Query: refresh the list item in a list box on a time interval.

1 New Member
Hi all,

I'm a newbie in .Net programming. I'm developing a web application that has a listbox containing more than 1000++ items. This listbox is dynamic as the content will change on a time interval (e.g every 5 seconds). I tried to compare the list items and make a change if there is a need using for loop and if condition. I even tried using ajax. But then, when i get the data pass back from ajax function, i also need to made comparison. As the items are huge in amount, it cost some delay (quite significant) in my application. Is there a way for me to repopulate the "large" listbox?

Regards,
achio.

I have a table with a few million rows of temperature data keyed by timestamp. I want to group these rows by timestamp intervals (e.g. every 32 seconds), compute aggregate functions on the columns, and ultimately feed the result into a graph-drawing web thingy. I'm trying a few different ways to get what seems to be the same data, and seeing some odd behavior from the query planner. The table looks like this:

I do not have the experience with it. For example, update the data in the ASP form every minute by retrieving data from database. Or do you have other methods? Thank you for any advice and information about it. David

I tried to put an "on error" statement in a routine and got the message that I cannot user "on error" and a lamda or query expression in the same routine. Help does not list anything useful for explaining a "lamda" expression and so I don't know what one is and I am not doing any database stuff in the entire program. So what does this error message really mean and what can I do to get an On Error into the routine?

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
