So i have a small xamarin project. Just a little stopwatch:
public partial class Stopwatch : ContentPage
{
Stopwatch stopwatch;
public Stopwatch()
{
InitializeComponent();
stopwatch = new Stopwatch();
labeltimer.Text = "00:00:00.00";
}
private void btnTimerReset(object sender, EventArgs e)
{
btnStart.Text = "Start";
stopwatch.Reset();
}
private void btnTimerstop(object sender, EventArgs e)
{
if (labeltimer.Text != "00:00:00.00")
btnStart.Text = "Resume";
stopwatch.Stop();
}
private void btnTimerStart(object sender, EventArgs e)
{
Timerstart();
}
private void Timerstart()
{
stopwatch.Start();
Device.StartTimer(TimeSpan.FromMilliseconds(1), () =>
{
labeltimer.Text = stopwatch.Elapsed.ToString("hh\\:mm\\:ss\\.ff");
return true; // return true to repeat counting, false to stop timer
});
}
}
}
My problem is now, that everything works perfectly, until i start the stopwatch and lock my phone. The stopwatch then works very slow.
Any idea, how to fix that?

Use the TCPClient instance returned by the AcceptTCPClient() method.
TCPClient _client = _listener.AcceptTCPClient();
// Add to listview here for connection
Console.WriteLine(String.Format("{0} connected", _client.Client.RemoteEndPoint.ToString()));
// Same for others
UPDATE
TCPClient _client = _listener.AcceptTCPClient();
ListViewItem _item = new ListViewItem(_client.Client.RemoteEndPoint.ToString());
listview1.Items.Add(_item);

i need to take a picture from the directory of Windows phone in my application so i add a child Windows when i click on the text in this child Windows i add a button and i called
public partial class AnnotationControl : ChildWindow
{
public ObservableCollection<string> cercle { get; set; }
public AnnotationControl()
{
InitializeComponent();
}

{
PhotoChooserTask objPhotoChooser = new PhotoChooserTask();
objPhotoChooser.Completed += new EventHandler<PhotoResult>(PhotoChooseCall);
objPhotoChooser.Show();
}
but when i clicked on the button to choose a picture the application crashed
"Application_UnhandledException"
some one have any idea please
Use this may be helpful
private void changeImage(object sender, RoutedEventArgs e)
{
PhotoChooserTask photoChooserTask = new PhotoChooserTask();
photoChooserTask.Completed += new EventHandler<PhotoResult>(photoChooserTask_Completed);
photoChooserTask.Show();

if (e.TaskResult == TaskResult.OK)
{
System.Windows.Media.Imaging.BitmapImage bmp = new System.Windows.Media.Imaging.BitmapImage();
bmp.SetSource(e.ChosenPhoto);
imageTapped.Source = bmp;
}

How to get the slideshow of images with time interval of 2 seconds. I had referred the below code from stackoverflow but while running iam nt getting any images displayed.. Please tel where iam went wrong...
Xaml:
<image Name=myImg Source={Binding bi}/>
Code:
private DispatcherTimer tmr = new DispatcherTimer();
private List<string> images = new List<string>();
private int imageIndex = 0;
public MainPage()
{
InitializeComponent();
Loaded += new RoutedEventHandler(MainPage_Loaded);
}
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
tmr.Interval = TimeSpan.FromSeconds(5);
tmr.Tick += new EventHandler(tmr_Tick);
LoadImages();
ShowNextImage();
}
private void LoadImages()
{
// list the files (includede in the XAP file) here
images.Add("/images/filename1.jpg");
images.Add("/images/filename2.jpg");
images.Add("/images/filename3.jpg");
images.Add("/images/filename4.jpg");
}
private void ShowNextImage()
{
Imagesource bi = new BitmapImage(new Uri(images[imageIndex], UriKind.Relative));
myImg.Source = bi;
imageIndex = (imageIndex + 1) % images.Count;
}
void tmr_Tick(object sender, EventArgs e)
{
ShowNextImage();
}
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
if (!tmr.IsEnabled)
{
tmr.Start();
}
base.OnNavigatedTo(e);
}
protected override void OnNavigatedFrom(System.Windows.Navigation.NavigationEventArgs e)
{
tmr.Stop();
base.OnNavigatedFrom(e);
}
Thanks in Advance
Change Name=myImg to x:Name="myImg" and remove the Source attribute entirely. Otherwise it looks like it should work.
I work in Microsoft Visual Studio 2010, Windows phone.
Can someone help me with audio recorder. When I play it I can heard it twice but not always. After that can someone tell me how to save it to isolated storage and play it from there.
Thanks.

I have tried numerous attempts to fix this problem or bug, firstly by deleting the .tbd files from C:\Users\\AppData\Local\Microsoft\VisualStudio\x.0
I have also tried this:
Visual Studio "Tools" menu
"Options" submenu
"Windows Form Designer" tab
"General" tab
Set "AutoToolboxPopulate" to "True"
The ToolBox list is still not populating correctly and the "BackgroundWorker" component I need is grayed out. Any ideas?
At least a workaround: declare the BackgroundWorker in code, but don't forget to dispose it properly:
public class MyForm : Form
{
private BackgroundWorker bgWorker = null;
public MyForm()
{
InitializeComponent();
this.bgWorker = new BackgroundWorker; //TODO: set properties and event handlers
}
public override void Dispose(bool disposing)
{
//TODO: copy from MyForm.Designer.cs and add:
Backgroundworker bgw = this.bgWorker;
this.bgWorker = null;
if (disposing && bgw != null)
{
try
{
//TODO: release event handlers
bgw.Dispose();
}
catch(Exception)
{
/* consumed disposal error */
}
}
}
}
I have found a solution to my problem, using the BackgroundWorker class in C# without using the component from the toolbox. In this case, I needed two seperate backgroundWorkers:
using System.Threading;
public partial class MainWindow : Window
{
private BackgroundWorker bw1 = new BackgroundWorker();
private BackgroundWorker bw2 = new BackgroundWorker();
public MainWindow()
{
InitializeComponent();
bw1.WorkerReportsProgress = true;
bw1.DoWork += new DoWorkEventHandler(bw1_DoWork);
bw1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw1_RunWorkerCompleted);
bw1.ProgressChanged += new ProgressChangedEventHandler(bw1_ProgressChanged);
bw2.WorkerReportsProgress = true;
bw2.DoWork += new DoWorkEventHandler(bw2_DoWork2);
bw2.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw2_RunWorkerCompleted);
bw2.ProgressChanged += new ProgressChangedEventHandler(bw1_ProgressChanged);
}
private void bw1_DoWork(object sender, DoWorkEventArgs e)
{
StatsProcessor proc = new StatsProcessor();
proc.CompareStats(listText1, listText2);
}
private void bw2_DoWork2(object sender, DoWorkEventArgs e)
{
StatsParser parser = new StatsParser();
}
private void bw1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
progressBar2.IsIndeterminate = false;
progressBar2.Value = 100;
btnCompareStats.IsEnabled = true;
}
private void bw2_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
progressBar1.IsIndeterminate = false;
progressBar1.Value = 100;
btnFetchStats.IsEnabled = true;
}
private void bw1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.progressBar2.Value = e.ProgressPercentage;
}
private void bw2_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.progressBar1.Value = e.ProgressPercentage;
}
private void btnCompare_Click(object sender, EventArgs e)
{
btnCompareStats.IsEnabled = false;
StatsProcessor proc = new StatsProcessor();
if (bw1.IsBusy != true)
{
progressBar2.IsIndeterminate = true;
// Start the asynchronous operation.
bw1.RunWorkerAsync();
}
}
private void btnFetchStats_Click(object sender, RoutedEventArgs e)
{
btnFetchStats.IsEnabled = false;
if (bw2.IsBusy != true)
{
progressBar1.IsIndeterminate = true;
// Start the asynchronous operation.
bw2.RunWorkerAsync();
}
}
}
I would try resetting the toolbox items. Then use the Add Item dialog to put back something you need.
