OLE Object

What this page is about

Handle OLE objects in Aspose.Slides for C++: insert, link, update, and extract embedded content with C++ in PPT, PPTX, and ODP presentations.

This article demonstrates embedding a file as an OLE object and updating its data using Aspose.Slides for C++.

Add an OLE Object

Embed a PDF file into the presentation.

#include <DOM/IOleObjectFrame.h>
#include <DOM/IShapeCollection.h>
#include <DOM/ISlide.h>
#include <DOM/Presentation.h>
#include <Ole/OleEmbeddedDataInfo.h>
#include <system/io/file.h>
#include <system/object_ext.h>
#include <system/smart_ptr.h>
using namespace Aspose::Slides;
using namespace Aspose::Slides::DOM::Ole;
using namespace System;
using namespace System::IO;

static void AddOleObject()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto pdfData = File::ReadAllBytes(u"doc.pdf");
    auto dataInfo = MakeObject<OleEmbeddedDataInfo>(pdfData, u"pdf");
    auto oleFrame = slide->get_Shapes()->AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    presentation->Dispose();
}

Access an OLE Object

Retrieve the first OLE object frame on a slide.

#include <DOM/IOleObjectFrame.h>
#include <DOM/IShapeCollection.h>
#include <DOM/ISlide.h>
#include <DOM/Presentation.h>
#include <Ole/OleEmbeddedDataInfo.h>
#include <system/io/file.h>
#include <system/object_ext.h>
#include <system/smart_ptr.h>
using namespace Aspose::Slides;
using namespace Aspose::Slides::DOM::Ole;
using namespace System;
using namespace System::IO;

static void AccessOleObject()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto pdfData = File::ReadAllBytes(u"doc.pdf");
    auto dataInfo = MakeObject<OleEmbeddedDataInfo>(pdfData, u"pdf");
    auto oleFrame = slide->get_Shapes()->AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    auto firstOleFrame = SharedPtr<IOleObjectFrame>();
    for (auto&& shape : slide->get_Shapes())
    {
        if (ObjectExt::Is<IOleObjectFrame>(shape))
        {
            firstOleFrame = ExplicitCast<IOleObjectFrame>(shape);
            break;
        }
    }

    presentation->Dispose();
}

Remove an OLE Object

Delete an embedded OLE object from the slide.

#include <DOM/IOleObjectFrame.h>
#include <DOM/IShapeCollection.h>
#include <DOM/ISlide.h>
#include <DOM/Presentation.h>
#include <Ole/OleEmbeddedDataInfo.h>
#include <system/io/file.h>
#include <system/object_ext.h>
#include <system/smart_ptr.h>
using namespace Aspose::Slides;
using namespace Aspose::Slides::DOM::Ole;
using namespace System;
using namespace System::IO;

static void RemoveOleObject()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto pdfData = File::ReadAllBytes(u"doc.pdf");
    auto dataInfo = MakeObject<OleEmbeddedDataInfo>(pdfData, u"pdf");
    auto oleFrame = slide->get_Shapes()->AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    slide->get_Shapes()->Remove(oleFrame);

    presentation->Dispose();
}

Update OLE Object Data

Replace the data embedded in an existing OLE object.

#include <DOM/IOleObjectFrame.h>
#include <DOM/IShapeCollection.h>
#include <DOM/ISlide.h>
#include <DOM/Presentation.h>
#include <Ole/OleEmbeddedDataInfo.h>
#include <system/io/file.h>
#include <system/object_ext.h>
#include <system/smart_ptr.h>
using namespace Aspose::Slides;
using namespace Aspose::Slides::DOM::Ole;
using namespace System;
using namespace System::IO;

static void UpdateOleObjectData()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto pdfData = File::ReadAllBytes(u"doc.pdf");
    auto dataInfo = MakeObject<OleEmbeddedDataInfo>(pdfData, u"pdf");
    auto oleFrame = slide->get_Shapes()->AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    auto newData = File::ReadAllBytes(u"Picture.png");
    auto newDataInfo = MakeObject<OleEmbeddedDataInfo>(newData, u"png");
    oleFrame->SetEmbeddedData(newDataInfo);

    presentation->Dispose();
}
