Embed Word spellcheck in a Windows Form application

Question

I have a Windows Form Application that I would like to use for spell checking. Everyone has Office 2007 installed, so I should not have problems, but I have problems with its full operation.

Here is what I have:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Word = Microsoft.Office.Interop.Word;
using System.Reflection;

namespace Refraction.Spelling
{
    public static class SpellCheckers
    {
        public static string CheckSpelling(string text)
        {
            Word.Application app = new Word.Application();
 object nullobj = Missing.Value;
                object template = Missing.Value;
                object newTemplate = Missing.Value;
                object documentType = Missing.Value;
                object visible = true;
                object optional = Missing.Value;
            object savechanges = false;
            Word._Document doc = app.Documents.Add(ref template, ref newTemplate, ref documentType, ref visible);

        doc.Words.First.InsertBefore(text);
        Word.ProofreadingErrors errors = doc.SpellingErrors;

        var ecount = errors.Count;
        doc.CheckSpelling(ref optional, ref optional, ref optional, ref optional, 
            ref optional, ref optional, ref optional, ref optional, ref optional, 
            ref optional, ref optional, ref optional);
        object first = 0;
        object last = doc.Characters.Count - 1;
        var results = doc.Range(ref first, ref last).Text;
        doc.Close(ref savechanges, ref nullobj, ref nullobj);
        app.Quit(ref savechanges, ref nullobj, ref nullobj);

        return results;
    }
}

}

I use it like this:

memDirectionsToAddress.Text = SpellCheckers.CheckSpelling(memDirectionsToAddress.Text);

Now it successfully displays the SpellCheck dialog from Word and detects any misspelled words , but I cannot get it to make corrections to the WinForm application .

In addition, it leaves this Word Doc “shell” open with the corrected text. How can I not show it or at least remove it?

Two things:

• Firstly, although the "shell" closes it, it blinks every time. Any solutions what?
• -, TOP, ?
