Ripubblico qui un pezzo di codice LotusScript che non ho scritto io e che mi era servito tempo fa ma che ora non ritrovo più in rete .
Probabilmente il post originale se ne è andato ma potrebbe servire ancora a qualcuno .

Si tratta di una libreria (chiamata Netfunctions ) che permette di eseguire connect e disconnect da share di rete per scrivere o leggere dati, il tutto dall’interno di una procedura LotusScript.

Per prima cosa la libreria. Copiate ed incollate il codice qui sotto in una Script Library del vostro database e chiamatela NetFunctions (o come preferite):

Msgbox “Disconnect Error:”+Str(ErrInfo )+”. Net Disconnection Failed!”
End If
End Sub
‘ —- NetFunctions Library END—-

Poi createvi il vostro agent LotusScript che come prima istruzione deve avere un Use “NetFunctions” (o come l’avete chiamata).
Qui sotto il codice di esempio per vedere come utilizzarla:

 
' ---- Agent START ----
Option Public
Use "NetFunctions"

Sub Initialize
Dim session As New notessession

NetPath= “\\192.1.1.2\folder$”
MyFileName$=NetPath+”\myfile.txt”
MyUser =”windowsuser”
MyPass =”userpassword”
LocalDriveString=”” ‘ can be left empty

Call Connect
Call writeTofile(“test string to write”)
Call Disconnect

Call Connect
tmpread=readFromfile()
Print “File last updated: “+Cstr(Filedatetime(MyFileName$))
Call Disconnect
MsgBox tmpread

End Sub

Sub writeTofile(wrstr as String)
Open MyFileName$ For Output As #1
Print #1, wrstr
Close #1
End Sub

Function readFromfile()
Open MyFileName$ For Input As #2
Do Until Eof(2)
Line Input #2, tmp
tmp1=tmp1+tmp
Loop
Close #2
readFromfile=tmp1
End Function
‘ —- Agent END —-
