An interesting thought just occurred, almost totally unrelated to this thread.
Is a gb.db Result a collection or an array? It is hard to tell from the help
This class represents the result of a SQL request.
This class is not creatable.
This class acts like a read / write array.
This class is enu

No, the key values are important (to the rest o
Thanks to all for their interest an input here. At the very least it has
helped me to crystallize what my problem is.
I may have over generalised my problem. So I'll try to explain.
The issue is, as some have realised, the temporal order in which things are
added to the collection, not some or

I agree and that is not my requirement. I only need to know when
If the key values aren't important then use something like
Collection.add(Value,str(Collection.count+1))
then you can access any given item by
Value=Collection[str(Index)]

Sorry, meant to attach a screen shot of the issue. So here it is.

Hi Folks,
I've had an issue for sometime now and I haven't found the solution yet.
Anytime I get an error message in the IDE it is displayed as a pale yellow
background with white text. It is almost impossible to read! Is there some
way to change the font color or background color of just the erro
Hi folks.
I'm trying to implement a "decoration chain", but until now I can't get
success.
Let me explain the problem in detail.
I have a class C, that is decorated by the class B, that is decorated by
the class A. So, from the point of view of the client class, the class A
must respond to messa
In some languages, FOR EACH doesn't guaranty the order of the items
processed. It only guaranties you will process each item in the collection.
I think it is a bad habit to use For Each when order of processing is
important. Unless you are using an array or other data structure that is
known to mai

Thanks Fabien, I have installed Gambas3 rev 6301, i have the example
SystemTray but does not work with component gb.gtk3 gb.gui, when I run it
I get the following error:

OK, thanks for the answer! But can you elaborate bit further? If the
insertion order is no longer kept, then what dictates the order "For Each"
will enumerate the items? Order of memory addresses?
I mean would the enumeration order be unchanging, but when new item is
added it would be inserted in

That is my understanding also. But they always seems to be in order they
have been added, when you iterate them with "For Each ...".
What would cause the disorder?
