  Hi, What exactly areyou trying to do? Could you provide a little more information?
  
  If you have a string, yuou can use the InStr function to discover whether it contains a certain substring/character.  eg.
  
  Dim myString As String
  myString = "'John"
  If InStr(1, "myString", "'") > 0 Then
       'The string is present
  End If
  
  Or you can remove/replace certain characters using the Replace Command:
  myString = Replace(myString, "'", "")

  I think you need to escape the quotes, ie. use two single quotes instead of 1:
  
  ADO.RecordSource = "SELECT * FROM tblSecurity WHERE [Password]= '''John'"

  As a side issue: I would advise against storing passwords as plain text, at the very least use a simple transposition algorithm to encrypt your string.  Heres a simple example, just encrypt the string before you store it in the db, and when you come to compare a password against it, just encrypt the string and compare the two encrypted strings:
  
  Function Encrypt(ByVal theString As String) As String
      Dim x, i, tmp As String
      For i = 1 To Len(theString)
          x = Mid(theString, i, 1)
          tmp = tmp & Chr(Asc(x) + 1)
      Next
      tmp = StrReverse(tmp)
      Encrypt = tmp
  End Function
  
  Private Sub Form_Load()
  Dim strRaw, strEncrypted As String
  strRaw = "John"
  strEncrypted = Encrypt(strRaw)
  Debug.Print strEncrypted
  End Sub
