leonardo里的一个Product Image Classification API，即给定一张产品的图片，该API能识别出此产品的类别。 再回顾下这个API的功能：该API的模型是由SAP基于大约5万张Icecat图片训练而成，能区分29种不同的类别，这些类别具体罗列于官方文档上，比如电脑显示器，数码相机，外部存储设备，键盘，液晶电视，手机充电器，笔记本和其他外设等等。如果我们消费这个API时指定的图片代表的产品不属于这29种类别之一，API的表现如何？先卖个关子，文末解答。 关于如何在api.sap.com里找到这个API并且在API console里测试，请参考Jerry之前的文章：使用Java程序消费SAP Leonardo的机器学习API。 这里假定我们已经找到了该API，点击进入明细页面，将API Key复制下来，后续的UI5应用需要使用到。 然后进入SAP云平台的Neo环境。Jerry这个练习，使用免费的SAP Cloud Platform Neo测试环境即可。 在Service列表里找到WebIDE—

I'd like to sandbox a native code and use hooking of WinAPI and system functions to block or allow this program to perform some operations like reading/writing files, modify Windows registry, using an Internet connection. Is it a good and secure way to do so? How difficult would it be for that program to bypass such a security layer? +1 to Hans, however if you are really into it then I can recommend Easyhook . I have personally used it successfully in Win XP, Vista and 7. I don't know how bypassable it is but other alternatives do exist - madSHI hooks, and, if you want to go the official way,
