I made the mistake of selecting web based help or soemthing when I got
prompted for what help system I wanted to use.
DON’T DO THIS !!! Its like it searches some bizare website and its totally
useless.
Yesterday I was searching on VarType.got VB help !!! What the HELL is
that about??

I have / had the same problem Jeremy.
I think I have the solution. Open help. Go to Tools | Options. Select
help - online on the left and change it from Online first to local first.
Hope that fixes it !

I've got the help working right now in d2007, but occasionally it doesn't.
It just comes up with some message like 'not in index' or similar.
We had a brief problem with a DBISAM release which was fixed straight away,
see below. It might be worth you trying to re-register the help in a similar
Hi
I have an annoying issue where when I save a project (save all) I get
the following error (always)
'Unable to rename 'c:\Dev\path\path2\ChreosClient.tlb' to

I can delete the file in _History and it does save ok, but the next time
I get the
Sound like you have create privs to the directory on your account, but
not modify...
This could be caused by the history files be logged into a source safe,
that marks them as read only.. deleting them would then allow you to
recreate the file.
Just a guess however...

If you have reproducible case - or even better find the solution - I
suggest you log it in QC.

Hi All. This is a question that might be infulenced by some serious lack of
sleep :-)
I have a funtion. Its return result is a TStringlist.
In my code I create a TStringlist then add my values to it, then pass this
to the RESULT varaible for the function.
Now, this is prob. an obvious answer

Actually in D2006/D2007 it does not work. You just use FastMM instead -
which has the equivalent options when running in Debug mode.

If the function returns a TStringList then it should be the responsibility
of the caller of that function to FREE the returned TStringList after it has
finished using it. You cannot free it inside the function.

Hi
Your code would leak. You are creating an object and not freeing it.
The calling function that retrieves the result must handle the freeing
of the object.
It might be clearer if you just change the function to a procedure that
takes a TStringList as a parameter. i.e
//Replacement
Still no Help at all. Where can I go to resolve this, or anyone got any
suggestions where to troubleshoot - eg what are the help files called and
where are they located so I can check they are there, and where are the
settings where the IDE goes to look for them??
(The only non-standard thing I
I would go along with Robert, you should not return complex types from
functions that create them, It makes the code messy, you create it in
one place and free it in another. Any sort of code analyser would also
complain about this. You could return a string = stringlist.text and
assign it
I would endorse Rob's answer here.
I don't consider it just a question of potential leaks, it's about
making the intentions of your code clear.
The intention of who has the responsibility for object lifetime is much,
much clearer in Delphi if your caller creates the Stringlist that it
wants
You guys don't consider a constructor a function then?
I think its totally stylistic, if you want to have functions returning
objects fine, just make it plain that they do,

David asked:

Yes, it does. I'm guessing they're referring to the IDispose interface
and pattern which Delphi.NET automagically maps calls to Free onto so
that resources _other_ then memory get released early.
question I knowbut the more I thought about it the more
uncertain I becameI really need some sleep so that prob. the real
probelm :-)

I do consider a constructor a function to some extent, but it's a
function which has compiler support.
I.e. the compiler guarantees to tidy up a partially constructed result
object if an exception gets raised in the constructor.
Also, everybody knows that a constructor returns a complex object;
Note for clarity, although I think we all understand this anyway.
What we're talking about here is a function returning _and handing off_
an object.
This is different to exposing an object (e.g. a StringList) as a
property of a class, e.g. the Items property of a combobox or similar.
In that
Warm fuzzy feelings :)

That code's safe from a memory POV, but I wouldn't have coded it like
that personally, because to me, the intentions aren't clear. I believe

The downside to having creator functions returning objects is that you
have to duplicate the code in
you have to duplicate the code in TObject.Create to ensure safety
What I meant was the ClassHandleException code which runs when an exception
occurs during a constructor.

Hi
The solution is to use interfaces, but if you don't it would be
difficult to implement a factory pattern
There is this thing in OO language users which seems to be the muddy
area between scalars and objects,
ie is a TStringList a simple object or a complex scalar, of course it
doesn't help
Hi Guys,
Hope you don't mind me sticking my nose in here. Firstly I agree with
the sentiment that you should try and avoid creating objects in one
place and freeing in another, however I don't think that this situation
represents that, think of a function that returns a class as a factory
SignatureI think PopulateList should be guarded by try.
Procedure DoSomthing;
Var
List : TStrings;
Begin
List := TStringList.Create;
try
PopulateList(List);
if List.Count 0 then
begin
.do lots of stuff with the list
End;
Finally
List.Free;
End;
End;
I would write
Fair enough, although you can't really talk about where the variable
is declared, since we're talking about multiple variable references to
the same object instance.
To me, some of the examples here today just smell slightly bad in
Delphi, and that's why I personally avoid them; I believe that
It isn't different, but that's because:
List := TStringList.Create;
PopulateList(List);
try
if List.Count 0 then
begin
.do lots of stuff with the list
End;
Finally
List.Free;
End;
is not safe. You need to move the PopulateList(List) inside the try/finally,
and

And reference counting sucks (esp after a few beers), but is better than

Hmm,
Have never read anything about CSS - I give that to someone else.
Mind you, I saw the acid2 test the other day, which was a very
interesting compare of CSS abilities by the browsers - would be
interesting and a long read of the css that produces that face. Only
opera had success!

Hi C(K)arl,
Sure PopulateList could be in the try finally block (probably better in
a nested except block actually), but the rest of what you say does not
make sense for this function. Perhaps you are mixing up the 2 different
functions?
I purposely didn't add exception handling to the
42 matches
