DsoFramer - Microsoft.Office.Interop.PowerPoint : DOTNET
This is a discussion on DsoFramer - Microsoft.Office.Interop.PowerPoint within the DOTNET forums in Framework and Interface Programming category; Hi, I try to control a PowerPoint Slideshow with c#. I have a dsoFramer Control (axFramerControl) and can load and view a powerpoint presentation within my form. When I try to control the presentation using Microsoft.Office.Interop.PowerPoint I get a Cast Exception. Here is some code to understand my problem. //Load presentation into control axFramerControl.Open(loc); //try to get the presentation for controling. Produce a Invalid CastException. Microsoft.Office.Interop.PowerPoint.PresentationClass myPres = (Microsoft.Office.Interop.PowerPoint.PresentationClass)axFramerControl.ActiveDocument; When I try this with word I have no Problems Microsoft.Office.Interop.Word.DocumentClass myDoc = (Microsoft.Office.Interop.Word.DocumentClass)axFramerControl.ActiveDocument; I hope there is someone who can tell how to get the presentation.

| DsoFramer - Microsoft.Office.Interop.PowerPoint Hi I try to control a powerpoint slide show inside a dsoFramer Control (axFramerControl). When I press the F5 key, the slides are shown inside my control. When I try to automate it, the slides are shown in full screen, outside my control. Here is a part of my code: Object refmissing = System.Reflection.Missing.Value; object loc = strFileName; //open ppt in control - works axFramerControl.Open(loc, true, refmissing, refmissing, refmissing); //get reference to ppt inside control Microsoft.Office.Interop.PowerPoint._Presentation myPres = (Microsoft.Office.Interop.PowerPoint.Presentation)axFramerControl.ActiveDocument; //start presentation - does not worg (fullscreen insted of control) myPres.SlideShowSettings.Run(); I hope someone can help me.
