I had a need today to call an AppleScript from a cocoa app - and be able to target a specific handler inside that script. I read through all the NSAppleScript and NSappleEventDescriptor docs, read a few things on the web and was figuring I'd have to write something like this! Now I don't, and you have no idea how happy that makes me :) Thanks, Buzz. Whew!

For more info, see: http://developer.apple.com/qa/qa2001/qa1111.html And for a working formulation: http://www.cocoadev.com/index.pl?CallAppleScriptFunction Hope this helps - m. The fatal flaw is this line:

subroutineDescriptor = [NSAppleEventDescriptor descriptorWithString: handler];

It should be:

subroutineDescriptor = [NSAppleEventDescriptor descriptorWithString: [handler lowercaseString]];

Like kASAppleScriptSuite, kASSubroutineEvent, and keyASSubroutineName. I don't think it's required to set the targetDescriptor: parameter when making the Apple Event to send to a script. I just use +[NSAppleEventDescriptor nullDescriptor] and it works fine. Why not use symbolic names from instead of using hardcoded four character codes?
