C# - Dictionary Lookup Efficiency & Request Scoped Global Variable Accessible By Global.asax And Pages/etc?
Feb 8, 2011I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.

Web Forms :: Session Variables Are Accessible To Multiple Users?
Oct 8, 2010I have an asp.net website in which users can submit reports. Another tester and I tested this page at the same time and when I went to review the information I submitted, it displayed information that I didn't submit. It displayed the info submitted from the other user.
I use session variables for these values. I don't understand how this happened? What can I do so each user can individually submit their information without overlapping some one else's information? The plan is for multiple users to be able to use this page to submit their weekly layer reports.
The first example of code is how I add the session variables from the textboxes.

The second one is how I display them in labels on a confirmation page.

Web Forms :: How To Declare A Global Variable That Can Be Used Within A User
May 15, 2010I would like know how to declare a global variable that can be used within a user after the user login and before the user logout across all the possible pages.
I need to develop a web application that will connect to 5 different servers depends on the selection of user on what server they wish to connect and after they select a server and login...I will need to keep track the server name in a variable last until the user logout (user may visit various pages but the server name MUST NOT be changed due to other user login into different server). So how can I do it so that other users may select different servers and will keep the server name for each different users.
Let says:-
User A selects Server A and login and User B selects Server B and login at the same time, so how the global variable can handle the needs for each user (User A & B) with different server select?
Is "Session" the only way to fulfill the above? I think of using Application State but it seems that the value stored will be shared by all users and not for a particular user.

May 14, 2010I'm looking for a way to declare a global variable (so all pages could see) but personal (so if one user puts some value in it, it won't matter to another user or change his value).Sessions and hidden fields won't do. I've tried working with declaring keys in Web.config but unfortunely, the keys values aren't personal, and all users share the same key value.Another way I was thinking was maybe classes, but perhaps there might be an easier solution?

View 4 RepliesWeb Forms :: Global Variables, Menus And Post Back?
Jan 8, 2010with a problem im having or at least give me an idea about which direction i should be going in.I have an asax file - with the following void Session_Start(object sender, EventArgs e)in that I am storing a session which holds a boolean.This boolean holds a flag which when set to true tells the application to go to the database and retrieve data, if its set to false, it checks the information in memory.I am using master pages and inside my master page i have and ascx files - which holds my navigation items(I build the navigation menu based on certain criteria)on a content page (a page that uses the master page) I perform a function when a button is clicked and I set the session flag to truethe problem is that the flag is not being checked until i refresh the page twice and therefore the menu is not updating until the user clicks to another page.my suspicion is that it is because of the page life cycle (the event handlers are done AFTER page load) - is there anyway around this?Is there any web page links you have got that I cant google? (yes i have googled but to little luck - maybe im using the wrong search term).on an additional note im trying to avoid like the plague - storing anything in the viewstate

View 1 RepliesConfiguration :: Network Printer Is Not Accessible In Published Pages?

(means it suppresses the print dialgue box and have information embedded in a file about the printer location). The printer is shared printer and attached to machine which is different from the development machine. Now the printing from this printer works fine during debugging. But when I publish the pages in virtual directory and then executing the application does not print. (pages are also published on the development machine).

In the implementation of my SelectMethod of an ObjectDataSource I'd like to access a global variable set in the PageLoad() event (the method will return just the proper number of items per page).

Javascript - Access Global Variables That Are Set Inside An Event Listener?
Dec 18, 2010I am working with Google maps api V3. I need to get the values of the getSouthWest & getNorthEast bounds of my map. To do this the 'bounds_changed' event needs to be fired in order to get the new values. This is all good, however, I need to access these values from outside the event and passed to a server side function (more specifically, I don't want to call my server side function every time the map bounds are changed).
My code is:
//Global
var sw, nw, Searchbounds;
function myFunc(){
google.maps.event.addListener(map, 'bounds_changed', function() {
Searchbounds = map.getBounds();
sw = Searchbounds.getSouthWest();
ne = Searchbounds.getNorthEast();
});
CallServerSideWebService(sw.lat(), ne.lng(), ne.lat(), ne.lng());
}
When executing this code I get the error message sw is undefined.
Web Forms :: Setting Global Themes To Master Pages?
Jun 28, 2010We have a nested master page which we have made it as a seperate class library.(Becoz many projects use the same master page) Initially we had all our css files,skin files, images inside the Master page project itself. But now we wanted the themes to be global and moved it out to wwwroot as mentioned in the below link.
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/themes/themes.aspx#global
The Masterpage has user controls out of which one user control has the telerik menu. The css is not getting set for that particular user control. We use relative path for setting the style sheet link. But it is not getting set. Its still referring to the old path. But all the skin files, images are pointing to the new global location. Except for the telerik menu rest all is aligned according to the style sheet.
When i do view source, the link to style sheet is pointing to the old location. I dunno why this happening. Is this a telerik issue or i am going wrong somewhere.
