I call
ProcessInformationCopyDictionary
(&psn, kProcessDictionaryIncludeAllInformationMask);
but if the application has moved since it was launched, the result
of this
call in the CFBundleExecutable and BundlePath keys is wrong. The
values
contain the original location of the application.
So...
NSString *bundlePath = [dict objectForKey:@"BundlePath"];
if (bundlePath)
{
bundle = [NSBundle bundleWithPath:bundlePath];
}
Does not work.
How can I get the real current location of a file from the Process
Serial
Number?
I need to do this because my app is a system pref pane and when one
installs
a pref pane over the top of an existing one, the existing one is
automatically moved to a tmp location by System Preferences. I need to
determine if the running helper app is a different version form the
one
being installed... And need to get at the help app's bundle.
I suppose I could assume that if I can't obtain a real location for
the
running helper app, that it has been moved and I should send a quit
AppleEvent to it, but this doesn't seem like the best way.
Any ideas?
Thanks,
Trygve
I think it exists a standard Apple Event to retrieve a process
version. (get «vers»)
But you can also add a custom "get version" Apple Event handler to
your helper and use it to retrieve the version from your pref pane.
