Release Unmanaged Resources of the Workbook with C++

Aspose.Cells provides Workbook.Dispose() method to release the unmanaged resources of the Workbook object. The dispose pattern is used only for objects that access unmanaged resources, such as file and pipe handles, registry handles, wait handles or pointers to blocks of unmanaged memory. This is because the garbage collector is very efficient at reclaiming unused managed objects, but it is unable to reclaim unmanaged objects.

Workbook object now implements the IDisposable interface which has a single method Dispose(). You can either directly call the Workbook.Dispose() method or you can use the Using statement to call this method automatically.

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

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

    // Create workbook object
    Workbook wb1;

    // Call Dispose method
    wb1.Dispose();

    // Call Dispose method via RAII (Resource Acquisition Is Initialization)
    {
        Workbook wb2;
        // Any other code goes here
    } // wb2 is automatically disposed when it goes out of scope

    Aspose::Cells::Cleanup();
}
