It gets a bit annoying after a while, so he asked me if I could rotate it 180 degrees before attaching it to the email. I have absolutely no idea - hence my post. The app is on a hosted ASP.Net v3.5 web server.

View 2 RepliesIn a game i am making, as the mouse cursor i have crosshairs (like those in FPS games) and i would like an image box to change images as the mouse moves so that it appears that the character in the picturebox is following the mouse cursor.
i thought i would do something along the lines of first finding out which side of the picture box its on (left or right) then finding out exactly where with some maths equations and then assigning 1 of 60 pictures so that it appears that the picture is rotating.
