Auto Updating Text Labels?

I'm currently trying to get show screen coordinates on my little thing I made.. but I am having issues refreshing the text to the new X, Y values.

int x = Cursor.Position.X;
int y = Cursor.Position.Y;

textBox1.Text = "X: " + x + " Y: " + y + "";
textBox1.Refresh();

That's what I have, but I don't understand why it isn't refreshing? If someone can explain it to me it would be great.

As Patrick Hofman has told you, you must handle the mouse move event. Try this code:

public Form1()
{
    InitializeComponent();
    this.MouseMove += new MouseEventHandler(Form1_MouseMove);
}

void Form1_MouseMove(object sender, MouseEventArgs e)
{
    int x = Cursor.Position.X;
    int y = Cursor.Position.Y;

    textBox1.Text = "X: " + x + " Y: " + y + "";
}

The text doesn't magically update itself.

You have to handle the appropriate event, for example MouseMove on your form.

So hook up the event in the constructor;

public Form1()
{
    InitializeComponent(); // this is usually already there

    this.MouseMove += Form1_MouseMove;
}

Then call your code inside the event handler:

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
    int x = Cursor.Position.X;
    int y = Cursor.Position.Y;

    textBox1.Text = "X: " + x + " Y: " + y + "";
}

Note that this might get slow when there are a lot of events raised. You can build some timer mechanism to update every once in a while, depending on your needs.
