Chia sẻ file, dữ liệu giữa các máy tính trong mạng LAN, Công ty, văn phòng, trường học, gia đình

HƯỚNG DẪN CHIA SẺ TÀI LIỆU GIỮA CÁC MÁY TÍNH TRONG MẠNG LAN

Bước 1: Vào Netword and Sharing Center bằng cách vào Control panel tìm và chọn Netword and Sharing Center

Bước 2: Vào Change advanced sharing settings.

Bước 3: Tiếp theo, bạn nhấn vào Private

Bước 4: Tích vào các tùy chọn như dưới và nhấn Save changes để lưu thiết lập

Bước 5: Vào thư mục, file bạn muốn chia sẻ phải chuột và chọn properties

Bước 6: Chuyển qua tab Sharing và chọn Share...

Bước 7: Nhấn chọn Everyone sau đó nhấn Add, tiếp theo nhấn Share để chia sẻ Files, thư mục

Bước 8: Từ máy muốn copy dữ liệu bạn gõ vào địa chỉ tên máy hoặc địa chỉ IP của máy đã chia sẻ dữ liệu bằng cách nhấn tổ hợp Windows +R sau đó gõ vào theo cú pháp:

\\Computer_Name

Hoặc \\ip_address

Trong đó Computer_Name là máy chia sẻ dữ liệu, ip_address là địa chỉ IP của máy chia sẻ dữ liệu

Ví dụ: Máy Taimienphi1 muốn truy cập vào máy Taimienphi2 để copy dữ liệu bạn có thể gõ \\Taimienphi2

http://thuthuat.taimienphi.vn/chia-se-tai-lieu-giua-cac-may-tinh-trong-mang-lan-2066n.aspx 
Trên đây chúng tôi vừa hướng dẫn bạn cách chia sẻ dữ liệu giữa các máy tính trong mạng Lan. Với thủ thuật này, bạn có thể nhanh chóng và dễ dàng copy, chuyển đổi dữ liệu giữa máy tính trong mạng Lan mà không cần phải có các thiết bị khác.

Windows Store và JSON: Tạo file Json vs Browser Images và Search Name từ Json hiển thị - Windows Store Apps

Test WADS2

--Tạo JSON--
//Contact c = new Contact();
//c.name="Antonio"
string json = Newtonsoft.Json.JsonConvert.SerializeObject(c);

StorageFolder localFolder = ApplicationData.Current.LocalFolder;

StorageFile textFile = await localFolder.CreateFileAsync("contact3.json",CreationCollisionOption.ReplaceExisting);
using (IRandomAccessStream textStream = await textFile.OpenAsync(FileAccessMode.ReadWrite))
{
          using (DataWriter textWriter = new DataWriter(textStream))
          {
                textWriter.WriteString(json);
                await textWriter.StoreAsync();
          }
}

--Đọc JSON--
StorageFolder localFolder = ApplicationData.Current.LocalFolder;
StorageFile textFile = await localFolder.GetFileAsync("contact3.json");
using (IRandomAccessStream textStream = await textFile.OpenReadAsync())
{
      DataReader textReader = new DataReader(textStream);
      uint textLength = (uint)textStream.Size;
      await textReader.LoadAsync(textLength);
      string jsonContent = textReader.ReadString(textLength);

      JsonValue jsonValue = JsonValue.Parse(jsonContent);

      string name = jsonValue.GetObject().GetNamedString("name");
      tbName.Text = name; //VD: đưa value name vào textBox
}

--Hiển thị Value trên ComboBox--
protected override void OnNavigatedTo(NavigationEventArgs e)
{
        List<string> item = new List<string>();
        item.Add("family");
        item.Add("family_2");
        item.Add("family_3");
        comboBox.DataContext = item;
}

<ComboBox x:Name="comboBox" ItemsSource="{Binding}" />

--Display ảnh từ Pictures Library--
var file = await
Windows.Storage.KnownFolders.PicturesLibrary.GetFileAsync("human.png");
var stream = await file.OpenReadAsync();
var bitmapImage = new BitmapImage();
bitmapImage.SetSource(stream);

this.image.Source = bitmapImage;
