build word 2003 document from web application

[Guest]

i need to create a new word 2003 document within a c# web application. this
is the code i´m using

private Microsoft.Office.Interop.Word.ApplicationClass WordApp = new
Microsoft.Office.Interop.Word.ApplicationClass();

object missing = System.Reflection.Missing.Value;

object docType = 0;
object isVisible = true;

// Create a new Document, by calling the Add function in the Documents
collection
Microsoft.Office.Interop.Word.Document aDoc = WordApp.Documents.Add(ref
missing, ref missing, ref docType, ref missing);

WordApp.Visible = true;
aDoc.Activate();

but i´m getting an error in aDoc.Activate() line

this is the error

error:

[NullReferenceException: Object reference not set to an instance of an
object.]
worddoc.StandardReport.Page_Load(Object sender, EventArgs e) in
c:\mcms\worddoc\standardreport.aspx.cs:39
System.Web.UI.Control.OnLoad(EventArgs e) +67
System.Web.UI.Control.LoadRecursive() +35
System.Web.UI.Page.ProcessRequestMain() +750

any help would be appreciate or any suggestion about how to do this process

thanks in advance

COM automation to Word is not recommended from ASP.NET.

Instead you could use one of these techniques:

If you have more advanced needs, I'd recommend going with a 3rd party
component, such as one of these:
