Operator Overloading

VB does not support operator overloading
This permits user-defined operator implementations
You can redefine the function of most built-in operators globally or on a class by class basis
Overloaded operators are implemented as functions

class MyDate 
{ 
   private m_Day; 
   private m_Month; 
   private m_Year; 

   bool operator == (const myDate mdate); 
   bool operator != (const MyDate mdate); 
} 

bool MyDate :: operator==(const MyDate mdate) 
{ 
   return !(this -> operator == (mdate)); 
} 
bool MyDate :: operator!=(const MyDate mdate) 
{ 
   return (MyDate.m_Day == this.m_Day) && 
             (MyDate.m_Month == this.m_Month) && 
             (MyDate.m_Year == this.m_Year); 
}
