Ok, this doesn't seem like it should be that difficult, but I be darned if I can figure it out. I am trying to make my own "Slider.OCX". I have an imagebox inside a picturebox and it scrolls up and down likeit should with working ticks and all that other crap. My problem is coming up with the formula to figure out the current value for the slider. It has "Min" & "Max" values that need to be taken into consideration also. So I'm guessing you subtract the "min" from the "max" to get the available range and use that to calculate where the imagebox is inside the picturebox.....(somehow). I'm giving 100 points because this has p!ssed me off so much. OK math guru's, what do you say?
