i want to ask about something..
i made a software using php , ajax and javscript..
now as any product i want to make updates on my software, when any updates is available, i want to let the user knows that there is a new update with a new version so the user can download it....
Example: like the update of mccafe, windows....etc..........
my idea is to use the webservice and let the software when loggin-in uses the webservice to check if there is any updates and tell the user with a message the version is updated,please download new version
but till now i can not make this webservice..
Any idea of using webservice or any other idea???????
