Grab Selected/Highlighted Text from web page and view the source

[didijc]

Happy New Year everyone...

I created a simple Web Browser using the inbuilt Web Browser component...now I want to be able to select/highlight some HTML content (text, images, media clips, etc.) on any website and view the HTML source code for the selected/highlighted content.

I've seen numerous examples, IHTMLTxtRange, WebBrowser1.Document.Selection.createRange, CurrentDoc.selection.createRange().htmltext, etc. but none of them work - I've seen javascript examples, vbscript examples...what I need is a way to do it in Visual Basic 2008...can someone help me

Here's what I have so far...

Public Class Form1
