Hi Everyone,
Yes, and as I had said before, (even though no update pop-ups since,) it
needs to inform the user what, which, app needs updating. For you have to go
and search all to find out which one the pop-up is flagging!

Hi Vic,
you're right; the info about what's installed, and what version it is on your
pc, is all part of the uninstall info.
Jacob, I understand your confusion: you want to know how it knows where to
find the updated version, so it can compare against what you have, to see if an
update is needed?
GW has set things up so that you can find this simply by specifying the apps
name as part of the url. The add/remove package manager takes the app's name
and creates the appropriate app central url, and then goes there to see if
there's an xml feed specifying the current version of this app on app central.
if it finds this, and finds the version is later on app central, then it
notifies the user about an update.
It's not quite as flexible as the method used inside the script itself, as
you can't specify where to look for the updates, but it does work and works
well; it would only not work if you didn't want to store your updates on app
central, and the only reason I could think of for doing that would be some sort
of commercial app where you limit how it's distributed.
hth,
Chip

Aaron,
But where does it get the information about what packages you have installed
and the version numbers to compare to the App Central version numbers? It can't
get that from App Central.

Actually, the Add/Remove Packages check for updates routine gets all app
information (version, file size, update url, etc.) from App Central (review the
App Get code for a similar technique). This is hard coded in Window-Eyes.
