I have an almost completed application based on SharePoint 2010 and InfoPath 2010 forms. I think what is now needed is a custom webpart that will bring in 3 web part connection parameter fields from the forms in SharePoint, open a link to an HTML site, and
prepend some static and dynamic HTML to the stream and open a new window that will allow a user to enter credit card data into the https site thus opened. Next is to write back the results of the transaction to a form column paid_in_full yes/no, that I in
turn can release the goods to the user.
Any suggestions as to how to accomplish this in a web part or other is greatly appreciated!
