I think it uses the uninstall info in the uninstall folder in your config folder to do its version checking. I could be wrong about this, though.

You copy that object and set those in your script's local copy to the current version and location of the script info XML. I don't know about the update check in the add/remove dialog though, it works with apps disabled so I'm presuming it doesn't use the toolkit.

However, the way most scripts are written, this isn't done *until* the ini is checked and, since there's no way for the GW Toolkit to automatically grab the update URL, there is something in the middle that I'm not understanding, and I need to. Clearly it does not use the ini check, yet how is it able to get the appropriate script update URL in such scripts that do not expose it unless the ini conditions are met? Do you see what I'm trying to understand?

There's no need for the "Add or Remove apps" to check in the .ini file to see about automatic updates as the user just instructed it to go check. the only other time it checks is when the app itself does the checking, and that's when the .ini comes into play. As for where to get the update from ... that indeed would have to be using app central as you too guessed ... there just isn't any other information it would have access to. If you don't want to use app central then the app of course could handle things itself, but it's a shame you can't get WE to handle it here or at least disable it altogether so it wouldn't incorrectly tell the user there's no update. but we'd need a change in the package manager and the .wepm format for it to be able to do anything like that ... or maybe some redirection type of functionality on the part of app central so it could be told to go get the xml for the update from some other address if you didn't want to store the updates there on app central. I guess that's what this is about, not storing them on app central?

The trouble with that line of reasoning is that, when most CheckForUpdate functions are written, they read the ini file of the script in question to determine whether updates should be checked on script's start or not. Yet, the add/remove update function runs through scripts and successfully checks for updates even when there is no ini file for the script in question and works even while the script is already running. That suggests to me that it might be calling the check for update code, but is somehow either using its own method or else is faking the ini file event for that update check. If it's using its own method, I need to understand how it gets the script's URL (since that's exposed in the function written within the script). I may need to do some internal script hosting, so I need to understand exactly how this works so that all update functions will point to the server they'll have to use. Hopefully it's not hard-wired to check app central somehow.

Is this what you were looking for?

I have a quick question about the package manager. How does the package manager check for updates? I've read the docs for GW Toolkit, and I understand how the CheckForUpdates object works. What I don't understand is how the package manager itself checks for updates. Does it fire off a CheckForUpdates sequence on each app, or does it work via some other method and where do I find docs for it if it doesn't use the GW Toolkit? Thanks
