Inserting Text into Word

Question

I have tried everything but I cannot figure this out. I need to insert text into an already open Word Document.
I am using C#. This is an add-in, so Word is already open. If I use the new Document method like all the examples show it brings up fresh document and won't work (obviously) . What is the correct syntax for inserting text using C# if the document is already open. Thanks.

That didn't work for me. I need the text to be inserted when I click the button. Here is the code I have. namespace SignatureAddin { using System; using System.Diagnostics; using System.Drawing; using System.IO; using System.Reflection; using System.Security.Cryptography; using System.Security.Cryptography.X509Certificates; using System.Security.Cryptography.Xml; using System.Text; using System.Windows.Forms; using System.Xml; using Microsoft.Office.Tools.Word; using Microsoft.Office.Tools.Word.Extensions; using Extensibility; using Microsoft.Office.Core; using stdole; using XmlDataObject = System.Security.Cryptography.Xml.

Hello Cory you can simply use the function this.Application.Selection.TypeText(This is my new Text) to type a text. Here is a short listing for an Addin that writes Hello every time a new document opens: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Xml.Linq; using Word = Microsoft.Office.Interop.Word; using Office = Microsoft.Office.Core; using Microsoft.Office.Tools.Word; using Microsoft.Office.Tools.Word.Extensions; using Microsoft.Office.Interop.Word; namespace WordAddIn1 { public partial class ThisAddIn { private void ThisAddIn_Startup(object sender System.EventArgs e) { // use this method at any place to insert text this.Application.Selection.TypeText(Hello); } private void ThisAddIn_Shutdown(object sender System.EventArgs e) { } #region VSTO generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InternalStartup() { this.Startup += new System.EventHandler(ThisAddIn_Startup); this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown); } #endregion } }
