I have found this in documentation:
http://developer.blackberry.com/native/reference/cascades/bb__system__securityperimeter.html
but it just lists possible security perimeters. How do I get current security perimeter for my app?
I have found two methods to do this:
you can check your application's path for "-enterprise", for example this app is installed in "work space":
"/accounts/1000-enterprise/appdata/com.example.Test.testDev_nEncryptionb8c278e8.entr/data"
you can check content of PERIMETER environment variable. Possible values are "personal" and "enterprise".
These methods are not officially supported.

I built a virtual filesystem (not a namespace extension) for Windows which acts as a frontend of our document management server consisting of files and folders. In order to be able to display some metadata of the DMS objects in Windows Explorer as additional selectable columns, I successfully provided properties to the Windows Property System by implementing a COM Property Handler. Wheras normal property handlers focus on specific file types for which they feel responsible, my Property Handler adds properties to all files regardless of their type. Because Property Handlers can only be registered on the file type level, I registered my handler for about 30 types under
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\PropertyHandlers\<.Extension>
However, I did not manage to register the Property Handler for folder objects. Since all objects in our file system are virtual I build the property store (IPropertyStore) by implementing IInitializeWithFile instead of IInitializeWithStream. The properties are requested from our DMS with the path of IInitializeWithFile acting as key and were not read from an objects content. This concept would work for folders as well.
For getting called on folders I tried to associate the handler by registering under different well known identifiers like Folder, Directory, AllFileSystemObjects and * instead of the file extension without success.
I also didn’t find anything in the MSDN documentation regarding this aspect.
Is there a way to register a Windows Property Handler on folders? Or is there some other way to add custom columns to folders in Windows Explorer?
I'm not sure if it is possible to do this.
Property handlers are clearly not the right approach, they are system wide and there can only be one per file extension. They should only be implemented by the software that "owns" the file extension and can parse the file to extract properties.
The old column handlers would have been your best bet (IMHO) but they are officially dead and you already said you can't use them.
Have you considered creating a namespace extension? Either as a root item somewhere (Desktop or My Computer) the way My Documents used to work in 2000/XP or maybe something more along the lines of how OneDrive works?
I'm not sure if desktop.ini files work in the root of a drive but it might be worth looking into. You would then find yourself in the poorly documented land of [.ShellClassInfo] and its CLSID, CLSID2 and UICLSID members. The general idea would be to act as a IShellFolder proxy on top of the "real" IShellFolder so you could create a multiplex property store. I think there are some (undocumented?) property keys you can override to change the folders default columns and tooltips as well.
There is also something called a delegated folder that allows you to play with nested PIDLs but the documentation is once again pretty useless so I'm not sure if this is something worth looking into.
A 3rd option is to pretend to be a cloud storage provider. I don't know if this gets you any closer to your goal and you would still have to implement some NSE bits to get to the point where you can layer yourself on top of the underlying IShellFolder. This feature is rather new and only documented to work on Windows 10.
The inner workings of how Explorer/IShellBrowser is connected to the IShellFolder/IShellView is one of the least documented parts of Windows. There are hundreds of undocumented interfaces. Explorer gives DefView special treatment leaving other 3rd-party implementations out in the cold.
My feeling is that there is no clean solution to implement this on top of a drive letter but you might get lucky, if Raymond Chen drops by he might have some tips for you...
What's the best practice when you have dependencies that you want to be able to configure when creating a PowerShell module in C#?
My specific scenario is that the PowerShell module I am creating via C# code will use a WCF service. Hence, the service's URL must be something that the clients can configure.
Is there a standard approach on this? Or will this be something that must be custom implemented?
A somewhat standard way to do this is to allow a value to be provided as a parameter or default to reading special variable via PSCmdlet's GetVariableValue. This is what the built-in Send-MailMessage cmdlet does. It reads the variable PSEmailServer if no server is provided.
I might not be understanding your question. So I'll posit a few scenarios:
You PS module will always use the same WCF endpoint. In that case you could hardcode the URL in the module
You have a limited number of endpoints to choose from, and there's some algorithm or best practice to associate an endpoint with a particular user, such as the closest geographically, based on the dept or division the user is in, etc.
It's completely up to the end user's preference to choose a URL.
For case #2, I suggest you implement the algorithm/best practice and save the result someplace - as part of the module install.
For case #3, using an environment variable seems reasonable, or a registry setting, or a file in one of the user's profile directories. Probably more important than where you persist the data though, is the interface you give users to change the setting. For example if you used an environment variable, it would be less friendly to tell the user to go to Control Panel, System, Advanced, Environment, User variable, New..., than to provide a simple PS function to change the URL. In fact I'd say providing a cmdlet/function to perform configuration is the closest to a "standard" I can think of.
I need to determinate which agents and daemons are disabled on my OSX. Each process has plist file with parameters. I assume "Disabled" key is responsible for that. But not all agents/daemons has this value. So if property list doesn't contain this paramater it means it's disabled or enabled? I didn't find any info regarding default value for this item.
Please provide a reference to apple's documentation which proof it.
The "Disabled" keys in each LaunchDaemon file can be overridden by an entry in /private/var/db/launchd.db/com.apple.launchd/overrides.plist, and there's a similar system for LaunchAgents in /private/var/db/launchd.db/com.apple.launchd.peruser.userID/overrides.plist. I don't think Apple has documented this anywhere, which means that you are not expected to interact directly with these files, just use launchctl. It also means they're subject to change (i.e. it didn't always work this way and might change without notice in a later version of OS X). Also, the file for LaunchDaemons is only readable by root.
I found Worklight JSONStore has no size limit by Worklight runtime.
Does WL JSONStore API return error/error code if you add to collection and hit the size limit of your mobile device?
Yes, you should get an error, but it will be a generic one like PERSISTENT_STORE_FAILURE (-1). I recommend testing this as part of your regular unit, funcional, etc. tests and QA process for your application. Report back if you see something unexpected.
Recently I answered a similar question "Can the JSON offline device store be size restricted?". I'll add my answer here because I believe it could be helpful.
While this functionality is not baked into the core API, it should be fairly straightforward to implement.
JSONStore has an enhance method you can use to add functions to the JSONStoreInstance prototype. There's an example inside that should help.
Cordova has a File API
Note: "size: The size of the file in bytes. (long)"
JSONStore stores its data here:
iOS: [app]/Documents/wljsonstore/jsonstore.sqlite
Android: /data/data/com.[app-name]/databases/wljsonstor/jsonstore.sqlite
I talked a bit about that file in these StackOverflow answers:
What are the recommended ways to debug Worklight applications?
JSONStore difference between 'number' and 'integer' in searchFields
Check the file size of jsonstore.sqlite using Cordova's File API before you add more data to your JSONStore collection.
Basically you would do something like this:
if(checkFileSize(collection.name+'.sqlite') < LIMIT){
collection.add(...);
}
Using enhance you can wrap that logic into its own method (e.g. collection.addWithSizeCheck(....)) that checks the file size and calls collection.add(...).
Note that the default username is jsonstore, hence jsonstore.sqlite. If you pass a username to init it will create a new .sqlite file with that username.
I tried using MULTI_MODE_PROCESS above API Level 11. But still I am not getting updating values in activity and values were updated in remote service. I am not able to share preferences in remote service and activity even in froyo,ginger bread versions.Is this a bug in Android ? Any solution we have for this ?
Without code, it's not clear exactly what you're doing, but my guess is that you did the same thing I did at first: simply change your existing call to getSharedPreferences() to use MULTI_MODE_PROCESS and expect synchronization. That's not enough; you also must call getSharedPreferences() again (with the multi-process flag) before accessing the SharedPreferences that may have been changed by another process.
