Create a simple program time data logging using CVI-Track the usage of the program

-Objective: Is to record this CVI program time during the start and the end of this program information are record into a doc file (must be run in background) and retrieve the data when needed.

Addition: Add total time and record into a doc file also.    

I think information needed are CVI timer, CVI write to file , CVI read from file…etc ? any think I miss out?

-Is there any example or advice related to the above to share with me to ease my writing?

Thanks
