Well, you can open a word doc into a richtextbox control using a cut and paste operation from an open instance of the document, or you can open the file into the user's installed copy of word. To open the file into a richtextbox, this works: // locals object noSave = false ; object missingVal = System.Reflection. Missing .Value; object fileName = @"C:\folder\subc\clover.doc" ; // instance word app, doc Microsoft.Office.Interop.Word. _Application wordApp = new Microsoft.Office.Interop.Word. Application (); wordApp.Visible = false ; // hides MS Word Microsoft.Office.Interop.Word. _Document wordDoc; // open the document wordDoc = wordApp.Documents.Open( ref fileName, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal, ref missingVal); // select the entire document and copy it wordDoc.Select(); wordApp.Selection.Copy(); // clear the target richtextbox control richTextBox1.Text = string .Empty; // paste the word doc into the richtextbox control // - this may not come out perfect; table formatting for example may not // survive the operation intact or hyperlinks might be altered (e.g., an // email address will show up with mailto added...) richTextBox1.Paste(); // clean up wordDoc.Close( ref noSave, ref missingVal, ref missingVal); wordApp.Quit( ref noSave, ref missingVal, ref missingVal); If you just want to open the document from the application; this will suffice: System.Diagnostics. Process .Start( @"C:\somefolder\clover.doc" ); If you want to open a PDF into an application, I would use the acrobat reader activeX control; with that dropped into a form you can load a PDF using something like this (you should find in the program files/adobe/activeX folder or you can download it if you don't have it): axAcroPDF1.LoadFile( @"C:\Temp\NMEA20ReferencManual1.pdf" ); Or, if you just want to open it using the application, this will suffice: System.Diagnostics. Process .Start( @"C:\Temp\NMEA20ReferencManual1.pdf" ); You might look at iTextSharp and see if you can do anything with that.
