This is basically one way of going about it. It might need a little tweak near the ends of the trackbar, but you get the idea... try increasing the maximum ticks for better resolution.
private void trackBar1_MouseDown(object
{
int numberTicks = (trackBar1.Maximum - trackBar1.Minimum)/(trackB
float percent = ((float)e.X )/(float)trackBar1.Size.Wi
int newValue = (int) ((float) numberTicks * (float)percent);
trackBar1.Value = newValue;
}
cheers,

i should also mention that the tweak at the ends i mentioned is due to the fact that the actual trackbar doesn't stretch from end-to-end of the trackbar size. you'll notice that the trackbar has about 10 pixels of padding on each end. it shouldn't be too hard to compensate by adding that to the above equation.
let me know if you have any questions.
good luck,

I have looked at the trackbar and considered the tweak that you mentioned. It looks as though the further you move from the center the more off the values are. It is not just the ends. The only way I can think of correcting this problem is doing some heavy calculations based on one half of the trackbar, the 10 pixels on the end, and the position of the pointer. I am thinking along the lines of having to take half of the trackbar width, divide it by 10, and based on which section of 10 the pointer is located, adding the correct number(1-10) to the variable holding the pointers x position. Does that sound right or am I making it harder than it is??????
Thanks,

That would probably work but I think that is making it a bit more complicated than necessary. I don't know the exact amount of pixels at each end because I think it is proportional to the length of the toolbar. However, you can modify the percentage calculation as such to get a closer approximation:
float percent = ((float)e.X - 10)/(float)(trackBar1.Size
this way you're decreasing the total width by 2x and offsetting the mouse cursor by 1x. that should do the trick.

Excellent. I hate that you had to give me the calculations, but I never would have thought of that formula.
