Post by Ludek » Mon 27 Jul 2009 08:29

AddRefStr failed (D:\Projects\Delphi\Dac\Common\Source\MemData.pas, Zeile 7780).

Code: Select all

I think, it is the same issue as http://www.devart.com/forums/viewtopic.php?p=47899 - it happened in the form also containing the dangerous .edit in drawcolumncell.
