// This example is from http://idealprogrammer.com

// Example #1: 	StrConv(string1,conversion,LocalId) - returns string converted as specified
// string1 - Required. String expression to be converted.
// conversion - Required. VbStrConv member. The enumeration value specifying the type of

// LocalId - Optional. The LocaleID value, if different from the system LocaleID value. 
// (The system LocaleID value is the default.)
// 
// Enumeration(member)         Description()

// VbStrConv.Wide*              Converts narrow (half-width) characters in the string to wide
//  (full-width) characters.
