Purpose:
returns string converted as specified


Syntax:
StrConv(string1,conversion,LocalId)

Parameters Description

value specifying the type of conversion to perform.
Enumeration(member) Description()
VbStrConv.None() Performs no conversion
VbStrConv.LinguisticCasing() Uses linguistic rules for casing, rather than File System
(default). Valid with VbStrConv.UpperCase and VbStrConv.LowerCase only.
VbStrConv.Uppercase() Converts the string to uppercase characters.
VbStrConv.Lowercase() Converts the string to lowercase characters.
VbStrConv.ProperCase() Converts the first letter of every word in string to uppercase.
VbStrConv.Wide* Converts narrow (half-width) characters in the string to wide
(full-width) characters.
VbStrConv.Narrow* Converts wide (full-width) characters in the string to narrow
(half-width) characters.
VbStrConv.Katakana** Converts Hiragana characters in the string to Katakana characters.
VbStrConv.Hiragana** Converts Katakana characters in the string to Hiragana characters.
VbStrConv.SimplifiedChinese* Converts Traditional Chinese characters to Simplified Chinese.
VbStrConv.TraditionalChinese* Converts Simplified Chinese characters to Traditional Chinese.
