Select Range by string

Question

How I can change this feature so I select the range of characters in a word document between the characters "E" and "F", if I have; xasdasdEcdscasdcFvfvsdfv is underlined to me the range -> cdscasdc

private void Rango()
{
Word.Range rng;

Word.Document document = this.Application.ActiveDocument;

object startLocation = "E";
object endLocation = "F";

// Supply a Start and End value for the Range. 
rng = document.Range(ref startLocation, ref endLocation);

// Select the Range.
rng.Select();

}

This function will not let me pass by reference two objects of string type.......

Thanks

You need to pass the position in the document you want the range to cover, see: How to: Define and Select Ranges in Documents

I have added some example code below:

        Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();

        string document = null;
        using (OpenFileDialog dia = new OpenFileDialog())
        {
            dia.Filter = "MS Word (*.docx)|*.docx";
            if (dia.ShowDialog() == DialogResult.OK)
            {
                document = dia.FileName;
            }
        }           

        if (document != null)
        {
            Document doc = word.Documents.Open(document, ReadOnly: false, Visible: true);
            doc.Activate();
            string text = doc.Content.Text;

            int start = text.IndexOf('E') + 1;
            int end = text.IndexOf('F');
            if (start >= 0 && end >= 0 && end > start)
            {
                Range range = doc.Range(Start: start, End: end);
                range.Select();
            }
        }

Do not forget to close the document and Word etc.

Firstly thank you for your reply ...:) I compiled the code and I get two errors in the lines you have mentioned. I missing some parameter or do not I put where it should be? This is the complete code;

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;

namespace WordAddIn1 { public partial class ThisAddIn {

    private void Rango()
    {
        Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();

        string document = null;
        using (OpenFileDialog dia = new OpenFileDialog())
        {
            dia.Filter = "MS Word (*.docx)|*.docx";
            if (dia.ShowDialog() == DialogResult.OK)
            {
                document = dia.FileName;
            }
        }           

        if (document != null)
        {
            ***Document doc = word.Documents.Open(document, ReadOnly: false, Visible: true);***
            doc.Activate();
            string text = doc.Content.Text;

            int start = text.IndexOf('E') + 1;
            int end = text.IndexOf('F');
            if (start >= 0 && end >= 0 && end > start)
            {
                ***Range range = doc.Range(Start: start, End: end);***
                range.Select();
            }
        }

   }
   private void ThisAddIn_Startup(object sender, System.EventArgs e)
   {
       Rango();
   }
   private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
    {
    }

    #region VSTO generated code

}
