Saving File to Response Object with C++

Aspose.Cells makes it possible to manipulate files. This article explains the various ways in which files can be saved to a response object.

Saving File to Response Object

It is also possible to generate a file dynamically and send it directly to a client browser. In order to do so, use a special overloaded version of the Save method that accepts the following parameters:

• HttpResponse object.
• File name.
• ContentDisposition, the content-disposition type of the output file.
• SaveOptions, the file format type.

The ContentDisposition enumeration determines whether the file being sent to the browser provides the option to open by itself directly in the browser or in an application associated with .xls/.xlsx or another extension.

The enumeration contains the following pre-defined save types:

Type	Description
Attachment	Sends the spreadsheet to the browser and opens in an application as an attachment associated with .xls/.xlsx or other extensions
Inline	Sends the document to the browser and presents an option to save the spreadsheet to disk or open inside the browser

XLS Files

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

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

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Create a new workbook
    Workbook workbook;

    // Save in Excel2003 XLS format
    U16String outputPath = outDir + u"output.xls";
    XlsSaveOptions saveOptions;
    workbook.Save(outputPath, saveOptions);

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

XLSX Files

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

using namespace Aspose::Cells;

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

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Path of output excel file
    U16String outputFilePath = outDir + u"output.xlsx";

    // Create workbook
    Workbook workbook;

    // Save in Xlsx format
    OoxmlSaveOptions saveOptions;
    workbook.Save(outputFilePath, saveOptions);

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

PDF Files

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

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

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Path of output PDF file
    U16String outputPdf = outDir + u"output.pdf";

    // Creating a Workbook object
    Workbook workbook;

    // Save in Pdf format
    PdfSaveOptions saveOptions;
    workbook.Save(outputPdf, saveOptions);

    Aspose::Cells::Cleanup();
}

Note

Due to the object “System.Web.HttpResponse” which is not included in .NET5 and .Netstandard, So this function does not exist in Aspose.Cells .NET5 and .Netstandard version, you can refer to the following code to save the file to the stream, then do operation to the stream.

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

using namespace Aspose::Cells;

int main()
{
    Startup();

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

    U16String inputFilePath = srcDir + u"Book1.xlsx";
    Workbook workbook(inputFilePath);

    // Save workbook to memory stream with explicit FileFormatType
    Vector<uint8_t> data = workbook.SaveToStream();

    std::cout << "File size: " << data.GetLength() << std::endl;

    Cleanup();

    return 0;
}
