I have a big string
{\rtf1\ansi\ansicpg1252\deff0\deftab720{\fonttbl{\f0\fswiss MS Sans Serif;}{\f1\froman\fcharset2 Symbol;}{\f2\fswiss Abadi MT Condensed;}{\f3\fswiss MS Sans Serif;}{\f4\fswiss\fprq2 System;}}

I Need to chop off the last "}" and add to so I made this
Code:
Public Sub Append_rtf(toappend As String)

Dim fulllenght, insertpoint As Integer
Dim oldrtf, newrtf As String
'****************************************
' - created Oct ,14 2000 by []Private[]
' adds formated text to a RTB
'
'****************************************

'assign varriables
oldrtf = Space(Len(header) + Len(toappend))
oldrtf = header$
Debug.Print oldrtf
fulllenght = Len(oldrtf)
insertpoint = InStrRev(oldrtf, "}") ' assumes that the end of the rtf code is like "\par Test}"
'MsgBox insertpoint
'do a midstring here to insert the line
 Mid(oldrtf, insertpoint, Len(toappend) + fulllenght) = toappend
 Debug.Print oldrtf
End Sub
and call it like this
Code:
Append_rtf "\deflang1033\pard\plain\f2\fs20\cf12 test }"
but it doesn't work . It only overwrites the last "}" in the target string with the first char in the string to append . Why ?
