This blog uses some different approaches to solve some common tasks.  I have found there are many different ways to approach problems and the proper solution often depends on other constraints.  I addition to the techniques mentioned in this blog, you can use SmartObjects with no code to accomplish the same results.

@chrisgThank you for your post. I'm honored:)

@DavidLIndeed there are many ways to solve problems. The code in my blog is just one of many ways you can use. If you have another / better way, please let me know :)@japergisMy team seldom use SmartObjects. The first two example code in my blog is given by K2 Singapore guys. So I just use it. If you have better / simpler way, please let me know :)

 Sorry for the late reply, I seldom check the threads in k2underground.
