I'm trying to select all the work's accidents between two dates, but my datatype in sql server 2000 is varchar instead datetime.

Can I select multiple dates for the month?

Me.Width is what i am having issues with. I can adjust the width to work on my system but the bar is a different amount of pixels on different versions of windows. I was wondering if there was a function that would give u the amount of pixels the side bar is. I was considering writing some code so look for a color change but people can change the color so i do not think it would work very well. Also the program allows you to draw in a picture box so that would make it hard to get it to work correctly.
