Calm down.

If your problem really is that urgent, then I suggest you get out your
cheque book and contact an IDL consultant (like David Fanning, but there
are others) and offer him/her a large amount of money to get his/her
attention.

Failing that, you must accept that people who follow this newsgroup can
be very helpful, for free, but *in their own time* and they prefer to
see evidence that the person they are helping has made some effort to
help him/herself.

Now, please take the time to explain carefully what you are trying to
do, what you have done so far, what problems you have encountered and
exactly what you want help with.

What does "I have the ROI with me" mean? Have you read the IDL
documentation for the IDLanROI class? Do you understand how to create an
IDLanROI object given a list of vertices? And then to use the
ComputeGeometry method to calculate various geometric parameters,
including area? Do you want some example code that uses this?
