simple web scrap project

project for web pages scrap requirements: the application required should: when the app starts, it should open a window for user to select (connection string to sql server database , table and field for the starting urls, number of threads, sql table/fields for the results extracted and the search engine to be used) also app should allow user to save above settings for future use (if possible , if not then the applicatoin at least keep the last updated user settings) when app starts extractions it should: 1-the app should start to read the number of threads from the source sqlerver table together with their respective ids into an array ,from sql server source table, "2-effect search in hidden mode on a special browser called 'tor browser' using one of the browser search engines called duckduckgo or disconnect" "3-extract the search results back into sqlserver 'results table' by filling following fields in sql table using regular expression to extract following fields from the search results: -id of the original searched url -the entire search result page as nvarchar(max) type -the individual search result (result page may contain 0 to 30 search results) as nvarchar(max) type -the url found in the search result as nvarchar(max) type -the companyname if found as nvarchar(255) type -the contact name if found as nvarchar(255) type -the website if found as nvarchar(255) type -the telephone if found as nvarchar(255) type -the fax if found as nvarchar(255) type -the mobile phone if found as nvarchar(255) type -the email address if found as nvarchar(255) type -the website address if found as nvarchar(255) type note if more than one email is found within the search result then app should creat counter number of sql server rows in the table having all above fields and each one of the emails found per row note the output sql table with all these fields would have being already created by the user and the app should fill the data into the proper fields" "after finish the threads, the app should flag the records in the original table "finished"" "and then continue to process the next threads/records from the source sql server table example of urls to be searched like "[login to view URL] for example ." note2: may be the app will need to refresh tor browser every 2-3 runing of threads so that to avoid captcha, and to refresh tor, it is manually like clicking the green onion on the top left hand side on the bar and select new identity" note3: the app should determine that the search pages were fully loaded before extracting data important factors: 1- the speed should be to maximum (target to achieve minimum of 3 searches per second) 2-the app will be ran on several different machiens and all rning versions will be accessing the same sql server data base/table hence each app versionshould flag the starting records it read as 'used' to avoid other running version to take same records
