AT&T Natural Voices ... and Visual Studio.net

["Stuart Booth" <stuart@xxxxxxx>]

I don't suppose anybody's tried invoking the Natural Voices C++ SDK from
Visual 
Studio.net have they? It comes with libraries compiled with Visual
Studio6.

I posted some of the following to the Natural Voices forum but have to say
it 
doesn't look that lively a place. I was hoping to invoke Natural Voices
from C# or 
maybe managed C++, but it's now looking like I'll need to call onto some
VC6 
compiled unmanaged C++.

Suggest you stop reading now if the sight of C++ code sends you to sleep !

On trying to compile with MS VS.net I get what looks like a standard
template 
library error (or 4): 

TTSDesktopPlayer error LNK2019: unresolved external symbol "void
__cdecl 
std::_Xlen(void)" ... 

After installing VS6 and the CRT source I found a global definition of
_Xlen and 
_Xran that appears to be missing from VS.net, so I added this:

namespace std // VS6 uses _STD_BEGIN
{
            // report a
length_error
_CRTIMP2 void __cdecl _Xlen()
      {_THROW(length_error, "string too
long"); }

            // report an
out_of_range error
_CRTIMP2 void __cdecl _Xran()
      {_THROW(out_of_range, "invalid string
position"); }

}; // VS6 uses _STD_END

Sure enough, this got things compiling. But I get as far as this in 
TTSSampleEngine.h before an error result is returned:

class      CSampleEngine : ...
:
virtual TTS_RESULT      Create (...)
{
    : stuff elided
    // Initialize the engine
    //
    result = this->m_pEngine->Initialize();
    :
}

This is returning an error result: 0x80040008

Now, if I've interpreted MAKE_TTS_RESULT correctly that's a
TTS_EXCEPTION.

Not at all sure how I can get around this. Possibly I just can't. Any 
thoughts/solutions anyone?
