  I dont see any error in your code for object initialization.

  I would suggest you the following to change;

  1.When Application is set to invisible then document should be also invisible.

  ( i.e in your case for doc1, Object visible=false; )

  2. I dont see any usage of this code;

  doc1.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);

  Because, you are getting error count from the Proofreading object. Better would be comment this code.

  3. Before quitting the application it is always recommended to close the all open documents;

  object ObjFalse=false;

  object ObjMissing=Missing.Value;

  doc1.Close(ref ObjFalse, ref ObjMissing, ref ObjMissing);

  you have to download the Introp Assamblies. include the reference of word object library after download and installation.

  Hi OmerKamal, the correction didn't stop the exception. It is in the this statement:

  if (textBox1.Text.Length > 0) The debugger has highlighted this statement with the error:

  "Object reference not set to an instant of object." which I don't quite understand what it means.

  Thanks for helping jbattat

  With using this example, how could I add other text boxes and have the spell checker check it

  Hi, I did use that link and downloaded the the Word object library. while it compiles but I received an exception "object reference not set to an instance of object" in the if statement. It is for the using the Microsoft Word spell check. this is the code:

  private void spellToolStripMenuItem_Click(object sender, EventArgs e)

  {

  Word.Application app = new Word.Application();

  int errors = 0;

  if (textBox1.Text.Length > 0)

  {

  app.Visible = false;

  object template = Missing.Value;

  object newTemplate = Missing.Value;

  object documentType = Missing.Value;

  object visible = true;

  Word._Document doc1 = app.Documents.Add(ref template, ref newTemplate, ref documentType, ref visible);

  doc1.Words.First.InsertBefore(textBox1.Text);

  Word.ProofreadingErrors spellErrorsColl = doc1.SpellingErrors;

  errors = spellErrorsColl.Count;

  object optional = Missing.Value;

  doc1.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);

  label1.Text = errors + " errors corrected ";

  object first = 0;

  object last = doc1.Characters.Count - 1;

  textBox1.Text = doc1.Range(ref first, ref last).Text;

  }

  object saveChanges = false;

  object originalFormat = Missing.Value;

  object routeDocument = Missing.Value;

  app.Quit(ref saveChanges, ref originalFormat, ref routeDocument);

  }

  Can you assist
