I want to get a contact stored in windows phone device and save in .vcf (vcard format) but I cannot find any method for this functionality.
In msdn documentation the method ParseVcardAsnc does the reverse of what I need.
Is there any method in c# for what I am looking for ?
You need ToVcardAsync or ToVcardAsync(VCardFormat) methods.

I am developing a Windows Phone 8.1 Application and there is a need to get the Application Process ID from code. Any API with which I can get that?
You can use GetCurrentProcess followed by DuplicateHandle (and later CloseHandle) but I'm curious what you need it for... there's not much you can do with it in a Store app so maybe this won't complete your scenario.
Finally got the solution.
The Dll's for Desktop apps and Phone apps are different though the function names will be same.
When tried to import Kernal.dll lib in WIn Phone 8.1 and used p/invoke code, an exception, DllNotFoundException will be thrown. Instead in Win Phone 8.1 instead use "api-ms-win-core-processthreads-l1-1-1.dll"
To get the process ID in Win Phone 8.1 :
1)Create binding to WIN32 lib:
[DllImport("api-ms-win-core-processthreads-l1-1-1.dll", CharSet = CharSet.Unicode, ExactSpelling = false, PreserveSig = true)]
internal static extern uint GetCurrentProcessId();
2)Call the function:
uint id= GetCurrentProcessId();
For the complete set of Win Phone 8 supported API's see the MSDN link:

Basically I am PHP developer! and now I want to implement the push notifications for windows phone! So for this I have refereed many blogs and also started implement on this! but for demo purpose how I can get my device token and device specific type of my phone that having Windows 8.1 OS.
Is any GUI tool for getting this.
If you need the Device Token as follows-
Byte[] DeviceArrayID = (Byte[])Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("DeviceUniqueId");
string UniqueDeviceID = Convert.ToBase64String(DeviceArrayID);
Debug.WriteLine("Device ID - " + UniqueDeviceID
Also, if you need help regarding push notifications in Windows Phone apps, follow this link-
http://msdn.microsoft.com/en-us/library/windows/apps/hh202967%28v=vs.105%29.aspx
It also has a project for a simple webpage which can send notification to your device for testing purposes.
The following should work
object DeviceUniqueID;
byte[] DeviceIDbyte = null;
if (DeviceExtendedProperties.TryGetValue("DeviceUniqueId", out DeviceUniqueID))
DeviceIDbyte = (byte[])DeviceUniqueID;
string di = Convert.ToBase64String(DeviceIDbyte);
The above code will give you the device ID. You can use the string di to pass the Device ID to your web service to provide the user with push notifications.
Ive build the sample pjsip library for windows phone and successfully registered and made a call.
butproblem is audio is always on speaker phone,not on earpiece ,
can anyone help to make the earpiece the default audio route always ?
Thanks
Access to audio routes is only allowed when a "Windows Voip Call" is active. This is achieved by calling the NotifyCallActive method on the VoipPhoneCall object. The VoipPhoneCall object is returned via a call to the RequestNewOutgoingCall method of the VoipCallCoordinator class. I've tried integrating PJSIP into the Windows Phone 8 voip framework but PJSIP is not able to run in the background process. Still trying to figure that one out.
You can't with the PJSip sample. If you search in pjmedia_audiodev you'll discover a TODO tag.
Also, the sample does not manage VoIP calls, therefore you can route to the earpiece.
I hope this helps.
I'm new Windows Phone Universal App, I need to implement bar/pie chart.
Tried many dll, Metro UI, WinRtXamlToolKit and WinRtXamlToolKit.Controls.DataVisualization
These dll are not working.
Give me good idea to do this on Windows Phone Universal App. How to do chart programmatically.
Thanks
I believe the Telerik has some Chart libraries that cost money ( can't link though as stackoverflow only permits me to post 2 links ( less than 10 rep) ). I have not used it and it is in Beta version at the moment. Google "Rad Chart windows universal apps" and you can read about it.
When I have needed charts for universal apps i have used the Google Chart Tools. You can use https://developers.google.com/chart/image/ even though Google is not developing on it anymore. It is is freakingly easy to use if you do not want to spend time drawing your own Charts. With the API you can request a chart just through a http request. You can setup almost everything and it's really easy to use thanks to the well documented API.
Here is an example of a bar chart i made using the API.
http://chart.googleapis.com/chart?chtt=Karakterfordeling&cht=bvg&chof=png&chs=300x300&chxt=x,y&chco=0076A3&chf=bg,s,65432100&hxr=0,0,50&chxl=0:|2|4|7|10|12&chxr=1,0,20&chbh=40,0,10&chd=t:2,60,70,10,90
All the arguments are passed through the http request and you can set your Chart up using the Live Chart Playground:
These are the arguments for the http request posted above. You can use the Live Chart Playground to set up parameters like below.
chtt=Karakterfordeling
cht=bvg
chof=png
chs=300x300
chxt=x,y
chco=0076A3
chf=bg,s,65432100
hxr=0,0,50
chxl=0:
2
4
7
10
12
chxr=1,0,20
chbh=40,0,10
chd=t:2,60,70,10,90
In code you set the http string as your ImageSource. You can manipulate the http string in your code and adapt the chart parameters/data if needed. I would recommend using a Converter that you bind to from you XAML. Pass your data to the converter and let it return a ImageSource with the http request. If you are new to Converters you can probably find a few posts about it here on stackoverflow.
Don't use DLLs grab the files into your project.
Add WinRTXamlToolkit.Controls.DataVisualization.csproj to your solution and reference it in the main project and add this to your page.
xmlns:charting="using:WinRTXamlToolkit.Controls.DataVisualization.Charting"
xmlns:datavis="using:WinRTXamlToolkit.Controls.DataVisualization"
Look at the samples project http://winrtxamltoolkit.codeplex.com
Unfortunately, winrtxamltoolkit is only for WinRT; VS 2013 doesn't allow adding of project references of that kind to WinPhone projects.
WindowsPhone 8 （A jump to another application
）
I want to in my applications to invoke other applications, the application I don't know any news, just know the name, how do I use
. Await the Windows System. The Launcher. LaunchUriAsync (new Uri (" wechat: "));
"Wechat" should be placed here called program I want to use
First you have to write the following protocol in the WMAppManifest.xml under the Extensions tag. Thereafter you can launch your app from any other apps with the specified protocol name using Launcher.LaunchUriAsync method.
<Protocol Name="webchat" NavUriFragment="LaunchUri=%s" TaskID="_Default"/>
