Do you have the Microsoft DAO Object library loaded?  If not, try that.

brunchey,
I don't think that is the problem.  Every time a match is found, it is replaced with something else.  So even if it starts at the beginning again, it won't find the same occurrance, because it won't be there anymore.

assume temp = "test text"
search for "t" and replace with "X"

first pass starts at first character finds "t" at position 1 changes to X"
now temp = "Xest text"
second pass starts at first character finds "t" at position 4
now temp = "XesX test"

brunchey,
Please accept my apology.  I failed to check the values of sfind and sreplace.  You are absolutely correct.  Your answer should solve the problem.  Good work.

Sekans

hess,
You do need to initialize the variable ll_begin.

Dim ll_begin as Integer
ll_begin = 0

put this before the Do...Loop

Why are there to loop statements at the end of the answer is one not suposed to be there

I'll test it now and if it works i'll give you the 135 points

could you please rewrite the answer so that the whole szReplace function is included, From "Public Function" to "End Functioin" I've been working with vb for only a couple of days and i would like to be able to just paste it in.

Commented:
Never Mind. It works great and thanks for the help sekans and Brunchey. But why did you say to set II_Begin to 0 instead of 1 sekans

Commented:
That was a mistake, 1 is correct.

Commented:
Function szReplace(szText As String, szFind As String, szRepl As String) As String
'-- This function replaces all occurances of szFind with szRepl within
          '   szText and returns the resulting string.

              Dim nThere As Long
              Dim szTemp As String
              Dim ll_begin
              '-- Copy the incoming text so that szText is not altered.
              szTemp = szText
              ll_begin = 1
              '-- Go into a loop
              Do
                  '-- Is szFind part of szTemp?
                  nThere = InStr(ll_begin, szTemp, szFind)
                  If nThere Then
                      '-- Yes. nThere is now the position of szFind within szTemp
                     
                      '        [---------- A ----------]   [-B -]   [------------- C ----------------]
                      szTemp = Left$(szTemp, nThere - 1) & szRepl & Mid$(szTemp, nThere + Len(szFind))
                      ll_begin = nThere + Len(szRepl)
                  Else
                      '-- No. There is nothing more to do, so exit the loop
                      Exit Do
                  End If
              Loop

              '-- Assign szReplace to the szTemp string, which contains the
              '   modified original text.
              szReplace = szTemp
End Function
