how to activate a chm file on a web applicaion

[kenny9239]

Hi, allI need to do a help function for an existing web appication written in php5. I was told to have a drop down list to choose help files and a submit button on the help page.After clicking the submit button, the applicaion will check whether the help file(chm format) is in client computer's specific directory. if the file is in client's computer the chm file will be activated. if the help file is not in client's computer, the web applicaion will ask user to downlaod the help file.My question is 1) how to activate the chm file? I dont know what tool (like javascript or php) that allow me to call a windows applciaion like Chm or words. 2) Im using WAMP envirnment. If I want to make the download works. Do I have to have a FTP server? Since WAMP doesnt come wiv FTP server, I wll have to get a FTP server up and running on my windows operation system. I will be grateful if I have any comment regarding to my issure.Thanks

Most web browsers can display CHM files, so you can just redirect the browser (or open a new window) to the location of the CHM.You don't need an FTP server to download files, unless you specifically want to use FTP. You can always just send it through HTTP if you redirect the client to a URL on your server.
