This basic installation example illustrates a file installation/acquisition method that provides developers with an easy-to-implement means of building across-the-web installation or updating into their products. This application first connects to HNDFILSV.APP to download an installation files list approved at the server end. Next it downloads the listed files and places them in the designated directories below the installer's configured target directory. Files are only downloaded when the CRC value provided for any file is different than the CRC of the file already installed. The server auto-encrypts and auto-compresses files at the request of this client and files are auto-decrypted and auto-decompressed on arrival. Replaced files are copied to the backup directory before replacement is made. When the download file is an .HZO container (built with HNDSETUP.APP), this client extracts it to the download directory, while honoring the sub-paths indicated by the .HZO contents. When the .HZO contains .EXE files, the application presents a run button which offers to let the user run the executables available. A configuration procedure in this application is provided in order to change the installation server as well as the local target and backup directories. The installer always recalls it's last installation log from the config menu. |
