title: C# Word Interop - Spell Checking in a Certain Language
body: <p>For a customer of mine I need to force the spell checking in a certain language.</p>
  
  <p>I have explored the MSDN documentation and found that when calling the <code>CheckSpelling()</code> method in the active document, it will invoke the spelling check. This method has parameters for custom dictionaries.</p>
  
  <p>My problem is that I can't find anything about those dictionaries or how to use them.</p>
  
  <p>Also there is still the possibility that there is of course another way to do this.</p>
  
  <p>Can anybody boost me in the right direction?</p>
