title: Rich Text File display differently in a Rich Text Box in Win10 compared to Win7
body: <p>The issue is that RTF files with images are not showing when I compile on my  Win10 PC.</p>
  
  <p>Recently I changed my PC and with that I upgraded the OS to Win10 and VS to VS2017. Win10 is up to date and VS2017 tells me it has all the upgrades that it needs for C#. I have been writing and upgrading this app for more that two years on the Win 7 plus VS2015 system with no problem. I have also compiled the same app with code changes on the Win10 plus VS2017 system with no problems.</p>
  
  <p>For the help I use a rich text file which I pull into a Rich Text box. I first </p>
  
  <pre><code> private RichTextBox rtb_help;
  </code></pre>
  
  <p>then on form load I use</p>
  
  <pre><code> rtb_help.Rtf = Resources.Help;
  </code></pre>
  
  <p>This allows the people writing this file to have no knowledge of programming and just drop me the new file which I compile. This is what happened earlier this week. When I had compiled the app and pressed for help I see no pictures in the file. I found if I take the .RTF file back to my Win7 PC and resave it with Wordpad and then compile it on my Win10 system it works.</p>
  
  <p>When I diff the file from Win7 Wordpad and that from Win10 Wordpad I see the following difference around the images.</p>
  
  <pre><code>Win7 = \pard\nowidctlpar\qc\f2\fs22{\pict\wmetafile8\picw5318\pich6694\picwgoal1839\pichgoal2315 
  Win10 = \pard\nowidctlpar\qc\f2\fs22{\pict{\*\picprop}\wmetafile8\picw5318\pich6694\picwgoal1839\pichgoal2315 
  </code></pre>
  
  <p>Win10 appears to reference properties of the image with {*\picprop} from elsewhere in the file. This means a richtextbox cannot read the file properly so leaves out the images and gives no error/alert. </p>
  
  <p>I can see no setting in Wordpad to change this but maybe they are hidden and I need a special key sequence? </p>
  
  <p>How do I make the richtextbox show the images from both files correctly?</p>
