Different result in LC 6 to LC 8 when copying field text into Excel?

Tiemo,

I’m not sure if this will help because I’m testing on Mac, but I did a little bit of experimenting with the new ‘rawClipboardData’, it allows plain text to be copied out of LC, just to prove it, here’s a button script copied via my now modified Script Buddy plugin…

on mouseUp
   local tClip

   if the selectedText is empty then
      set the clipBoardData["text"] to fld “myTextField"
   else
      copy the selectedText
   end if
   
   if the altKey is down then -- Convert the clipBoard to plain text
      put the clipBoardData["text"] into tClip
      lock the clipBoard
      ## Use some code lifted from the LiveCode Dictionary…
      set the rawClipBoardData to empty -- Clear ALL ClipboardData
      if the platform is "Linux" then set the rawClipboardData["text/plain;charset=utf-8"] \
            to textEncode(tClip, "UTF-8" ) -- Linux
      if the platform is "Win32" then set the rawClipboardData["CF_UNICODE"] \
            to textEncode(tClip, "UTF-16" ) -- Windows
      if the platform is "MacOS" then set the rawClipboardData["public.utf8-plain-text"] \
            to textEncode(tClip, "UTF-8" ) -- OSX
      unlock the clipboard
   end if
end mouseUp

At last, no extra line spacing! :-)

Normally when I paste from LC into Mail I see extra line spacing, and I would have to copy and paste via a plain text editor to remove it. Emptying the clipBoard and setting the rawClipboardData as above seems to work, on Mac at least, hopefully it should work with Excel on Windows too.

Paul
