Capturing HTML input values using a BHO

Question

Hi all,

i am a complete nobbie to BHO and C++. This is what i want to achieve.

Using various code samples, i have been successful in installing a BHO in my Internet Explorer. I am currently making use of the Invoke method to search for DISPID_HTMLDOCUMENTEVENTS2_ONCLICK and have been successful in capturing the event.

How can i access a HTML input on the page is filled up with values? (eg. i navigate to www.gmail.com, key in some values into the username and password, and my BHO is activated upon the onclick event?)

Code examples or link to documentation would be fantastic help

regards Meric
