Re: Launch Command

[Sarah]

Hi Roger,

I have actually been following this thread, but before it had seemed to 
me that your copy of TextEdit was in a folder called "GetIt". When your 
AppleScript confirmed that is was really in your normal Applications 
folder, it seemed that you had just been looking in the wrong place :-)

Now you have got me intrigued, so I wrote some scripts to help you work 
out what is going on. If you want me to send my demo stack, let me know:

Create a new stack and make 2 fields and 2 buttons:
In field 1, put the following Applescript:
tell application "Finder"
        choose file with prompt "Find TextEdit"
end tell
Leave field 2 empty.

Set button 1's script to:
on mouseUp
  do fld 1 as AppleScript
  put the result into appPath
  replace ":" with "/" in appPath
  replace quote with "" in appPath
  delete word 1 of appPath  -- alias
  delete last char of appPath -- :
  put "/" before appPath
  put appPath into fld 2
  launch appPath
  put the result
end mouseUp
Set button 2's script to:
on mouseUp
  launch fld 2
end mouseUp
(Usually I would give me field's descriptive names, but as this is only 
a test, I didn't bother.)

Now click button 1 - you should get a standard file selector dialog 
box. Choose TextEdit and click "OK". TextEdit should launch and the 
correct Revolution path to it should go into field 2. If you quit 
TextEdit and then click button 2, TextEdit should launch automatically 
without any file selection.

Using AppleScript's file selector works better for OS X app since it 
seems to understand better that they need to be treated as files event 
though they are really applications.

Let's hope it works this time :-)

Thanks, Sarah.  You've joined this thread on the second or third 
revolution.  I started with slashes (/) and I've known all along where 
the application is, but I can't get the Launch Command to work.  
launch "Macintosh HD/Applications/TextEdit.app" does not work on my 
OSX 10.2.4 running Revolution 1.1.1.   I guess no one else has this 
problem and I must appear to be a nut case.  Oh well!!

In order to be consistent across all platforms, Revolution uses a 
slash
"/" as the delimiter for file paths, in your case over-riding the
normal Mac colon ":".

Now that you have located the application, I think the following 
should
work:
	launch "Macintosh HD/Applications/TextEdit.app"	(Rev 1.1.1)
or	launch "/Applications/TextEdit.app"				(Rev 2.0)

Note that because of the peculiar nature of OS X application bundles,
checking for the existence of a file will fail. Check instead for a
folder if you are looking for an application.
e.g. there is a file "Macintosh HD/Applications/TextEdit.app"  -- 
false
	there is a folder "Macintosh HD/Applications/TextEdit.app"  -- true

Hope this helps,
Sarah

Ok, At least I can get the result:   "Macintosh
HD:Applications:TextEdit.app:"
If I then type:

			launch "Macintosh HD:Applications:TextEdit.app:"

into the message box, I get error-35.  What the heck is going on???

Thanks, Roger
