About File IO and Time Intervals

Dear All,

I want the solutions for the below problem.

I have one file "info.txt" which contains fix format as

TaskName=Iteration1

Counter=0

Status=Up

So i want to update the counter every 100ms upto 100 and reset to 0 after 100. the file contents should be same only counter will be updated. and also i want to take a log of this file into 'logfile.txt' after every 800ms.

my problem is that i am not able to execute some process after 100ms or 800ms. so how to write code for that.

Please help me, its very urgent.

Thanks in Advance
