I have tested my code in VB.Net and it is working fi9 but now I have to c# and having errors in my code

 {

  try
  {
            object objWord;
            object objTempDoc;
   IDataObject iData;

   if (TextBox1.Text == "")
   {
    return;
   }

            objWord = new Microsoft.Office.Interop.Word.Application();
   objTempDoc = objWord.Documents.Add();
   objWord.Visible = false;

   objWord.WindowState = 0;
   objWord.Top = - 3000;

   Clipboard.SetDataObject(TextBox1.Text);

   objTempDoc.Content.Paste();
   objTempDoc.Activate();
   if (blnSpellOnly)
   {
    objTempDoc.CheckSpelling();
   }
   else
   {
    objTempDoc.CheckGrammar();
   }
   objTempDoc.Content.Copy();
   iData = Clipboard.GetDataObject();
   if (iData.GetDataPresent(DataFormats.Text))
   {
    TextBox1.Text = System.Convert.ToString(iData.GetData(DataFormats.Text, System.Convert.ToBoolean(null)));
   }
   objTempDoc.Saved = true;
   objTempDoc.Close();

   objWord.Quit();

   MessageBox.Show("The spelling check is complete.", "Spell Checker", MessageBoxButtons.OK, MessageBoxIcon.Information);

  }
  catch (System.Runtime.InteropServices.COMException)
  {
   MessageBox.Show("Microsoft Word must be installed for Spell/Grammar Check " + "to run.", "Spell Checker");

  }
  catch (Exception)
  {
   MessageBox.Show("An error has occurred.", "Spell Checker");

  }

 }

Answer 1

Is there any reason you're not using aspell.net? Office interop is, well, a little fiddly.

Answer 2

Object doestnot contain definition of Document. This is error which I am getting on building. I have include Reference of Microsoft.Office.Interop.Word successfully in c#

Answer 3

C# does not support late binding. You must declare objWord as Microsoft.Office.Interop.Word.Application instead of object. Dito for objTempDoc (whatever type Documents.Add returns).

Answer 4

Hi danbystrom, I tried your suggestion although it is good but didn't work for me. Now it is throwing new exception that

objTempDoc = objWord.Documents.Add();

Exception : No overload for method Add takes '0' arguments.

Any suggestion ?
