If Connected to the internet

I need a program that looks to see if my computer has an active connection to the internet (I use (at)home service ([login to view URL]) so I am connected 24 hours all day by cable modem - but sometimes the cable service goes down)if it is connected I need the program to call another program (eg. [login to view URL])... If the internet is down I need the program to "end" (basically do nothing) -It does not matter what language the program is written in.... but I need it to be an .exe file.....PEOPLE HAVE POSTED AND SENT LOTS OF THINGS THAT DO NOT WORK ... HERE IS THE ONE THAT WORKED THE BEST... THE PERSON HAD TOLD ME THAT THEY CAN MODIFY IT SO THAT IT READS FROM AN [login to view URL] FILE WHICH PROGRAM TO EXECUTE "IF THERE IS AN ACTIVE CONNECTION"... IF NO ACTIVE CONNECTION "IT DOES NOTHING" AFTER THE FILE OPENS CHECKS AND DOES EITHER... IT CLOSES..(HOWEVER, I HAVE BEEN WAITING FOR THIS PERSON TO GET BACK TO ME.. AND I GUESS THEY HAVE BEEN BUSY FOR THE LAST 10 HOURS AND I CAN NOT WAIT TOO MUCH LONGER- AFTER UNZIPPING YOU WILL HAVE TO CHANGE THE EXTENSION BACK TO .EXE TO SEE IT WORK ## Deliverables ASAP (1 day if possible) ## Deadline information The program has to work!
