When I call await PhotoCaptureDevice.OpenAsync(..) in windows phone 8 camera app throws InvalidOperationException.
System.InvalidOperationException: Operation is not valid due to the
current state of the object. at
System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task
task) at
System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task
task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at
JPMC.Controls.CaptureTaskLauncher.d_6.MoveNext() --- End of stack
trace from previous location where exception was thrown --- at
System.Runtime.CompilerServices.AsyncMethodBuilderCore.b_0(Object
state)}
but one more thing is whenever I run camera test first time it will work perfectly i.e PhotoCaptureDevice initialized properly but when I will come back from another page to Camera test it will give error mentioned above.
So,anyone can help me to figure out this problem ?
Thanks
Have you tried releasing the resources before leaving the page, using PhotoCaptureDevice.Close() and Dispose() ?
private static PhotoCaptureDevice d = null;
public static async Task<bool> InitializeCamera(CameraSensorLocation sensorLocation)
{
bool catchValue = true;
try
{
Windows.Foundation.Size initialResolution = new Windows.Foundation.Size(640, 480);
Windows.Foundation.Size previewResolution = new Windows.Foundation.Size(640, 480);
Windows.Foundation.Size captureResolution = new Windows.Foundation.Size(640, 480);
d = await PhotoCaptureDevice.OpenAsync(sensorLocation, initialResolution);
await d.SetPreviewResolutionAsync(previewResolution);
await d.SetCaptureResolutionAsync(captureResolution);

I want to retrieve some data from mysql in php and store it in array and then in Android I want to use that data. For example I want to retrieve the location of multiple people whose profession id = 1 (let's say) and then in Android I want to show that locations on map. I don't know how to do this. I have the following PHP and Android files which don't work. Please help.

Dear imdad: The Problem lies in you json file.
{"[]":{"user_id":"77","crtloc_lat":"34.769638","crtloc_lng":"72.361145"}, {"user_id":"76","crtloc_lat":"34.769604","crtloc_lng":"72.361092"},{"user_id":"87","crtloc_lat":"33.697117","crtloc_lng":"72.976631"}}
The Object is empty give it some name like here is response. Change it as:
{"response":[{"user_id":"77","crtloc_lat":"34.769638","crtloc_lng":"72.361145"},{"user_id":"76","crtloc_lat":"34.769604","crtloc_lng":"72.361092"},{"user_id":"87","crtloc_lat":"33.697117","crtloc_lng":"72.976631"}]}
Im working with windows phone 8.1 geolocation. The problem that I currently have is that my code only shows the first numbers of my coordinate. Example: If the coordinate is "41.233" the app only shows "41.00" . I need it to be as accurate as possible. In case it matters, im using windows phone 8.1 emulator to try the app, not an actual phone.
My code:
public sealed partial class MainPage : Page

bool shouldSend = false;
DispatcherTimer timer = new DispatcherTimer();
public MainPage()
{
this.InitializeComponent();
this.NavigationCacheMode = NavigationCacheMode.Required;

Thanks for your help!
Did you try out the Geolocator.DesiredAccuracyInMeters property?
geolocator.DesiredAccuracyInMeters = 3;
Reference & Sample
In this point LatitudeTxt.Text = geoposition.Coordinate.Latitude.ToString("0.00");
LongitudeTxt.Text = geoposition.Coordinate.Longitude.ToString("0.00");
You indicated that you have 0.00 decimals, for more accuracy you should put 0.000000
I have a list wich is loaded with elements each time the user make a research...These elements contain an Icon which is dowloaded with an async method GetByteArrayAsync of the HttpClient object. I have an issue when the user make a second research while the icon of the first list are still downloading.Because the list of elements is changing while Icon downloads are processing on each element of the first list. So my guess is that I need to cancel these requests each time the user proceed to a new research...Ive readen some stuuf on Task.run and CancellationTokenSource but I can't find really helpful example for my case so here is my code...Hope you can help me with that ...Thank you
public static async Task<byte[]> DownloadElementFile(BdeskElement bdeskElement)
{
//create and send the request
DataRequest requesteur = new DataRequest();
byte[] encryptedByte = await requesteur.GetBytesAsync(dataRequestParam);
return encryptedByte;
}
public async Task<Byte[]> GetBytesAsync(DataRequestParam datarequesparam)
{
var handler = new HttpClientHandler { Credentials = new NetworkCredential(datarequesparam.AuthentificationLogin, datarequesparam.AuthentificationPassword, "bt0d0000") };
HttpClient httpClient = new HttpClient(handler);
try
{
byte[] BytesReceived = await httpClient.GetByteArrayAsync(datarequesparam.TargetUri);
if (BytesReceived.Length > 0)
{
return BytesReceived;
}
else
{
return null;
}
}
catch (WebException)
{
throw new MyException(MyExceptionsMessages.Webexception);
}
}
EDIT
public async Task<Byte[]> GetBytesAsync(DataRequestParam datarequesparam)
{
var handler = new HttpClientHandler { Credentials = new NetworkCredential(datarequesparam.AuthentificationLogin, datarequesparam.AuthentificationPassword, "bt0d0000") };
HttpClient httpClient = new HttpClient(handler);
try
{
cts = new CancellationTokenSource();
HttpResponseMessage reponse = await httpClient.GetAsync(datarequesparam.TargetUri,cts.Token);
if (reponse.StatusCode == HttpStatusCode.OK)
{
byte[] BytesReceived = reponse.Content.ReadAsByteArrayAsync().Result;
if (BytesReceived.Length > 0)
{
return BytesReceived;
}
else
{
return null;
}
}
else
{
return null;
}
}
catch (WebException)
{
throw new MyException(MyExceptionsMessages.Webexception);
}
catch(OperationCanceledException)
{
throw new OperationCanceledException();
}
EDIT2
I need to cancel this funntion when the user make a new research and the list "listBoxGetDocsLibs" changed.
private async void LoadIconDocLibs()
{
foreach (var doclib in listBoxGetDocsLibs)//ERROR HERE COLLECTION HAS CHANGED
{
doclib.Icon = new BitmapImage();
try
{
byte[] Icon = await ServerFunctions.GetDocLibsIcon(doclib);
if (Icon != null)
{
{
var ms = new MemoryStream(Icon);
BitmapImage photo = new BitmapImage();
photo.DecodePixelHeight = 64;
photo.DecodePixelWidth = 92;
photo.SetSource(ms);
doclib.Icon = photo;
}
}
}
catch(OperationCanceledException)
{
}
}
}
First you need to define CancellationTokenSource:
private System.Threading.CancellationTokenSource cts;
place above code somewhere, where you can access it with your Button or other method.
Unfortunately GetByteArrayAsync lacks Cancelling - so it cannot be used with cts.Token, but maybe you can accomplish your task using GetAsync - which supports Cancelling:
ctsDownload = new System.Threading.CancellationTokenSource();
HttpResponseMessage response = await httpClient.GetAsync(requestUri, cts.Token);
Then you can get your content from response.
And when you want to Cancel your Task it can look like this:
private void cancelBtn_Click(object sender, RoutedEventArgs e)
{
if (this.cts != null)
this.cts.Cancel();
}
When you Cancel task an Exception will be thrown.
If you want to cancel your own async Task, a good example you can find at Stephen Cleary blog.
EDIT - you can also build your own method (for example with HttpWebRequest) which will support Cancelling:
For this purpose you will have to extend HttpWebRequest (under WP it lacks GetResponseAsync):
// create a static class in your namespace
public static class Extensions
{
public static Task<HttpWebResponse> GetResponseAsync(this HttpWebRequest webRequest)
{
TaskCompletionSource<HttpWebResponse> taskComplete = new TaskCompletionSource<HttpWebResponse>();
webRequest.BeginGetResponse(
asyncResponse =>
{
try
{
HttpWebRequest responseRequest = (HttpWebRequest)asyncResponse.AsyncState;
HttpWebResponse someResponse = (HttpWebResponse)responseRequest.EndGetResponse(asyncResponse);
taskComplete.TrySetResult(someResponse);
}
catch (WebException webExc)
{
HttpWebResponse failedResponse = (HttpWebResponse)webExc.Response;
taskComplete.TrySetResult(failedResponse);
}
catch (Exception exc) { taskComplete.SetException(exc); }
}, webRequest);
return taskComplete.Task;
}
}
Then your method can look like this:
public async Task<Byte[]> GetBytesAsync(DataRequestParam datarequesparam, CancellationToken ct)
{
HttpWebRequest request = HttpWebRequest.CreateHttp(datarequesparam.TargetUri);
request.Method = "GET";
request.Credentials = new NetworkCredential(datarequesparam.AuthentificationLogin, datarequesparam.AuthentificationPassword, "bt0d0000");
request.AllowReadStreamBuffering = false;
try
{
if (request != null)
{
using (HttpWebResponse response = await request.GetResponseAsync())
using (Stream mystr = response.GetResponseStream())
using (MemoryStream output = new MemoryStream())
{
const int BUFFER_SIZE = 10 * 1024;
byte[] buf = new byte[BUFFER_SIZE];
int bytesread = 0;
while ((bytesread = await mystr.ReadAsync(buf, 0, BUFFER_SIZE)) > 0)
{
output.Write(buf, 0, bytesread);
ct.ThrowIfCancellationRequested();
}
return output.ToArray();
}
}
else return null;
}
catch (WebException)
{
throw new MyException(MyExceptionsMessages.Webexception);
}
}
You can freely change Buffer Size which will affect how often Cancellation will be checked.
I haven't tried this but I think it should work.
I am trying to send a http web request from a background agent. The code is as below. The json_Callback never gets triggered and my request doesn't reach the server. I have done all the exception handling and none of them get triggered.

Not sure if this will help you or not, but here's how I make HTTP requests in my background agent:
Making the call using WebClient (this was written before the very nice HttpClient NuGet package became available):
public async Task<string> GetArrivalsAsync( IEnumerable<int> locations )
{
var request = new WebClient();
var requestUri = GetArrivalsRequestUri( locations );
var response = await request.DownloadStringTask( requestUri );
return response;
}
Note that I use the async/await keywords here which greatly simplifies writing asynchronous code. Most of the work is done in this extension method to WebClient. I can't take credit for the extension method, but it's been a while and I can't recall where I found it (although it was probably here on StackOverflow):
/// <summary>
/// The WebClientExtensions class provides extension methods for the <see cref="System.Net.WebClient"/> class.
/// </summary>
public static class WebClientExtensions
{
/// <summary>
/// This extension method is used to asynchronously download data from a URI
/// and return that data in the form of a string.
/// </summary>
/// <param name="webClient">The <see cref="System.Net.WebClient"/> instance used to perform the download.</param>
/// <param name="uri">The URI to download data from.</param>
/// <returns>The <see cref="Task"/> used to perform the operation.</returns>
public static Task<string> DownloadStringTask( this System.Net.WebClient webClient, Uri uri )
{
if ( uri == null )
{
throw new ArgumentNullException( "uri" );
}
var tcs = new TaskCompletionSource<string>();
webClient.DownloadStringCompleted += ( s, e ) =>
{
if ( e.Error != null )
{
tcs.SetException( e.Error );
}
else
{
tcs.SetResult( e.Result );
}
};
webClient.DownloadStringAsync( uri );
return tcs.Task;
}
}
The following WithDefaultCredentials() works but WithCredentialsMe() fails with a http 401 returned ?
The difference is that
ICredentials credentials = System.Net.CredentialCache.DefaultCredentials;
works OK against the report server 2008 url , but
ICredentials credentials = new NetworkCredential("myUsername", "myPassword", "ourDomain");
comes back with a HTTP 401.
The console app is being developed by me so, there should not be a difference between DefaultCredentials and NetworkCredential. There is no problem with my Username and password.
Any ideas ?
