Thanks, I never thought of the task scheduler, Once I get the weather station set up I will try it.
The machine I want to run the software on is a pentium 4 so it is single core.
When the programme takes a recording is this recording include the date and time it was taken, so I know when it was recorded?.
I plan on taking readings twice a day 9 am and 3 pm and then put the data into an excel file.
