Timing the events

Hi,
I have an issue related to events. I am new to using events. Hence your inputs will be helpful for my coding.
Code Details: I have two outputs coming in parallel.(For Eg: One output gives Pressure Device list, the other output gives Temperature device). I have created events which trigger when the output for the above is found. The problem I am facing isboth the events execute parallel which is not necessary. Is there a way through which I can time these events to occur one after the other?(Say, first the event triggered due to Pressure must occur, then Temperature). I am sorry that I dont have a code at this moment. I was thinking of implementing this feature in my code. Hence please let me know if this is possible. Also if there is a thread related to this in forum please let me know.
Thanks a lot for your inputs.

Can I use flat sequence structure in this case?

Why do iCal timed events have date written in in the event?

iCal. If I add an event ("New Event") that is an timed event (does not happen with "all day" events) it has the date of the event after the time.
for instance, a meeting at 8:00 AM on 9/10/08 reads "8:00 AM9/10/08 Meeting".

That makes no sense since it is on the calendar IN THAT DATE. My other 2 computers iCal doesn't do this and they are synced.
I have no idea how to get rid of this?

I have a question about the calendar on the ipad2. I have multiple calendars in different colors. Some of the events are filled in with color. Others are just listed with a colored dot in front of the event. Any ideas why events ar showing up differently?

I have an ipad2 and my question is about the calendar. I set up multiple calendars with different colors. Some of the events show up in filled color. Others only show with a colored dot in front of the event. I can't figure out why some show up one way and others show up differently? Any thoughts?

On mine the ones that show on a coloured background are all-day events, the ones with dots and just timed events.

When adding event in iCal, the event becomes full-day by default. How to change?

Also, when de-clicking full-day the events becomes timed 10am-6pm. When changing start time, the end time follows with this 6 hr gap. Not the worst problem to deal with in this world, but...still. Any way of changing this little detail? I.e. to be able to double click the desired day, getting an event that starts with the current time and a 1 hr gap (as with the old version of iCal, that is).
Cheers

How to control the event structure

What i am trying to do is when the condtion is true, i want the event structure to excute. But event structure wil not excute unless there the puch pattern changed, any idea how to do that ?

It's more likely he wants the sequence of events he has put together to run after the result changes once. If you change the logic to check the values after each change of numeric(2), he'll need to learn to check to ensure the last iteration wasn't already true. Otherwise, he's going to start the sequence over and over.
Really, you need to get away from the event structure entirely. It's not what you want. Your code lends itself to a state machine very well.
You'll want to ask yourself a few things:
1) Do I want my code to run continuously or do I just want to check the two numerics once? (your code currently does the second)
2) Do I want the user to be able to stop my code once the sequence starts? (this is generally a yes)
3) Do I want Path 6, Path 5, or the comparison to happen first? Do I want them all to run simultaneously? Do I need one before another? (currently you cannot predict which will happen first.)
Topics you'll need to understand are: state machines, data flow, case structures, timing, and race conditions. Right now, you're looking to get yourself into trouble.

CPU TIME and DB CPU events under TOP 5 TIMED FOREGROUND EVENTS section in AWR report

Is there any difference between "CPU TIME" event and "DB CPU" event when shown in AWR report under section "TOP 5 TIMED FOREGROUND EVENTS"?
As per my understanding of both these terms they indicate the same thing. But then if it is so then why have different names?
I searched around but the only relevant discussion that I found was as under, which didn't really cleared the doubt.
https://forums.oracle.com/message/2571255#2571255

In the article that you have mentioned - Jonathan Lewis gives you a very clear explanation. CPU Time is updated at the end of a query. DB CPU is updated every few seconds.
So the CPU Time may be less than DB CPU if there is a long running query that did not complete during the snapshot that you are reporting for. Conversly CPU Time may be larger than DB CPU if there is a long running query that spanned multiple snapshots but completed in the snapshot that you are reporting for.

Differences between "top 5 timed events" and "Top 5 Timed Foreground Events

Dear all,
i want to know what is the difference between "top 5 timed events" and "Top 5 Timed Foreground Events" in AWR reports

User I/O Wait class in Top 5 Timed Foreground Events

Hi Mates
In my awr report in Top 5 Timed Foreground Events, i get the below event list
Event     Waits     Time(s)     Avg wait (ms)     % DB time     Wait Class
DB CPU          25,721          58.29
db file sequential read     67,491,952     7,710     0     17.47     User I/O
db file scattered read     7,147,112     2,560     0     5.8     User I/O
log file sync     2,926,748     1,526     1     3.46     Commit
direct path read     342,745     834     2     1.89     User I/O
So does it means that there is a issue with disk I/O on my box. since the wait class is showing as User I/O.
I am running the single instance database with oracle version 11.2 on IBM AIX server.

If so then take a look at Dom Brooks comment - your average read times are in the range of 0.1 to 0.3 milliseconds - they're mostly coming out of filesystem cache (but maybe you have some very good database flashcache installed).
Your first move should probably be to take some of the memory from your file system cache and increase your buffer cache - this will probably decrease the number of reads reported and the amount of CPU used. I'd also look for statements that seem to be doing an unreasonable amount of I/O to get their end results, and check the "Segments by ... " section of the report to see which objects are seeing most I/O.
Before you mess about with ASM, you should simply check for easy ways to do less work.

Some frontpanel controls stop firing the Event Structure

In my main vi,I have an event structure. I created a subVI that also has an event structure. I load the subvi via a subpanel in my main vi. It runs fine for a while. But sometimes after firing events on the subpanel, most but Not All controls on the main VI stop firing the Main Vi's event structure. The Subpanel's subvi event structure always works fine. When I reload the program it works fine again for a while.

This is the problem that's been bothering me too (big time actually). Thanks for the insight!
First of all I love the event structure and it totally changed the way I program labview. Together with the subpanel addition, it makes for very professional looking programs. Here's my version of the same problem:
I have an event structure on the main VI, and ~20 subpanels. I load various subvi's in the subpanel of the main VI as required. Each subvi has an event structure to handle GUI and incoming user events. I found the problem in the full blown operation, but the problem also appears when I only have one subpanel running, so only one event structure in a subpanel and one event structure in the main program.
I had the problem with a mouse down on a table, and with a doubleclick on a listbox. And indeed I had an attribute node (reference + property node in my case) to the listbox in the event case that handles the doubleclick. When removing the attribute node, no more buttons will stop to respond on the main panel. When you try to readout or access the listbox in any way in the event case that handles the double-click, it fails. It does not matter whether the "Lock front panel until the case for this event is completed" is true or false. After it fails, you have to unload all the code and reload before LV is able to see some of the buttons on the main panel again (LV7.1.1). You do not have to close LV just the VI's.
So my first work-around after reading your story was to drive a user event from the doubleclick event case. That user event case then does the stuff I want to do with the listbox. Did not work. I then added a delay of 1000 ms before accessing the attribute node in the other event case, that worked. I then moved all my stuff back into the original event case and added a delay there before accessing the listbox. 100 ms failed, 500 ms works. So at this point I would tend to unexpected behavior from LV which is timing dependent, not "Operator error".
There is never a problem in any of the ~200 events in the ~20 subpanels. It is always the main panel that is affected. The event handler simply does not "see" some buttons anymore (value change), for example the "mouse down" event would still work for a boolean buttton on the main panel whereas the "value change event" would consistently fail.

Hoping for some help with a very frustrating issue!
I have been syncing calendar and contacts on my iPhone 5 and Outlook 2007 using iCloud 2.1.3 (my PC is running Vista). All was well until the events I entered on the phone were showing up in Outlook, but not the other way around. I’ve tried the usual recommended steps: deselecting calendar and contacts in the iCloud control panel and then re-selecting, signing out of the panel and back in, and repairing the Outlook installation in control panel. I even uninstalled iCloud on the PC and downloaded it again (same version).
The furthest I’ve gotten is step 2 (and once, step 3) of 7 while performing “Outlook Setup For iCloud.” At that point I get, “Your setup couldn’t be started because of an unexpected error.” After the first attempt at all this, all my calendar events disappeared from Outlook, although they are still in iCloud calendar and on my phone.
Sound familiar? Any ideas on how to solve this iCloud/Outlook issue? Thanks much in advance!

How can I change the event display in an APEX 4.2 calendar?

Colleagues: The APEX calendar feature is pretty neat, but of course there's a feature I'd like to use but can't find how/where to change it. In other calendaring apps (e.g., Thunderbird) when an event is logged, like tomorrow's staff meeting, the time is blocked out vertically for the length of the event. So for example: if staff is from 2pm-4pm, both 2-3 and 3-4 are colorized so a quick visual will show what times during the day are not available.
The APEX calendar will show a colored bar for the start time of the event, but not a blocked-out vertical for the entire event. Make sense? Any way I can change the calendar/event view to accommodate this?
Thanks for your help.

I have a HP LaserJet M4555h MFP, how do I know if my firmware is corrupt, is it in the event log?

Model of MFP = HP LaserJet M4555h MFP = CE738A
With fax accessory for HP LaserJet MFP Analog 500 = CE737A
Firmware Datecode = 20120623
Firmware Revision = 2200643_228339
The inital issue was receiving faxes, so I updated the firmware to the above listed. In the event log it shows since the firmware was updated on Nov 7th the following:
The device keeps prompting to restart the printer.... I haven't been able to screen capture the message off the device yet... on the Information tab through the EWS it's shown: "An unexpected error occurred. We apologize for the inconvenience. Please try again." What is that suppose to mean?
Faxing has stopped working completely....
Can you tell me if this means the firmware is corrupt and show be re-loaded?
Or suggest what my next steps would be?
Anything is helpful...Thanks HP Seeker.

Hello, you can also try a partial clean and reload the latest firmware, see if that will work.

How do I add web part in the event receiver after the site is provisioned in SP 2010?

How do I add web part in the event receiver after the site is provisioned in SP 2010?

You try the below steps:
1. Use long operation to provision the site, so that it does not time out in process.
2. After provisioning, you can add a page or add the web part directly to landing page of site.
For each of the above steps you can find the sample code pieces.
if you couldn't get that, let me know. I will share with you.
Thanks, Ashish If my response has helped you, please mark as answer.
