Chr Function

  • Articolo

This page is specific to the Visual Basic for Applications (VBA) Language Reference for Office 2010.

Returns a String containing the character associated with the specified character code.

Syntax

Chr(charcode)

The required charcode argument is a Long that identifies a character.

Remarks

Numbers from 0 – 31 are the same as standard, nonprintable ASCII codes. For example, Chr(10) returns a linefeed character. The normal range for charcode is 0 – 255. However, on DBCS systems, the actual range for charcode is -32768 to 65535.

Note

The ChrB function is used with byte data contained in a String. Instead of returning a character, which may be one or two bytes, ChrB always returns a single byte. The ChrW function returns a String containing the Unicode character except on platforms where Unicode is not supported, in which case, the behavior is identical to the Chr function.

Note

Visual Basic for the Macintosh does not support Unicode strings. Therefore, ChrW(n) cannot return all Unicode characters for n values in the range of 128 – 65,535, as it does in the Windows environment. Instead, ChrW(n) attempts a "best guess" for Unicode values n greater than 127. Therefore, you should not use ChrW in the Macintosh environment.

Example

This example uses the Chr function to return the character associated with the specified character code.

Dim MyChar
MyChar = Chr(65)    ' Returns A.
MyChar = Chr(97)    ' Returns a.
MyChar = Chr(62)    ' Returns >.
MyChar = Chr(37)    ' Returns %.
