Capturing Mouse Movement
Many of you have probably seen "mouse meters" that track how many pixels the mouse has moved. I'm trying to do that but I can't figure out how to execute code every time there's a mousemove (on any control, let alone the entire screen). This is what I've gotten so far but it doesn't work. Any ideas
Capturing Mouse Movement

namespace mmove
{
public partial class Form1 : Form
{
int pxls = 0;
int lx = 0;
int ly = 0;
bool started = false;
public Form1()
{
InitializeComponent();
}
protected override void OnMouseMove(MouseEventArgs e)
{
if (started == false)
{
lx = e.X;
ly = e.Y;
started = true;
}
if (e.Y - ly == 0)
pxls = pxls + (int)Math.Abs(e.X - lx);
else if (e.X - lx == 0)
pxls = pxls + (int)Math.Abs(e.Y - ly);
else
{
int slope = (int)Math.Abs((e.Y - ly) / (e.X - lx));
if (slope >= 1)
pxls = pxls + (int)Math.Abs(e.Y - ly);
else if (slope < 1)
pxls = pxls + (int)Math.Abs(e.X - lx);
}
lx = e.X;
ly = e.Y;
}
private void Form1_Load(object sender, EventArgs e)
{
this.Capture = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
textBox1.Text = pxls.ToString();
}
}
}

You could try using the mouse_event API...

Try calling
this.Capture = true;
on your form's OnLoad override.

I rewrote it slightly and I got a working program but it only counts while the mouse is in the application window. I have this.capture set as i was told... here's my complete code
namespace mmove
{
public partial class Form1 : Form
{
int pxls = 0;
public Form1()
{
InitializeComponent();
}
protected override void OnMouseMove(MouseEventArgs e)
{
pxls++;
textBox1.Text = pxls.ToString();
}
private void Form1_Load(object sender, EventArgs e)
{
this.Capture = true;
}
}
}

You could try implementing DirectX's Direct Input. It handles mouse moves all over the screen... And also you could capture keyboards, joystick and other input devices...
