Thanks for answer Joe, but as just sayed i have only one datareader,
That is not possible. There must be at least two different data reader
instances because the references in the watch window did not match.
Every time you call ExecuteReader, a brand new data reader is returned.
Keeping track of these returned data readers is very important because
they must all be properly disposed at some point.
i'm sure of that, and this is demostrated because with others provider
i have not error.
Perhaps the other providers do not have a restriction on resetting the
underlying connection for a command when data readers are active.

Hello Joe, i forgot to tell you what to do for see the error....when
checklist appear, click on ANNULLA button...after somes cicles it will
appear...
I know what you say, but you have all code wich is involved in the
error... for the parte involved, no other function was called... i call
executereader only for one datareader and two only times directly to the
command... do you found the other datareader in the sent code? If exist
it have to be in the sent code, but i don't see nothing.. you could?
