Can I close a preview window on my button handler?

[integtech]

Hi, Dears.

I am creating a multi-plot module.

I am trying to create previous, next, and close buttons on my form applied to the preview window.

Is it possible?

This is my code for single plot preview.

PlotEngine pe = PlotFactory.CreatePreviewEngine((int)PreviewEngineFlags.Plot);
using (pe)
{
    PlotProgressDialog ppd = new PlotProgressDialog(false, 1, true);
    using (ppd)
    {
        ppd.set_PlotMsgString(
            PlotMessageIndex.DialogTitle,
            "Custom Plot Progress"
        );
        ppd.set_PlotMsgString(
            PlotMessageIndex.CancelJobButtonMessage,
            "Cancel Job"
        );
        ppd.set_PlotMsgString(
            PlotMessageIndex.CancelSheetButtonMessage,
            "Cancel Sheet"
        );
        ppd.set_PlotMsgString(
            PlotMessageIndex.SheetSetProgressCaption,
            "Sheet Set Progress"
        );
        ppd.set_PlotMsgString(
            PlotMessageIndex.SheetProgressCaption,
            "Sheet Progress"
        );
        ppd.LowerPlotProgressRange = 0;
        ppd.UpperPlotProgressRange = 100;
        ppd.PlotProgressPos = 0;

        ppd.OnBeginPlot();
        ppd.IsVisible = true;
        pe.BeginPlot(ppd, null);

        pe.BeginDocument(
            pi,
            doc.Name,
            null,
            1,
            true, // Let's plot to file
            "d:\\test-output"
        );

        ppd.OnBeginSheet();
        ppd.LowerSheetProgressRange = 0;
        ppd.UpperSheetProgressRange = 100;
        ppd.SheetProgressPos = 0;

        PlotPageInfo ppi = new PlotPageInfo();
        pe.BeginPage(
            ppi,
            pi,
            true,
            null
        );

        pe.BeginGenerateGraphics(null);
        pe.EndGenerateGraphics(null);

        PreviewEndPlotInfo pepi = new PreviewEndPlotInfo();
        pe.EndPage(pepi);
        ppd.SheetProgressPos = 100;
        ppd.OnEndSheet();

        pe.EndDocument(null);

        ppd.PlotProgressPos = 100;
        ppd.OnEndPlot();
        pe.EndPlot(null);
    }
}

Is there a way to access the preview window and pass a close command to it?

How should I approach this problem?

Thanks for reading.
