title: Compiler Can't Find My Header?
body: <p>Despite hash-including it, my project cannot seem to find its header file. I have included a screenshot because I think it's the most effective way to showcase my problem:</p>
  
  <p><strong>ERROR MESSAGE</strong></p>
  
  <p>1>c:\users\wood\desktop\old programs\locker.cpp(2): fatal error C1083: Cannot open include file: 'Locker.h': No such file or directory</p>
  
  <p><img src="https://i.stack.imgur.com/LyTrt.png" alt="As you can see, I have included Locker.h at the top of the file, and it is also listed under &#39;Header Files&#39; on the left."></p>
  
  <p>Any ideas as to what's gone wrong? I've tried: 1) Cleaning the project and rebuilding it. 2) Creating a brand new, identical project. </p>
  
  <p>Thanks!</p>
