try : lbl = getattr(self, curlabel)
except: # do other stuff your original code won't do
finally : lbl.Caption = "somestr"
I guess those three lines do what your original 3 do, but faster.
Or if you accept an Xtra line :
try :
lbl = getattr(self, curlabel)
lbl.Caption = "somestr"
except : pass # or some other line with xtra functionality
BTW didn't mean to pick a fight, though re-reading my post you might
