Nun, jetzt habe ich die Zeit gefunden, doch noch mal selbst nachzugrübeln (dabei soll man ja am meisten lernen) und an der Stelle gegraben, an der der Fehler auftrat.
Fehler: "Type mismatch on external name CSVFILE" beim Aufruf der Zeile
Set csv = New CSVFile("","FBI", st_Fields, type_Fields)
--> type mismatch. Also muss ein Datentyp beim Aufruf falsch sein. Den einzigen Parameter, welchen ich hinzugefügt habe, ist
type_Fields.
Den Datentype habe ich auf Variant geändert.
Dim type_Fields(1 To 5) As Variant
Siehe da. Der Aufruf funktioniert nun ohne Fehler. Muss blind gewesen sein.
In der Library
ImportCSV habe ich dann noch weitere Änderungen vorgenommen. Vor allem stellte sich heraus, dass man die Felder, welche eben als "Number" gekennzeichnet sind, gleich als Wert ("value", Funktion Val) in das Array
v_ValueArray gespeichert werden sollten.
Schließlich werden die Dokumente auch über den Schlüssel in der ersten Spalte gesucht. Und wenn dies eine Zahl (hier ein Integer) ist, so muss man auch mit einer Zahl und nicht mit einem String suchen.
' LOOKUP THE DOCUMENT
Set doc_Current = vw_Lookup.GetDocumentByKey(v_ValueArray(1), True)
Eigentlich eine Selbstverständlichkeit, aber ich möchte es hier trotzdem erwähnen: Achte bei gebrochenen Zahlen darauf, in welchem Format diese in der CSV-Datei abgespeichert sind. Bei Einstellungen "Deutschland"/"Germany" in den "Regional Settings and Language" werden Zahlen standardmäßig mit Dezimaltrennzeichen "Komma"/"," statt dem "Punkt"/"." geführt. Es sollte darauf geachtet werden, dass gebrochene Zahlen in der CSV-Importdatei mit "Punkt"/"." als Dezimaltrennzeichen geführt werden, denn sonst schneidet die Funktion Val die Nachkommastelle einfach weg.
Inzwischen habe ich den Code weitgehend getestet und dabei festgestellt, dass man in CSV-Dateien zum Import nicht nur Text (String) und Nummern findet, sondern auch noch Datum (Date) und Zeit (Time), aber auch auch Datum und Uhrzeit in einem Feld (DateTime). Dies alles habe ich nun berücksichtigt (siehe case Anweisungen)
