How to load html and js files in the same directory, modifier some strings, and save them in vb2005

Question

Hi guys.

I would like to know if it's possible to do these things as above in the title.

The files will be in the same directory.

I have tried:

Dim htmlDoc As New System.Windows.Forms.HtmlDocument

But I get the error: the type has no constructor.

In fact, all I want to do is change a parameter in js function:

xmlDoc.load("a.xml")

I want to change the name of xml and then save the js and html files.

Thanks for your help
