/*=CHANGE:=============================================================*
To programmatically interact with the 3D graph you will need to first obtain 
the object handle. Use this handle to register event callback functions 
call methods or get and set properties of the 3D graph. 

Example Code:

    int                         i j;
    HRESULT                     __result;
    CAObjHandle                 graphObjHandle;
    CW3DGraphLibObj_CWPlots3D   plotsObjHandle;
    CW3DGraphLibObj_CWPlot3D    plotObjHandle;
    double                      zMatrix[10][10];
    VARIANT                     zMatrixV;

    GetObjHandleFromActiveXCtrl （panelHandle PANEL_GRAPH3D 
                                            &graphObjHandle）;

    __caErrChk（CW3DGraphLib__DCWGraph3DGetPlots （graphObjHandle NULL
                                            &plotsObjHandle））;
    __caErrChk（CW3DGraphLib_CWPlots3DItem （plotsObjHandle NULL
                                        CA_VariantLong（1） &plotObjHandle））;

    for （i=0; i<10; i++）
        for （j=0; j<10; j++）
            zMatrix[i][j] = （i*i） + （j*j）;
            
    __caErrChk（CA_VariantSet2DArray （&zMatrixV CAVT_DOUBLE 10 10
                               zMatrix））;

    __caErrChk（CW3DGraphLib_CWPlot3DPlot3DSimpleSurface （plotObjHandle NULL zMatrixV
                                              CA_DEFAULT_VAL））;

Error:
    CA_VariantClear（&zMatrixV）;
    CA_DiscardObjHandle（plotsObjHandle）;
    CA_DiscardObjHandle（plotObjHandle）;
