Hi Make sure you add a reference to Microsoft.Office.Interop.Word in your project in order for this to work. I used the Office 2007 Libraries for this. using System; using System.Linq; using System.Windows.Forms; using Microsoft.Office.Interop.Word; using System.IO; namespace WordControls { public partial class DocBrowser : UserControl { private System.Windows.Forms.WebBrowser webBrowser1; delegate void ConvertDocumentDelegate( string fileName); public DocBrowser() { InitializeComponent(); // Create the webBrowser control on the UserControl. // This code was moved from the designer for cut and paste // ease. webBrowser1 = new System.Windows.Forms.WebBrowser(); webBrowser1.Dock = System.Windows.Forms.DockStyle.Fill; webBrowser1.Location = new System.Drawing.Point(0 0); webBrowser1.MinimumSize = new System.Drawing.Size(20 20); webBrowser1.Name = webBrowser1 ; webBrowser1.Size = new System.Drawing.Size(532 514); webBrowser1.TabIndex = 0; Controls.Add(webBrowser1); // set up an event handler to delete our temp file when we're done with it. webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted; } string tempFileName = null ; public void LoadDocument( string fileName) { // Call ConvertDocument asynchronously. ConvertDocumentDelegate del = new ConvertDocumentDelegate(ConvertDocument); // Call DocumentConversionComplete when the method has completed. del.BeginInvoke(fileName DocumentConversionComplete null ); } void ConvertDocument( string fileName) { object m = System.Reflection.Missing.Value; object oldFileName = ( object )fileName; object readOnly = ( object ) false ; ApplicationClass ac = null ; try { // First create a new Microsoft.Office.Interop.Word.ApplicationClass. ac = new ApplicationClass(); // Now we open the document. Document doc = ac.Documents.Open( ref oldFileName ref m ref readOnly ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m); // Create a temp file to save the HTML file to. tempFileName = GetTempFile( html ); // Cast these items to object. The methods we're calling // only take object types in their method parameters. object newFileName = ( object )tempFileName; // We will be saving this file as HTML format. object fileType = ( object )WdSaveFormat.wdFormatHTML; // Save the file. doc.SaveAs( ref newFileName ref fileType ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m ref m); } finally { // Make sure we close the application class. if (ac != null ) ac.Quit( ref readOnly ref m ref m); } } void DocumentConversionComplete(IAsyncResult result) { // navigate to our temp file. webBrowser1.Navigate(tempFileName); } void webBrowser1_DocumentCompleted( object sender WebBrowserDocumentCompletedEventArgs e) { if (tempFileName != string .Empty) { // delete the temp file we created. File.Delete(tempFileName); // set the tempFileName to an empty string. tempFileName = string .Empty; } } string GetTempFile( string extension) { // Uses the Combine GetTempPath ChangeExtension // and GetRandomFile methods of Path to // create a temp file of the extension we're looking for. return Path.Combine(Path.GetTempPath() Path.ChangeExtension(Path.GetRandomFileName() extension)); } } } Here's a simple form I built with the control. The button's event handler simply calls LoadDocument on the DocBrowser control which is the main portion of the screen.
