 Hi,

 I think i may be out  of luck with this request be here goes. I'm looking to
 bring in HTML formatted text into power point keeping the formatting etc. I'm
 using Office 2007 and have managed this through the object model by opening
 the HTML in word and then copying the correctly formatted contents to a
 PowerPoint textbox. This is ok, and as a starting point suitable for me. I
 would however like to include any images within the HTML output and as yet i
 haven't been able to do this using the copy() method. If i use the
 copyAsPicture() and pasteSpecial () methods i can copy all marked up text as
 a whole however this doesn't scale properly and looks messy if any resizing
 has to be done.

 Has anyone done anything like this before or could suggest potential ways to
 resolve my issue?

 Thanks in advance.
