In banking I've used it when creating transaction files where the record has a
fixed length and all fields has to be either numeric or alfanueric and padded
with zeros or spaces to fill.
This function takes a teststring (textToPad) and adds characters before or
Function padText(textToPad As String, newLen As Integer, padWith As String,
psFix As String) As String
'String; text to be "padded"
'Integer; Length of the new String (total length)
'String; What to fill With
'String; determines whether to Add it as prefix or suffix to the String
Dim orglen As Integer
Dim tmpString As String
Dim tmpPad As String
orglen = Len(textToPad)
' returns If the new length is the same as the old length
If orglen = newLen Then
padText = textToPad
If orglen > newLen Then
' New length cannot be less than the original length
Msgbox "Error textToPad: Instring " + textToPad + " length " +
" is less than new length " + Cstr(newLen)
tmpPad = String$(newLen - orgLen, padWith)
If psFix = "P" Then
tmpString = tmpPad + textToPad
Elseif psFix = "S" Then
tmpString = textToPad + tmpPad
Msgbox "textToPad contains wrong arguments"
If Len(tmpString) <> newLen Then
Msgbox "Error textToPad: New padded string " + tmpString +_
" is larger than the original string " + textToPad
padText = tmpString
