IGeometryEnvironment2.Pre81Compatibility Property (ArcObjects .NET 10.8 SDK)
|

Indicates if some geometric operations are compatible with releases previous to 8.1. When set to false, return errors for some illegal relational operations (default is true).
[Visual Basic .NET]
Public Property Pre81Compatibility As Boolean
[C#]
public bool Pre81Compatibility {get; set;}
[C++]
HRESULT get_Pre81Compatibility(
VARIANT_BOOL pre81Compatible
);
[C++]
HRESULT put_Pre81Compatibility(
Boolean* pre81Compatible
);
[C++] Parameters pre81Compatible
pre81Compatible is a parameter of type bool pre81Compatible [out, retval]
pre81Compatible is a parameter of type bool*
Returns and sets the flag indicating the preference for extending compatibility with pre-ArcInfo 8.1 releases at the cost of allowing improperly used IRelationalOperator comparisons to return meaningless false values.
If Pre81Compatibility = TRUE, meaningless comparisons of non-Clementini geometries using Clementini relational operators returns FALSE (even though no meaningful relation actual took place).
If Pre81Compatibility = FALSE, these comparisons will return an error message indicating that the attempted comparison is invalid and would not have returned meaningful results. By default, Pre81Compatibility = TRUE.
