Hi,

you could do it this way:

C#

int nTrackBarPosition = 0;
public Form1()
{
  InitializeComponent();
  nTrackBarPosition = trackBar1.Value;
}

private void trackBar1_Scroll(object sender, EventArgs e)
{
  if (nTrackBarPosition < trackBar1.Value)
    Console.WriteLine("MoveRight");
  else
    Console.WriteLine("MoveLeft");
  nTrackBarPosition = trackBar1.Value;
}

I stilll cant get it to work..

if (nTrackBarPosition > trackBar1.Value)
{

for (int i = 0; i < 11; i++)
{
Px[i] = Px[i] - px;
}
}
else if(nTrackBarPosition < trackBar1.Value)
{

for (int i = 0; i < 11; i++)
{
Px[i] = Px[i] + px;
}
}

It still only does 1 thing no matter in wich way i move the trackbar...

Have you tried setting breakpoints inside the if blocks to see if they are getting called? Please also don't forget to use the line: "nTrackBarPosition = trackBar1.Value;"
