title: How do I use a third-party DLL file in Visual Studio C++?
body: <p>I understand that I need to use LoadLibrary(). But what other steps do I need to take in order to use a third-party DLL file?</p>
  
  <p>I simply jumped into C++ and this is the only part that I do not get (as a Java programmer). I am just looking into how I can use a <a href="https://en.wikipedia.org/wiki/Qt_%28software%29" rel="noreferrer">Qt</a> Library and tesseract-ocr, yet the process makes no sense to me and is so difficult to google.</p>
  
  <p>How do I tell the compiler of the functions that I am using? Should there be an include file from the third-party vendor?</p>
