  php mysql validation escaping sanitization
  I’m just discovering PHPs sanitize and Validate filters, and I had been using MySQL’s mysql_escape_string to stop SQL Injection.Now I discover that PHP can also help and I guess logically these procedures are not exclusive in their function: ie you can sanitize and validate in PHP and still arrive at a situation where escaping is necessary.Am I right or am I overlooking something?

  I write an application, that parse data from boards on the airport sites – Sheremetyevo (http://svo.aero/timetable/today/) and Domodedovo (http://www.domodedovo.ru/ru/main/airindicator/flightnew/). I create an object URL with the link of the site. Next, I call the method openStream. After that this stream is used with the parser HTMLEditorKit. With Domodedovo it works pretty good, but with the Sheremetyevo airport program behaves strangely. First, a certain number of launches of the application

  c# stream icalendar
  What’s the easiest way to filter a stream/reader line-by-line in c# (somewhat like putting sed in the middle of a pipeline). I want to feed an iCalendar file to DDay.iCal but DDay.iCal dies on “VERSION:5.1.1” because it wants a number or number SEMICOLON number (where number is digits (DOT digits)? so the last “.” is unexpected). What I want to do is filter the VERSION: line to something harmless like “VERSION:5.1” so the parser doesn’t die.Update: OK, here’s a sample: BEGIN:VCALENDAR PRODID:-//
