title: Opening Powerpoint Presentation in SlideShow Mode
body: <p>I want to open a powerpoint directly in a slideshow mode. The code I am trying to use is this:</p>
  
  <pre><code>Process.Start("powerpnt", "/s "str_Presfileopen)
  </code></pre>
  
  <p>'str_Presfileopen is a string containing the path of the file</p>
  
  <p>But this doesn't work. It says that Comma')' or a valid expression continuation expected.</p>
  
  <p>I tried to use the process start info:</p>
  
  <pre><code>Dim Presfileopen As New ProcessStartInfo()
  Process.Start("powerpnt", "/s " Presfileopen)
  </code></pre>
  
  <p>But this doesn't work as well. Here too it says that Comma')' or a valid expression continuation expected.</p>
  
  <p>What the hell am I doing wrong? 
  As a test I wrote in the direct code and this works but I can't do it like this because I need the user to select the file from a list.
  The code that works:</p>
  
  <pre><code>Process.Start("powerpnt", "/s ""a.pptx")
  </code></pre>
