Hi, On a site where users log in with username and password. How do I force a logout event to run before the application closes OR BROWSER IS CLOSED? I know about session_end, but that doesnt help when the browser is just closed! I really need to run an event to do a DB query before a user loggs out! Please help.

Regards,

Tintin

Not sure got your clue...
But if you just want to close the user session, just simple call Session.Abandon()...

There is not sure way to do that.

You can catch the onunload event in the browser, and open a new window that will run a page where you can do your database work. Of course that doesn't work if Javascript is disabled in the browser, or if a popup blocker stops the window.

Unless the browser tells the server that it's closing, there is no way that the server can know when the browser closes. The closest thing that you can get is to have the web page send requests to the server at a certain interval, so that the server can detect when there are not coming any request any more.

You are confusing client side scripting with server side scripting. Your script is running on the server, but the button click event is occuring on the client, as you have not defined the submit button as runat="server"

You just create a new web page in Visual Studio, drag-drop a button on the page. And double-click on that button, now you can put your code in the button event handler...

You have excluded most of the error message, so most of the information is missing, like if it's a compile time or runtime error, and where it occurs.

I can't see that you are using "SubmitBtn_click" anywhere in your code, only "SubmitBtn_Click".

What was the error returned?
ds.Tables[0].Columns[0].ColumnName should work unless your dataset is null or contains no tables, or the table has no columns at all.

BTW, why are you using alert? If you mean to access the dataset from Javascript, you need to convert the dataset into either an XML or Javascript array first.
