open and edit word document through form application

use SaveAs instead of Save like this

Use document.saveAs option.

doc.SaveAs("MyFile.doc", ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);

Iftikar, If i want to save changes in another document, not in my current document, then what i will have to do..

Hey iftikar, thanks a lot..it's working.. :)... but now i have to understand the code...

Muralidhar, i don't have office.dll. and may i know from where i will get office.dll

Muralidhara,  how can i launch word in my application.

Error    1    The type or namespace name 'Office' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)    C:\Users\User\Downloads\ShivProject\ShivProject\EditDocument.cs    3    24    ShivProject


Iftikar, this error i am getting.

If you call,  System.Diagnostics.Process.Start(textBox1.Text);
it will open in a separate process in that you can't do Find & replace. 

Instead of that, launch word in your application, do the find & replace.

The code looks something similar to this.

It will write some text into the word document and you can try for find & replace here.

      private void button1_Click(object sender, EventArgs e)
        {
            object missing = System.Reflection.Missing.Value;
            object Visible=true;
            object start1 = 0;
            object end1 = 0;
 
            ApplicationClass WordApp = new ApplicationClass();
            Document adoc = WordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing);
            Range rng = adoc.Range(ref start1, ref missing);
 
            try
            {              
                rng.Font.Name = "Georgia";
                rng.InsertAfter("Hello World!");
                object filename = "YOUR DOCUMENT PATH";
                adoc.SaveAs(ref filename, ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
                WordApp.Visible = true;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }        
        }
