c++builder内如何获得点图层内点的坐标

<P>   IMoRectangleDisp r=CoRectangle::Create();<BR>   IMoRecordsetDisp recs;<BR>   IMoPointDisp point=CoPoint::Create();;<BR>   recs = g_layer->Records;<BR>   recs->MoveFirst();<BR>    while(!recs->EOF_)<BR>    {<BR>            recs->MoveNext();<BR>    }</P>
<P>我就不知道如何获得recs的点坐标了,放在point内</P>
