i have a problem on these codes trying to write official letters. My requirements were letter template & content that can be changed any time and application will help to get only inputs like sent to name, organization name, date, etc. and after that when user presses finish button, the letter should be ready for print out along with predefined content & inputs.

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Word = Microsoft.Office.Interop.Word;//<- this is what I am talking about
namespace generateletter
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
// create offer letter
try
{
// Just to kill WINWORD.EXE if it is running
killprocess("winword");
// copy letter format to temp.doc
File.Copy("C:\\OfferLetter.doc", "c:\\temp.doc", true);
// create missing object
object missing = Missing.Value;
// create Word application object
Word.Application wordApp = new Word.ApplicationClass();
// create Word document object
Word.Document aDoc = null;
// create & define filename object with temp.doc
object filename = "c:\\temp.doc";
// if temp.doc available
if (File.Exists((string)filename))
{
object readOnly = false;
object isVisible = false;
// make visible Word application
wordApp.Visible = false;
// open Word document named temp.doc
aDoc = wordApp.Documents.Open(ref filename, ref missing,
ref readOnly, ref missing,ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing,
ref missing,ref isVisible, ref missing, ref missing,
ref missing, ref missing);
aDoc.Activate();
// Call FindAndReplace()function for each change
this.FindAndReplace(wordApp, "", dtpDate.Text);
this.FindAndReplace(wordApp, "", txName.Text.Trim());
this.FindAndReplace(wordApp, "",
txtSubject.Text.Trim());
// save temp.doc after modified
aDoc.Save();
}
else
MessageBox.Show("File does not exist.",
"No File", MessageBoxButtons.OK,
MessageBoxIcon.Information);
killprocess("winword");
}
catch (Exception)
{
MessageBox.Show("Error in process.", "Internal Error",
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}

hi,
check your project web.config to make sure that there is no double entry for assembly Microsoft.Office.Interop.Word
hope this will help you.
