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 :-)
