Hi all,
I have a routine that has to check if two variants, v1 and v2, are holding
interfaces to the same underlying object. I've tried the following approaches
with the following results (assumption is that they do indeed point to the same
underlying object:
(1)
result := v1 = v2;

Another alternative is to wrapper the OLEVariant in an object before storing

Hi,
I trying to write a DLL from a Visual C specification and (not really knowing C
much at all) I need a little help with some of the conversion:
1) I presume I can convert all the straighforward #Defines into consts?
2) Can I convert the macro defines into functions? eg what would:
4) Can I ignore the #pragmas? There is only one (used in a couple of
places):
#pragma pack (push, 8) and #pragma pack (pop, 8)
Ouch - I think that forces stack push and pop's to align to 8 bytes. Not
sure tho. Depends if you are porting the code over, or just interfacing with
the DLL.

I agree that the the tree building logic should be seperate from the other
information logic. That's logical :-). The tree view is really just a view
into the data. My intention is to create descendant tree nodes (from my new
generic TTreeview, TTreenodes and TTreenode classes) that know what
Using helper objects doesn't mean, though, that you need to avoid
inheritance. In your case you could create descendant nodes for no other
reason than to store a helper object (and maybe carry out a few maintenance
operations). You could create a new custom node for each kind of helper
object,
given.

That may work, but now you have used up the object holder for each Node's
object. That means that your implementation cannot be descended from
correctly if that place holder is required in the descendant class. The
argument for using helper classes is fine but your new class shouldn't have
