[C++]

HRESULT GetPoints (
    [in, optional, defaultvalue(ISC_FirstElement)] long startingIndex,
    [in, optional, defaultvalue(ISC_AllElements)] long pointCount,
    [out, retval] VARIANT* Points
);

[Microsoft® Visual Basic® 6.0]

    [startingIndex As Long], _
    [pointCount As Long = -1] _
) As Variant

Parameters

startingIndex

[in, optional] The starting index within the array of points that make up the stroke. The default value ISC_FirstElement, defined in the ItemSelectionConstants enumeration type, specifies the first point.

pointCount

Return Value

HRESULT value Description
S_OK Success.
E_POINTER A parameter contained an invalid pointer.

Example

[Visual Basic 6.0]

This Visual Basic 6.0 example gets all of the point data from the IInkStrokeDisp, theStroke. This data is returned as an array of Long values in the form x1, y1, x2, y2, and so on, with each pair of values representing one point.

Dim ptStrokePoints () As Long
ptStrokePoints = theStroke.GetPoints()
