[<gla...@us...>]

Update of /cvsroot/quantproject/QuantProject/b3_Data
In directory sc8-pr-cvs1:/tmp/cvs-serv31680/b3_Data

Modified Files:
	DataProvider.cs 
Log Message:
The GetCloseHistory method has been improved:
if the requested ticker history was not cached yet,
an error happened. Now the ticker is automatically
added to the cached list and the history is read
from the database on the fly.
