I don"t know of a library, but you can use an algorithm to calculate
the area. I think it"s called Bragg"s algorithm. Maybe not.

workaround. If you include the PATH to the folder containing the
shortcut as a parameter in yo...

::2012-01-23 ::Calculate area of an enclosed irregular shape

Hi,
I have a series of approx. 40 points (x,y) that make up an irregular

Is there a simple library / function that I can call that will
calculate the enclosed area of this shape?
TIA.

keys). Upon starting, I need program to determine the folder name of
the link that started it. Is there a way to do this?
