'operator' : no acceptable conversions from 'type1' to 'type2'

A conversion was not defined to convert an operand to the required type. If you’ve encountered this error on code which compiled with an earlier version of Visual C++, please read Technote: Improved Conformance to ANSI C++ for more information.

Define a constructor or conversion operator to make the required conversion.

The following is an example of this error:

class C
{
   public:
   C();       // no constructor with an int argument
} c;
class D
{
   public:
   D( int );
   D();
} d;
void main()
{
   c = 10;    // error
   d = 10;    // OK
}
