Question

I don’t know why I’m facing that error !
Here is my code snippet :

public void SaveImageTo(string fileName="ABC.jpg") 
    {
        var myStore = IsolatedStorageFile.GetUserStoreForApplication();
        if (myStore.FileExists(fileName))
        {
            myStore.DeleteFile(fileName);
        }

        IsolatedStorageFileStream myFileStream = myStore.CreateFile(fileName);
        qrImage.SaveJpeg(myFileStream, qrImage.PixelWidth, qrImage.PixelHeight, 0, 85);
        myFileStream.Close();

        // Create a new stream from isolated storage, and save the JPEG file to the media library on Windows Phone.
        myFileStream = myStore.OpenFile(fileName, FileMode.Open, FileAccess.Read);
        MediaLibrary library = new MediaLibrary();
        //byte[] buffer = ToByteArray(qrImage);
        library.SavePicture(fileName, myFileStream);
    }

It gives me “Operation not permitted on IsolatedStorageFileStream”, Here qrImage is a global writablebitmap. need help !
Thanks in advance !
