title: How to display PDF or Word's DOC/DOCX inside WinForms window?
body: <p>I'm wondering what's the best option to display a pdf/doc document inside form in my c# winforms app.</p>
  
  <p>This control should only allow do display preview. Edtiting documents should be forbidden.</p>
  
  <p>I'm looking for free solution.</p>
  
  <p>The best option would be to attach a few separate *.dlls to solution but it's not a requirement. </p>
