I always liked the idea Borland had to include a start page with
links to updates and other info as they've been using in the last couple
versions of Delphi, so I try to scan thru it at least once a day to see what
new and interesting things are happening or talked about.
The other day I read a quick blob about "class helpers", which if I
remembered the name correctly, are classes that can be written to attach new
procedures and/or functions to a class already in use. Unfortunately not
much information was given and so I was hoping someone here might be able to
fill me in on what sounds to be something very useful. How exactly are they
formatted and used? What restrictions are there? Can they exist globally
for all projects if the unit they are declared in is placed in the lib path?
What kind of overhead does their use involve? And so on.
Also, I checked out just this morning a project in which an
alternative to the TStringList was offered. It's a very easy unit to
understand and make use of but I'm just a little curious about why or when
this would be of any real value? The author of the,
"stringlistRecordDemo.bdsproj" briefly mentions it not requiring a
try..except block to be placed around it, but looking back at former
projects I didn't find even one occurrence where I used a TStringList as
provided by Delphi in a lone situation...that is where it's creation was
protected by the same try...except block that was required or wanted to
protect adjacent code! So I guess I'm missing the point of this exercise.
Can someone add to this?
