TBoundPointerProperty.operator!=(_InterfacePtr) (Compact 2013)

3/28/2014

The != overloaded operator determines whether a pointer that is contained in a TBoundPointerProperty<PropertyType> object points to an object at a memory address that is different from the address of an object pointed to by another pointer.

Syntax

template<typename _InterfacePtr>bool operator!=(
_InterfacePtr p)

Parameters

• p
  [in] Pointer to compare with the pointer that is contained in the TBoundPointerProperty<PropertyType> object.

Return Value

Returns true if the pointer contained in a TBoundPointerProperty<PropertyType> object points to an object at a memory address that is different from the address of the object pointed to by the pointer in the p parameter; otherwise, returns false.

Remarks

The _InterfacePtr type must inherit from IUnknown. To compare two pointers of the same type, the type of the pointer in the p parameter must be the type that you specified in the PropertyType template parameter of TBoundPointerProperty<PropertyType>.

When you use the != overloaded operator for a TBoundPointerProperty<PropertyType>, use the operator as a function and use the p parameter as a function argument instead of using it as an operand in a C++ expression, as follows:

CHK_BOOL(pValue1->operator !=(pValue2));
