Getting editor HTML content from Visual Basic

I have a CM system in VB 6.0, and I'm editing HTML content using a VB form with a webbrowser activex component. When the user closes the form I have to check if there are any changes to save. To do that, I compare the last saved content with the following value: wbwebbroser.Document.frames(0).objContent.DOM.body.innerHTML
This solution stop working with version 2.0. Any idea about how to get this HTML value from VB in version 2.0?, I can only get the value property but it has the default HTML text.

Thanks
