word using C#

Hi mackie, first regarding this line:

//  Just to kill WINWORD.EXE if it is running
killprocess("winword");

Don't do that, I believe the reason why you are using it because you noticed that after you run your application a MS Word is still running. This occurs because of the inappropriate closing of that application, you see when working with word automation in C# you need to be careful about correctly releasing those COM resources, for example something link the following should work:

aDoc.Close();
wordApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(wordApp);

But if you want to avoid that hassle with COM interface I would recommend you to try out this C# component for Word documents. You see you can easily read, modify and then write your DOCX files in C# with it.

Also you even have a direct solution for your requirement, instead of using a find and replace approach you should take a look at a mail merging process in C#.

And last thing you even have a direct API for printing your Word documents in C#.

I've assumed that you're using .NET 4.0 or later (VS 2010 onwards) and you'll first need to add a reference (under the COM tab) to the Microsoft Word 12.0 (or later) object library:

using System.IO;
using Word = Microsoft.Office.Interop.Word;


Word.Application wordApp = new Word.Application();
            wordApp.Visible = false;
            Word.Document doc = wordApp.Documents.Add();
            string dirPath = @"C:\";



//You might want to add some more code here for inserting pages text adding header and footer



doc.Close();
            wordApp.Quit();
            MessageBox.Show("Word file created");

}
