I have developed a CD applicaiton that is to be installed on the client's PC once and only once. To make sure that it can only be installed once, I want the application to contact a PHP website via http and receive a positive (in case this is the first installation) or negative (otherwise) response.
Want I mean is: the app issues a http request, say htpp://www.someserver.com/path/script.php?param=value
, and the html output of this script is the confirmation or infirmation of the app installation.
I want this to be transparent to the user, i.e. no browser window, no visible TCppWebBrowser.
Any ideas on how to do that? (or, dou you have any other suggestion on how the installation can be validated just once?)
Thanks in advance,
