VBA example

Note: Examples that follow demonstrate the use of this function in a Visual Basic for Applications (VBA) module. For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box.

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.

Dim MyString, TrimString
MyString = " <-Trim-> " ' Initialize string.
TrimString = LTrim(MyString)
' TrimString = "<-Trim-> ".
TrimString = RTrim(MyString)
' TrimString = " <-Trim->".
TrimString = LTrim(RTrim(MyString))
' TrimString = "<-Trim->".
' Using the Trim function alone
' achieves the same result.
TrimString = Trim(MyString)
' TrimString = "<-Trim->".
