Because the software keeps testing upgrades, it is not good to download new versions, so I want to join the automatic upgrade function. After writing, I feel that it is better to write it separately, make a general software upgrade tool, from INI Read the corresponding information in the file, then upgrade, so no matter what software can be upgraded automatically! Basically, completely use the API function, it is estimated that INI read and write, registry read and write, winnet.dll, etc., now write it now!
