I've read the status of the mouse button using the GetMessageA function
in user32.dll (its the 3rd argument). Unfortunately, I think labview
also calls this function to determine mouse events, so if you read this
function in a fast loop, Labview fails to react to mouse clicks in
regards to events on the fron panel. If you want to control something
cheaply using a button, maybe you could try a cheap game pad or 2-
button joystick and read the game port using the "in port.vi"
function. You could also rig up a button and h
ook it between a data
line and ground on the parallel port if it is not in use.
