Set Caption to OLE Icon

New get_SubstitutePictureTitle() and set_SubstitutePictureTitle() methods have been added to IOleObjectFrame and OleObjectFrame classes. It allows to get, set or change the caption of an OLE icon. The code snippet below shows a sample of creating Excel object and setting its caption.

auto presentation = System::MakeObject<Presentation>();
auto slide = presentation->get_Slide(0);

// Add an OLE object to the slide
auto allBytes = System::IO::File::ReadAllBytes(u"oleSourceFile.xlsx");
auto dataInfo = System::MakeObject<OleEmbeddedDataInfo>(allBytes, "xlsx");

auto oleFrame = slide->get_Shapes()->AddOleObjectFrame(20, 20, 50, 50, dataInfo);
    
// Add an image to the presentation's image collection
auto image = Images::FromFile(u"oleIconFile.ico");
auto ppImage = presentation->get_Images()->AddImage(image);
image->Dispose();

// Set the image as an icon for the OLE object
oleFrame->set_IsObjectIcon(true);
oleFrame->get_SubstitutePictureFormat()->get_Picture()->set_Image(ppImage);

// Set a caption to the OLE icon
oleFrame->set_SubstitutePictureTitle(u"Caption example");
