If Name = "a111a111a111" Then Exit Sub

Hi,
I would like to do the following,
(real sorry for the points)

How do you convert a string with a file path from this C:\Canada\ONT\Ottawa
to this
..\..\
assuming I wanted to add a Link to Canada while the inital HTML file was saved in Ottawa.

Again, sorry for the points.

I use a function that I wrote that will split up a a string by a userdefined character.


I would do something like this

dim total as long
dim tmpArray as variant

  total=parsestring(tmpFilePath,"\",tmpArray)

 

  using the example you gave us:
      total = 3
      tmpArray(0)="C:"
      tmpArray(1)="Canada"
      tmpArray(2)="ONT"
      tmpArray(3)="Ottawa"

  notice that the 3 was the number of \ is found!

Good Luck!

Here is the function:

Function ParseString(LookIn As String, Search As String, ByRef ReturnArray As Variant) As Long
'
' Function Name:    ParseString
'
' Author:           JF Software (Jason R. Fayling)
'                   jfayling@glasscity.net
' Date:             1/10/97
'
' Inputs:           LookIn  (STRING)        String to use
'                   Search  (STRING)        What to look for in string
'                   ReturnARRAY (VARIANT)   Any found will be stored here
'
' Outputs:          ParseString (INTEGER)   Number of items in ReturnArray
'                                           starting with zero. If no item
'                                           was found, then returns -1
'
'                   ReturnArray (VARIANT)   Found items from string
'
' Purpose:          ParseString will take a string and seperate it into
'                   user-defined parts.
'                   Example:
'
'                       Dim i as Integer
'                       Dim j as integer
'                       dim Temp as variant
'
'                       i=ParseString("10/24/97","/",Temp)
'
'                       for j=0 to i
'                           msgbox Temp(j)
'                       next j
'
'                   This will display 10 then 24 then 97

Dim X As Long
Dim start As Long
Dim pos As Long
Dim track As Long
ReDim TempHolder(Len(LookIn)) As String


    track = 0
    start = 1
   
    ' Start at the beginning of string and move down until it finds
    ' character it is looking for. Once it finds the character, it
    ' places everything before it and after the last found item into
    ' a new element in an array
   
    Do
        pos = InStr(start, LookIn, Search, vbBinaryCompare)
        If pos > 0 Then
            TempHolder(track) = Mid$(LookIn, start, (pos - start))
            track = track + 1
            start = pos + Len(Search)
        End If
    Loop Until pos = 0
   
    ' Make sure everything has been copied into Temp array
    TempHolder(track) = Mid$(LookIn, start, Len(LookIn))
       
    ReDim tempholder2(track)
   
    ' Move only elements with data in them
    For X = 0 To track
        tempholder2(X) = TempHolder(X)
    Next X
   
    Erase TempHolder
   
    ' Return Array is a variant so it can be passed an array
    ReturnArray = tempholder2
   
    If track = 0 Then
        ' Nothing was found
        ParseString = -1
    Else
        ParseString = track
    End If

End Function

Thats a very good function,
although, would you mind helping me achieve the task asked in the Question?
