title: Cannot convert parameter from 'const char[20]' to 'LPCWSTR'
body: <p>When compiling this code:</p>
  
  <pre><code>#include &lt;windows.h&gt;
  
  int WINAPI WinMain(HINSTANCE hInsance,HINSTANCE hPrevInstance,PSTR cmdLine,int showCmd){
      MessageBox(0,"First Win32 Program","Window Tittle",MB_OK);
      }
  </code></pre>
  
  <p>I get the compiler error:</p>
  
  <blockquote>
    <p>Error C2664: 'MessageBoxW': cannot convert parameter 2 from 'const char [20]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast</p>
  </blockquote>
  
  <p>What am I doing wrong?</p>
