Re: where is the mistake here?

TCHAR buffer [16384];
DWORD bufferSize = sizeof(buffer)/sizeof(buffer[0]);
BOOL bRes = InternetGetCookie(("http://www.codeproject.com"), NULL,
(LPWSTR)buffer, &bufferSize);
DWORD ret;
if(bRes==FALSE)
{
    ret = ::GetLastError();
                CString str;
    str.Format(_T("%d"),ret);
    MessageBox(NULL,str,NULL,MB_OK);
    MessageBox(NULL,_T("no items1"),NULL,MB_OK);
    if (ret == ERROR_NO_MORE_ITEMS)
    MessageBox(NULL,_T("no items"),NULL,MB_OK);
    else if(ret == ERROR_INSUFFICIENT_BUFFER)
    MessageBox(NULL,_T("insufficient buffer"),NULL,MB_OK);
    else if(ret == ERROR_INVALID_PARAMETER)
    MessageBox(NULL,_T("invalid parameters"),NULL,MB_OK);
}
else
{

    MessageBox(NULL,buffer,NULL,MB_OK);
}

This code is displaying garbage value for buffer.But I need the cookie
value.what to do?
