First of all, there are 3 questions here, here and here in stack overflow, but I couldn't find any resourceful help there. I have a biometric device ZKTeco (Model tx628). Task is very simple, just to read the thumb impression from this device. I am working on visual studio 2015 windows form application. I've downloaded the sdk from the manufacturer company's website. but cannot trigger any of them. they don't even connect with the device. I could connect the device through usb connection. but this doesn't work every time (I have no idea why. though its my first time working with device and dll). I might have missing something. please enlighten me with any suggestion, link or something. *yet I didn't find my device name on their website. I have found a solution there, but this didn't worked on mine.

I am currently attempting to deploy an app to a Windows 10 tablet running the Creator's Update, over my local network. When I select remote machine and enter my debug settings, I can discover the tablet on my network, and get its address and Authentication mode automatically.
However, when I try to deploy, I get this error:
DEP6957 : Failed to connect to device using Universal Authentication. Please verify the correct remote authentication mode is specified in the project debug settings. 0x8007274C: The network event being waited on triggered an error.
As far as I can tell from the documentation that I've read, this process should be more or less plug and play since the Creator's Update, can anyone explain what I might be doing wrong, or what might be going wrong?
Listed here are my debug settings currently in use.
Update: Since its not the solution I was looking for, I'm not adding it as an answer, but if anyone comes across this looking for a fix and no one has suggested one, the way I ended up working through this is just downloading the remote debugger to the tablet and running the old method for C# apps. I never did find out why the UWP method didn't work.
I'm currently working on getting a Leonardo device recognized and communicating with my app over a serial port in C# for the Windows 8 App Store. I'm using http://msdn.microsoft.com/en-us/library/windows/hardware/dn312121(v=vs.85).aspx#step2 as a guide, in conjunction with http://code.msdn.microsoft.com/windowsapps/USB-CDC-Control-sample-5ba19caa to guide me.
I'm having problems however in the sense that my Arduino device isn't showing up despite me entering my PID/VID and Class/Subclass/Protocol so I feel I'm missing some steps and was hoping someone that has experience with this could point me to a more specific/granular example.
My device is an Arduino Leonardo and I'm running windows 8.1 using Visual Studio 2013 Ultimate, code is in C#
Any help is appreciated!
Just general thoughts on regular windows applications (not aware of W8 AppStore):
Might help or might not, in the second case, sorry for wasting your time...
To get a "regular COM" device in Windows, without any additional drivers, you should make the device appear as USB Communication Device Class (aka CDC) - this is, among others, done via the appropriate class/subclass/protocol. The VID/PID don't care. This means the device should provide CDC/ACM USB descriptors to the enumerating USB host (windows) and implement the required endpoints and commands - supposedly there is already something existing for your board and you downloaded the firmware to it, right? You might want to try to connect such configured device to windows and after successful enumeration, new COM port should appear. If you program regular application, you just connect to such COM port via SerialPort class instance, no matter it is provided via USB subsystem... If this works, you should be able to start the AppStore part (where I have no clue how to help).
I'm just going to answer this as not currently possible. I ended up writing a desktop WPF application using metro UI/UX guidelines. Between that and ClickOnce deployment the store app feel is fairly well recreated, despite the store being ideal.
I sincerely hope that Microsoft decides to support this in the near future, the Metro SDK is really nice and I would love to eventually port it.
Hello guys I really have a big problem. Everytime I try to consume a webservice from an emulator, I always receive the message "Unable to connect to remote server". I already tried installing mobile device center and cradle the emulator. I literally tried doing all the stuff I see on the internet but no success. Hope you have new suggesion. Thanks in advance! By the way even my professor cant fix this problem LOL
Ensure, that you're connecting to the My Work networks in control panel, not the My ISP and craddle the emulator with the emulator device manager (you'll find it under Tools in Visual Studio 2008). Verify, that you can access your webservice from the mobile version of IE. I'm currently not at work, so I can't give you a more detailed description.
I want to create an application that can give me a description of all the softwares and hardware installed on a computer that is connected through a Local Network.
In Hardware Description - I want something like the list shown in Device manager and in software description i want a list of all the softwares installed in remote pc as shown in "add and remove programs".
How should i start for this. What i need to implement. I havent used any API before so plz be little descriptive so that i can implement them.
I'd start with WMI (Windows Management Instrumentation), I know you asked for the answer to be 'descriptive' but your question opens a pretty big topic and there probably isn't a quick 1,2,3 type answer for it.
Are there any good api's or examples of communicating between two devices via WiFi?
I am programming an app for 600 window's mobile (version 5) devices. They occasionally will need to connect with another device and exchange info.
Each device connects to the internet via GPRS (using the phone line). I could do the communications via that, but it is slow and may not work in all locations (this app will be used nationwide).
Just as an FYI, I also plan to look into bluetooth, but the stack we get on our Symbol Devices (MC70) is the Stonestreet One stack (we cannot change that). It is a very difficult to use stack with no managed code API. Also, it requires manual setup to use. My users will not be very technically inclined.
If there is another way to communicate (ie via the WiFi connection) I would love that.
(Ideally, I would like to be able to programmatically turn on the WiFi, send/receive data and then turn off the WiFi (to save batteries).)
Any help/suggestions are appreciated.
Motorola (who have bought Symbol a few years ago) do release an Enterprise Mobility Developer Kit for .NET CF which also has some libraries for controlling the WLAN on a Symbol MC70. I have worked with this in the past and it seems to work very well. The SDK comes with the full documentation and some sample applications.
Here is an earlier question on this subject:
better way to communicate between ad hoc wifi windows mobile devices
... which suggests that this is at least possible.
As an alternative, if the devices have infrared ports, you could have them communicate that way (I think).
Update: just found this example:
http://community.opennetcf.com/articles/cf/archive/2008/06/09/exchanging-data-using-windows-mobile-windows-communication-foundation-net-compact-framework-and-exchange-2007.aspx
It looks like you can do peer-to-peer communications with it. It requires .Net CF 3.5, however.
Someone is welcomed to prove me wrong but, as far as i know, out of the box it has to be bluetooth. WiFi is for networks. If you setup each device to also act as an access point you could make this happen. So I am sure it can be done, but it's not a clear path.
I see other issue slike security as well, because a router would handle this and now each of the 600 devices would be an access point handling this security, i am just shooting from the hip now which is basically my long winded advice to not go that direction.
-update
maybe i am a bad answerer, I just thought this was a bad direction. You can google windows mobile wifi peer to peer. Here is one site that covers it.
