well, i wrote a program in c++. from the program, i open a web site written in php. then i pass data to it, and populate some fields in a form on the site. the only say i can figure out how to do it is by creating a long string, first with the web site name, then a "?", and then append the data i want to pass. the problems are: 1. the person can see all the data in the address bar at the top, and 2. they can change the data by just changing the address bar and refreshing. i need a way to do it that either encrypts or hides the info in the address bar, or to pass the info another way besides that big long string. for those of you that know c++, i am using "shell execute" to open the web site from my program. i need help.
