StrConv function

Returns a Variant (String) converted as specified.

Syntax

StrConv(string, conversion, [ LCID ])

The StrConv function syntax has these named arguments:

Part Description
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.)

Settings

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. (Not available on the Macintosh.)
vbFromUnicode 128 Converts the string from Unicode to the default code page of the system. (Not available on the Macintosh.)

*Applies to East Asia locales. **Applies to Japan only.

Note

These constants are specified by Visual Basic for Applications. As a result, they may be used anywhere in your 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.

Remarks

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)
Next
