There's one Launch Services function which returns paths for all copies of all applications which meet a certain criterion: LSCopyApplicationURLsForURL(). You can "mark" your applications by having them claim some bizarre fake URL scheme, such as "com-yourcompany-yourapp-bogus-url-scheme". Then, you can use LSCopyApplicationURLsForURL() to search for all applications which can handle the URL "com-yourcompany-yourapp-bogus-url-scheme:junk". Yes, this is a gross hack. Yes, it can only be used in situations where you've planned for it in advance – you have to have marked your apps. If you're adding a feature to a new version of your app that relies on this, then the old versions won't have been marked. But it's the only public API that can do this. Launch Services definitely remembers more than the most recently recognized version, as you can see by running: /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -dump Cheers, Ken _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
