Hey guys. I asked this once before and never really figured anything out. I thought I had gotten out of doing this, but my friend called me today looking for his program. So here it goes.

My friend is a chiropractor and he needs a program to time reflexes. What he wants is for the screen to change color, then the user hit spacebar as fast as he/she can and then record the time it took to do so. I need to record the time down to the thousandths (.999). The timer in VB only does the hundredths (.99) and I hear isn't the most accurate thing in the world. Is there a way to get it down to the thousandths? Someone gave me a link to another VB timer but it was very confusing and I did not get it to work at all. Any help would be great!!!!!! Thanks!

Here is the program:

User sits at screen.
Screen changes from blue screen to green screen...counter starts
User hits spacebar as soon as he/she sees the green screen
When spacebar hit, counter stops.
Output info.
