Re: [WIN] copy SIMPLE combo box selection into clipboard

Matt, anyone,

I tried using your second suggestion, after finding "EM_SETSEL", which I
think is needed to cause text to be "selected" so it can be copied to
clipboard, but I couldn't make it work.

Here's what I found about "selecting" text to copy to clipboard, don't
really know from where 'cause I couldn't find it again except in a file I
saved:
"The EM_SETSEL message selects a range of characters in an edit control. You
can send this message to either an edit control or a rich edit control."

Here's what I tried, maybe you can see what I've done wrong?

<code snippet follows>

global procedure W32RoutinesCombo_onChange ()
integer dummy

-- writes the text from selected item in combo box into "hidden" edit
control:
    -- (this *works*, at *least* when hidden edit is visible)
  wPuts(HiddenEditLine, getItem(W32RoutinesCombo,
       getIndex(W32RoutinesCombo)))

-- selects *all* the text in the hidden edit control?
   -- (I don't see any "selection" occur in the visible "hidden" edit
control)
   -- (tried other start/end values too, no result; 0,-1 is supposed to be
"select all")
dummy = sendMessage(HiddenEditLine,EM_SETSEL,0,-1)

-- copies selected(?) text in hidden edit control to clipboard:
   -- (but it doesn't, because "paste" doesn't paste what was in hidden
edit!)
copy(HiddenEditLine)

-- sets focus back to real editor:
  setFocus(mle)

end procedure
onChange[W32RoutinesCombo] = routine_id("W32RoutinesCombo_onChange")

<code snippet ends>

Any ideas??

Dan
