The Key() event works well for that.

if not nChar = 3
   msgbox("ReadOnly Field")
   return false
endif
return

Something on those lines.

Hi All

This is a bit of Windows basics, I suppose.

In many forms I require a user to click an Edit button to get access to 
entryfields for editing.   It stops casual inadvertent changes, of 
course.    When not in Edit mode the fields are protected with

when = {|| false }

and, FWIW, I change the mousepointer to 1 (arrow).    I don't change the 
  enabled property (except for Checkboxes) as it changes the display.

I would like to make it possible for the user casually to highlight the 
text in an entryfield and to copy it to the clipboard (Ctrl+C), but 
without compromising its non-editable status.

Any thoughts?

Thanks, Greg:  that's interesting.    Testing shows up one hitch - it 
allows Ctrl+V Paste to overwrite the value.    Further testing shows 
that Ctrl+C and Ctrl+V do not trigger the key event handler, even if I 
don't have an Edit menu with Cut/Copy/Paste on the form, so the test
if not nChar = 3
is superfluous.

Otherwise it does what I want.   Any thoughts on intercepting Paste?

Hmm.. what version of dBASE and windows are you working with?

The keyboard / keycombo's are protected on mine system, ctrl-v, don't know 
why it wouldn't with yours BUT try this:
I can not control popup menus though.

As of right now I don't have an answer for the menu driven paste.

return

Just to be sure, are you using the Key()  or   onKey() ?
