Hi,

  I am learning the Exception Handling in C++. I wrote a small program using

Exception Handling. I am using Vistual Studio 6.

  It is working fine in Win32 Debug build, but it is not catching the

exception in Win32Release mode.

int main(int argc, char* argv[])
{
  int i = 0;

  try
  {
       int m = 17/i;
  }
  catch(...)
  {
       cout<<"Main - Catch"<<endl;
  }
  cout <<"End of Main" <<endl;

  return 0;
}

Could you please explain, why the Exception is not caught in the
Win32Release mode.??

Access violation or a division by 0 are hard exception and not handled
as exception by C++.
However, Microsoft has added this support to their compiler; it seems to
be the case only in Debug mode which is sensible because it avoids
testing all division performed.

Michael
