How to implement live update, like stock ticker updates shown in TV .
3  2097 
pkumar,
It depends on the app you are trying to create. Are you trying to
figure out how to draw the scrolling values, or to get the values? The
values you see on TV are fetched from market data, and is constantly updated
(you have one thread updating the buffer with the values, and the UI thread
reads from that buffer).
What is it exactly you are trying to do?

Thanks Nicholas ,
I am looking for the logic for the Updating thread. As soon as the data
is inserted into my database, I want to get the value on my screen. How do I
implement this thread.
thanks in advance

pkumar,
Well, there are two ways you can go about doing this. The first is a
pull method. Basically, you would have a timer, and you would update your
data whenever the timer fires. The second is a push method. You can use
notification services on SQL Server (if that is the database you are using)
to be notified when your data changes. When this happens, you can update
your data store on the client side automatically.
In both cases, make sure you lock access to the data itself, or you will
have problems with corrupt data.

Hello,
About once every two days, I need to update the live/production site with

occasionally I need to update it in the middle of the day where users are

then? I remember reading when I first started learning about asp.net...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
