Is this a reference to the renamed cc file?  So that will mean that in the renamed cc file the we can add to existing code of function extcombox_onchange() method. The idea behind making a copy of the .cc file is that at that point it is your version of the software. If you want to go a different route, see below. > > I think the above does not imply inheritance. Or may be I am wrong. Another option might be to create a .cc file with constructor code of (NOTE: this should NOT be placed in the dUFLP folder, it should be in some folder with your own Custom Class files ...): set procedure to :dUFLP:ExtCombobox.cc class MG_ExtCombobox( oForm ) of ExtCombobox( oForm ) custom /*     Here you are using full inheritance: you can modify the way     the onChange() event handler works, and still inherit everything     else from the original source code. */ endclass I hope that helps.
