title: How to insert data into "placeholders" of a Word document?
body: <p>I've read this <a href="https://msdn.microsoft.com/en-us/library/cc442946.aspx?f=255&amp;MSPPError=-2147217396" rel="nofollow noreferrer">article</a> and I am amazed by opportunities of VSTO. It is really cool. Now I want to create some user controls(WPF) and insert data to a Word document at the specific places like that:
  <a href="https://i.stack.imgur.com/2fAM3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2fAM3.png" alt="enter image description here"></a></p>
  
  <p>I will have three WPF <code>TextBox</code>'es corresponding to <code>placeHolder_*</code> and a <code>button</code> which will read data from <code>TextBox</code>'es and insert text into placeholders. How to do it?(Couldn't find any info about it)</p>
  
  <p>Any help such as example, tutorials which will be greatly appreciated!:) </p>
