Hi,
I don't know what you are using to capture the GPS and A/D converter, but
many of the industry ship software control and many as OLE Objects.

Assuming some OLEObject were shipped, instead of looping in a vba loop and
request values every second, you could a object, say oGPS that you would set
to 1 second and the object would Tick every second. By capturing and
processing the event only, there would be no loop and the user could continue
to work or do whatever such as stopping the recording process.

If you don't have such software, you could create a timer that only run the
recording macro every second. See:

I have written a macro for a uni project.

It takes in values from a GPS (location) and A/D converter (signal
strangth).
It records these values once a second in a loop.

I want the user to be able to stop running this program whenever they
have
enough data.

Please Help Me!

Thankyou in advance...
