Ciao come faccio a leggere questa

HKEY_CURRENT_USER\Software\IBM\Client Access Express\CurrentVersion\Environments\Collegamenti\A S400\Communication

Chiave User ID

COn getSetting non funziona lui legge solo quello dentro VB and VBA applications ....

Grazie

Dovresti usare le API, del tipo la RegOpenKeyEx e la RegQueryValueEx che trovi definite nel modulo bas sottostante (ti conviene incollarlo nel editor vb per capirci qualcosa) e che penso di aver trovato sui sample del cd di installazione o direttamente nella guida in linea.

Ciao
Buon lavoro

be c'è un altro modo molto più semplice, usando l oggetto WSHshell

vai qui:

ciao

**raffaeu** · 28-09-2004, 08:12

Mama mia aveva preso un colpo !!

Provo con WSHShell che lo uso già in vbs

(ti conviene incollarlo nel editor vb per capirci qualcosa)

la prossima volta usi i tag per formattare il codice che così capisco anche io che devo leggerlo :rollo:

[*code] [*/code] senza gli asterischi

**raffaeu** · 28-09-2004, 13:43

Comunque con WSHshell si puo' fare tutto quello che si riesce a fare con i file vbs ...

esempio per leggere 'qualsiasi cosa'

codice:

oggShell.RegRead(chiave/valore)
oggShell.RegWrite stringa, valore, [tipo]
oggShell.RegDelete stringa, valore, [tipo]

Molto molto bello ...
