Re: Zero length vectors causing problems

[Daniele C. <dca...@in...>]

example:
/*
unsigned original_mask = _controlfp(0,0);
   unsigned mask = original_mask;

   mask|=(_EM_ZERODIVIDE);
   _controlfp(mask, _MCW_EM);
   */
CPrintDialog pd(FALSE);
         pd.GetDefaults();

         float a,r;
         a=0;

         r=1/a;

If I set HP laserjet 1100  like default  program crash. If  I canc /* and 
*/ program run fine.
With other printer I have not problem.See the documentation of _controlfp. 
Try my little sample... is more simple solve this.
All only in WIN 98!!
