OK, so I have a dll, which is my data layer and it has a connection string property in a .settings file. In my web.config, I see this:
<applicationSettings>
<DataLayer.Properties.Settings>
<setting name="ConnectionString" serializeAs="String">
<value>
Data Source=xxxx;Initial Catalog=xxx;User ID=xxx;Password=xxx
</value>
</setting>
</DataLayer.Properties.Settings>
</applicationSettings>
Now here's the rub. If I change the setting in my web.config file, the code doesn't use that value, it uses the value inside the dll. How, from my dll, do I gain access to the value that's in the web.config ?

I had to add the values in the appconfig section and read from there, it seems that ASP.NET copies the values out of the dlls into the web.config, but the dll doesn't look back there to update the values.

I want to provide a feature that allows the user to dynamically change a theme using ajax, similar to what's going on at MyYahoo.com (Go to myyahoo.com, click "Change Apperance" in the middle of the page, then choose a different color from the menu. You'll notice the background changes without a refresh.).
I know how to change themes WITH a page refresh, however I don't know how to do it without one using ajax. How could I do this?
Thanks.

I have a problem deploying a web part to a production server that does not manifest itself on my test server.
The web part in question uses Microsoft Office Interop to perform routine procedures on Word documents like calculating table of contents, imposing project standard templates, etc.
When I execute this web part on my test server it does the desired operations to the selected document(s). When I deployed the web part to a production server the initial selection controls come up and I am able to navigate to any repository or subfolder on the server. When I select document(s) for processing and click on a process button I get a 403 browser error.
HTTP Error 403 - Forbidden
Internet Explorer
When I look in the SharePoint server log I see the following error.
08/11/2008 11:50:14.88 mssdmn.exe (0x14E8) 0x1560 359 0 Monitorable CHttpAccessorHelper::InitRequestInternal - unexpected status (401) on request for 'http://server_name/project/test_document.doc'. - File :\office\source\search\search\gather\protocols\http\httpacchelper.cxx Line:467
The D drive (smiley face in the above error message) is a DVD drive on the server but the log entry seems to indicate that an office program is executing there.
If anyone is familiar with this type of behavior could you please tell me how to resolve this problem?

Hi,
I'm new to asp.net and have a question regarding the viewstate:
I have an editable datagrid with dropdown list on several columns.
My co-worker warns me to be careful about the size of the viewstate, which is a good advice. However, I'm not quite convinced by the way he did the match.
Assume that there are 5 coumns in the datagrid and each column is edited with a dropdown list, and assume there are 100 rows
5 dropdowns
10 items in each dropdown
30 chars for each dropdown item
100 rows in the grid
Also assume that all controls are ViewState enabled.
My co-worker said that the ViewState will include everyhing in the regular Grid, plus
5 x 10 x 30 x 100 (i.e., the dropdown's view state is repeated for every row, that's the same as 100 dropdowns in each column). Obviously, the ViewState will grow dramatically it that's the case.
But my initial thought was, if only one row is ediable at a time, the postback should inlcude only 5x10x30, puls the regular grid data.
Can anyone clarify this?
Thanks in advance.

Yes ViewState is going to increase in the Page

Is some what confusing don't know exact algorith to have viewState
I think it will create optimized one.But not sure
Andyz50 wrote: But my initial thought was, if only one row is ediable at a time, the postback should inlcude only 5x10x30, puls the regular grid data
Ya this can be one is one of the solutions
other solution can be instead of showing 100 rows at a time,use Paging and show 10 to 15 or similar on each page.
Thanks and Regards

Hi All,
I need to write a module to log all queries ran on a page. Once the page is loaded, limited users can pull this information with a click on client side to see.
- This log should not be stored anywhere but in memory, which means the scope of this information is only the native page.
Does anybody have any idea how this can be achieved?
Any idea will be appreciated.

What kinda query? Do you mean operation like search etc...
peacefulmember wrote: Once the page is loaded, limited users can pull this information with a click on client side to see.
Its upto you weather you want a client click or server click
As far as limited users are concerned, check for the permissions of the user.
But as the information is at server, you need to make a server call.

By queries I meant all the queries excuted to render one page. In my aplication one page is generated with multiple queries. Thus, I want user to click on a button (which I have on every page) and then see all the queries executed to build that page.
I am not clear how a server call can help? These queries are neither stored on the database side nor I want to save it in a file or in database. I would like to achieve this by keeping it in memory or stream etc.
I was thinking on either saving the sqls in javascript or was also thinking on lines of TraceListener. I am just not sure how? Anybody has better approach, please suggest with a solution.
Thanks

I'm trying to add spam and abuse reporting functionality to my app, I basically have a link with the text 'Report this post' that should be changed to 'Thank you' when clicked by the user, it should call a page in my app (silently) and send it the post id. I find ASP.NET Ajax too much for this very simple scenario, I have no server controls, it's just a link (I'm not an expert in Ajax but I read a little about UpdatePanel and didn't like it very much esp. the complete postback part, Page_Load .. etc). Any suggestions how this can be done without ASP.NET Ajax? Thanks
Regards

ASP.NET AJAX just wraps the java script code into built-in controls. You can always write simple JS code that does AJAX call. Check this[^]

I have a weird session problem that seems to only happen in firefox and safari but not in IE.
Basically when the user logs in, the sessions are created. The weird part is, if they select the products page the session is lost in firefox but not in works in IE. It seems to be just this page that losses the sessions variables in firefox. If i stay within the logged in account section, and view my profile, orders, etc the session stays in tact.
Any suggestion or ideas that would cause this issue? I am using master templates, and the session state is InProc.

Intresting i never heard such issue with browser,
We can have issues like UI,CSS or client side scripts but the sessions are going to store at server side, How come browsers can affect State management at server side ?
Let me know the fix for this issue, whenever you fixed it 
Thanks and Regards

Hi,
I currently have a series of user controls on a page which individually have their own validation controls and summarys. However when the client side validation occurs on a control that is towards the bottom of the page, the page then scrolls to the top, even though the validation summary is displaying the messages at the top of the user control back at the bottom of the page.
Is there anyway to prevent this scrolling from occuring as it will obviously confuse the users somewhat!
Thanks

We have viewstate enabled at present, this would not affect my problem as the page has not posted back at this point as the validation occurs client side.
Thanks for the suggestion though

If you set:
ShowMessagebox = true
Showsummary = false
The page wont scroll to the top

At the site Casa.Sapo.pt we use Resource files to store texts for internationalization (one with the portuguese texts and another with the english texts) and we are considering using a HashTable, a Dictionary or a class directly containing strings.
In the first performance tests, i simply accessed the text's references into a String reference. The results were these:
- Resources: 1238 ms
- HashTable: 1910 ms
- Dictionary: 1968 ms
- Class of Strings: 12 ms
As expected, all took 100+ times more time to access the strings than the class with the Strings. But in here came the first strange result. The HashTable performed better than the Dictionary, which i find extremely strange.
Then, i tested loading user controls which access strings (a combination of inline accesses "<%%>", using ASP:Literal.Text and others). Now came the really strange results:
- Resources: 150 ms
- HashTable: 146 ms
- Dictionary: 256 ms
- Class of Strings: 227 ms
Everything is completely «wrong»... User controls accessing the class of String (by a long far the fastest) now is one of the slowest??? The HashTable performs better than all the rest??? The Dictionary, that should be faster than the HashTable, is the exact oposite, it is the slowest!?
Can anyone try to explain these strange results? I can't seem to make any conclusion out of these results because i don't understand what is happening to give such strange results and i am left clueless as to if i can really substitute the usage of Resource files to handle internationalization.
Windows is just as secure as Linux (when shielded with a Firewall, Anti-Virus, Anti-Spyware and disconnected from the Internet). Windows has even better performance than Linux (when running without Firewall, Anti-Virus and Anti-Spywayre).

Are you saying DropDownList ?
aspdotnetuser wrote: now i would like to call javascript function on selected index change and value store in variable
Yes you can do it just have a javascript function which will get called on OnChange Event of drop down
Register it
mDrpCounties.Attributes.Add("onchange", "JavascriptFunctionName();")
If you want to have selected value at the server side use Hidden Varaibles for that
Thanks and Regards
