It's real simple to use the built-in Settings functionality.

To add a setting, just right click on your forms project in the solution explorer and choose, "Properties".

On the left, click on the Settings tab.

Enter a new setting (I called mine 'MySavedFolder'). Choose the type and visibility (User or application). I chose User. Give the setting a default value (I used 'default value').

Next, wire up the setting in the forms code. I created a simple test form with an textbox and a save button. In the form editor, double click on the button to create a button handler.

Next, wire up the setting.

public partial class Form1 : Form { public Form1() { InitializeComponent(); // Retrieve the settings and load it into the textbox textBox1.Text = Properties.Settings.Default.MySavedFolder; } private void saveButton_Click(object sender, EventArgs e) { // Save the value from the textbox into the settings. Properties.Settings.Default.MySavedFolder = textBox1.Text; Properties.Settings.Default.Save(); } }

The second useful technique is that the program saves the user’s selection between runs. At design time I created a setting named Directory. To create a setting, double-click the Properties entry in Solution Explorer and go to the Settings tab.

When it starts, the program uses the following code to load the value saved in this setting.

// Restore the saved directory. private void Form1_Load(object sender, EventArgs e) { txtDirectory.Text = Properties.Settings.Default.Directory; }

The program uses the following code to save the current selection when the form closes.

// Save the current directory. private void Form1_FormClosing(object sender, FormClosingEventArgs e) { Properties.Settings.Default.Directory = txtDirectory.Text; Properties.Settings.Default.Save(); }
