Morgan Proffitt:

I have a small application which uses a small text document and searches through the lines for items. I am trying to get the program to grab an image from a page which would correspond to the search. I cannot get anything working to download the image. I have tried multiple solutions involving async and httpclient. But I really can't apply anything to work. I currently have this which MAY work, but I am a total noob to all this stuff, I enjoy creating little UI apps, I've never worked outside of the methods given.

public async static Task LoadImage(Uri uri)
    {
        BitmapImage bitmapImage = new BitmapImage();
        string url = "http://ift.tt/2DU1iFi";

        try
        {
            var rootFolder = await Windows.Storage.ApplicationData.Current.LocalFolder.CreateFolderAsync(@"Assets/images/", CreationCollisionOption.OpenIfExists);

            var coverpic_file = await rootFolder.CreateFileAsync("exotic", CreationCollisionOption.FailIfExists);
            try
            {
                System.Net.Http.HttpClient client = new System.Net.Http.HttpClient(); // Create HttpClient
                byte[] buffer = await client.GetByteArrayAsync(url); // Download file
                using (Stream stream = await coverpic_file.OpenStreamForWriteAsync())
                    stream.Write(buffer, 0, buffer.Length); // Save
            }
            catch
            {
            }
        }
        catch
        {
        }

        return null;
    }

How do I get this to run on the click of a button? Or even, a better solution. Cheers
