How to export the contents of a Domino.Doc Library on the local file system? (part II)

Pubblicato il da

This is the scond part of a two parts article.

The Cabinet documents created by the PopolaCabinets agent stores also the total binders numbers and the total documents number.
There are also two datetime fields used to store the start and the end time of the export.

The Cabinet form to store cabinet and binders info.

The EsportaCabinet agent

Here follows the code for the EsportaCabinet agent: is the agent that create the file system structure and populates it with the Domino.Doc attachments.

Option Public
Use "OpenLogFunctions"

The function PulisciDirName

This function replace the non permitted chars in filename with the ones specifed in the global ToArray string array. The function checks also for foler ending with one or more “.” (dot) and replace the trailing dot(s) with “_” (underscore).

Function PulisciDirName (dirname As String) As String
	On Error Goto processError
	Dim i As Integer
	Dim dot As String

	directory$ = dirname
	suffDir$ = directory$
	i = 1
	dot = ""
	While Right(suffDir$, 1) = "."
		dot = dot + "."
		suffDir$ = Left(directory$, Len(directory$) - i)
		i = i + 1
	Wend
	directory$ = suffDir$ & dot

	directory$ =Replace(directory$, FromArray,	ToArray)

	PulisciDirName = Trim(directory$)
	Exit Function
processError:
	Call LogErrorEx("PulisciDirName failed", SEVERITY_LOW, Nothing)
	PulisciDirName = Trim(directory$)
	Exit Function
End Function

The function NameShortner

If the full pathname is greater than 255 chars the Dir$ function crashes the notes client.
So before saving the attachment to disk we check the length and we shorten the filename if needed.
In order to obtain unique file name we use the passwordGenerator function to append a 2 chars random suffix.

Function NameShortner(fulldirpath As String, docTitle As String, allegato As String, v As Long, d As Long) As String
	Dim fullwithtitle As String
	Dim toShort As Integer

	fullwithtitle = fulldirpath & "\" & docTitle
	If Len(fullwithTitle) < 239 Then  		NameShortner = docTitle  	Else  		toShort = 250 - Len(fulldirpath)  - 2  		If toShort > 0 Then
			NameShortner = Left(docTitle, toShort) & passwordGenerator(2)
			While Not(Dir( fulldirpath & "\" & NameShortner)="")
				NameShortner = Left(docTitle, toShort) & passwordGenerator(2)
			Wend
		Else
			NameShortner = ""
		End If
	End If
End Function

The function CreaDirFromCat

This function takes the binder categories and generates a file system path for these categories. It appends the _c suffix at each created folder.

Function CreaDirFromCat(sCurrDir As String, sCatName As String) As String
	On Error Goto processError
	Dim folders As Variant

	CreaDirFromCat  = ""
	folders = Split(sCatName, "\")

	For x=0 To Ubound(folders)
		fold$ = folders(x)
		fold$ = PulisciDirName(fold$)
		sCurrDir = sCurrDir & "\" & fold$ & "_c"
		ret=CreateDir(sCurrDir)
		CreaDirFromCat = CreaDirFromCat & "\" & fold$ & "_c"
	Next
	CreaDirFromCat = Right(CreaDirFromCat, Len(CreaDirFromCat)-1)
	Exit Function
processError:
	Call LogErrorEx("CreaDirFromCat failed", SEVERITY_LOW, Nothing)
	CreaDirFromCat = ""
	Exit Function
End Function

The function GetExt

It returns the filename extensions.

Function GetExt(path As String) As String
	On Error Goto errorHandler
	Dim table As Variant
	Dim fileName As String

	fileName = path
	If Instr(fileName, "\") > 0 Then
		table = Split(Trim(fileName), "\")
		fileName = table(Ubound(table))
	End If
	If Instr(fileName, ".") > 0 Then
		table = Split(fileName, ".")
		GetExt =  "." & table(Ubound(table))
	Else
		GetExt = ".xxx"
	End If
	Exit Function
errorHandler:
	Call LogErrorEx("GetExt failed " & path , SEVERITY_MEDIUM, Nothing)
	GetExt = ".xxx"
	Exit Function
End Function

The function SetDate

Set the specified field of the specified document with the current date/time.

Function SetDate(doc As NotesDocument, strFieldName As String)

	Dim tdate As New NotesDateTime(Now())
	Call doc.ReplaceItemValue(strFieldName, tdate)

End Function

The sub ExportDocAndVersions

To be descripted.

Sub ExportDocAndVersions(db As NotesDatabase, theDocument As Variant, fulldirpath As String, docTitle As String, Binder As String, Cabinet As String)
	On Error Goto processError
	Dim revHistDocs As Variant
	Dim revHistDoc As Variant
	Dim k As Long
	Dim v As Long
	Dim d As Long
	Dim IsVersion As Boolean
	Dim docTitle_ori As String

	docTitle = PulisciDirName(docTitle)

	Set revHistDocs = theDocument.RevisionHistoryDocuments
	k = revHistDocs.Count
	If (k>0) Then
		For i = 0 To (k-1)
			Set revHistDoc = theDocument.RevisionHistoryDocuments.ItemByIndex(i)
			IsVersion = theDocument.IsVersion
			'If IsVersion Then
			attach$=revHistDoc.Filename

			v = revHistDoc.VersionNumber
			d = revHistDoc.DraftNumber

			filename$=fulldirpath &"\" & docTitle &"_-_" & AppendVersion(attach$, v, d)
			If (Len(filename$) < 250) Then
				If attach$ <>""  And Dir$(filename$) = "" Then
					Call revHistDoc.GetContents(filename$)
					Call LogDoc(db, revHistDoc, filename$, docTitle, Binder, Cabinet, "")
				End If
				Call LogEvent("Esportazione versione - " & attach$ & " - nel path " & filename$, SEVERITY_LOW, Nothing)
			Else
				docTitle_ori = docTitle
				docTitle = NameShortner(fulldirpath, docTitle, attach$, v, d)
				filename$=fulldirpath &"\" & docTitle & "_ver" & Cstr(v) &  "-" & Cstr(d)  & "." &GetExt(attach$)
				If (docTitle = "") Then

					Call LogEvent("NESSUNA esportazione versione - " & attach$ & " - nel path " & filename$, SEVERITY_LOW, Nothing)
					docTitle = docTitle_ori
				Else
					Call revHistDoc.GetContents(filename$)
					Call LogDoc(db, revHistDoc, filename$, docTitle_ori, Binder, Cabinet, "path accorciato: " & docTitle)

				End If

	Exit Sub
End Sub

The function CreateDir

Nothing to say.

Function CreateDir(sDirName As String) As Boolean

	End If
	Exit Function
processError:
	Call LogErrorEx("PulisciDirName failed", SEVERITY_LOW, Nothing)
	CreateDir = False
	Exit Function
End Function

The Document form to store document info and the exported attachment path

The function LogDoc

How does it works?

On the C drive of the PC folder create the domdoc folder.

Here you’ll store the exported attachments.
From this folder an agent will create a directory tree based on the hierarchy of Domino.Doc

  • Rooms (folder is always present – no documents)
  • Cabinet (folder is always present – no documents)
  • Folders categories (folder(s) is(are) optional(s) – no documents)
  • Binder Folder (folder is always present – any document can be found here)
  • Documents

For exporting documents and their versions the following naming scheme will be used:
<document-title> _-_ _ <filename_without_extension> _ver<version>-<draft>.<extension>

  • <document-title> is the title that was given to the document in Domino.Doc. Most of the time coincides with the filename attachment without the extension.
  • <filename> is the name of the attachment
  • <version> is the version number
  • <draft> is the number of draft

To support the export procedure you create two Lotus Notes database.

The first, APPL (edomdocs-v1.nsf), “supervises” the export process.

The second LOG (OpenLog1_5Apache.nsf) is the log of the various exports.

APPL contains an agent (PopolaCabinets) that examines the structure of Domino.Doc and creates so many documents for those cabinets to be exported.

For each cabinet is gathered a wealth of information, including the number of binders and documents it contains.

Then selecting one or more cabinets from the Cabintes view in Lotus Notes client, you can launch its export. The choice is due to the fact that the procedure is time intensive and also it is believed that many cabinet does not need to be exported.

After starting the export a document will be created in the same database (one document for each of the exported files).

If the document can not be exported because its fullpathname exceeds the limit of 250 characters, the document created in APP report the event and it trys to “shorten” the exported filename.

NOTES: The titles of ROOMS, CABINETS and the categories were “filtered” by replacing illegal characters with the character _The / character (often used in these names) has been replaced with the character].

The procedure always checks the presence of fullpathname: if the directory or file already exist, they are overwritten. This is not true for “shortned” filename because we generate a random file name.
