fprintf (stderr, "Failed FormatMessage - MessageIndex = <%d>.\n", 0);
but when I run this on vc9(visual studio 2008)
an exception is thrown,How to handle the exception is the issue.
The exception condition will occur definitely but handling that is
what I need.In vc6 same code is working fine.

What is the exception thrown?

The general way of catching exceptions in C++ is by using try/catch, i.e.

try {
   ...
   code
   ...
}
catch( const std::exception & e ) {
    std::cerr << "*** ERROR: " << e.what() << std::endl;
}

exception handling already there, but still the below exception is
comming
First-chance exception at 0x7c91b21a in unittest.exe: 0xC0000005:
Access violation writing location 0x00000010.

My crystall ball tells me that stderr is not open. Is the program a
console application ? Normal windows applications need to freopen stderr
themselves.
