Right way to do software trigger?

I have been doing a program for electronics dropping tester. I am using one drop table sensor and one sensor attached to circuit board. I am dividing all 250kS/s rate two these two sensors. Also when I am using high speed resistance measuring in test I am also dividing the sample rate for those. I am using PCI-6225 card where is not hardware trigger channel so I need to do it with software trigging.
The trigger starts when the drop table hits the ground and it's undergo the acceleration which is measured from drop table sensor.
The problem is that the program somehow goes to loop or something in measurement. It remains measuring and doesnt end the measuring. It doesnt do that all the time but sometimes. I have tried to find out that does it go some repeating loop but it doesnt. So is that my triggering done so bad way that this whole Labview language jams ?
If someone can watch my code and say how it should be done? I have attached some of my code in this post. In the code the measuring structure part is framed with red frame. I know that this my code is badly done because I havent used so many subVIs like it should be done. This is my first Labview code what I have been doing. The layout is also too big because few subVIs but it fits somehow to two monitors.
Thanks a lot for reading this!

If you need all those channels, the chain on itself is ok.... even though you can remove the flat sequence structure without any changes done to the functionality of the code.
I suggest you to collect all On/Off settings into a boolean array and then pass it to a subVI. In this subvi you can do something like this:
This will enable you to decrease block diagram size in a quite decent (read: scalable) way.
hope this helps,

Software trigger with PCI-5122

I am going to program a board with PCI-6552 and in meantime in specific times capture the samples of the anolog output of the board by PCI-5122.
Is there any way to use software trigger and the data pattern of PCI-6552 (e.g. define a software event) to trigger the PCI-5122. If it is possible, how the software event can be defined and connected to the "send software trigger" block?

Whe using a software trigger with the 5122, you generate the trigger whenver you call the "Send Software Trigger" function. you can program the software events that cause this funtion to be called in any way you want.
In the simplest case, you could place the "Send Software Trigger" function in a while loop and only execute it when the user presses a button.

HSDIO conditionally fetch hardware compare sample errors (script trigger to flag whether or not to wait for software trigger)

I am moderately new to Labview and definitely new to the HSDIO platform, so my apologies if this is either impossible or silly!
I am working on a system that consists of multiple PXI-6548 modules that are synchronized using T-CLK and I am using hardware compare. The issue I have is that I need to be able to capture ALL the failing sample error locations from the hardware compare fetch VI... By ALL I mean potentially many, many more fails than the 4094 sample error depth present on the modules.
My strategy has been to break up a large waveform into several subsets that are no larger than 4094 samples (to guarantee that I can't overflow the error FIFO) and then fetch the errors for each block. After the fetch is complete I send a software reference trigger that is subsequently exported to a scriptTrigger that tells the hardware it is OK to proceed (I do this because my fetch routine is in a while loop and Labview says that the "repeated capbility has not yet been defined" if I try to use a software script trigger in a loop).
This works fine, but it is also conceivable that I could have 0 errors in 4094 samples. In such a case what I would like to do is to skip the fetching of the hardware compare errors (since there aren't any) and immediately begin the generation of the next block of the waveform. That is, skip the time where I have to wait for a software trigger.
I tried to do this by exporting the sample error event to a PFI and looping that PFI back in to generate a script trigger. What I thought would happen was that the script trigger would get asserted (and stay asserted) if there was ever a sample error in a block, then I could clear the script trigger in my script. However, in debug I ended up exporting this script trigger back out again and saw that it was only lasting for a few hundred nanoseconds (in a case where there was only 1 injected sample error)... The sample error event shows up as a 1-sample wide pulse.
So, my question is this: is there a way to set a flag to indicate that at least one sample error occurred in a given block that will persist until I clear it in my script? What I want to do is below...
generate wfmA subset (0, 4094)
if scriptTrigger1
clear scriptTrigger1
wait until scriptTrigger0
end
clear scriptTrigger0
generate wfmA subset (4094, 4094)
I want scriptTrigger1 to be asserted only if there was a sample error in any block of 4094 and it needs to stay asserted until it is cleared in the script. scriptTrigger0 is the software trigger that will be sent only if a fetch is performed. Again, the goal being that if there were no sample errors in a block, the waiting for scriptTrigger0 will not occur.
I am probably going about it all wrong (obviously since it doesn't work), so any help would be much appreciated!

Please disregard most of my previous post... after some more debug work today I have been able to achieve the desired effect at slower frequencies. I did straighten out my script too:
generate wfmA
if scriptTrigger1
clear scriptTrigger0
wait until scriptTrigger0
end if
generate wfmA
scriptTrigger1 = sample error event flag
scriptTrigger0 = software trigger (finished fetching error backlog in SW)
However, I am still having a related issue.
I am exporting the Sample Error Event to a PFI line, looping that back in on another PFI line, and having the incoming version of the Sample Error Event generate a script trigger. My stimulus has a single injected sample error for debug. For additional debug I am exporting the script trigger to yet another PFI; I have the sample error event PFI and the script trigger PFI hooked up to a scope.
If I run the sample clock rate less than ~133MHz everything works... I can see the sample error event pulse high for one clock period and the script trigger stays around until it is consumed by my script's if statement.
Once I go faster than that I am seeing that the script trigger catches the sample error event occasionally. The faster I go, the less often it is caught. If I widen out the error to be 2 samples wide then it will work every time even at 200MHz.
I have tried PFI0-3 and the PXI lines as the output terminal for the sample error event and they all have the same result (this implies the load from the scope isn't the cause).
I don't know what else to try? I can't over sample my waveform because I need to run a true 200MHz. I don't see anything that would give me any other control over the sample error event in terms of its pulsewidth or how to export it directly to a script trigger instead of how I'm doing it.
Any other ideas?

How to create a custom panel in the right way (without having an empty panel in the file info) ?

Hi Everyone
My name is Daté.
I'm working in the fashion industry as a designer and Design consultant to help fashion brands improving the design workflow by using Adobe softwares and especially Illustrator.
I'm not a developper, but i'm very interested about the possibility to introduce xmp technology to provide more DAM workflows in the fashion industry.
Fashion designers produce a lot of graphical objects in illustrator or Photoshop. Unfortunately they are faced to a big challenge which is about how to manage, search, classify and get this files faster. Of course PDM system or PLM system are used in the Fashion industry to manage data, but for many companies, implemanting this kind of database is very complex.
When i look at what you can do with xmp, it seems to be an interesting way of managing design files, then i started to follow Adobe instruction to try to build a custom panel.
The main idea is to (Theory) :
create custom panels used by fashion designers to classify their design files.
Use Adobe Bridge to search files, create smart collection to make basic reports in pdf and slideshows
Find someone to make a script able to export metadata in xml files
Use indesign and the xml file to generate automatically catalogues or technical sheets based on xmp values
I have created a custom panel by using the generic panel provided by Adobe and i have modified the fields to feet with the terms used in the fashion industry and it works well.
But unfortunately, when i try to create my own custom panel from scratch with Flashbuilder (4.6) and the Adobe CSExtensionBuilder_2 (Trial version), it doesn't work!
Here is the process :
I have installed flashbuilder 4.6
I have download the XMP Fileinfo SDK 5.1 and placed the com.adobe.xmp.sdk.fileinfo_fb4_1.1.0.jar in C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.6\eclipse\plugins
In Flashbuilder, i have created a new project and select xmp Custom panel
The new project is created in flashbuilder with a field with A BASIC Description Field
To generate the panel, right click the project folder and select xmp / Publish Custom Panel
The panel is automatically generated in the following folder : C:\Users\AppData\Roaming\Adobe\XMP\custom file info panels\3.0\panels
Go to illustrator, Open the file Info
The panel appears empty
The others panel are also empty
The panel is created and automatically placed in the right folder, but when you open it in Illustrator by selecting the File Info option in the File Menu, this custom panel appears empty!!! (only the title of the tab is displayed). This panel also prevent the other panels to be displayed.
When you delete this custom panels from the folder C:\Users\AppData\Roaming\Adobe\XMP\custom file info panels\3.0\panels and go back to the File Info, the other panels display their content properly.
I also try to use the plugin XMP Namespace designer to create my own namespace. this plugin is also able to generate a custom panel, but this one also appears empty in AI or Photoshop.
I try to follow the process described in Adobe xmp documentation many times, but it didn't works.
It seems that many peaople have this issue, but i dodn't find a solution in the forum.
I try to create a trust file (cfg), but it didn't work.
It would be so kind if you can help me to understand why i can't create a custom panel normally and how to do it in the right way.
Thanks a lot for your help,
Best regards,
Daté

Hi Sunil,
After many trial, i realize the problem was not coming from the trust file, but from the way i have created the custom panel.
There is 2 different ways, the first described below is not working whereas the second is fine :
METHOD 1 :
I have downloaded the XMP-Fileinfo-SDK-CS6
In the XMP-Fileinfo-SDK-CS6 folder, i copied the com.adobe.xmp.sdk.fileinfo_fb4x_1.2.0.jar plugin from the Tools folder and i pasted it in the plugind folder of Flashbuilder 4.6
The plugin install an XMP project
In Flashbuilder 4.6 i have created a new project (File / New /Project /XMP/XMP Custom Panel)
A new xmp project is created in flashbuilder.
You can publish this project by right clicking the root folder and selecting XMP / Publish Custom Panel
The custom file info panel is automatically published in the right location which is on Mac : /Users/UserName/Library/Application Support/Adobe/XMP/Custom File Info Panels/3.0 or /Users/UserName/Library/Application Support/Adobe/XMP/Custom File Info Panels/4.0
Despite the publication of the custom file info panel and the creation of a trust file in the following location : "/Library/Application Support/Macromedia/FlashPlayerTrust", the panel is blank in Illustrator.
I try this way several times, with no good results.
METHOD 2 :
I have installed Adobe CSExtensionBuilder 2.1 in Flash Builder
In FlashBuilder i have created a new project (File / New /Project /Adobe Creative Suite Extension Builder/XMP Fileinfo Panel Project)
As the system display a warning about the version of the sdk to use to create correctly a custom file info, I changed the sdk to sdk3.5A
The warning message is : "XMP FileInfo Panel Projects must be built with Flex 3.3, 3.4 or 3.5 SDK. Building with Flex 4.6.0 SDK may result in runtime errors"
When i publish this File info panel project (right click the root folder and select Run as / Adobe illustrator), the panel is published correctly.
The last step is to create the trust file to display the fields in the panel and everything is working fine in Illustrator.
The second method seems to be the right way.
For sure something is missing in the first method, and i don't understand the difference between the XMP Custom Panel Project and the XMP Fileinfo Panel Project. Maybe you can explain it to me.
So what is the best solution ? the right sdk to use acording to the creative suite (the system asks to use 3.3 or 3.5 sdk for custom panels, so why ?)
I'm agree with Pedro, a step by step tutorial about this will help a lot of peaople, because it's not so easy to understand!!!
Sunil, as you belong to the staff team, can you tell me if there is :
A plugin or a software capable to extract the XMP from llustrator files to generate XML workflows in Indesign to create catalogues
A plugin to allow indesign to get custom XMP in live caption
A plugin to allow Bridge to get custom XMP in the Outputmode to make pdf or web galeries from a smart collection
How can you print the XMP data with the thumbnail of the file ?
Thanks a lot for your reply.

Is there a way to prevent Software updates to automatically upgrade my printer drivers?

Hi everybody!
Is it possible to prevent Mountain Lion to automatically upgrade my printer drivers?
I'm using an iMac with Mountain Lion at work, and for my printer to work, I need to keep an older version of xerox drivers (newer versions are not supporting some features we're using at a corporate level). Is there a way to tell software updates to stop asking me to update those drivers? I would love to use the "update all" feature without having to continuously reinstall old drivers...
Thank you so much for your help!
Sincerely
Neff

Thank you Barney-15E, I tried to right-click and hide this update and for the moment everything appears to work just fine. I'll let you know if the update request pops-up again at the next software update.

Saving software trigger in project

Hi John, if you look at the attached screenshots view1 shows the top part of the project when I open it. In view3 the software triggers are present. In view2 I display the start condition settings of the project. When I open the project I have to remove software trigger A and then add it back to have both trigger A and trigger B buttons appears at the top as in view3.

The "right" way to handle multiple devices, accounts and the cloud?

Perhaps a bit premature, but I figure it's never too early to start planning.
Here's our current setup - I currently have four iDevices in the faily (three iPhones and one iPod Touch. All are syncing to the same Mac Mini, albeit with different logins (and different iTunes store ids). All four of these are kept in sync via Home Sharing so we have access to the music/apps/etc acquired by the others.
Enter the iCloud - how does this fit in? What's the *right* way to do this?
I can see two options:
1)     Continue to utilize four iTunes store ids, sync them via Home Sharing and add four iClouds
     Advantages
          totally independent devices, users, etc.
     Disadvantages
          must pay for four "iTunes Match" services to access non-iTunes music on each of the four devices
          will iTunes-purchased music automaticaly sync to iCloud if it is shared via Home Sharing (or only by the original purchaser)?
2)     Use one iTunes Store id for all iDevices
     Advantages
          single point of acquisition and distribution for all devices
     Disadvantages
          need to find a way to merge IDs (is this even possible?)
Are there other advantages/disadvantages to these options? Are there other options? What's the easiest to set up and support? Any other thoughts?
Thanks in advance for your input.

Well it seems like the first thing you should do is consolidate your iTunes libraries so that you don't have 4 copies of everything, one for each user logged in to your Mac Mini. How you do that is consolidate all 4 iTunes folders to one folder located in the /Users/Shared/ folder and update each of your iTunes to point to that folder accordingly. That way you have one iTunes library, only one copy of your media, but accessible from multiple users.
One caveat is that if somebody is logged on and has iTunes open, you can't fast switch to another user and open iTunes. Apple made it so that only one user and one instance of iTunes can open a iTunes library at a time.
For your iTunes match situation, it does sound like you would be much better off sharing a single Apple ID with one iTunes Match. For consolidating, make sure you have everything everybody has shared via Home Sharing to the main account you'd like to move over to, and then simply go to each device Settings, Store, and the sign out of the original Apple ID and logon using the shared main Apple ID. I just looked at it and the automatic downloading is already live in iOS! You can specify if you want to do music, apps, and books separately in case you may want to automatically download music but not apps or books.

Problem with slideshow in iPhoto. Photos look like they are all the right way up but when in slideshow action some are sideways.

even though all photos look like they are the right way up, when the slideshow commences, some of them display sideways. I have tried re-rotating them - and still have same problem. Help please - need it for Saturday night !

What version of iPhoto are you using? Are you creating the slideshow directly from an album or are you using the slideshow mode?
As a test launch iPhoto with the Option key held down and create a new, test library. Import some photos and test to see if the same problem persists. Does it?

Right way of configuring higher MTU over a Port Channel

Hi guys,
I have a running critical Port-Channel between two locations.
Here's the config
SW1:
interface Port-channel2
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
end
interface GigabitEthernet1/45
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode active
end
interface GigabitEthernet1/46
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode active
end
SW2
interface GigabitEthernet1/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode passive
end
interface GigabitEthernet1/2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode passive
end
interface Port-channel2
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
end
Now I need to increase the MTU from default value to 9198. What the right way to do it and avoid any connectivity loss, PortChannel restart.
Does it matter what switch I start first?
Thanks!
L.E. both SW are WS-C4948

Hi,
Because you are using layer 2 interfaces - there is no fragmentation support at layer 2, and interfaces receiving frames which have an unsupported size will be dropped.
I think the best way for you to proceed is to lab this up; and verify what happens - it may be that you need to make changes on switches at either end of the channel within a very short time frame to prevent too large an outage.
When you are ready to maike your change - think the best way to do this is to use the interface range command, and apply the 'mtu' command to all the interfaces in this range. I don't think it matters which switch you apply this change to first, and I don't believe if you are hinting at the 802.3ad (controlled by system-priority) decision maker, that it makes any difference.

Right way of login form...

Hello
I am a really newbie in web programming. I want to write a web application with JSF. I wonder what is the rgiht way of creating the login form. I tried to write a page segment file for it but page segments do not have prerender method so it cannot be fully controlled...I want something like that:
login control will be two parts..
if login info is not found in session, than it will show the login form.
if the user is found in session, than it will show the menu for the user...
but i couldnt do that because prerender methos is not available in page segments..
what is the right way for doing that kind of thing?

Indeed implement a Filter.
Once an user logs in, put the User object in the HttpSession. Let the filter check on this User object. If this User object is null and you're not in the login page, then redirect to the login page.
Do a Google search on "LoginFilter implements Filter" or "UserFilter implements Filter" and you'll find lot of examples.
http://www.google.com/search?q=%22LoginFilter implements Filter%22
http://www.google.com/search?q=%22UserFilter implements Filter%22
Here is an advanced one which actually doesn't redirect if the User object doesn't exist, but this might give you some new insights: http://balusc.xs4all.nl/srv/dev-jep-usf.html

Right way to dispose frame/components/containers?

Hi,
My application creates a lot of frames with lots of containers and components (heavyweights as well as light weights) inside them. I have obeserved that none of the frames/containers/components get finalized unless I do a remove/removeAll() over the respective container. Currently I just make a call to frame.dispose() to dispose it off and assume that all components would be reclaimed by the garbage collector at some point of time. Is that the right way to dispose off the frames and mark all its child components for garbage collection? Or is an explicit call to removeAll() required to release the memory. I am aware that garbage collection doesn't happen immediately and may take a while before the GC collects objects. I have run the application continuously for couple of hours and created/disposed a lot of frames during that period. GC recollected none of them (none of the components either) except for those that were removed by an explicit call to remove or removeAll during the lifetime of the session. I even hit OOM errors but none of the components were recollected.
What could be the problem?
Some additional information:
I overridden removeNotify() and finalize() methods to see what's going on. For all components removeNotify() was called (even if I don't do explicit remove/removeAll and just dispose off the frame) but finalize never gets called. My methods:
     public void removeNotify()
          super.removeNotify();
          System.out.println("Remove notify called "+compId);
     protected void finalize() throws Throwable
          super.finalize();
          System.out.println("Finalized component "+compId);
     }Thanks in advance.

Sorry to bother guys. The problem was not with AWT but with one evil component that was displayed inside most of my Frame classes and was also registered as an Observer with an Observable class. The event at which the component was supposed to unregister itself with Observable never got fired and this one reference prevented garbage collection of entire gui brigade. Damn! Tiny monster.
Anyway the issue stands resolved. Thanks for your time.

Right way to validate form fields !!

Hi,
I am having a form with many fields including TextFields, Dropdowns, DateFields, Checkboxes, Radiobuttons etc.
I am validating the most fields by making them REQUIRED. But I didn't found way to make Checkbox field required. So I am doing it by script by making its MANADATORY property to true. I am validating fields at the Form's preSubmit event.
All I want to know that whether it is the right way to validation i.e.
Making field.mandatory = true; (for checkboxes or may be some other field too)
Check it at preSubmit event of the form;
I want to code it according to best practices. That's why this question bounces up in the mind.
Thanks.

Right way to configure Tomcat JDBC resource for MaxDB

Hi,
i need to configure one tomcat server with a pool of connections for a MaxDB instance with follow database parameters:
MAXUSERTASKS=150
SESSION_TIMEOUT=60
i do this configuration on tomcat:
<Resource name="jdbc/myApp"
                auth="Container"
                type="javax.sql.DataSource"
                username="DBUSER"
                password="secret"
                driverClassName="com.sap.dbtech.jdbc.DriverSapDB"
                url="jdbc:sapdb://dbserver/DBNAME"
                maxActive="150"
                maxIdle="75"
                validationQuery="SELECT NOW() FROM DBA.DUAL"/>
is this the right way? there is a way to check if the pool is working at database side? at java side i checked that the javax.sql.DataSource.loginTimeout is Unavailable, then what is the better way to avoid errors like:
2008-06-02 13:54:36 2165 WNG 11824 COMMUNIC Releasing T187 command timeout
i think that this problem occurs because the SESSION_TIMEOUT is 60, and the loginTimeout is Unavailable at javax.sql.DataSource then the DBCP of tomcat dont know when need to revalidate the session.
thanks for any help.
Clóvis

Hi Clovis,
to be honest, I'm no Tomcat expert at all. All I can do is read the documentation.
The error message you posted was about an timeout due to a too long idle session.
From the changes in your connection pool setup I cannot see any parameter that would influence this.
Instead - as already written - you may either want to change the session timeout in general, for the user or (by adding some connection parameters) for the sessions.
Concerning the question on wether it's better to have many connections or just a few - well this depends on what the java tasks do with the sessions.
The connection pool is used for saving resources on the database side and the time necessary to logon and create a session.
So whenever any of the java tasks needs a db connections it should "just get one" from the pool.
When you have "high load" (by the way what exactly does that mean? High CPU usage on the J2EE server? Huge transaction volume? Many parallel transactions?) this does not change.
Anyhow you have to be aware of the fact that the database can only process as many SQL requests in parallel as there are user kernel threads (UKTs) and each of the UKTs need to be able to run on a seperate CPU core. Therefore if it's necessary to have real parallel SQL activity many connections may not be the best idea.
On the other hand this requirement is seldom necessary - most often sessions can wait a bit until they get the reply from the database and synchronize on each other later on. At least that's how we do it with NetWeaver.
