Replaces vertices/points within a PointCollection.
[Visual Basic .NET] Public Sub ReplacePoints ( _ ByVal pPointCollection As IPointCollection4, _ ByVal Index As Integer, _ ByVal goingAway As Integer, _ ByRef newPoints As IPoint[] _ )
[C#] public void ReplacePoints ( IPointCollection4 pPointCollection, int Index, int goingAway, ref IPoint[] newPoints );
[C++]
HRESULT ReplacePoints(
IPointCollection4* pPointCollection,
long Index,
long goingAway,
SAFEARRAY(IPoint)** newPoints
);
[C++] Parameters pPointCollection [in]
pPointCollection is a parameter of type IPointCollection4* Index
Index is a parameter of type long goingAway
goingAway is a parameter of type long newPoints [in]
newPoints is a parameter of type SAFEARRAY(IPoint*)*
All development languages compatible version of IPointCollection::ReplacePoints .
