Hi!
I have just begun to test the array_veneer class in MFCSTL. I use STLSoft
1.8.3 with Visual C++ 7.0.
I encountered problems when writing simple test programs. First I wanted
to apply std::sort to array_veneer:
struct MyTrait
{
typedef int value_type;
typedef int arg_type;
};
.
.
.
mfcstl::array_veneer<CArray<int>, MyTrait> av;
std::sort(av.begin(), av.end());
This fails to compile (six errors).
Ok, next test: Try to use std::back_inserter with array_veneer:
mfcstl::array_veneer<CArray<int>, MyTrait> av1;
mfcstl::array_veneer<CArray<int>, MyTrait> av2;
std::copy(av1.begin(), av1.end(), std::back_inserter(av2));
Fails to compile too (the compiler is complaining that reference is not a
member of array_veneer)
BTW, by simply creating an array_veneer like above (and nothing else), I
get two warnings saying that the copy constructor and the copy assignment
operator could not be created. Is that normal?
And, while I am at it: Why does the array_adaptor class only have a
const_iterator, not an iterator, and no push_back?
So Long...

First, let me say that MFCSTL has had very little input over the
last couple of years, as is probably evident by the code.
If you can post a sample file showing what you want to achieve, I'll
be able to comment on whether it's possible and, if it is, I would
think a fix will be forthcoming. ;-)
Cheers
Matthew
P.S. I'm thinking of renaming several 'veneer' classes, so changes
to meet your requirements might tie in quite nicely.

Hi Matthew!If you can post a sample file showing what you want to achieve, I'll be able to comment on whether it's possible and, if it is, I would think a fix will be forthcoming. ;-)Well, what Im'm trying to achieve is basically what I have posted: Apply STL algorithms to MFC CArray, with array_veneer and array_adaptor. ;-) We have a third party library here that takes and returns CArrays (and its specialisations). Right now, I am copying the CArrays to vectors and back, whenever I want to use STL algorithms, I was hoping that with MFCSTL I could skip that and could write code like CObArray Array = SomeLibraryFunc( ... ); mfcstl::array_adaptor<CObArray> Adapt; std::sort(Adapt.begin(), Adapt.end(), MyPred); Or like mfcstl::array_veneer<CObArray> Ven; std::copy(SomeSource.begin(), SomeSource.end(), std::back_inserter(Ven)); SomeOtherLibraryFunc(Ven); // Takes CObArray as argument The first one fails because array_adaptor only supports const_iterator, not iterator. But std::sort also fails with array_veneer, although it should work, since array_veneer supports iterator, and it provides random access iterators. And std::back_inserter fails on both array_adaptor and array_veneer because array_adaptor does not have push_back and array_veneer does not have a reference typedef (probably const_reference would also be needed). For your convenience, I will post a small test project which illustrates the problems. So Long... Gabor

Got it FYI: I'm writing my next book, Extended STL, at the moment, and in a few days I'll be working on the material about adapting non-STL collections, so this'll be ideal material. As such, I think I may have some good news for you next week.
