Hello:
As a self-taught Delphi user that has used D5, D7 and now D2007 over the
last 9 years, I still feel that I'm a newbie about many issues. Here's
one I need help on:
When moving a big project from D7 to D2007, I updated all the 3rd party
code to their most recent code, but in so doing I forgot that there were
a handful of pas files that I had to make changes to so that everything
worked correctly. Last night I had to add a couple of lines of code to
VirtualTrees.pas to check if a particular object (a tree node) was nil
or not when called otherwise it is possible that users who click on
checked nodes quickly, but miss the check box could end up with an error.
What I want to avoid is what happened in this transition from D7 to
D2007--I spent many hours trying to figure out what went wrong, only to
discover that it was I who made changes to the code so that things
worked as expected. In general I really dislike changing 3rd party code
because of this. Now, my question is how does one properly manage this?
I added documentation in my code to indicate I did this, plus in the 3rd
party pas, used a unique line identifier so that I can check for my own
code changes, but that really is not enough. Should I add the unit to
the project or move over the changed copy to my project and add that, or
something else?
Thank you for any advice,
Chuck Belanger.
