I am using a web browser control to search the google for PDF files, by suppliying URL queries, then I am parsing results from webpages, then showing them in a ListView. I don’t know if this has any legal issues or not, would any on care to give advice / proof to back up your answer? ive also looked at BING http://msdn.microsoft.com/en-us/library/dd251056.aspx but cant seem to find any information on it other then commercialize (i.e., sell, rent, or lease) Bing results; as the software will be paid software im guessing this means im sellnig bind results? yahoo have a paid search http://developer.yahoo.com/search/boss/#pricing but dont seem to tell me how to sign up.
