c# - Opening Word Document on Client Side from Asp.net Application

Question

We need to open a word document which is located on a server on the clients machine using Microsoft Word. The solution is working locally however when deployed on server then only thing that happens is that the winword.exe is started on the server. Is this possible to do using interop or javascript?

this is the code till now

Microsoft.Office.Interop.Word.ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

object file = FilePath + FileName;
lblError.Text = lblError.Text + file.ToString(); 
object readOnly = false;
object objTrue = true;
object missing = System.Reflection.Missing.Value;
object emptyData = string.Empty;
wordApp.Visible = true;
Microsoft.Office.Interop.Word.Document aDoc                         =
wordApp.Documents.Open(ref file,
         ref missing, ref readOnly,
         ref missing, ref missing, ref missing,
         ref missing, ref missing, ref missing,
         ref missing, ref missing, ref objTrue);

aDoc.Activate();

You have to keep in mind that the client and server are running on two different machines. The server can't start a program running on the client machine.

Also, FYI, never use Office Automation from an ASP.NET application. Those APIs were designed for use in a desktop application. They won't work properly, are unsupported, and may even violate your Office license.
