-- Posted by harishanand at 12:26 pm on Oct. 1, 2004 Hello.. We have developed a Flash movie which is being distributed to our clients as an EXE and written on a CD. My client is concerned that if he submits it to A, A may copy the file from the CD and mail it to B, C, D, E...... as an attachment. I need to do whatever is necessary to make sure that the CD is required in order for the EXE to play. Pls recommend what is to be done ASAP. Thanks -- Posted by sriehl at 3:38 pm on Oct. 1, 2004 Even if you do figure it out, he will still be able to copy the cd and give it to his friends. -- Posted by Duekiller at 11:39 pm on Oct. 2, 2004 very simple. Have a text file called for example 'a.dat' on your cd then try to copy that file to the cd-rom to file called 'b.dat' this should return an error (because you cant write to a cd) then if an error is returned proceed to play the movie, but if the file did copy present an error message. -- Posted by the real anti christ at 8:15 pm on Oct. 22, 2004 is this distrbution legal? you don't sould like a legit proger (lol), the simplest way to do it would be to include a line or two requiring a flie from the cd on startup that is read only -- Posted by Dixebiim at 11:51 pm on Nov. 19, 2006 So true.
