strBuilder.Append("<td style='width:100px;color:red'>India</td>".ToString());
strBuilder.Append("</tr>".ToString());
strBuilder.Append("</table>".ToString());
// string strPath = Request.PhysicalApplicationPath + "\\document\\Test.doc";
string strPath = filename;
//string strTextToWrite = TextBox1.Text;
FileStream fStream = newFileStream (strPath,FileMode.Append);
fStream.Close();
StreamWriter sWriter = newStreamWriter(strPath);
sWriter.Write(strBuilder);
sWriter.Close();
//Text to word file
StringBuilder strBuilder = newStringBuilder();
strBuilder.Append("<h1 title='Header' align='Center'>Writing To Word Using ASP.NET</h1> ".ToString());
strBuilder.Append("<br>".ToString());
strBuilder.Append("<table align='Center'>".ToString());
strBuilder.Append("<tr>".ToString());
strBuilder.Append("<td style='width:100px;color:green'><b>amiT</b></td>".ToString());
strBuilder.Append("<td style='width:100px;color:red'>India</td>".ToString());
strBuilder.Append("</tr>".ToString());
strBuilder.Append("</table>".ToString());
// string strPath = Request.PhysicalApplicationPath + "\\document\\Test.doc";
string strPath = filename;
//string strTextToWrite = TextBox1.Text;
FileStream fStream = newFileStream (strPath,FileMode.Append);
fStream.Close();
StreamWriter sWriter = newStreamWriter(strPath);
sWriter.Write(strBuilder);

You probably need to seek to the end of the file? It seems like that would be the way to go. The Streamwriter starts at position 0, I think, and just clobbers whatever is there...

The changes should fix your append at least. Not sure if you are even getting it to compile though.

No problem. When you say "did nothing", I really don't know what that means.

I'm not sure if know, but you can append to any file you want. However, that doesn't mean that the reader (MS Word in this case) of the file will understand the data appended.

Anyway, if you will post your code so I can run it on my end, I will help you figure it out.

I've compiled the project and am looking at the warnings, particularly the missing reference: Microsoft.Office.Interop.Word

I am installing the class library download and will get back to you...

Ok, your text is being appended to the word document, as you have told it to do. The problem is how Word is interpreting the document. When debugging, I saw that the string "hank" was indeed getting in the document, so I played with some formatting changes in the code and used BinaryWriter instead of StreamWriter so I could position the stream 1 position away from the EOF:

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
            //StreamWriter sWriter = new StreamWriter(fStream);
            BinaryWriter sWriter = new BinaryWriter(fStream);
            sWriter.Seek(1, SeekOrigin.End);
            sWriter.Write("hany}");
            //StreamWriter sWriter = new StreamWriter(fStream);
            BinaryWriter sWriter = new BinaryWriter(fStream);
            sWriter.Seek(1, SeekOrigin.End);
            sWriter.Write("hany}");

Now, Word will display the appended text on a new page. Notice the addition of the closing brace in the text: "hany}". That is because I overwrote the closing brace already existing in the file (with Seek) and I wanted word to see "hany" before the final closing brace.

What you are dealing with at this point is Word scripting and you need to figure out how you can modify word documents externally or use some library that facilitates doing so, instead of using standard stream writers.

If the word "hany" is all you need appear at the end of the doc, and you wanted it to appear on the same page, you might be able to modify the export options to not fill the entire page with the table, then simply use the quick fix I just gave you.

Does this make sense?

As an after thought, have you considered just adding a field to the end of your report that you can set to text "hany", or whatever, so that when it is exported it will properly format it in the word document? Not sure exactly what you need to do for your project, but a text field in the report or page footer section seems like it might be the way to go.
