ASP upgrade program instructions

This procedure is divided into two parts: 1. ASP file package Pack.asp put this program and put the program to package in a directory, then run Pack.asp, get pack.jpg and config.txt2, ASP online update, download, Installer Updata.asp This program can be used to check if there is available updates, and the same directory with Updata.asp exists above config.txt, because there is a current program installation date in Config, used to compare with the online program . Before use, modify the value of the URL variable in the updata.asp, so that it is equal to the URL you store the upgrade program, run Updata.asp to see if there is available updates, if there is, you can use the wizard step by step to download and install updates .

Remote address URL Save pack.jpg and config.txt available with Pack.asp

This program can be used to do upgrade procedures, of course, if the original installation directory is empty, it is a complete installer, ^ _ ^, you can also put UpData.asp in the home page of the background, so each login Can automatically check if there is available update

Note: Local or remote without config.txt will cause the program to be unavailable, and will consider adding this fault tolerance mechanism.
