Hi How can i quit Application from other application ? I have following details ->application path Is there any API to send quit event to other application ? p2 > Hi > [quoted text clipped - 4 lines] > > Is there any API to send quit event to other application ? Send it a Quit Apple Event. Code for how to do this seems a bit scarce but this may get you started: http://developer.apple.com/documentation/AppleScript/Conceptual/AppleEvents/crea te_send_aepg/chapter_7_section_4.html  SignatureMichael Ash Rogue Amoeba Software > > Hi > > [quoted text clipped - 10 lines] > http://developer.apple.com/documentation/AppleScript/Conceptual/AppleEvents/cr > eate_send_aepg/chapter_7_section_4.html Robustly turning a string that happens to be a file system path into an identifier for a running process is the tricky part of this. I haven't been able to think of a truly reliable way to do it, although I can think of a couple of 99% solutions. > Robustly turning a string that happens to be a file system path into an > identifier for a running process is the tricky part of this.

Make an FSRef from the path, iterate over all processes and call GetProcessBundleLocation, return any which match, that should coverr everything.

Except for apps that moved since launch, depending on when and how the path the OP was handed was constructed. >> > Robustly turning a string that happens to be a file system path into an >> > identifier for a running process is the tricky part of this.

Well, if he has a path to where the app actually *is*, and not where it once *was*, then this will still work, since the FSRefs will follow the move. If he only has a path to where the app once was, then nothing short of a guessing game will work without a time machine. But I wouldn't count that in your 1%, because it's a pathological case, like saying that Spotlight won't find a file by name if you've changed the name.

Spotlight'll still work if you change the name of any number of nonterminal nodes in the path. People do rename volumes and folders from time to time. I think the real answer to "How can I terminate a process given a path" is "first look to see if you can get something better like a bundle ID or creator code." Even an alias would be more reliable. >> Well, if he has a path to where the app actually *is*, and not where it >> once *was*, then this will still work, since the FSRefs will follow the [quoted text clipped - 8 lines] > given a path" is "first look to see if you can get something better like > a bundle ID or creator code." Even an alias would be more reliable. Yes, a lot depends on where the path comes from. I had taken the "path to the app" as a given, rather than assuming it's "a path which was once to the app". If the path comes from, say, an open panel which just finished running then you're pretty safe, aside from the race conditions inherent in any use of paths which nobody seems to want to talk about. If the path comes out of preferences or something then you're right and it's just plain the wrong approach to use in the first place. Storing the bundle ID would be the right way to proceed in this case, IMO. SignatureMichael Ash Rogue Amoeba Software |
