Well, I wasn't sure what the best group was for this question, but here 
goes.

The following object works perfectly under XP:

class TJMCSpeech
  {
    public:
   TJMCSpeech();             //Constructor
   ~TJMCSpeech();             //Destructor
   void Speak(String Words);  //Speak the input words in the string.
 private:
   HRESULT  hr;
   ISpVoice*  pVoice;
  };
//-------------------
//Constructor
TJMCSpeech::TJMCSpeech()
{
hr = S_OK;
pVoice = NULL;
::CoInitialize(NULL);

//Create a SAPI voice:
hr = CoCreateInstance( CLSID_SpVoice,NULL,CLSCTX_ALL,IID_ISpVoice,
        (void**)&pVoice);
}
//Destructor
TJMCSpeech::~TJMCSpeech()
{
if(SUCCEEDED(hr))
  pVoice->Release();

::CoUninitialize();
}
//---------------------------------------------------------------------------
void TJMCSpeech::Speak(String Words)
{
if(SUCCEEDED(hr))
   pVoice->Speak(L"Hello World",SPF_DEFAULT,NULL);
}
//--------------------------

For the sake of this example, I've replaced the use of "Words" in the call 
to Speak() by a fixed string, just to avoid any discussion about how I'm 
converting the String to a BSTR.

Simple right?

However, when I run it under Vista I get a floating point divide by zero 
when Speak() is called.

I've checked all pointers and as far as I can tell, they are non-NULL when 
used and hr indicates a successful creation.

I'm at a loss since I'm not able to upgrade to BDS 2008 at this time (I'm 
using BDS 2007).

Thanks for any help,
