    copied!<p>I want to play some <code>ppt</code> files in a continuous loop, but when I open a new File after the first has reached its last slide, a new PowerPoint window opens and starts the Slide. How can I solve that problem?</p> <pre><code> public Microsoft.Office.Interop.PowerPoint.SlideShowWindow startppt(string pptDatei) { WatchingLabel.Text = "Präsentation läuft..."; started = true; ende = false; objPres = ppApp.Presentations.Open(pptDatei, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoTrue); objPres.SlideShowSettings.ShowWithAnimation = Microsoft.Office.Core.MsoTriState.msoTrue; presWin = objPres.SlideShowSettings.Run(); return presWin; } private void timer1_Tick(object sender, EventArgs e) { WatchingLabel.Text = "Watching..."; if (System.IO.Directory.Exists(ordner)) { pptDatei.Clear(); pptDatei.AddRange(System.IO.Directory.GetFiles(ordner, "*.ppt")); if (started == true &amp;&amp; presWin.View.State == Microsoft.Office.Interop.PowerPoint.PpSlideShowState.ppSlideShowDone) { objPres.Close(); ende = true; started = false; } if (pptDatei.Count &gt; 0 &amp;&amp; ende &amp;&amp; started == false) { if (index &lt; pptDatei.Count) { startppt(pptDatei[index]); index += 1; } else { index = 0; } } else if (pptDatei.Count &gt; 0 &amp;&amp; ende == false &amp;&amp; started == true) { presWin.View.Next(); } } } public void ppApp_PresentationClose(Microsoft.Office.Interop.PowerPoint.Presentation Pres) { pptDatei = new List&lt;string&gt;(); started = false; ende = true; WatchingLabel.Text = "Präsentation beenden..."; } public void ppApp_SlideShowEnd(Microsoft.Office.Interop.PowerPoint.Presentation Pres) { ende = true; started = false; } </code></pre>
