Insertando un archivo WAV como Objeto Ole con C++

Aspose.Cells proporciona la funcionalidad para agregar diferentes tipos de objetos OLE en hojas de Excel. Veremos en los siguientes ejemplos cómo agregar un archivo WAV como objeto OLE usando API simples proporcionadas por Aspose.Cells.

#include <iostream>
#include <fstream>
#include <vector>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;
using namespace Aspose::Cells::Drawing;

int main()
{
    Aspose::Cells::Startup();

    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    U16String imageUrl = srcDir + u"image2.jpg";

    std::ifstream imageStream(imageUrl.ToUtf8(), std::ios::binary);
    if (!imageStream.is_open()) {
        std::cerr << "Failed to open image file." << std::endl;
        return -1;
    }

    imageStream.seekg(0, std::ios::end);
    std::vector<uint8_t> imageData(imageStream.tellg());
    imageStream.seekg(0, std::ios::beg);
    imageStream.read(reinterpret_cast<char*>(imageData.data()), imageData.size());
    imageStream.close();

    Aspose::Cells::Vector<uint8_t> aspImageData(imageData.data(), imageData.size());

    U16String path = srcDir + u"chord.wav";

    std::ifstream wavStream(path.ToUtf8(), std::ios::binary);
    if (!wavStream.is_open()) {
        std::cerr << "Failed to open WAV file." << std::endl;
        return -1;
    }

    wavStream.seekg(0, std::ios::end);
    std::vector<uint8_t> objectData(wavStream.tellg());
    wavStream.seekg(0, std::ios::beg);
    wavStream.read(reinterpret_cast<char*>(objectData.data()), objectData.size());
    wavStream.close();

    Aspose::Cells::Vector<uint8_t> aspObjectData(objectData.data(), objectData.size());

    int intIndex = 0;

    Workbook workbook;
    Worksheet sheet = workbook.GetWorksheets().Get(0);

    sheet.GetOleObjects().Add(14, 3, 200.0, 220.0, aspImageData);
    workbook.GetWorksheets().Get(0).GetOleObjects().Get(intIndex).SetFileFormatType(FileFormatType::Unknown);
    workbook.GetWorksheets().Get(0).GetOleObjects().Get(intIndex).SetObjectData(aspObjectData);
    workbook.GetWorksheets().Get(0).GetOleObjects().Get(intIndex).SetObjectSourceFullName(path);

    workbook.Save(outDir + u"testWAV.out.xlsx");

    std::cout << "Excel file saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
    return 0;
