Re: Get online users count and registered users count ( How wrong is my logic ? #1 )

23-Apr-09 0:33

Hi,

1. Why do you store the user count separately? What is wrong with count(*)? You have to write much more code (possible point of bugs etc.) when you store the count in an extra table.

2. Why do you store the session information within a table? You could use a static dataobject (could be a simple int) within your ASP.NET application. Just increment/decrement the counter whenever a session ends (use Global.asax for this)

3. To update the visible count on your site just query the static dataobject to get the active users. To get all registered users use the sql-query. You could do something like "Store the value for one hour. After one hour ask query the registered users again" You don't need a timer for this, just do it in a master page whenever you get a postback. To update the site you could use a little JavaScript that will force the client to update in an interval.

Hope this helps you a bit.

Sebastian

Thank you for your answer !
My oppinion (I'm not saying it's correct.... it's just what i think) :

1. Assume i have 100 000 users. SELECT COUNT(*) "count every time all the users when that statement is executed". Thats some really big unnecessary weight over the SQL server. I don't think thats the right approach.

2. I think that logic is incorrect. You don't increment and decrement the the online users when the Session_Start and Session_End. Assume that the user closes the browser. The logic fails there - it will actually count that user as online.

3. I think that logic is incorrect. You cannot query the database with that unnecessary logic weight every time there is a postback. That will make a segnificant performance loss.

I store the session info in the database, because it's needed for other purposes too. However i update it every time a user makes a postback and purge the expired data every 10 minutes.

Please give advices.
Best wishes , Hristiyan !

1.+3. Well that's why I said you could store it in a variable that will be update every hour or so...

2. The problem is that you can't get the event if the user closes the browser. What you will get is a session end, when the timeout expires... so the mechanism implemented with the session object (timeout etc.) is the same as you have written by yourself (as you explained in your first message).

Every I/O action takes time. If you have 10.000 users online you will have at approx. 1.000 sql inserts/updates every minute when you update the session data within your sql server. Using a select count(*) every hour seems a blink of an eye to me then.

However , since i've already implemented my logic ( now i'm testing it ), i'm going to ask you in general: Do you strong disagree with my logic ?
Do you see a reasonable point to delete my current implementation and "make it the easy way" ?

If you already implemented it and it is working I wouldn't throw away the logic. But if you encouter any problems at a later point I would think about refactoring.

Hello,
I have an ecommerce website where I have a page named "buynow.aspx". In this page's code behind file, (buynow.aspx.cs) I have referenced many classes which are available in App_Code folder. Also this page calls many classes whose dlls are in Bin folder of the Web application.

Now, I want to accept credit card payments in buynow.aspx page and so I will need to place this page in the httpsdocs folder of my web server. Now, my question is, will I need to create Bin folder, App_Code folder, etc all in the httdocs folder ? Or, is there any smart way so that I can place some information in Web.Config file so that, only buynow.aspx page is treated as SSL page but I dont need to create a duplicate Web application in the httpsdocs folder of my hosting ?

NB:I searched in google about this specific tutorial but did not find any (may be I dont know the right keyword). If you have any article link, please let me know too.

Regards

How to ReFresh a user Control

Vimalsoft(Pty) Ltd22-Apr-09 22:26

22-Apr-09 22:26

i have a userControl and am using it in a aspx page, now i have expose the Following Method that reside in the usercontrol like this

public void load_Again()
{
    string clientscript = "";

    // make available to all subcontrols a variable with the client ID of the textbox in which to store the selected activity IDs
    clientscript = "var txtbxActvClientID = '" + txtbxActvs.ClientID.ToString() + "'; ";
    // assign the current list of selected activities to the list for JavaScript here
    //clientscript += "var ActivityList = String(\"" + txtbxActvs.Text + "\"); ";
    ClientScriptManager cs = Page.ClientScript;
    cs.RegisterClientScriptBlock(this.GetType(), "txtbxlookupid", clientscript, true);
    HighlightSelectedActvs();
}

and am calling it on my aspx page like this

ActivityCtrl1.load_Again();

i have Copied the code you see in the method load_Again() from the page load event of the Control. I want refresh or load the page again after i click a button in my aspx page.

Thank you

use button as asp:button and it will do a postback call where you can do whatever you want.

Is this written on Page_Load of your aspx page?

Yes and declared Public in the User Control

Can you put this code (for LoadAgain()) inside the page load event of user control?
If it is a dynamic user control, it needs to be regenerated on post back of page.

Thanks & Regards,
Nyoti

After the button has been clicked i have Forced a Postback by doing this

response.redirect("Subjectscruct.aspx",false");

and it worked, is this an efficient way ?

Thank you

ajax tab panel validation

If the button is in the page, I am not sure why it was needed to execute Postback forcefully?
Did you try debugging on the page load on the click of button to check if the control comes there?

Thanks,
Nyoti

Hi, I think you must set the properties of your tab panel to autopostback=true

and then in your tabpanel

If tabs.ActiveTabIndex = 1 Then
textbox1.Text = "sayre"
End If

Hope this one can help.

Thanks
