Ok, thank you Erel,
Before to post this message I tried with JavaObject but I did not have good results.
I tried with the actual wrapped library Jackcess but the problem that I found is that there is not include a method getColumns() that exists in java.
I tried with
Dim JO as JavaObject
Log(jo.RunMethod("getcolumns",Array As Object("")))
the previous said code gave the error:
java.lang.RuntimeException: Method: getcolumns not found in: anywheresoftware.b4a.objects.JackcessDatabase$JackcessTable
and the next one,
Log(jo.GetField("_columns"))
said:
java.lang.RuntimeException: Field: _columns not found in: anywheresoftware.b4a.objects.JackcessDatabase$JackcessTable
anyone has a similar code where I can do some test I figure out, please.
Thank you
