title: Visual C++ can't find "Windows types" like PVOID, DWORD, ULONG, etc
body: <p>Windows can't seem to find any of these types, and I'm completely at a loss for what to do. The things I've found on MSDN seem to suggest that they're included by default, but they haven't worked in Native programs or CLR programs.</p>
  
  <p>The specific errors I'm getting are:</p>
  
  <p><code>"&lt;Project Name&gt;.cpp(10): error C2065: 'PVOID' : undeclared identifier</code></p>
  
  <p><code>"&lt;Project Name&gt;.cpp(10): error C2146: syntax error : missing ';' before identifier 'varname'</code></p>
  
  <p><code>"&lt;Project Name&gt;.cpp(10): error C2065: 'varname' : undeclared identifier</code></p>
  
  <p>How can I make Visual C++ recognize these types?</p>
