Instead of creating such object, you may use SHFileOperation function[^] for the purpose.

Simplest solution:

C++

Scripting::IFileSystemPtr fs(__uuidof(Scripting::FileSystemObject));
fs->__DeleteFile(L"c:\\dmmm\\df\\*", _variant_t(false));

Showing a whole simplistic program:

C++

#include <objbase.h>
#include <comutil.h>
#undef GetFreeSpace
 #import <scrrun.dll> auto_rename


int main()
{
    CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED);

    try
    {
        Scripting::IFileSystemPtr fs(__uuidof(Scripting::FileSystemObject));
        fs->__DeleteFile(L"c:\\dmmm\\df\\*", _variant_t(false));
    }
    catch (const _com_error&)
    {}

    CoUninitialize();

    return 0;
}
</scrrun.dll></objbase.h>

Solution 1

You can create it by creating a COM object.

Ex.

C++

HRESULT hr;
CComPtr pDisp;
hr = pDisp.CoCreateInstance( L"Scripting.FileSystemObject" );//creates the object
ATLASSERT( SUCCEEDED(hr) );
CComDispatchDriver disDrv( pDisp );
CComVariant funcArg( LPCTSTR(_T("D:\\test.txt")) ), ret( false );
hr = disDrv.Invoke1(L"DeleteFile", &funcArg, &ret );//delete the file
ATLASSERT( SUCCEEDED(hr) );

You need to include <atlbase.h> for this <atlbase.h>
