In my windows phone 7 application, i have created a button to change the default background image and the users can have their own custom skins on the app. It worked perfectly. But when the users exits the app and relaunches it again the application's background image is changed to default. But what i needed is, the application should have the last image that is chosen by the user even is launched no. of times. Can anyone help me with this? Thanks in advance for your hard work!
private void BackgroundBrowserIcon_MouseEnter(object sender, MouseEventArgs e)
{
var PhotoChooser = new PhotoChooserTask();
PhotoChooser.Completed += new EventHandler<PhotoResult>(PhotoChooser_Completed);
PhotoChooser.Show();
}
void PhotoChooser_Completed(object sender, PhotoResult e)
{
{
if (e.TaskResult == TaskResult.OK)
{
System.Windows.Media.Imaging.BitmapImage bmp = new System.Windows.Media.Imaging.BitmapImage();
bmp.SetSource(e.ChosenPhoto);
var app = Application.Current as App;
if (app == null)
return;
var imageBrush = new ImageBrush { ImageSource = bmp, Opacity = 1.0d };
this.LayoutRoot.Background = imageBrush;
app.backchanged = true;
app.appbrush = imageBrush;
}
}
}
Are you using IsolatedStorageSettings to store the last chosen photo, and then loading it on app launch?

I converted a window of mine to use CefSharp in order to render some PDF file. One of the features the old component supported (WebBrowser of WPF, which unfortunately depends on IE, which does not work in this case) is accessing javascript elements through code in order to be aware of when the PDF has been scrolled to the bottom. Unfortunately this does not appear to work with CefSharp with the following code. Perhaps i am missing some initializer flag for this to work?
Currently in my Logs All i get is ScrollProgress|0|0|734

On button2_click i want to update the file by using data from a textBox2, can anybody complete it?
I won't complete it, but I will point you in the right direction. You have to have a reference to Microsoft Word. What you are trying to do is typically referred to as automation or more specifically Microsoft Word Automation.
You can google that and find examples or try this location for starting point.

My problem above is solved, thank you :)
but I have another problem on integral projection, I didn't know how to do it though.
please help, thank you in advance
Some comments:
Your two private variables are very confusingly named. Your CaptureDevice is a collection of all the capture devices on the computer, while your FinalFrame is a capture device.
You do not look for canny edges on the bitmap upon reception.
The NewFrame event handler runs in the streaming thread, so you should use a .BeginInvoke in there to make it usable by the UI thread.
What you may do:
Inside _NewFrame handler, use BeginInvoke to transfer the cloned image to a ProcessCameraImage method (that will hence run on the UI thread).
Apply canny edge detection within this method.
Then assign the result to your picture box.
Note: I don't know how CPU heavy canny edge detection is. If it's costly, doing it on the UI thread may block user interaction. In that case you could do it within the streaming thread and only transfer the processed image for display. But depending on the time it takes, this may force the camera to lower its framerate.
thank you for your answer, it has been solved just now, I've modified it and it somehow solved

You can get all the user's videos and get the latest date:
var videos = new YouTubeRequest().GetVideoFeed(userId).Entries
DateTime lastUploadDate = videos.Max(video => video.YouTubeEntry.Published)
To get the actual video's title:
var lastVideo = videos.Where(video => video.YouTubeEntry.Published == lastUploadDate).First();
var name = lastVideo.Title
