as I said, this is not about Session. Session is just the easiest way
can be used as a storage example at this point. It's about how we
query the server-side viewstate and return the value.
It's difficult for me to post some code here. but the main reason is,
there are many pages in our system dealing with complicated database
entity (parent-children etc.), to improve performance, we place the
entity in ViewState, then use lazy binding to bind child items.
For example, when a user wants to create a new record, open the pages,
a blank entity is created and is placed in the ViewState, then after
fill out all forms (some forms might not have to be opened, in that
case, the child-entity can be null), when the user clicks save, the
program will go through the entity and persist.
say, at the same time, the same user opens another window to search an
existing record on the same page, he opens a few sub-items, so all
opened entities are in the viewstate, other are not (coz it's lazy-
binding), then we are going to have a viewstate conflict, one is brand-
new, another has data from an existing record.
now, the user clicks save to persist the new record. it blows out.
so, single window, our structure works well; in IE6, it's easy to work
around; in tabs, there will be a big issue.
what I am looking for is, find a way to identify the user current
working instance( window or tab), and create another server-side
viewstate entry for that specific page.

And that's exactly what I'm telling you: atomic and idempotent. If you're
talking about ViewState in order to populate controls, the page should never
care which instance it's being used by.
That, or I'm completely, totally misunderstanding you. If you don't have to
worry about competing or racing Session or ViewState values, then why should
the page ever care? If it's populating from the DB, it should, as a
stateless medium, completely self-construct.

The easiest solution, is to highlight the datagrid, press CTRL-C, open
Excel, press CTRL-V.
Add formatting as required, with a pinch of salt.

An easy, nasty way to do it is have a hidden button inside the
updatepanel, then have your button outside the panel simulate a click
on the hidden button.
The hard part is writing Javascript to do that.... Good luck :)

Well that is my issue, I have went through tutorials and videos, I
have added another update panel which updates the time and that seems
to work but the update panel with grid view does not work. I wouldn't
ask for anyone to sort through my "ugly lump of code" if I didn't
research for my self first. I am just wondering if anyone has
experienced this.
Thanks

A Form is an object inherited by the OS. You would have to override
the rendering of the form and write a whole lot of "prettifying
code". It is possible, but almost certainly not worth the effort.
or you could display it as a borderless, title-bar less form and add
pretty borders around the edge.

One final thought, if I change the code to issue an XML Http Request
using JS call from the client, in order to get the data, and then, in
the JS function get the data, and add the items to the dropdown.
Would the items stay there when the form posts back?
Thanks in advance,

One thought. does that mean that if from Javascript I issue a HTTP XML
Request, which returns the data to populate the dropdown, and in the
JS function create and insert the items ('option's) in the dropdown
('select'), and then the user clicks "Save", and the page is posted
back, the items in the dropdown will disappear?
Thanks in advance,

No. How you retrieve data is irrelevant to the situation. What is
relevant is Viewstate.

The FileInfo constructor does not create the file. The file may

there at all. Check if it exists!

Hi Andy,
thanks for your prompt reply. I have the same dilemma and I have asked
the same question myself. However, this is the situation:
1. I have the source code of a project I have been working on. This is
version controlled.
2. In the target directory (output of the build and not setup project)
I have the target also version controlled.
3. After a major or minor release of the software I want to keep under
version control the files being distributed in the setup project. This
is needed so that I know at any given time what source code has been
used to produce the setup files.
Then I thought... ok I could keep the files that the setup project
creates in a separate folder. However, as:
a) the version control (such as subversion) needs an "administrative"
directory in each directory being version controlled and
b) the setup project output is a multi directory structure (setup.msi,
setup.exe, directories with prerequisites)
...I cannot copy all the output of the setup project to a new
location.
The solution I am currently following is to compress the output of the
setup project (and therefore compact it in a single file) and then
copy it in a "distribution" directory which I have under version
control.
The whole process is rather messy and currently very manual. I would
like to be able to avoid to have to write lots of scripts.
Any help would be very appreciated and sorry for the long reply.

Hi,
I am going mad with this. I seem to have what I imagine is a simple
session problem.
You can see the behavior at www.joglab.com where Ive set up the
scenario.
Trying to use a simple login seems to work ok- it writes to the
database:
New user (Choose New 'un)
user:
newuser142205
pass
newuser142205*
...when this user logs in it continues to the default page- which is
the correct continuation behaviour. In the DB the user is shown as
having logged in at that time.
It does not inform user that login is no good.
But the continuation page (default.aspx) shows the user as not logged
in- not showing their user name and showing status as 'login' not
'logout'- login views neither.
I am using the following in in web.config:
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data
Source=HYDROGEN;Initial Catalog=thedb;Integrated Security=false;User
Id=blahuser;Password=blahdeblah;"
providerName="System.Data.SqlClient" />
</connectionStrings>
If I set Integrated Security=true on logging in I get:
Login failed for user ''. The user is not associated with a trusted
SQL Server connection
The Web Site Administration Tool cannot connect to the server from the
local machine- I suspect that this is a wild goose though.
If you dont know the answer to this then perhaps you know a simple way
to disable the non-alphanumeric requirement in passwords which is a
pain in the ass!
I have been following this:
http://weblogs.asp.net/scottgu/archive/2006/12/22/recipe-deploying-a-sql-database-to-a-remote-hosting-environment-part-1.aspx
Any help would be very much appreciated.

Thanks Andrew for your response,
This is the error that I got when I open that specific project -
"One or more projects in the solution could not be loaded for the
following reason(s)
The application for the project is not installed.
These projects will be labeled as unavailable in Solution Explorer.
Expand the project node to show the reason the project could not be
loaded."
Also, project is developed using VB 2005 (It is prerequisite on the
link.) Further document is revised on Nov 2005.
Also I remember one thing that when I was opening the project
developed using VSTO SE on my fresh machine (having VS 2005 / Office
2003 / NO VSTO SE installed), I was having the same errors. Again, I
searched for VSTO on google, but every time I got VSTO SE reference.
And yes, VSTO SE should cover office 2003 and .NET 2.0, that was I
assuming!
Any way, my original question is -----------> "So ultimately anyone
could point me to how can I create task pane in outlook 2003 using
VSTO SE / VB 2005?"
Just now my friend got the answer from Sue (OutlookCode.Com) that
"Outlook 2003 does not natively support custom task panes. You may
want to take a look at the Add-in Express developer library that
frequently advertises at the top of the pages on this site, because it
does offer a task pane solution.
"
So it is not that much easy.... right. Yaa we can do that (if it is
done by Add-in Express developer library), but my boss requires fast
solutions :-( , so here we don;t have that much time to investigate.

TOPIC: Smart Client Performance

We currently have a Smart Client VB.NET (framework 1.1) application
that uses a Web Service to communicate with a .NET assembly on the
server. The data is stored in SQL. The users have a shortcut to the
EXE (located on the server) through an http URL. I understand that on
the first access of the EXE, the components will be downloaded to the
client. On subsequent hits, the version of the assemblies on the
server will be compared to the version of the assemblies on the
client. If the version differs, then the components are downloaded.
As a result, the first hit the load of the application will take
longer because the components are downloaded; however, subsequent
loads should be very quick. Through testing, we have found that the
subsequent loads (where the version has NOT changed and files should
not be downloaded), 1 MB of data is being transferred from the server
to the client. How is this possible?? I would expect very little data
to be moved because the components already exist on the client.
Furthermore, we are struggling with the amount of data that is
transferred whenever data is retrieved from the DB. Here is an
example of our architecture and how much data we retrieve and how much
data is being passed across the network:
Scenario: On the load of a form. The client makes three calls to the
WebService to retrieve data:
The Client calls webService.Function1 (byref dsData as DataSet). The
function returns a dataset with three data tables
dataTable1 - 19 columns 1 row
datatable2 - 8 columns 34 rows
datatable3 - 3 columns 34 rows
Client calls webService.Function2 (byref dsData as DataSet). The
function returns a dataset with 1 data table
Datatable1 - 1 column 6 rows
Client calls webService.Function3 (byref dsData as DataSet). The
function returns a dataset with 1 data table
Datatable1 - 2 columns 9 rows
This process moves about 200K from the server to the client. Is this
reasonable for the amount of data in the datasets??? Does anyone have
an opinion on a reasonable amount of data that should be sent from the
server to the client when retrieving data from the database? Are
datasets too heavy to pass back and forth between the client and the
WebService?
We just finished and installed this application in production and
realized the hit the server was taking and how that hit was affecting
performance. We are starting development on another Smart Client
vb.NET application that is MUCH bigger. If our architecture is
inefficient, then we need to adjust immediately. Any help would be
GREATLY appreciated!!!
Thanks in advance.

First: why 1.1? 2.0 improved SO MANY THINGS over 1.1. I suspect you'd find a
large performance increase simply by going to 2.0 here.
Try to avoid sending large, or large numbers of, datatables/datasets. No,
offhand, it doesn't sound like you're sending too much or too many, but
still, less is better. Prefer data transfer objects instead. There is no
"reasonable" amount stamped on a metal rule somewhere -- it depends on your
architecture, your deployment configuration, and more than anything else,
the pipe between the client and the datasource. What's the client device?
PC, or something handheld? (Assuming PC since you said 1.1 and not 1.0 which
was the pre-2 version of Compact Framework.)
Also, rather than a web service, consider using remoting if your
hardware/deployment/etc. supports it. Even better, consider going to 3.0/3.5
and using WCF and net.tcp
binding.<http://www.infoq.com/articles/scale-with-service-contracts>
As far as your subsequent load issue, what's your Ethernet trace look like?
Is it pulling everything down fresh on you, or is that 1mb "something else"?
Is there some sort of negotiation process going on that's getting choked by
your network configuration? (Just throwing out guesses.)
