Document History Function

I found that in many of my applications I was always recording document history (creation, changes, workflow events, etc.) in a multi-value text field usually at the bottom of the document. Most of the time I took the easy way out and just kept appending history items to the field, this results in a oldest to newest list. Most often users want a list that is most recent (newest) to least recent (oldest). I wrote the WriteHistory function...

to accomondate both types of history lists. The ReverseMVI (Reverse Multi-value item) was written to correct my past mistakes and reverse the order of exisitng histroy lists. Function WriteHistory(historyText As String, mode As Integer, historyItem As String, doc As NotesDocument) As Integer ' -------------------------------------------------------------------- --------------------------------------------------------- ' historyText - The text string to be written. ' mode - 0 = new item appended to the bottom of the list. 1 = new item is added at the top of the list. ' HistoryItem - string name of the item to add the historyText to. ' doc - the NotesDocument that contains the history item. ' -------------------------------------------------------------------- --------------------------------------------------------- ' Time Stamps in a mmm d,yyyy h:mmam/pm format such as Oct 11,1999 6:17pm ' -------------------------------------------------------------------- --------------------------------------------------------- Dim stampDate As String Dim stampTime As String Dim item As NotesItem Redim newHistory(0) As String Dim x As Integer ' Date/Time Formats stampDate = "mmm d,yyyy" stampTime = "h:nnam/pm" Set item = doc.GetFirstItem(HistoryItem) If item Is Nothing Then ' Just in case the item does not already exist on the document Set Item = New NotesItem( doc, HistoryItem, "") End If If mode = 0 Then ' New items appear at the end of the history field Call item.AppendToTextList(Format(Date(),stampDate) & " " & Format(Time(),stampTime) & " - " & HistoryText) Else ' New items appear at the top of the history field If item.text = "" Then ' Handle a current history item with just a single NULL value. Redim newHistory(0) As String Else Redim newHistory(Ubound(item.values)+1) As String ' Transfer previous history entries For x = 0 To Ubound(item.values) newHistory(x+1) = item.values(x) Next End If ' Add the new history entry newHistory(0) = Format(Date(),stampDate) & " " & Format(Time(),stampTime) & " - " & HistoryText ' Rewrite the hsitory list item.values = newHistory End If WriteHistory = True End Function Function ReverseMVI(itemName As String, doc As NotesDocument) As Integer ' -------------------------------------------------------------------- ----------------------------------------------- ' This function will reverse the order of the values in a multi value field ' itemName - Field Name of the history list to reverse. ' doc - The notes document object in which the itemName field exists. ' Example: Original values... 1,2,3 After ReverseMVI... 3,2,1 ' -------------------------------------------------------------------- ----------------------------------------------- Dim item As NotesItem Dim nEntries As Integer Redim newHistory(0) As String Set item = doc.GetFirstItem(itemName) nEntries = Ubound(item.values) Redim newHistory(nEntries) As String Forall v In item.values newHistory(nEntries) = v nEntries = nEntries - 1 End Forall item.values = newHistory ReverseMVI = True End Function
