title: #Define & lpCmdLine arguments
body: <p>Is it possible to define a string from startup arguments?</p>
  
  <p>For example, I have this code in header file:</p>
  
  <pre><code>#define MsgBox "Hello there!"
  </code></pre>
  
  <p>How to make it so that the <em>#define</em> string comes from the command line arguments?</p>
  
  <p>So if I would start my application like this: app.exe -Test! - the MsgBox would be defined as "Test!".</p>
  
  <p>Sorry if this is a bad explanation but hopefully at least some of you understood. 
  It is important to get the <em>#define MsgBox</em> from command line arguments, not from the program's entry point. All the code should be in the header file.</p>
  
  <p>To be honest with you, I haven't tried <em>anything</em> because I have no idea where to start. </p>
