Since I've started this website, I've tried to help out my fellow programmer by posting snippets of code that I felt would be useful. As time has gone on, finding any or all of these items on the site can be a bit of a chore. As such, I've designed this library (CUL, pronounced "cull") as a set of utilities to deal with fairly common issues, as well as some uncommon ones, with regard to development including:

  • Multiple blurring techniques including box blur, Gaussian blur, Kuwahara, and Symmetric Nearest Neighbor blur
  • Bump map and Normal map helpers

  • Get emails
  • Get the GAL
• SQL query helper
• File formats/Microformats
  • XMDP

  • vCalendar/hCalendar
  • iCalendar (with email sending capabilities, cancellation, and automatically putting it in Exchange)
  • APML
  • OPML
  • FOAF
  • XFN
  • CSV
  • RSD
  • BlogML
  • INI
• Code to render a web page to BMP file
• Icon extraction from a file
• WebBrowser control cache clearing class
• Reflection helper
• Randomization
  • Including string randomization based on allowable characters, date randomization, Color, Enum, TimeSpan, and Lorem Ipsum generation.
• Environment information
• Process management
• Error/Information gathering
• Track back and ping back helper classes
• Math related classes
  • Matrix
  • Vector3
  • Set
• Data types
  • Pair
  • Triple
  • Vector
  • Bag
  • List
  • ListMapping
• Base classes for various patterns including
  • Singleton
  • Factory
• OAuth helper class
• Classes to help with various media services including
  • YouTube
  • Hulu
  • Netflix
• Classes to help with events
• WMI query helpers
• SQL Server structural analysis helpers
• And some basic data conversion

The zip file contains the solution (Visual Studio 2010), all source files (in C#), compiled DLLs (against .Net 4.0) and documentation. Most of the classes should work with .Net 2.0/3.5 but only a few will work with anything earlier.
