currently im developing a UWP Kiosk app. This app needs to print to a PosPrinter (EPSON TM-T20II) which is connected via ehternet to the network, The app runs in another pc connected with wifi to the same network. I have created the app using a DevicePicker class just like this example from Microsoft
PosPrinter c# configuration sample
in this example you open a poppup window that lists all your connected devices and filters the Printer. You can choose it and you will have a connection to that printer. The problem is when im using the app in Kiosk Mode in Windows 10 this windows with all the connected printers will not show up, and then i cannot stablish any connection. I have look into the set-multiple-kios apps option for windows 10, but i dont know how to stablish a path to the class known as DevicePicker to allow his functionality with my Kiosk app.
DevicePickerClass
Multiple-Kiosk-Apps
I have also tried to use PosPrinter.GetDefaultAsync() method to get the Printer directly but it always returns null, i also added the deviceCapabillities in my appxmanifest.xml
So if anyone could provideme with a hint or something i will be very grateful.
I found a solution by using the class FindAllAsync(DeviceClass), this return a collection with all connected devices belonging to that DeviceClass(in my case PosPrinter), after that i just use the Deviceinformation.id to pair the device with my program, like this: Posprinter.FromIdAsync(String deviceId), This way the device picker wont appear, so the Kiosk App will just find the Device and then will pop up a permission asking to Allow the device or not.

Context: I'm working on a Windows 10 app that will allow users to quickly connect to a Bluetooth device. Because the native API is difficult to work with, I'm using the 'In The Hand' library. Anyway, back to the point: whenever I make a connect request. Before allowing me to connect, I receive this Pair a device notification.
I'm wondering if I can set Windows to automatically accept this permission for connecting the device. Is there a method in the Windows API that I can use to accomplish this?
Here is the link to the code: https://github.com/hasham7861/bluetooth-le-experiment/blob/master/Program.cs
In the picture I make a connect request to a bluetooth headset and then I get the notification on the bottom right, and only if I click allow to pair device then it pairs the device.
I hope this link helps you.
I apologize in advance if I misunderstood the question or if the data were meaningless

I am developing a survey designer application in .NET C# which exports the surveys to a file which is sent to android devices. The android device will parse the survey file and show it in the survey mobile app.
Now, I want the user to be able to preview in the .NET application, so they can have an idea of how the survey will look in the android device by displaying the application in an android emulator. Furthermore, I want the emulator to be shown inside a windows form or panel.
My question is: is it possible to show the android emulator inside a winform application and is it possible to communicate with it? In other words, is there any APIs or extensions for Android Emulator in .NET framework?
I have searched the internet for the topic but most results talk about communicating with the emulator via TCP port and launching the application by creating a new process in the .NET app.
It is important to me to be able to display the emulator inside my application since I do not want to deploy multiple applications to my clients.
You can access a Hyper-V instance programmatically using its WMI provider. The Hyper-V instance can run without visible window to the user, and you can send mouse clicks & keyboard input, then take a screenshot.
But, it seems to be infinitely easier and lighter to just replicate the layout logic from the Android app in your C# app. If you went with the Android Emulator route, you're hosting a minimum 512 MB process and all the CPU & GPU usage involved.
I’m looking at creating a stand-alone application that scans several bar codes and at the end prints a receipt. I’m trying to understand from a developer prospective if there are standard calls to print via Windows CE.
The yet unspecified device would support at least Windows CE 5 up to a Windows Mobile 6/6.5. These would be a Motorola Symbol/Datalogic type hand held scanning terminal. The application would be used on whatever device we chose, not a broad range of products.
I’ve seen third-party libraries listed. Are these still relevant with more modern Windows Mobile releases?
I can send the specific codes to a printer outside of a printing system, but I don't want to go that route if printing is can be done "normally."
I expect to use VS 2005 or 2008 with C# depending on the model's support.
There is no printer support on Windows CE devices. What we've successfully done is to connect a Zebra receipt printer to the device via Bluetooth and send ZPL code directly to the COM port emulation. We were able to print on that device like this.
There is, however, no standard way that I know of.
While I'm not sure what more detail I could add, I'll try my best to describe what we did:
We had a little Windows CE industrial device (while I think it was a Datalogic device, the process should work with other devices, too) with Bluetooth support and a Bluetooth receipt printer that was capable of understanding the Zebra printer language (ZPL).
We connected the printer to the device via Bluetooth so that we could access the printer via a "Bluetooth COM Port". From then on, we were able to send ZPL code to the printer from our own applications and have the printer print what we sent, just as if the printer was directly connected using a serial cable.
In our application we had a little ZPL template into which we filled the information required. The user was then able to walk around with the mobile device, fill in forms and print labels.
The only catch was to re-enable the Bluetooth pairing after the scanner had gone into suspend mode, but I guess that's something you have to figure out depending on the device types - maybe there are even settings to have the connection re-established on your device.
I am trying to automate the application developed in Windows CE. I have created a simple Form consisting of Button and TextBox.
I run the application with the Pocket PC 2003 Emulator and once i record the test, it is able to automate the process like it can click the Button and using the keyboard on the simulator, it can also type in the textBox.
Now my concern is to validate the things like i want to get the TextBox as a control in my client application and want to validate the text inside it.
With CodedUI, I am unable to "Add Assertions" because the focus does not go inside the Emulator like below
Now, the window of the Emulator shows its been developed in the MSAA technology, i want to add verification points in my test and in order to do that i need to have programmatic access of the controls in the Emulator.
Please guide.
The emulator is a virtual machine, meaning that to your PC it's a completely separate machine. The host PC doesn't have access to the windows or controls of the hosted machine in any way. You could probably script some sort of location based output to simulate clicks onto the VM, but there's no way you can get a windows handle and do things like put text into or read text out of a control. Your better off creating a test proxy that runs on a device (could be the emulator or a physical device) and communicate with that proxy via network, RAPI, remote tools framework or something along those lines.
As a minor project in my degree I would like to communicate mobile and pc .I am interested to communicate through bluetooth is it possible to do so in c#?
If possible please provide me list of application or hardware i would requiere in order to do so.
thanks in advance
If (and it's a big if based on the lack of information in your question) you mean "How do I write an app on my PC, using C#, that can communicate with a Windows Mobile device that is connected to my PC via ActiveSync or WMDC" then the answer is RAPI. A free, open-source managed wrapper for it is here.
Yes its possible if its with windows mobile phone or pocket pc with bluetooth. You need a bluetooth enabled computer and mobile phone. For dev you need to download the windows mobile 6 sdk.
Then developing of the communication between desktop app and mobile phone app, you can use the 32feet.Net is open source.
When you download it and installs (well it unpacks to program files folder) you will have the dll that you make reference to in Visual Studio. Also you will get some sample apps. One of them is a Bluetooth Chat that works in Desktop, Pocket PC and SmartPhone.
Another option you could use is set up a web service that acts like an intermediary between the device and your machine. One huge benefit of this is that no longer are you bound by the distance requirements of bluetooth.
Of course if you're trying to build some sort of proximity service (do z when item x is 3 meters from item y) then bluetooth is probably the way to go.
