Simple update checker framework

[EntityReborn]

Here, I have designed a simple update checker framework using a few APIs, specifically InternetOpenURL to download the versions textfile to the users computer, then search the file for the needed information, using the GetPrivateProfileString API.

The versioning scheme used here is <MajorVersion>.<MinorVersion>.<BugfixVersion>, but this could be changed to suit your needs, for instance those who use compile dates as your versions, 2008.09.26 should work fine, or you could edit the class to remove BugFixVersion, and have for instance v1.02, etc.

I have commented in some areas, but the code is fairly straight forward, and should be easy to understand. The current setup has the program at version 1.0.0, and the file checks http://iamentity.10gbfreehost.com/versions.txt (my free webserver) which states the 'newest' version is 2.1.0.


Notes: one possible error could be if the file exists when its downloaded, and the file is locked (marked as in use). Even though I have added an error handler, using On Error Goto... this error still crashes the program.
Also, this will not work for trying to reference a file on the local computer directly, ie "C:\versions.txt".
Finally, the filename versions.txt is hardcoded, and shouldn't need changing, but feel free to do so. I don't forsee the need to expose this as a variable.
