I am converting an old program which measures zooplankton. It involves a camera connected to a microscope used to view the critters in lake water samples. I want to be able to measure them using the mouse sort of like this pseudo-code: On Mouse_Left_Button_Down - record starting position While Mouse_Move (and Mouse_Button_Down) draw a line from starting position to current position and erase the line from the last position. i.e. the visual effect is a line which is anchored to the starting point and stretches to the current mouse position On Mouse_Left_Button_Up - record end position. Calculate length of line and store in database. Any clues would be appreciated!
