Multiple program run and close with one batch file????

Hi All, 'Ive been searching for quite some time to solve a problem. I have a batch file to open 2 programs at once, which is great. I have another batch file to close these programs together, but what im trying to figure out is: Load both programs with the one batch file ( I have that figured out ) Close both programs when i click the 'Close' button on top right of window on 2nd loaded program. Here is my launch file: @echo off start firefox http://ebay.com/ start notepad @echo on exit Now how can i close both if i click on Notepads 'Close' button??? Any help with this would be very much appreciated. VR
