What is "sticky notes"?
Ans: Sticky note is a simple note keeping application of Windows. It remains on the top of the every window. We can use it to write down small notes that requires frequent attention.

Concept of serialization:
To save the current state of sticky note we can use Serialization concept. Serialization is the process of converting an object into a stream of bytes in order to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.

Steps to create this utility:
Create a Windows Form based project in IDE.
Add TextBox control on the Windows form
Set following properties of the TextBox control:
Dock Style to Fill
Multiline to True
Code Snippnets:
//storing notes in My Documents of windows

FileStream mynotes = new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\mynotes.nfc", FileMode.Create);

BinaryFormatter format = new BinaryFormatter();
format.Serialize(mynotes, txtUser.Text);
mynotes.Close();



//opening notes on application launch
if (File.Exists(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\mynotes.nfc"))
{
FileStream opennotes = new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\mynotes.nfc", FileMode.Open);
BinaryFormatter format = new BinaryFormatter();
txtUser.Text = (string)format.Deserialize(opennotes);
opennotes.Close();
}
