" Happy Hour"　in the entrainment of hypertext is vbs. From the source code can see that the author may be long-term expert in network programming, vbs knowledge about his proficiency in the use of many of the technical details are known, in particular the use of a type library (type library) success to avoid a security audit tool is amazing.
