title: Convert int to LPCWSTR by using wsprintf
body: <p>As the following code:</p>
  
  <pre><code>int a = 16;
  wchar_t *buffer = {0};
  wsprintf(buffer,L"%d", a);
  
  MessageBox(NULL, buffer, buffer, MB_OK);
  </code></pre>
  
  <p>I want to covert int to LPCWSTR in order to put MessageBox.
  I really newbie in using wsprintf. Any one can help me explain clearly for me using this function??? (Please, I also read MSDN but still dont't clear)</p>
  
  <p>I mean, I want to print "16" in MessageBox</p>
