Generazione codici 128 codici a barre con Excel VBA

Sto cercando di ottenere codici a barre codice 128 generati in Excel, tramite l'uso di VBA. Ho trovato una classe VBA che qualcuno ha creato e condiviso tramite VBForums (successivamente modificato per funzionare con Excel VBA), ma ho problemi a farlo funzionare.Generazione codici 128 codici a barre con Excel VBA

Se si utilizza il codice riportato di seguito in un foglio di calcolo abilitato per Excel Macro, viene visualizzato l'errore #VALORE quando si tenta di utilizzare la funzione Code128_Str() su qualsiasi input.

Mi mancano le competenze necessarie per eseguire correttamente il debug del codice. Se questo script può essere corretto, penso che sarebbe immensamente utile a molte persone che cercano di fare lo stesso. Lo script in questione utilizza il font gratuito per generare i relativi codici a barre di output Code 128.

'Il motivo usuale per ottenere #Value con un UDF è che uno degli argomenti di input non possono essere convertiti alla type' corretta secondo http://stackoverflow.com/ domande/4170983/vba-udf-valore di ritorno Chiamate la funzione in Excel come '= Code128_str (" TESTING ")'? Con il doppio preventivo – Larry

Grazie Larry! Stavo chiamando la funzione come '= Code128_Str (A1)' (dove A1 è una cella con il valore da convertire), ma ho anche provato a chiamarla come '= Code128_Str (" TESTING ")' e '= Code128_Str (1234)'. Tutti questi restituiscono lo stesso errore "# VALORE". Idealmente, ho bisogno di capire come eseguire correttamente il debug di questo codice, perché al momento non ci sono errori dal codice stesso, ma da qualche parte lungo la linea, qualcosa sta causando problemi. – shigzy

Ciao OP, la mia domanda ora è che stai chiamando la funzione dal foglio di calcolo Excel o in VBA? – Larry

Ecco come usarlo È necessario avere

Module (Per memorizzare l'UDF funzione che è possibile chiamare dal foglio di calcolo Excel )
Modulo di classe (Per memorizzare l'oggetto classe t)

modulo Dove Class1 è il nome del modulo di classe

Public Function Code128_Str(ByVal Str As String) As String 
Dim c As Class1 
Set c = New Class1 
Code128_Str = c.Code128_Str(Str) 
End Function

modulo di classe

Perfetto :). Grazie mille per il tuo aiuto, Larry. Voterò questa risposta non appena me lo consentirà. – shigzy

nessun problema, sto imparando personalmente VBA dalla domanda che pubblichi. – Larry

I collegamenti al font e al codice non funzionano più. Qualcuno ha un altro riferimento per il carattere? –

Il codice di Larry è brillante, ma ho trovato solo un piccolo problema. (Avrei commentato la sua risposta ma non ho abbastanza punti reputazione). Stavo avendo problemi quando stavo codificando i doppi zeri. Ad esempio "1200". "00" si traduce in uno spazio. Ci sono numerosi posti nel codice in cui "ritaglia" gli spazi o "sostituisce" gli spazi. Quando proverei a codificare "1200" il codice a barre risultante sarebbe solo "12". Per risolvere questo problema ho rimosso i "trim" applicabili e "sostituisce" come segue. Il codice seguente è solo il modulo di classe. Si prega di fare riferimento al post di Larry per il codice del modulo.
