Just be aware that the latest incarnation of new will not just
return a NULL pointer, but rather will throw an exception. So
it should be:

try
{
   char* pBuffer = new char[dwSize];
}
catch (...)
{
}

Also, don't forget to free the memory when you are done.

You might try asking this in the .language.cpp group. Lots of C++ gurus
hang out there and can tell you how to use a "safe" new.
