Many of the methods compare the current ActiveX value object, named Opaque, to another object of the same type. All of the custom methods return HRESULT, with a value of S_OK (success) or E_FAIL (failure).

(1 of 3)
HRESULT Compare([in] IOpaque *other, [out, retval] int *relationship)
Compares the current object to another object of the same type, returning:
0
-1
1
HRESULT Concat([in] IOpaque * other)
Concatenates another object of the same type to the current object. This method is usually implemented for string objects.
HRESULT Contains([in] IOpaque *other, [out, retval] BOOL *result)
Returns TRUE if the current object contains another object of the same type, or FALSE if it does not.
TRUE
FALSE
HRESULT Divide([in] IOpaque *other, [out, retval] IOpaque **new)
Returns a new object representing the division of the current object by another object of the same type.
HRESULT Equal([in] IOpaque *other, [out, retval] BOOL *result)
Returns TRUE if the current object is equal to another object of the same type, or FALSE if it is not.
HRESULT FromString([in] BSTR string)
Converts a character string to a new instance of the current object.
HRESULT GreaterThan([in] IOpaque *other,[out, retval] BOOL *result)
Returns TRUE if the current object is greater than another object of the same type, or FALSE if it is not.
HRESULT GreaterThanOrEqual([in] IOpaque *other,[out, retval] BOOL *result)
HRESULT Inter([in] IOpaque *other, [out, retval] IOpaque **new)
Returns a new object representing the points in common between the current object and another object of the same type.
HRESULT IsNull([out, retval] BOOL *result)
Returns TRUE if the current object is has a null value, or FALSE if it does not.
HRESULT LessThan([in] IOpaque *other,[out, retval] BOOL *result)
Returns TRUE if the current object is less than another object of the same type, or FALSE if it is not.
HRESULT LessThanOrEqual([in] IOpaque *other,[out, retval] BOOL *result)
Returns TRUE if the current object is less than or equal to another object of the same type, or FALSE if it is not.
HRESULT Minus([in] IOpaque *other, [out, retval] IOpaque **new)
Returns a new object representing the current object minus another object of the same type.
HRESULT Negate()
Usually negates the current object: makes a positive object negative, or a negative object positive.
HRESULT NotEqual([in] IOpaque *other, [out, retval] BOOL *result)
Returns TRUE if the current object is not equal to another object of the same type, or FALSE if it is.
HRESULT Overlap([in] IOpaque *other, [out, retval] BOOL *result)
Returns TRUE if the current object has any points in common with another object of the same type, or FALSE if it does not.
HRESULT Plus([in] IOpaque *other, [out, retval] IOpaque **new)
Returns a new object representing the current object plus another object of the same type.
HRESULT Positive()
Usually makes a negative object positive; a positive object remains positive.
HRESULT SetNullFlag()
Sets the current object to a null value.
HRESULT Size([out, retval] double *size)
Returns the size of the current object, in implementor-defined units.
HRESULT Times([in] IOpaque *other, [out, retval] IOpaque **new)
Returns a new object representing the current object times another object of the same type.
HRESULT ToString([out, retval] BSTR *string)
Converts the current object to a character string.
HRESULT Union([in] IOpaque *other, [out, retval] IOpaque **new)
Returns a new object representing the union of the current object and another object of the same type. This method is usually implemented for objects that represent areas.
HRESULT Within([in] IOpaque *other, [out, retval] BOOL *result)
Returns TRUE if the current object is within the other object, or FALSE if it is not.
