I wants to develop a UWP remote desktop viewer application. I had already gone through many tutorials but those are all of winform application and I can't port them into uwp. So that desktop can be viewed from windows 10 mobile. I have zero knowledge regarding this so anyone can help me from where should I start and also if someone having UWP remote desktop code so that I can understand its working easily.
I am afraid you cannot develop such application easily in the Universal Windows Platform. Microsoft has its own Remote Desktop app, but it is definitely using some APIs which are not publicly available for the connection to remote computer.
To develop such app you would need to capture / record the screen on desktop as well as capture all input and relay the input from the remote device to the source.
You could create the desktop side of the app using Windows Forms / WPF and connect to it remotely from a phone, which would just act as a display and would capture and send the user input to the desktop counterpart.
There is also a small chance you could implement the desktop app in UWP with the help of Brokered Windows Runtime components, but that would be very tedious work.
Once again however, developing this is a major task, which is more suitable for a team of developers.
I am new in Windows phone development application. I built an app package and use Application Deployment Tool deployed it to devices for testing. But a microsoft account only allows to deploy 3 devices in maximum. I tried The Chinese tool aiyingyong_pc to jaibreak the Windows phone but it not work. Are there any ways to deploy to many devices or any tools can jailbreak the Windows phone?
As far as I know, except for Samsung devices, there is no jailbreak available for Windows Phone 8 (only for Windows Phone 7).
According to Microsoft, you can increase the device limit if you open a support ticket: http://blogs.msdn.com/b/matthiasshapiro/archive/2012/12/14/how-to-register-more-than-3-windows-phones-for-development.aspx
Honestly, I've never tried and the article is more than two years old, so I don't know if it's still true.
Otherwise, the only workaround left is publishing the app as a beta. Though not as convenient, you'll be able to install it on as many devices as you wish.
On other windows operating systems, I could create a Windows Service that listens to TCP/IP for any communication (like a PBX for example) through sockets.
But, how would i handle this in Windows 8? Applications can't run there all the time and when Windows 8 Metro starts up, applications for the normal desktop aren't running.
I need this service to start up all the time in any situation as soon as the computer starts up...
I also need http://pcapdotnet.codeplex.com an open source project to analyze the network...
What's the best future proof practice in an enterprise environment?
I don't have any Windows 8 experience on me yet.
Try this: If you make your windows service depend on something like the computer browser or could be the workstation service. The net connection should be up then.
You have to code this dependency in (no sample on hand).
In a situation where you have the UI frontend built using the new Metro style of apps for windows 8, and would like it to communicate with a .NET application running on the desktop on the same local machine (e.g. a windows service app).
What forms of interprocess communication are available between the metro app and the desktop app?
Thanks to Pavel Minaev of the Visual Studio team, who has provided some initial info here in a comment, quoted:
According to Martyn Lovell, there isn't any deliberate mechanism for
that, and some that could be used for it are intentionally restricted.
Named pipes aren't there, for example, nor are memory mapped files.
There are sockets (including server sockets), but when connecting to
localhost, you can only connect to the same app. You could use normal
files in one of the shared "known folders" (Documents, Pictures etc),
but that is a fairly crude hack that necessitates polling and is
visible to the user. -- Pavel Minaev commenting on this issue
So failing normal approaches I was thinking of using web services or reading/writing to a database in order to get some form of communication happening, both of which seem like overkill when the processes are running on the same machine.
Is what I'm attempting here making sense? I can see a need for a metro app to be the frontend UI for an existing service which is running on the desktop. Or is it better to just use WPF for the frontend UI running on the desktop (i.e. a non-metro app).
I'm porting my existing project to Win8 right now. It consists of windows service and tray application which are talking to each other via NamedPipes WCF. As you may already know Metro doesn't support named pipes. I ended up using TcpBinding for full duplex connection.
This post describes what functionality is supported.
Sample of my WCF server that Metro client can consume is here.
Also keep in mind that you can't use synchronous WCF in Metro. You'll have to use Task-based wrapper which is only asynchronous.
And thank you for you question. I was good starting point for me :)
There were a number of questions like this at the end of a //build/ session I attended. Aleš Holeček, the exec who did one of the big picture sessions, came up out of the audience to handle them. Even if you're not a C++ developer, download that session and watch the Q & A. http://channel9.msdn.com/Events/BUILD/BUILD2011/TOOL-789C
Metro apps can't count on desktop apps or services being installed on the machine. And desktop apps can't count on Metro apps running since they can be suspended any time. You need to start thinking differently. Listen to Aleš on this one.
Take note that with Windows 8.1 Update, communication between Windows Store apps and desktop components written in C# for .NET 4.5+ is now officially supported for side-loaded applications in Enterprise scenarios:
Brokered Windows Runtime Components for side-loaded Windows Store apps
To quote:
Recognizing that critical business functions and rules are embodied in existing software assets and that enterprises have a wide variety of scenarios for which the new application style will be highly productive, the Windows 8.1 Update includes a new feature called Brokered Windows Runtime Components for side-loaded applications. We use the term IPC (inter-process communication) to describe the ability to run existing desktop software assets in one process (desktop component) while interacting with this code in a Windows Store app. This is a familiar model to enterprise developers as data base applications and applications utilizing NT Services in Windows share a similar multi-process architecture.
Although implementing this approach is a bit on the complicated side initially, it allows for deep integration across Windows Store and desktop components. Just keep in mind that for the time being, it won't pass public Windows Store certification.
There is an article on InfoQ about how to build loosely coupled Metro apps with protocol handlers. This is something which has been supported by Windows for a long time and one could foresee an desktop application register itself as a protocol handler and maybe the metro application can communicate through this mechanism.
I have no idea if this is possible, but it might be interesting to check out.
Christophe Nasarre has blogged about a rather hacky way to do it using local files. The result is communication between desktop app/windows store app (referred to as DA/WSA in the blog), without having to switch between the UI of the two apps. He also blogged about another less hacky technique involving protocol handlers.
Note that having a WSA which communicates with a DA is explicitly forbidden by the store App certification requirements
Windows Store apps must not communicate with local desktop applications or services via local mechanisms, including via files and registry keys.
... but it restricts "local mechanisms" only. So I guess one can build a web service for routing the communications.
If you think that you can make an additional manual cmd operation,
you can try :
X:/> CheckNetIsolation.exe LoopbackExempt –a –n=<packageID>;
CheckNetIsolation.exe is included in winRT install, so there is nothing extra to be installed.
I tried it: it works, even after package updating.
As shown on: http://msdn.microsoft.com/en-us/library/windows/apps/Hh780593.aspx
Here it is explained how to find out the packageID for your app: http://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/82bad7d4-d52b-4731-a396-13ab9004c1cc/how-to-get-the-appid-of-a-metro-style-app-
It is possible to communicate on the same machine from Metro app to desktop app using local service.
I've implemented some time ago simple "proof of concept", how to bypass the WinRT sandbox using local service. It still needs some kind of "social engineering" or direct guide for installing the service, but anyway, it is possible.
I'm not sure though about the certification rules about "local service" communication when adding such app to Windows Store.
Sample here
By design Metro application cannot access underlying PC directly, only using WinRT API and available capabilities. But when you create back-end service for accessing the PC and all data there, it's basically no longer running in sandbox.
The only "problem" is that user must manually install this back-end service, but that won't be a problem using some "social engineering":
User downloads "PC browser" Metro app, user can browse all pictures, music and videos, using WinRT API, but the app also shows message at the bottom:
"Download our PC browser powerpack and browse your entire PC, for FREE"
User is redirected to web page, from where user can download classic desktop installer containing "PC browser" back-end service for accessing files on users entire PC. Once this desktop service is installed, the Metro app can detect it and use it for browsing the entire PC. User is happy, but the WinRT sandbox is compromised.
Of course this won't work on Windows 8 ARM tablets. Using this workaround it could be even possible to build Metro app clients for classic desktop apps like antiviruses, torrent/P2P clients, etc.
Maybe I missed the point but when activating the Private networks capability I can connect to a local running (http) server using the local IP address (not localhost). This enables my scenario where a winrt app communicates with a wpf desktop app
I am using .NET CF 2.0 with C#.
I need to create Policy enforcement application, which restricts backlisted application installation on windows mobile devices. How can I get notification for new application installation with an option to close the installation. I also need to get notification when someone uninstalls my application with an option to close the uninstall process.
Policy enforcement on Windows Mobile can be tricky. I'd recommend not trying to do this yourself if possible.
I've had success with the SPB Kiosk Engine in the past and found it much simpler than locking down the device yourself. Previoulsy I've only been able to lock down specific devices with software from the device manufacturers.
To detect installation of other apps you would need to create an app/service to monitor installed applications.
There isn't a way to detect/prevent uninstallation without use of another proces to monitor this. Even then I'd expect it to be VERY tricky.
