Here i m just providing logic. I think this may be helpful to you.
Steps :
1. Declare a PWDCheck function which will recive username and pwd as an arguments.
2. Function will check the username and pwd against database userDetails table.
3. You have to declare a static variable, and increment the value of that variable, when pwd is invalid.
4. For locking the users a/c. In database, UserDetails table we should have a status variable for storing locking status.
5. If the value of the variable reaches to 3 then you update userdetails status variable to true.

How can u get server side ontextchanged event like in windows application ? ASP.NET web application. It need a post back to call events. So make autopostback property of textbox to true which will make postback automatically.
If you want to do this without posting back form, use javascript

Hi All,
I'm facing a problem with the page postback.
Its like....I have a treeview control whose first three levels are populating on page load. The next levels are being populated on “treeview_treenodeexpanded” event ,based on certain criteria .But each time we expand it the page gets posted back, as it is the case. I want the postback to be blocked somehow and the tree nodes need to be populated on expand event only.
Is AJAX a solution for this? If so, how to implement this?
I hope someone can help me out with this.
Thanks in advance.
Regards,
Jeeva

The “treeview_treenodeexpanded” event is server-side so therefor a postback is required for this event to fire.
The treeview has a built in Ajax-style feature that populates child nodes without a postback. To use it you have to set the PopulateOnDemand property of nodes to true.
However this will only work with the TreeNodePopulate event, not TreeNodeExpanded. You would have to change the populating code to use that event instead.

how to create pdf file using ASP.Net without third party tools or components?
Nithya
|
|
|
|
|
use crystal report. you can export crystal reports datasource to pdf
|
|
|
|
|
You can't without a component at the moment. One way around it may be to use the Office 2K7 object model (but that's still a separate component)

Hi Friends,
I am developing a website to watch online movies. User needs to call a number to view movie (A company provide service to check whether user is connected to line or not They will call a script that will save or delete record in the database when user connects or disconnects phone line).
The only think which I need is that I need to run a script that checks database after every 5 or 10 seconds whether user record exists or not. I know it is possible to 'Refresh' page after certain time but my client doesn't want to do like this. I am using (c# or vb.net) and Access database for this. I am struggling in it so waiting desperately for your reply.
Regards,
Abubakar Malik

use XMLHTTP Request and response in javascript. Send asynchronous request and get the response. Prnt the value where u want to
|
|
|
|
|
It will be really nice if you give me some code for that.

Would you please stop asking the same question over and over and over and over and over again, at least until you have read the replies that you already have gotten.

You can simply use an AJAX timer that manage the hidden postbacks that check if the record exist, interrupts the video.
AJAX timer is a component of Microsoft AJAX framework (Atlas) and it's completely freeware.
