I've been asked to display some meter data on the web and I need preliminary
advice.
We have several hundred meters on site, with a system that writes out xml
files at 10 second intervals containing their data. (These files are
overwritten every 10 seconds, not appended to.)
First, I need to display two numeric pieces of this data just as numbers in
a web page. Naturally that's easy enough: where I'm stumped is REFRESHING
that data when it's updated every 10 seconds. Of course I don't want to
refresh the whole page, but only update a particular number when its
associated xml file is updated.
I've seen this done client side with javascript, but it was pretty cludgey.
Can ASP.NET help me here with a kind of persistant connection to these xml
files? (I thought the DataSet did such business out of the box, but it
doesn't as far as I can tell.)
Second, I need to use this data later for graphic trend displays. In other
words, I need to show in graph or chart form how each of these meters is
performing over time. Since the xml files are overwritten, I obviously have
to persist each piece of data somehow. I can think of any number of ways to
do this, but none of them seem too elegant. Any advice anyone might have
will help me think this through. 0 906 This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

We have an MIS system which has approx 100 reports. Each of these
reports can take up to several minutes to run due to the complexity of
the queries (hundreds of lines each in most cases). Each report can be
run by many users, so in effect we have a slow system.
I want to seperate the complex part of the queries into a process that
is generated each night. Then the reports will only have to query
pre-formatted data with minimal...

Many Access Users fail to realize that it has a built-in Progress Meter that can display the relative completion percentage of various processes. It is fairly limited, but nonetheless, does provide visual feedback indicating the percent completion of a certain task. The Meter itself, when activated, rests on the left hand corner of the Status Bar and is controlled via the SysCmd() Method. It is straightforward, simple to use, and involves only...

Hello everyone.
I am working on a Password Strength Meter and I am running into 1 problem that I would like to fix.
When pressing the "Clear Password & Try Again" button, the password clears out of the text box, but the meter will stay at its current position until text is entered back into the textbox. Once text is re-entered, the meter will display the results again. I would like everything to reset when the button is pushed, but I...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

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,...
