Help in using the TrackBar

It's just a matter of splitting the TrackBar's range up amongst how many cases you've got. For example, with 4 cases:

int range = trackBar1.Maximum - trackBar2.Minimum;
int distance = trackBar1.Value - trackBar1.Minimum;

if (trackBar1.Value <= range/4)
{
{
    label1.Text = "Stock";
}
else if (distance > range/4 && distance <= range/2)
{
    label1.Text = "Shares";
}
else if (distance > range/2 && distance <= range * 3/4)
{
    label1.Text = "Cash";
}
else
{
    label1.Text = "Property";
}    

Something like this perhaps:

if (trackBar1.Value <= (trackBar1.Minimum + trackBar1.Maximum)/2)
{
    label1.Text = "Stock";
}
else
{
    label1.Text = "Shares";
}
