Create a new windows application project and add a button to it.

On click of that button, we will open a document and first add a heading 1 programmatically and then insert a table of content programmatically and update it

Than we will add reference to (Word 10.0 or 11.0 object library) within COM tab of Add reference dialog box.

After adding reference, we’ll add this directive using Microsoft.Office.Interop.Word than we’ll put the following code in the button click event handler

// For optional parameters create a missing object

object missing = System.Reflection.Missing.Value;

// Create an object for filename which is the file to be opened

object fileName = @”C:\MySecond.doc”;

// Create an object of application class

ApplicationClass WordApp = new ApplicationClass();

// open the document specified in the fileName variable

Document adoc = WordApp.Documents.Open(ref fileName, ref missing, ref missing, ref missing, ref missing,

ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,

ref missing, ref missing, ref missing);

Range myRange = adoc.Range(ref missing, ref missing);

myRange.InsertAfter(“Hello Mickey Mouse GG “);

object oStyleName = “Heading 1”;

myRange.set_Style(ref oStyleName);

object start=WordApp.ActiveDocument.Content.End – 1;

Range rangeForTOC = adoc.Range(ref start, ref missing);

TableOfContents toc=adoc.TablesOfContents.Add(rangeForTOC, ref missing, ref missing, ref missing, ref missing, ref missing,ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

toc.Update();

Range rngTOC = toc.Range;

rngTOC.Font.Size = 10;

rngTOC.Font.Name = “Georgia“;

WordApp.Visible = true;

Bye…
