I want to create a simple starter for my applications.
it will check the myapp.exe file (timestamp,size,date or etc) on the server side and compare with client side myapp.exe file . if server side myapp.exe is newer version than client side exe version ,then it will copy new version exe file to the client pc .

How can i do this ?

PS :
i know Nick Neklioudov launcher and Ramani's (from tek-tips.com) application starter . but Ramanis codes runs the server side exe file :( (or i've a some mistakes) .

About Nick's launcher i've no experience
