Custom Browser Button Upgrade (C++/VS.net)

Sigma Systems is looking for a developer to update the compatibility of an an existing software item for us. We have all of the original development files for the software. We have a proprietary Internet Explorer 7 toolbar button that is currently not compatible with Internet Explorer 8. This button references a Microsoft Access 2007 database containing pre-populated variables for field items on a web form (the web form is propritary code of an offsite customer that we do not have the code for). ## Deliverables In Short: The function of this button is to populate a web form at the click of the button. The variables for those fields are stored in a Microsoft Access 2007 database located on our servers. We do not have access to the code of the web form. It currently only works with IE7 on Windows XP, we need it to work with IE8 on Windows 7.
