View 1 RepliesI have a website of online games and I try to count and show the number of the uniqe visitor per game page, by using Cookies only. (if someone visit after 24hr it will be uniqe visitor too)
the problems is:sometimes (I don't know why), not always, it's update the counter colomn of the game, +2 instead +1, and I don't know why, there isn't any "for loop" etc.. maybe is't because the url rewrite? but it work fine if people enter again the colomn will not update again, the problem is that is update +2 instead +1 (see the code at the bottom)this is my algorithm (something is wrong in this algorithm so don't use it):
1. put the query string in variable (the name of the game) - i'm using url rewite.
2. use this variable for select the game Name (and another information) from the database (and for the cookie I will use the game name from the database and not from the query string to avoid from capital letter problems, because cappital letter for the first word isn't good because words like of, to etc..).
3. for each pageload (there isn't postback in the game page) check if the cookie of the uniqe game exists
4. if not exists, create a cookie for the unique game (the name of the cookie and the his value will be same, because I don't care about it, it's only for check if the cookie exist, and I can't use one cookie for all the games because each time visitor enter the cookie will create for 1 day).
4. after this creation of the cookie try to find if the cookie exist (for cheaking if the user didn't disable the option for cookies)
5. if yes update the database column of the spesific game
the code:
In the end of the page_load - (the GameName is the virable of the name of the game from the database and not from the qury string).

Anyway, I currently have a ajax based progressbar, which works like this: my long-task stores progress in session. Async callback retrieves progress from session, progressbar is updated. Everybody is happy... not! This only works when the "main loop" of the time-consuming task runs in either codebehind or a class with httpcontext. But all my businnes objects cannot do such thing. So, the next natural spet would be to say "move it to a static class" ProgressHelper or something, but since static classes are shared across all appDomain, I would bump into concurrence problems. So, can i have say a "static list progress" say progress["session1_progress"], progress["session2_progress"], progress["sessionN_progress"]? I cannot really see a way to update progress from inside a task in a business object, which i might want to use also in other plattforms like a desktop app?
View 7 Replies I have a page that has a grid view.
The user selects a person from a dropdown list and then clicks a button that adds the users info as
a new row in the grid.
Adding the new row involves doing an insert and rebinding the grid which is a slow process.
How do I use the cache to see the grid update right away?

High level description is this: I have a value that is pulled from a session variable. In the PageLoad method, the value is stored in a local variable. A literal control is set on the page with that local variable and then the value is stored in the database. There is no default value for the literal control on the aspx page. For some reason, the literal is displaying an incorrect value, but the value placed in the database (using the same local variable) is correct.

I have created a user control with a property named CurrentPage. When a link button is clicked it runs PostbackToPage() and passes a command argument in which then sets the CurrentPage property with this new value. On the page which uses the user control I am trying to display the updated CurrentPage property after a postback. When I click the link button to cause the postback the CurrentPage is the default value. However when I click it again it works as expected. So it seems to only work after 2 postbacks. How can I get this to work after the first postback?

which has an update panel ID = up_upload_multiple_files this user control will be placed inside a modalpopupextender. My question is when I click in any button AddFile, RemvFile, Upload there's a postback so the page is reloaded and the modalpopupextender disapears Is there a way to to troubleshoot this?
For error messages, validation faults etc you have
ModelState.AddErrorMessage("Fool!");
But, where do you put success responses like "You successfully transfered alot of money to your ex." + "Your balance is now zero". I still want to set it at the controller level and preferably in key-value way, the same way as errormessages but without invalidating the modelstate.
I am doing a POC of making my website run faster. Currently it stores huge object data in Session while passing information from one page to another. What I was thinking is to use shared methods and properties instead of session. It works, but wanted tocheck if this is an optimum way to do it. Below is the code that does not use session but still pass object data from one page to another:

if save changes are made on control on page1 before save them to db, obviously, these are lost on return from page2 (because are reloaded on pageload from db).How can i save control status between pages round trip?

User Interface: 2 Labels; 1 Buttons
Requirements: Create a Web Page in ASPx that will do the following:
1)One label will provide a count of how many times Button 1 has been clicked in the current session.
2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.

function SendRequest(msg, isBusy, chartMsg, vesselMsg)

if(chartMsg != null)
{
//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
