Hi Everyone,
I am using a web part in a page for the first time.To try how it works i did in a sample page where i first added a webpart manager and a webzone with a label control with some text.
When i try to run i get a run time error saying
"When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
I dont have sql server in my local machine but should it be needed.I am not trying to connect to database. Then why i couldnt run.
Kindly clarify me

Hi,
In my web application i want to maintain list of number of user is online.
If one of them close browser without sign out then he/she will not be displayed in list.
And also i want to restrict multiple login by one user in different browser.

You can do this with AJAX. Otherwise, you have to wait for their session to time out.

Easy, have an 'is logged in' property on the user table, if they are logged in, either log out the old session ( better ), or refuse login.

Is it a good practice on believing javascript for this ? In a worst case scenario, what will happen if user system got hanged and need a restart ? So the flag there in user table still show he is online, and prevents him from logging again.
I think there is no efficient methods for this. What do you say ?

If system is hanged, now he/or she has shutdown system,
now he/she wants to login once again then.
how do i change flag,

Well, AJAX is the only way you can find out if the browser was closed. It's wise to add code to manually clear sessions you know have timed out, also, if you must do this at all.

That's the main reason that I said it's better to kill the old session and allow a new login to take precedence.

Yes, it's messy, no matter how you look at it.

Yes it is.
It's not possible to believe on session_end also, which won't be fired all time, and it's specific for InProc.
I have seen some examples which explains this in much more efficient way by making use of cache. Cache timeout will be set as session timeout time and assign a callback function when cache timed out. Inside this function we will be able to update the flag.
This looks much closer to the problem. ?

With AJAX, you can capture a client side event when the browser is closed, and send a message to the server. That's what I was referring to. But, it's still messy. Turn the power off, that's the obvious example that you cannot code for.

Hi, Thanks for Reply
Can I check that current session_id is live or dead.
If i get that then i can compare it with session id stored in database,
if it is still live then i can restrict user from login.

Many times answered for the same question by different people. Try doing a serch on this discussion board.

To maintain online users, you should go with database. On closing browser using javascript onUnload event check the window size and if less than or equal to zero update the logout flag in database as false thru AJAX. On every time login show the online users with that flag as true.
Be simple and Be sample.

Hi,
My application requirement is that i need to navigate from Page1 to Page2 and from Page2 to Page3 Or directly from Page1 to Page3. For transferring from Page1 to Page2 i am passing the following page path in Server.Transfer "GridCollection/GridPages/GenDGSelect.aspx", this works fine. But when we transfer from Page2 to Page3 we pass the following path "GridCollection/GridPages/GenDG.aspx" we get the error "Error executing child request ...". The path is proper and ideally it should work.
Surprisingly when i navigate from Page1 To Page3 using the above mentioned path it works fine.
Also when i change the path of Page3 to "../GridCollection/GridPages/GenDG.aspx", transfer from Page2 to Page3 works fine but the same fails while transferring from Page1.
I am totally confused out here, please help me out.
Thanks,
Anees

Your paths are relative. Start them with a ~ and make sure you specify the path from the root. The .. works because you're specifying a step up, the control that renders this is in a subfolder, obviously.

Have you set EnableViewStateMac=true on page3 ?
One more thing to consider when using Server.Transfer is, when you transfer from page1 to page2, URL in the address bar will remain as page1. But when you transfer again from page2 to page3, then your URL will be changed to page2. This is how Server.Transfer works.

Don't know exactly you can do this, try Page.Control.Add(UserControl). But why you need this ? In a custom controls all the HTML tags are written manually in the Render() method. So I don't think that you can use the user control.
Why don't you implement the usercontrol functionality in your custom control instead of adding it ?
|
|
|
|

If the functionality is readily available then why should write that again ?
Any way i think i will have to add that functionality now .
Again one question can i add asp.net controls to custom control ? 
Thanks and Regards

You should look in to the ASP.NET control rendering. When rendering each control, Render() method will be executed. So you can write only HTML elements to the response using HtmlTextWriter object available on the overided method. Whatever ASPX tags you wrote inside this will be displayed on the page without rendering.
You can create object for the ASP.NET controls and write their rendered HTML to the Response instead of writing the tag.
Hope you are clear
