Understanding the recursion.

Here is the golden rule to understand the recursion:
"In order to understand recursion one must first understand recursion."

Microsoft Office Word automation in C# - How to add table to the document?

The following C# code will create a new document, add a table to it and ask the user to save it. Document will look like this:



The following code will add a table in word and then ask the user to provide a filename to save the document:
        Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.ApplicationClass();
        app.Visible = false;

        object start = 0;
        object end = 0;
        object oNull = System.Reflection.Missing.Value;

        Document doc = new DocumentClass();
        doc = app.Documents.Add(ref oNull, ref oNull, ref oNull, ref oNull);

        Table tbl = doc.Tables.Add(doc.Range(ref start, ref end), 10, 2, ref oNull, ref oNull);
        Random rnd = new Random();
        for (int i = 0; i < 10; i++)
        {
           tbl.Rows[i + 1].Cells[1].Range.Text = "Run# :" + ((int)i + 1).ToString();
           tbl.Rows[i + 1].Cells[2].Range.Text = "Value :" + rnd.Next(0, 2000).ToString();
        }

        object oFalse = false;
        app.Visible = true;
        try
        {
           doc.Save();
        }
        catch (Exception ex)
        {
           if (ex.Message.ToLower().IndexOf("command failed") == -1)
           {
             throw ex;
           }
        }
        app.Quit(ref oFalse, ref oFalse, ref oFalse);

What we done is to create a new document, a new table, and fill the table with random values.
Seems very easy but not quite sure how well document :).
