Counter to generate event after certain counts

Hi everyone,
I would like to use my PXI card to generate an event (to my software) every say, 100 counts(for 100kHz Timebase). In other words, is it possible to generate an event every 1 ms based on the counts on the counters.
Also, is it possible to reset this counter based on the GPS 1 PPS? I wanted to sync this counter with the incoming GPS PPS. Thanks!
Regards,
YB

Hello,
It is possible to reset a counter using a boolean input. If you could convert you GPS PPS signal to a boolean array, this idea applies. I'm linking a knowledgebase article that demonstrates how to reset a counter. It should be very useful in getting you started.

Generating events after jaxb unmarshling

Hye,
I have a an application that uses a request-response model. I have generated code for my schema. I thought this would free me from the hassle of SAX parsing where I have to write the whole parser. But in SAX atleast I know and specify, that at every occourence of a certain element what actions I must take. So therefore the jaxb concept confuses me. I unmarhsal my xml reponse and then i traverse the entire java xml content tree to see what I get. I am not aware of DOM as I havent used it actually, (but I will read into it after this email) but then does jaxb classes mean that after unmarshalling content, I go about and check the whole content tree for what response I got and what actions must I take. A root element can have a number of other actions elements and I need to identify which one was given (maybe by doing isInstanceOf() of or isSetXXX() on all objects to see what subelement I got). Do I have the right concept. I havent gotten deep into the project but I wanted to clear this before I make this descision final.
Can someone point me out to the finer concepts of jaxb binding and usuage, any article link, code example on how to use it to full advantage would be nice. The tutorial does not cover this point appropriately I feel. Just the basics.
Regards.

hi!
i could not found the .addActionListener(this) where are you adding the listener?

Generate event

Hi All,
I am using Labview7.0 and need to generate automatic event. It means without any button press or mouse move activity on front panel, i want to generate event after every particular time interval.
How i can fullfill my requirement??

Solved!
Go to Solution.

Hi Ratna,
Dynamic event registration gives you increased flexibility in controlling how and where events are handled in your application. You can try the attachment. It should open in LV 7.0.

Collector Rule stays with the same Description after "fast" generated Events - (Custom MP)

Hi , I have a problem to customize one management pack
I use this MP for a reference
http://windowsmasher.wordpress.com/2011/02/07/monitoring-esxi-syslogs-with-opsmgr-2007-r2/
The problem is when I generate event (they are syslog events) the description Data is all the same for some time :)
For example if I generate 10 events fast , the description is all the same , but the data inside is different. MP should take XML element with Powershell script and it's working fine for a "slow" published events.
I don't know why only the description data is the same . I tried to modify the script to NULL the $bag variable and $xmlMessage but without any luck.
Any help will be appreciated
I'm trying to build SYSLOG parser to visualize my data and eventually to do some reports.

Still having a problem? Can you explain a little more what the issue is? Are you saying the event collection provider does not work correctly when there is a burst of events matching your criteria?

Generate Events based on Cache size

Hi,
I have a use case where I need to generate events when the size of the cache has reached a specific value. The cache will be highly transactions (lot of inserts and deletes totaling to 6 million transactions per day). Also, I cannot limit the size of the cache as I don't want any data to be lost (trying to insert when cache size has reached its limit).
One of the ways I could do this is to use a MapListener to generate an event on every insert to the Cache, and then check for size each time to decide if the further processing needs to be done. With the nature of the traffic in the cache, the items in the cache are to be processed when the size threshold is reached and then deleted. But, I'm not sure how much of an overhead these events and listeners will have (with 6 million items going through the cache each day)
Is there any other more efficient way to do this? I have looked at Continuous Query cache which uses a filter based on a cache. But, I'm not able to figure out a way to get the size of the cache using a filter.
Any pointers are helpful
Thanks in advance
Regards
Vikas

Hi Vikas,
Typically a size type calculation is the cumulative result of all storage enabled nodes, i.e. a Count aggregation. In your use case you want to be made aware of changes to an aggregation but as an aggregation is point in time of request opposed to continually being updated it does not fit your use case. One option is to create a MapEventTransformer that you register with the cache which increments a counters cache (on a separate service) using an EntryProcessor, i.e.

How to get String after Certain Number of particular characters

I want to get character after certain numbers's of particular character.
For example following is String
String testString = "||A|||B||D|R|T|||TEST|||||"
I want to get "TEST" which is after 12 "|"
How can I manupulate String to give me characters after 12 "|"
I will appreciate any help.

Loop over the string, looking at each char with charAt(itn index).
Compare each char to '|'.
If it matches, increment the counter.
If the counter is 12, then take the substring from your current position in the string to the end.

Disabled button generates events

Hello,
I have a radio button that I want to disable while a background process is running.
After the process finishes, I enable the button again.
However, if the user clicks on the disabled button during the background process, an ActionEvent still gets generated.
Then when the button is re-enabled, it responds to the event that was generated while it was disabled. I want to prevent my button from responding to events generated while it was disabled.
I do not want to use the getGlassPane.setVisible(true) technique because I still want my cancel button to be able to generate events during the background process.
I am using JDK 1.3.1 and my button is in a panel contained in a JFrame application.
Suggestions?
Thank you,

Slideshow not resuming after certain buttons are used?

Hello,
I have this slideshow that I'm so close to having completed, but there's one issue I'm having with it not resuming after certain buttons are used. I've tried to figure out what could be causing this but I just can't see what it could be. I feel I'm so very close to having this completed if it weren't for this one issue.
In the slideshow buttons '1' and '2' work perfectly, however buttons '3' to '6' are not working completely as they should. During the slideshow, as it plays through the slides if you click on button '1' or '2' you are taken to the corresponding slide and then the slideshow automatically resumes, which is correct. However, if you click on any of buttons '3' to '6' you are still taken to the corresponding slide, but the slideshow does not resume and stays on that particular slide. I've looked over the Action Script 3 code several times and I just don't see what could be causing this but I'm not too experienced so there could be some error, no matter how minor, that I am missing.
I've attached the file and if anyone has any advice at all or can help in any way I would REALLY appreciate it!
Thank you,
William

In looking at the post I just made just now, I notice my attachment didn't come through. I'm not sure why this happened, but here is the code I'm using for the buttons:
btn1.addEventListener(MouseEvent.CLICK, btn1ClickHandler);

    gotoAndStop(10);
play();
btn2.addEventListener(MouseEvent.CLICK, btn2ClickHandler);
function btn2ClickHandler(event:MouseEvent):void

    gotoAndStop(210);
play();
btn6.addEventListener(MouseEvent.CLICK, btn6ClickHandler);
function btn6ClickHandler(event:MouseEvent):void
    gotoAndStop(259);
play();
And here is the code I'm using for slide images:

IDM Generate-Event in Sentinel

I have an IDM environment setup and I configured the Audit PA to send
events to the Sentinel IDM Collector. Sentinel is setup with the IDM
collector via audit to receive the messages. The setup works fine for
all built-in events.
What I am now trying to do is get custom events created with the
Generate-event token in IDM in Sentinel. They show up as an undefined
event and reference the LSC file. I have located the LSC files, but am
not able to modify those files directly. I have tried modifying them in
the cache, in the zip file after importing, and in the zip file before
posting. I tried modifying them in the zip file, then updating the xml
file with the hash values, but still am not having any luck with this.
The next thing I stumbled upon was the 'Custom Execution Mode'. I have
added the custom.js file and a LSC file which is referenced, but am not
sure of exactly what to add in the custom.js file to make the events get
properly recognized by Sentinel. Currently, my custom.js file has the
following for the customInit section:
Collector.prototype.customInit = function() {
// load additional maps, parameters, etc
var file = new File(instance.CONFIG.collDir + "dirxml_GCA.lsc");
this.MAPS.LSCMap.extend(this.CONFIG.collDir + "dirxml_GCA.lsc",
"#EventID");
return true;
I have uploaded the file dirxml_GCA.lsc and verified that it exists in
the plugins_repository for the aux_Identity-Manager... zip file.

Hi robertivey,
This is a great question; as you've seen we've included some general
methods to customize and extend existing Collectors, but to do so you
also need to know a little bit about how the particular Collector you
are extending works. We have plans to add a bit of specific
documentation to the IDM Collector since it's so common to generate
custom IDM events.
What you need to know is that normal nAudit events contain a number of
pre-defined fields such as Date, EventID, Originator, Target, Text1,
Text2, and so forth. These pre-defined buckets define a datatype and a
little teeny bit of semantics to the values contained within them, but
then on top of that the protocol uses the LSC file to add an additional
layer of semantics on top of the basic elements by adding an additional
descriptor to each field in the event per event ID. So for example
you'll see "Text2 Title" as something like "Client IP" which tells you
that the value in Text2 for event ID 00031550 is the client IP of the
system that connected to and logged in to the UserApp (note that LSC
files use an 8-digit hex value for the event IDs; I believe IDM's policy
code uses decimal so you'll have to convert).
In our IDM Collector, what we've done is written a little parser that
knows what to do for any given value in any given nAudit event field.
For this example, we've written a parser that knows to take the value in
Text2 and put it in Sentinel's "InitiatorIP" field, adjusting for
endianess and the like if necessary. If you look through the LSC file
and through 'dirxml.js', you'll see that for every combination of nAudit
field and semantic LSC definition, there's a defined parser. We use the
nAudit field codes defined at the top of the LSC, so you'll see a
function: "String.prototype["T-Client IP"]", as an example.
Now, to extend this structure is quite simple - you need to define the
equivalent of an LSC file for your custom events. To do this, copy some
lines from the existing LSC into a new file and edit them to match your
events:
1) Change the event ID to match your events. Always prefix with '0003'
- the last four digits are the hex version of your event code, so '1000'
becomes '03e8'.
2) Give your event a name
3) Assign semantic labels to your custom event fields; you should have
paid attention to the first layer of semantic meaning in Originator,
Target, etc, but fill in more detail as applicable.
Note that if you can, re-use the same semantic labels that you see
applied to other, similar IDM events.
OK, once that's done, you need to add your new LSC file to the
Collector using the "Add auxiliary file" process detailed on the
Customization page.
Next, you need to load your new LSC file and use it to extend the
existing one. Simple: from the SDK, grab a copy of custom.js and add
lines like you have above (you don't need to create a new File object
though, the single 'extend' line is sufficient).
Finally, edit your Collector and set its Execution Mode to 'custom',
then restart.
Your events should now be parsed!
The only caveat is that if you don't re-use semantic labels from other
IDM events, you'll need to define your own parser for your own
field/label combination, which you can do in custom.js just by copying
one of the parsers in dirxml.js and modifying the function name to
match.

?xdofx:if(($p_email is not null or $p_fax is not null ) and $p_ver is null and S_C = 'ABC' )?>
<?xdoxslt:set_variable($_XDOCTX,'SC','LIST_PRI')?> <?end if?>
So here i need to set the variable 'SC' with value 'LIST_PRI' once the above if condition satisfied. then i tried to get the value as below :
<?if: xdoxslt:get_variable($_XDOCTX, 'SC')='LIST_PRI'?><?L?><?end if?>
But it is not working properly with if statement and set_variable statement, please help me on this
Thanks

Change the code as follows and give it a try.
<?if:(($p_email is !='' or $p_fax !='') and $p_ver= '' and S_C = 'ABC' )?>
<?xdoxslt:set_variable($_XDOCTX,'SC','LIST_PRI')?><?end if?>
Or send the RTF and xml file to bipuser@gmail and I will take a look. Update this thread to let me know if you have sent me the files.
Thanks,
Bipuser

How to stop a while loop after certain time using Elapsed time vi

how to stop a while loop after certain time using Elapsed time vi.

Hi Frankie,
Just place the Elapsed Time VI inside the WHILE loop, and wire the 'Time Has Elapsed' output to the conditional terminal in the lower right corner (which should be set to 'stop if true' by default).
In the future, please post your LabVIEW questions to the LabVIEW Forum. You have a much better chance of getting your questions answered sooner, and those answers can then help others who are searching the LabVIEW forums. Thanks!

How to manually generate events in SMC 3.5 ?

Dear,
We are using the SDK of SMC 3.5 to build an application. To test the application, how can we generate events manually ? I'd like to have a script on Solaris that, when run, generates an event in the SMC database. Does anyone have such a script ?
Best regards,
Marc.

Convert the CR2 files to DNG files, a folder at a time, using the latest DNG Converter that is from Adobe: http://www.adobe.com/downloads/updates/
OR buy an upgrade to LR 4.x.
