title: Convert 4 bytes into DWORD in C++
body: <p>I have a pointer to byte, which actually points to array of 4 bytes (created by RegQueryValueEx).<br>
  I want to convert these 4 bytes into one DWORD.<br>
  Although it seems to be very simple and surely there is an existing method does it, I didn't succeed to find it.</p>
  
  <p>Alternatively: The registered value is a TimeStamp. Is there a method which convert from 4-bytes array represents TimeStamp into a string?</p>
