Web Browser control and open/edit a MSWORD document

I am very new to VB .net and windows programmig, but over a few days have read a few articles. But I really need some help from you guys!

I am trying to create a DLL file which would be called from a HTML using javascript. I am using a COM class in my VB .NET application. It is COM visible and members along with Functions are set COM visible.

The idea is to use the Web Browser control and open a MSWORD document inside the IE frame. I am struggling a lot with this. If there are any experts out there, can they please share the steps I need to perform to do this. Here is what I have done so far with no success.

1) Created a VB .net project with a COMClass. Com visibility is set true for most of the memebers and functions.

2) Added reference to System.windows.forms to get hold of the usercontrol and web browser (here i am trying to create the UI to hold the web browser control) I try to set all this in the New() i.e contructor of the class.

3) Added a reference to Interop.Word so that I can cast the document given by the webbrowser control to a MSWORD instance and access its properties.

My projects builds without any problems. But in the javascript, it throws error when I try to access the DLL files members or function. I am lost and wonder if I can make it work. Do you see any fundamental problems with what I am trying to do?

Any suggestions are valuable. Thanks!
