I'm still unable to reproduce the issue. Is an exception being caught by
this
method while trying to close the data reader? Also, perhaps instead of
using
the IsNothing function, you might want to change the "If" expression to:
If Not Dati Is Nothing Then
In theory, changing the "If" expression should not make any difference;
however,
I seem to recall that the IsNothing function was typically used for checking
the
sub-type of a Variant (i.e. and not for checking for null references). Of
course,
I have not used Visual Basic.NET for quite a long time and I may be wrong.
