[Urgent] LabVIEW locked?! Help!!!!

Hello everyone,
I am currently working on a project related to nanomotion stage control using PCI-7344 and LabVIEW 6.1. I met a problem in using the Labview and it is extremely urgent (I have to make it work in 24hrs). I've never used LabVIEW 6.1 before, and it is really weird. The problem now is: I am not able to wire blocks and delete blocks in the block diagram. Though now I can right-click and then drag blocks from the function panel into the diagram, the blocks have no terminals, and there's no way for me to select the block I just draged in, and I cannot wire the blocks or delete them as well. If anybody knows how to solve this problem, please let me know!!!! I really appreciate it!!!
Thank you for your help!!!
Regards,
Xiaofei

Hi Xiaofei,
I have noticed similar behavior only when you copy and paste code from a higher version of LabVIEW to a lower version. If this is not what you are doing, did you try simply restarting LabVIEW? If none of this works, you should reinstall/repair your LabVIEW installation.

Labview locks at startup with the network cable attached

I have an embedded application that is running winXP and Labview 7 Express. I have my VI running from the startup menu as I have no keyboard, mouse or monitor normally attached. the application uses TPC to commincate over a wireless network. When I boot the computer with the network hooked up Labview locks up and a few minutes later the computer shuts down. If I close Labview from Task Manager and restart the app it works fine. The TPC part of the application is not running until a toggle switch is activated so the TCP part of the program is not active at start up.
Any help would be appreciated.

Is it possible that Labview is trying to run the application before windows has fully come up?

Urgent JMS Problem,Help!!

I meet a urgent problem about JMS,I use wls61 sp1
but when serverl MDB subscribed to one topic,problem
accur and not all of the subscriber seems to receive the
message,I know that sp2 have slove the bugs.but I just
want to get the patch of jms for wls61sp1.
This is very urgent,can anyone help me to
get the patch?
Thanks a lot

This sounds like the symptoms that I am currently suffering,
under Weblogic 6.1 SP2.
My situation is that I have processes on several "satellite"
Weblogic servers that all subscribe to the same set of several
JMS Topics published by a "central" Weblogic server. The servers
are all using Weblogic 6.1 SP2 (non-clustered). It appears that
only one of the subscribing "satellite" servers receives the
messages published. After a couple of experiments, it appears
that the first "satellite" server to register with the Topics is
the one that receives the messages, even if that "satellite"
server is restarted, until such time as the "central" server is restarted.
It appears from Eric's message that there is a patch for this.
How do I go about getting a copy of the patch? Or is my problem
different?
Thanks,
-Chris-

Hi. Does using the cover lock help battery life?

Hi. Does using the cover lock help battery life?

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Our students have entered passcodes when downloading ios 7 update and now ipads are locked, help!

Our students have entered passcodes when downloading ios 7 update and now ipads are locked, help!

If the iPad is running iOS 7 and the kid set up Find My IPad, then you can't restore it without the kid's Apple ID and password. The Activation Lock is a feature that people whined and whined to get, and is causing exactly the sort of problems many of us predicted when people were clamoring for it. If you can't get the kid's Apple ID, you'll have to call Apple Support and ask if they have any sort of workaround. My guess is that they'll have to replace the iPad, but they may have a solution they don't talk about publicly.
This won't help for iPads currently locked for which you can't get the Apple ID, but if before you give out iPads to your students you go into the Restrictions and disallow changes to the accounts, they can't then turn in Find My iPad. Or you can set up Find My iPad yourselves to your own accounts and then lock the Restrictions so they can't set iCloud up to an account to which you don't have the Apple ID.

Labview lock-up issue, Dr. Watson Hard Error...?

We sometimes run our software vi a library with Diagrams. Sometimes this library can be as large as 50Meg. Our problem seems to occur when we accumulate files in the library over approx 370 or so. When we run the software, no memory leakage or usage issue seems to be present but the software will stop running and we'll get a Dr. Watsons error and the only way to recover is to turn off the PC and reboot. Is there a limitation to the size off a library with diagrams..? We found that if we remove some of the vi's internal to the library (say we reduce the number of vi's down to 325 or so) the lock-up issue goes away...?

Hello Dave M,
Thank you for contacting National Instruments.
Saving to and reading from large library files is very memory intensive. This is most likely leading to your error.
Please refer to the LabVIEW User Manual (Chapter 7, pp. 12-13) at the following link:
http://www.ni.com/pdf/manuals/320999e.pdf
The following Knowledge Base is also useful:
http://digital.ni.com/public.nsf/websearch/D5662AF762385C1A862566C2007FE40F?OpenDocument
The recommended limit of VIs in a library is 255. This number can vary depending on you memory capacity. It is also recommended that your libraries not exceed 1 MB in size.
To avoid this error, you might want to consider dividing your library into multiple libraries. Put your high-level VIs in one library and
group other VIs by function.
Alternatively, you can save your VIs in a Development Distribution directory by selecting File >> Save with Options... and selecting the Development Distribution option.
Let me know if you need any more help.

Urgent! Need help in deciding data structure to use

Hi all,
I need to implement a restaurant system by which a customer can make a reservation.
I was wondering whether vector would be able to be store such an object, The thing is I don't want a complex data structure. just sumthin simple cos i hardly have anytime left to my submission. sighz...
The thing is I need to able to search based on 2 properties of an object. Eg. I need to search for a reservation based on the customer name and the date he reserved a table.
But I am totally clueless how to search thru a vector based on 2 properties of the object... Would really appreciate some help. Like an example how to so so based on my program. Feelin so lost...This is all I have so far:

Urgent plz! Help resizing photos to specific size

Am another newbie with Windows XP with Elements v.4.0. Have been handed a project by husband to take some passport-type as well as portrait type photos of relatives from overseas & resize them to certain dimenions (ex: 2" x 2", or maybe even something in centimeters. (He keeps changing sizes on me!) The current photo size info showing up under photos in the Editor are varying between all 8 photos (ex: 5.12" x 3.413" (150 ppi)), etc. None of them have the same dimensions!
I have looked in the book & in HELP, but whatever I try to do, they look wierd & out of proportion (in EDITOR) after applying changes. I've also tried to just do it in the print dialog box, but the proportions are locked & if I change 1 (either width or height) the other 1 changes automatically & not to the size I want.
I just know that a program as advanced as this should have a way to do this with the photos not looking out of proportion when finished, but I can't seem to make it happen & would so appreciate any help given, as this is not the only time that I know I'll want to do this (I am heavy into scrapbooking-need I say more?!) Thanks so much in advance.

Hi Mark, I'm trying to use the crop tool, but the problem is, none of the images are allowed to be cropped. (They are scans of passport/government-type pages with photos & official description & stamps on them. I have to leave the images just as they were sent to us in email, except that I need to change the size of each of them to 2" x 2" & have them turn out to look in proportion.
With your 2nd suggestion (in Crop tool set target dimensions, as well as set resolution to 240 or 300 ppi), are there additional steps after that??
I followed the steps just as you had outlined & then went to try to print. It brought up a dialog box which still showed under the print size box the (original) actual size of the photo.
Here's what else was in the dialog box:
1) A warning saying: Image will print at less than 220 ppi at the selected size.
2) SCALED PRINT SIZE BOX:
Scale: 100%
Height: 2 inches
Width: 2.907 (there's a chain lock attached between the height & width).
If I change the width box to 2" then it changes the height box to 2.907.
What am I doing wrong? I just know this should be way easier than it is appearing to me right now. Thanks again. Glenda
P.S. I forgot to tell you that I have 2 printers to choose from (if it makes any difference). Besides the Epson, I also have an HP Deskjet 990cse Pro Series.

Urgent...Help Needed.1. Helper Class 2. Connection Pool

Hello,
1. There are few helper classes which has to be
shared b/w session and entity beans. But it
seems,state of the object is not transfered to entity
bean though the class has implemented Serializable
interface. I have archived all the helper class and
copied to j2ee\home\lib directory. The same jar file
is made accessible to server via updating <library-
path> in j2ee/home/config/application.xml file.
2. How can i utilise connection pooling in oc4j. In data-sources.xml, i am using
"OracleConnectionPoolDataSource" class. But i feel that connection pool is not utilised coz server hangs in the middle of the retrieval.
The value of max-connections is 50.
We are actually migrating from Weblogic 5.1.0 to Oracle 9i AS. In weblogic, we had given 10 max connections in weblogic.properties,it is working fine. But i dont understand why it is not working in 9i AS though the max-connections is 50.
Kindly let me know the solution at the earliest as it is very urgent to get the program running...
Thanx and Regards,
Achyuth

Hi,
hopefully I can help you.
1. There are few helper classes which has to be ...We have just the same constellation. We have put the HelperClasses in the
J2EE/home/lib dir, NOT specifying it in the application.xml. So everything works fine.
The only thing: never, again: never put these files within WEB-INF and the lib-dir.
With the HelperClasses in both we have only faced massive problems, mostly ClasCastExceptions.
We had once all the helperClasses within J2EE/home/applications/lib, but this requires to
specify this dir within the orion-application.xml within the appl dir in applications-deployment.
It also worked fine.
2. How can i utilise connection pooling in oc4j. In data-sources.xml, i am using ...I'm not sure of this, but I think, the container handles Connection Pooling, no matter what Factory you
specify. But I think, the Class hasn't to be OracleConnectionPool ... but I have to check this (right now

4. NewOrder.jsp - uses HTMLB taglib style. consists of a form and set its layout to GridLayout. It further calls another JSP file which consists of all other GUI objects, called "i1_NewOrder.jsp".
5. i1_NewOrder.jsp - creates instances of GUI Objects like InputField,etc and adds these instances to the GridLayoutCell.
Question:
i> I have to create a button called "Add NewLine" such that when the user clicks on it, an empty row should be automatically generated in the above table, which is created as in step 1.
Where should I add this button and where would the event be handled?
Please help. URGENT......
Awaiting Reply.
Thanks and Warm Regards,

Hi Ritu,
I had a very similar problem. The default TableViewModel does not support adding rows at runtime. You have to extend the TableViewModel for this - don't worry it is easier as it sounds.
Look here for the solution which was given to me by Detlev Beutner:
How to add a row in TableViewModel?
I hope this helps.
