TBoundProperty.bool operator!=(PropertyType&) (Compact 7)

3/12/2014

The != overloaded operator determines whether the value contained in a TBoundProperty<PropertyType> object and another PropertyType value are different.

Syntax

bool operator!=(
PropertyType & value)

Parameters

• value
  [in] Pointer to a PropertyType value that is the operand on the right in a C++ expression.

Return Value

Returns true if the values of its operand on the left and operand on the right are different. Otherwise, returns false.

Remarks

The following example code uses the != overloaded operator to determine whether a PropertyType value is different from an integer value of 2.

#include "XamlRuntime.h"
#include "XRPropertyBag.h"

#define CHK_BOOL(x) { \
    if (!(x)) { \
        ASSERT(!"Assertion failed"); \
        return E_FAIL; \
    }}

void Check_relational_operator()
{
     // Create an XRValue that encapsulates an integer value that is 1.
     XRValue value1;
     value1.SetValue(1);

     // Define a TBoundProperty object that has PropertyType set to integer.
     TBoundProperty<int> propInt1;

     //Set the TBoundProperty value to the XRValue that encapsulates an integer.
     propInt1.Set(&value1);

     // Retrieve the new value as a PropertyType data type, which is an integer.
    int propValue = propInt1.Get();

     // Use the != operator to determine 
     // whether the PropertyType value is different from an integer value of 2.
     CHK_BOOL(propValue != 2);
}
