用C及ftp实现软件自动升级。通过在服务器端建立FTP服务,实现远程主机的文件更新. 软件启动过程连接服务器,获得软件文件更新列表(此步省略),进行本地文件更新 启动过程进行系统调用执行批处理文件ftpget.bat,调用方式system( "e:ftpget.bat" ) 文件ftpget.bat负责连接服务器下载所需文件,并完成文件的更新-C ftp software and automatic upgrades. Through the establishment of FTP server, remote mainframe file updates. Software startup process server connectivity, access to software updates list (this step is optional), a local paper started the process of updating system calls for the implementation of batch file ftpget.bat, call mode system ( "e : ftpget.bat") documents ftpget.bat for connecting servers to download the necessary documents, and complete the document update
