You can use AJAX to do this, but you'd still be best to impliment a timeout, because if someone turns off their PC, there's literally nothing you can do.

A bit field and a date/time for a timeout is the only way to do this. Storing the Id of the person who has the lock also makes sense ( replace the bit with an int, using 0 for no lock, or a user Id, for example )

Thanks for ur reply.
Storing the id of the user is a good solution, however iam not being able to know when the user leaves the pages of that reference, taking into consideration that this reference has around 25 detail pages and i need to keep locking this reference as long as this user is in one of these pages. My issue is that i am facing timeouts and how can i know when a user eneters a second reference to release the first one and what if he wants to use them both!!!
May be as said there is no one way to do that. I will try to check the query string and if the refId is different i will release the reference. Still i didnt test it.

Corrent. You have to add a timeout because there is no way to be sure that the user has left the page.

how to use xml coment in vbdotnet 1.1

You can use a frame to embedd a HTML page in your app. Or if it's an HTML snippet, you can put an asp:Literal in your page and assign the HTML to it.

Best way to learn asp.net

11-Nov-07 23:06

I don't think VB.NET supports it. You could try the VB forum ( this question has nothing to do with ASP.NET )

ASP.net is a framwork for generating HTML. AJAX is something that javascript supports, and ASP.NET AJAX is a library for AJAX controls that can be added to ASP.NET. I'd recommend the O'Reilly book on ASP.NET, it is a good place to start. Learn ASP.NET first, then understand what AJAX is and what ASP.NET AJAX is, and decide where to go from there.

For ASp.NET 2.0, QuickStart[^] might be the best place to start...

For ASP.NET 1.1, I have a few collection of links..
ASP.NET 1.1 Training Materials for Beginner I used those links when I was training my juniors in my company..

If you are using ASp.NET 2.0, you can use ASP.NET Ajax for developing the ajax-enabled website.. But for ASP.NET 1.1, you may need to use other third-party JS libraries (prototype or jQuery or etc) for developing the ajax-enabled website..

Thanks and Regards,

Well, apart from the ones that you'd get from googling your question, there's the little known fact that .net 2005 came out two years after .net 2003.

I recommend reading the sticky on how to ask questions. Are you even asking about ASP.NET ?

I suspect the guy who answered you is joking, perhaps because what you're asking seems so straightforward. Yes, you can work out the age using DateTime.Now. And the DB gives you the dates to put in the date picker. So, which bit do you need help with ?

matjame11-Nov-07 22:43

11-Nov-07 22:43

Thank you for your kindness.My problem is using the identity number from the database, i.e 840920 5993 081.I want to use this to establish when this person's birthday is.For example if its 841112 5993 081 then I should have a message that this person's birthday is today.And the same for those that celebrate tomorrow.

Thank you so much again.

So you're starting with the person's Id and want to know if just that person has a birthday ? So you want SQL like

select Birthday from person where id='845834534'

you can add a check for if the birthday is today or tomorrow, but you still need to check in code if it's today, or if it's tomorrow, so you may as well do all your checking there. getdate() is how you get today's date in T-SQL. But be careful, if you have a time component to either of the two dates you're checking, they won't be equal. DateDiff may be a better way to go.
