Nirosh. That's what we've done. That's why I'm asking the question.

>>I am pretty sure that you are doing some thing wrong here.. can you just
create a seperate type dataset and confirm that it add a connection string
too?? Why it need to have a connection string hradcoded to create a typed
dataset for you.. but it you select the optipon of autocreating the DAL
then yes it does add a hardcoded connection string to the dataset..

>>Thanks Nirosh, but I'm not sure I understood all that.
I'm only talking about a typed DataSet: not about the entire data access
layer - which we code ourselves and which uses many typed datasets. At
least that was the case until now. If typed datasets now have the
connection string hard coded into them, we'll definitely not be using
them any more - for security reasons apart from anything else.

VSS 2005 support auto generating the dataaccess layer .. and in that
case you are free to change the code where it hardcode the connection
string so that it will read it from a config file (obviously you have
to change the code again if you have to create/ edit the dataset again.
In my view point the automatically generated code is very good if you
are heading toward a quick concept demo or a working prototype.. but if
you are looking to develop a real extensible large-scale system, then I
rather advice you to have your own data access layer, indeed you may
have some assistance from the Data access Applcation Blocks or
enterprise library. There you will get that chance of developing a
flexible dataaccess layer.. I am telling this with my experience and if
you go with the auto geneated code you will at times drive in to
bottleneck of your code..

Hi all,
>
This post is sort of tangentially related to my earlier posts on
configurati on files for DLLs.
>
Does anyone know how to create typed DataSets using VS2005's new
DataSet designer, but with the ability to configure the connection
string via a config file? The designer seems to hard-code the
connectio n string into the dataset itself, which just can't be right.
>
The typed DataSets created by VS2005 comes with a dll.config file that
looks as though it's trying to do something like that, and which is
put with the executable at compile time, but altering the connection
string in there doesn't appear to have any effect. We've seen lots of
people asking this question, but haven't found anyone answering it
yet.
