Public Function Trim (str As String) As String

Parameters

str: String

Required. Any valid String expression.

Returns

String

A string containing a copy of a specified string with no leading spaces (LTrim), no trailing spaces (RTrim), or no leading or trailing spaces (Trim).

Examples

This example uses the LTrim function to strip leading spaces and the RTrim function to strip trailing spaces from a string variable. It uses the Trim function to strip both types of spaces.

' Initializes string.
Dim testString As String = "  <-Trim->  "
Dim trimString As String
' Returns "<-Trim->  ".
trimString = LTrim(testString)
' Returns "  <-Trim->".
trimString = RTrim(testString)
' Returns "<-Trim->".
trimString = LTrim(RTrim(testString))
' Using the Trim function alone achieves the same result.
' Returns "<-Trim->".
trimString = Trim(testString)

Remarks

The LTrim, RTrim, and Trim functions remove spaces from the ends of strings.
