Hello,
I found a reply by Peter Huang to a previous post quite valuable with regard
to referencing controls on a form by name using reflection. It made me
wonder when I would not use Reflection for this task (or any other similar
task). So, I thought I'd ask the question ... when is Reflection not an
appropriate solution (especially with regard to getting controls by name)?
Thanks!

Jack, So, I thought I'd ask the question ... when is Reflection not an
appropriate solution (especially with regard to getting controls by name)?
For me has this a simple answer *forever* when you don't need it. It is just
late binding.
In addition I don't see any problem to solve with it which cannot be done
better without it, with the exception maybe when you are building your own
compiler or something like that.

Reflection will only work in this case when there is a variable referencing
the control. It won't work for controls added at runtime which do not
belong to a member variable.

Thanks for the feedback. Previously, I loaded the controls into a hash table
when the form loaded. I guess your recommendation is to go back to that
method?

How did you know that, I had the idea to write that already in my first
message.

good, I can host it, but I can not reach the parent COM object from the
control (Parent property is null :( ).
I have stopped the control in the...

I understand that reflection allows me to discover the metadata of a
class at runtime (properties, methods etc). What I don't understand is
where this is useful. For example:
If I am the sole author of an application, I already know the metadata
about my classes - I wrote them. And even if I did not - Let's say I
buy a 3rd party class lib, it will be documented for me with that lib.
If I am part of a dev team, the same is true - If...

Hello all
Does anyone know of a good way to use reflection in c++?
I don't mean simply using rtti or dynamic casting.
I'm talking about java/c# style reflection where an actual instance of
an object can be constructed through reflection and method calls can be
made via the reflection apis.

I've been led to believe by several articles, particularly Eric Gunnerson's
C# Calling Code Dynamically, that calling a method dynamically through
Reflection was much slower than through a Delegate. My testing showed that
actually it was six times faster: 0.5 seconds for 100,000 iterations versus
3.1 seconds.
Can anyone explain why? Something in the way I coded it? I'd appreciate
any insights.
