Hi All,

I am creating a class library project for VC++ in VS 2005. On
compilation, the following error is returned

error C2664: 'LookupAccountNameW' : cannot convert parameter 1 from
'char *' to 'LPCWSTR'
the line of concern is :

if ( ! LookupAccountName( argv[1], argv[2], userSid, &sidSize, refDom,
&domSize, &sidUse ) )
        err( "LAN()", gle, false );

I think the problem lies in the fact that the .h file has a main
function which is as follows

int main( int argc, char *argv[] )
{
    if ( argc != 3 )
    {
        puts( "Usage: lsa_lear <system name> <account name>" );
        puts( "Enumerates privileges for the named account on the named
machine." );
        puts( "<system name> is the machine where the lookup will
execute." );
        puts( "<account name> is the account to examine, e.g. \"FOO\\felixk
\" or \"Administrators\"." );
        return 1;
    }

    // open the policy object on the target computer

    static SECURITY_QUALITY_OF_SERVICE sqos = { sizeof
SECURITY_QUALITY_OF_SERVICE, SecurityImpersonation,
SECURITY_DYNAMIC_TRACKING, FALSE };
    static LSA_OBJECT_ATTRIBUTES lsaOA = { sizeof LSA_OBJECT_ATTRIBUTES,
NULL, NULL, 0, NULL, &sqos };
    NTSTATUS nts;
    LSA_HANDLE polHandle;
    LsaUnicodeString systemName;

    systemName = argv[1];

    nts = LsaOpenPolicy( systemName, &lsaOA, GENERIC_READ |
GENERIC_EXECUTE, &polHandle );
    err( "LOP()", nts );

    // translate the account name to a RID plus associated domain SID

    SID *userSid;
    char refDom[MAX_PATH];
    SID_NAME_USE sidUse;
    DWORD sidSize, domSize;
    const char *acctTypeString;

    userSid = (SID *) malloc( MAX_PATH );
    sidSize = domSize = MAX_PATH;

    if ( ! LookupAccountName( argv[1], argv[2], userSid, &sidSize,
refDom, &domSize, &sidUse ) )
        err( "LAN()", gle, false );

    acctTypeString = NULL;
    switch ( sidUse )
    {
        case SidTypeAlias:
        case SidTypeUser:
        case SidTypeGroup:
        case SidTypeWellKnownGroup:
            break;
        case SidTypeDomain:
            if ( acctTypeString == NULL )
                acctTypeString = " domain";
            // fall-through
        case SidTypeInvalid:
            if ( acctTypeString == NULL )
                acctTypeString = "n invalid";
            // fall-through
        case SidTypeUnknown:
            if ( acctTypeString == NULL )
                acctTypeString = "n unknown";
            // fall-through
        case SidTypeDeletedAccount:
            if ( acctTypeString == NULL )
                acctTypeString = " deleted";
            printf( "Don't know how to handle a%s account.\n",
acctTypeString );
            return 1;
    }

    LsaUnicodeString *userRights;
    ULONG count;

    userRights = NULL;
    count = 0;
    nts = LsaEnumerateAccountRights( polHandle, userSid,
(LSA_UNICODE_STRING **) &userRights, &count );
    err( "LEAR()", nts );

    DWORD i;
    char *p;

    printf( "%d privileges for user \"%s\" in domain \"%s\":\n", count,
argv[2], refDom );
    for ( i = 0; i < count; ++ i )
    {
        p = (char *) userRights[i]; // must free() later
        printf( "priv %u: %s\n", i, p );
        free( p );
    }

    LsaClose( polHandle );
    free( userSid );

    return 0;
}

Could someone assist me in getting rid of this problem.

Thanks
