I have a form with a treeview control. This form also have a 'cancel' commandbutton wich in 'click' event has this code:

'thisform.release()

If the treeview has the focus, the commandbutton doesnt works with the 'esc' key.
I've tried solve this with the 'keypress' event in the treeview:

if nkeyascii = 27
thisform.commandbuttonname.click()
endif

this works. but after closing form, VFP gives an error.
I've tried too adding this code in the commandbutton click event:

thisform.removeobject("treeviewname")
thisform.release()

but the error continue.

¿Does anyone knows solution?
