[C++] casting da char * a PWSTR *

[gianvituzzi]

Salve,

ho un problema con questo codice:

http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx

#include <iostream>
#include <string>
#include <cstdlib>
#include <shlobj.h>

int main()
{
	LPSTR fullpath;
	HRESULT res = SHGetKnownFolderPath(FOLDERID_LocalAppData, 0, 0, fullpath);
}

ma ottengo questo:

'SHGetKnownFolderPath' : cannot convert parameter 4 from 'char *' to 'PWSTR *'

come devo fare il casting?

grazie
