How do you copy a folder and paste it in a directory in C++/CLI?

Question

How do you copy a folder and paste it in a directory?

Answer 1

To reuse a feature that is already developed in .NET Framework, use the “Add Reference…” command from PROJECT menu and add a reference to Microsoft.VisualBasic assembly. Then try a code like this:

using namespace Microsoft::VisualBasic::FileIO;
FileSystem::CopyDirectory( source_folder, destination_folder, UIOption::AllDialogs );

Prepare the corresponding source_folder and destination_folder strings.

Answer 2

There are several ways with System::IO

Another way with the Shell :

String^ sFrom = "E:\\Test2\\Temp";
String^ sTo = "E:\\test";
marshal_context^ context = gcnew marshal_context();
PCZZTSTR pFrom = context->marshal_as<PCZZTSTR>(sFrom + "\0");
PCZZTSTR pTo = context->marshal_as<PCZZTSTR>(sTo + "\0");
auto fos = new SHFILEOPSTRUCT();
fos->wFunc = FO_COPY;
fos->pFrom = pFrom;
fos->pTo = pTo;
fos->fFlags = FOF_ALLOWUNDO;
int nReturn = SHFileOperation(fos);
if (nReturn != 0)
{
 throw gcnew Win32Exception(nReturn);
}
delete context;

At beginning :

#include <msclr\marshal_cppstd.h>
using namespace msclr::interop;

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <shellapi.h>
#pragma comment (lib, "Shell32")
