StrConv
Returns a String converted as specified.
Syntax: StrConv( string, conversion [ , LCID ] )
- string
- required String expression to be converted.
- conversion
- required Integer. The sum of values specifying the type of conversion to perform.
- LCID
- optional The LocaleID, if different than the system LocaleID. (The system LocaleID is the default.)
The conversion argument settings are:
| Constant | Value | Description |
|---|---|---|
| vbUpperCase | 1 | Converts the string to uppercase characters. |
| vbLowerCase | 2 | Converts the string to lowercase characters. |
| vbProperCase | 3 | Converts the first letter of every word in a string to uppercase. |
| vbWide | 4 | Converts narrow (single-byte) characters in a string to wide (double-byte) characters. |
| vbNarrow | 8 | Converts wide (double-byte) characters in a string to narrow (single-byte) characters. |
| vbKatakana | 16 | Converts Hiragana characters in a string to Katakana characters. |
| vbHiragana | 32 | Converts Katakana characters in a string to Hiragana characters. |
| vbUnicode | 64 | Converts the string to Unicode using the default code page of the system. |
| vbFromUnicode | 128 | Converts the string from Unicode to the default code page of the system. |
INFO
These constants are specified by twinBASIC. As a result, they may be used anywhere in code in place of the actual values. Most can be combined, for example, vbUpperCase + vbWide, except when they are mutually exclusive, for example, vbUnicode + vbFromUnicode. The constants vbWide, vbNarrow, vbKatakana, and vbHiragana cause run-time errors when used in locales where they don't apply.
The following are valid word separators for proper casing: Null (Chr$(0)), horizontal tab (Chr$(9)), linefeed (Chr$(10)), vertical tab (Chr$(11)), form feed (Chr$(12)), carriage return (Chr$(13)), space (SBCS) (Chr$(32)). The actual value for a space varies by country/region for DBCS.
When converting from a Byte array in ANSI format to a string, use the StrConv function. When converting from such an array in Unicode format, use an assignment statement.
Example
This example uses the StrConv function to convert a Unicode string to an ANSI string.
Dim i As Long
Dim x() As Byte
x = StrConv("ABCDEFG", vbFromUnicode) ' Convert string.
For i = 0 To UBound(x)
Debug.Print x(i)
