CameraCaptureTask on WP7

Question

I want to use CameraCaptureTask on WP7 to get the image from the phone and manipulate it. My code is:

CameraCaptureTask cameraCaptureTask; public MainPage() { InitializeComponent(); try { cameraCaptureTask = new CameraCaptureTask(); cameraCaptureTask.Completed += new EventHandler<PhotoResult>(cameraCaptureTask_Completed); } catch (System.InvalidOperationException ex) { MessageBox.Show(ex.Message); } } private void button1_Click(object sender, RoutedEventArgs e) { try { cameraCaptureTask.Show(); } catch (System.InvalidOperationException ex) { MessageBox.Show(ex.Message); } } void cameraCaptureTask_Completed(object sender, PhotoResult e) { MessageBox.Show("event: " + e.TaskResult.ToString()); if (e.TaskResult == TaskResult.OK) { BitmapImage bmp = new BitmapImage(); bmp.SetSource(e.ChosenPhoto); image1.Source = bmp; } } } 

The problem is that every time I press button1, the event is raised, but the value is TaskResult.Cancel instad OK. In addition, the camera does not display on the phone.

Any idea? Thanks

Do you work with a debugger application? If so, the camera will not work when you connect to the device using Zune software.

If you connect using the WPConnect tool, it should work.

You can try this ...

 private void button1_Click(object sender, RoutedEventArgs e) { try { cameraCaptureTask = new CameraCaptureTask(); cameraCaptureTask.Completed += new EventHandler<PhotoResult>(cameraCaptureTask_Completed); cameraCaptureTask.Show(); } catch (System.InvalidOperationException ex) { MessageBox.Show(ex.Message); } } void cameraCaptureTask_Completed(object sender, PhotoResult e) { MessageBox.Show("event: " + e.TaskResult.ToString()); if (e.TaskResult == TaskResult.OK) { BitmapImage bmp = new BitmapImage(); bmp.SetSource(e.ChosenPhoto); image1.Source = bmp; } }

Try it.

 void ctask_Completed(object sender, PhotoResult e) { if (e.TaskResult == TaskResult.OK && e.ChosenPhoto != null) { //Take JPEG stream and decode into a WriteableBitmap object App.CapturedImage = PictureDecoder.DecodeJpeg(e.ChosenPhoto); //Collapse visibility on the progress bar once writeable bitmap is visible. progressBar1.Visibility = Visibility.Collapsed; //Populate image control with WriteableBitmap object. ImageMain.Source = App.CapturedImage; } }
