Control Factories And JPD Data Palette

Hello all,
I have added a task control to my JPD as a factory (because the JPD needs to create multiple instances of this task), and the api for the control (not the factory) shows up on the data palette. I'm assuming workshop is intending this as a shortcut through the factory methods, however when I drag one of the data palette methods or callbacks onto the JPD - Workshop does not realize the control is a factory, and produces error messages because it tries to call the control's methods directly (without first instantiating one with the factory).
What's up? I have noticed this in both sp2 and 3.
thanks,
Markus

I found it.
When I drag the "Navigation Buttons" component, four new action controls are created in my binding context. These operate the corresponding action on the BC4J RowIterator.
Now, what interest me to know, is how to affect the range control (JUCtrlRangeBinding) to implement a page selector in my web page in which I dragged a Table (or Dynamic Table) component.
I already reproduced all the widgets from the ancient (9.0.4) Datascrollercomponent.jsp but I don't know what URLs and events to generate to affect my BC4J components through the ADF DataControl.
I anyone got hints about this, they will be welcomed.
Thank you.

How to control required and optional data elements

I am developing a web service using a stateless EJB. By default, when I use servicegen, the WSDL contains nillable="true" for all elements. How can I modify my EJB code so I can specify which elements are required vs optional?
Thanks.

Hi,
Use Function Module READ_TEXT to retrive the long text.

Best way to control and read data from multiple instruments?

Hello,
I'm building an application to test power supplies involving multiple pieces of equipment over a couple of different comm busses. The application will also send control instructions to some of the instruments, and read data from some of the instruments. The reading and control profiles will not run on the same schedule (variable length control steps, configurable read interval).
I was thinking of using a queued statemachine (producer/consumer) for the control profile and another to read the data, but I got concerned that there would be collisions between sending control commands and read commands to the same machine. Is there a suggested design pattern for implementing something like this?
Timing of the commands isn't critical down to the milisecond, but I need to collect reasonably accurate timestamps when the data is read. The same is true for the control commands.
Here are the instruments I'm going to use, if the are control, read, or both, and the communication method
Instrument Funtions Comm Method
Power Supply Read data Communicates to PMBus Adapter
PMBus to USB Adapter Read data USB (Non-Visa)
Switch control relays USB (VISA)
Power Dist. Unit read data/control outlets SNMP (Ethernet)
Electronic Load read data/control load GPIB (VISA)
Thermal Chamber read data/control temp Ethernet (VISA)
Thanks,

Hello, there is a template in LV called "Continuous measurement and Logging".
It can give you some idea how to properly decouple the "GUI Event handler" top loop (where your Event structure is) from the DAQ and other loops.
You do not need to totally replicate the above example, but you can find there nice tricks which can help you at certain points.
The second loop from the top is the "UI message loop". It handles the commands coming from the top loop, and regarding to the local state machine and other possible conditions and states, it can command the other loops below.
During normal run, the different instrument loops just do the data reading, but if you send a control command from the top loop to a certain instrument loop (use a separate Queue for every instrument loops), that loop will Dequeue the control command, execute it, and goes back to data reading mode (in data reading mode the loop Dequeu itself with a "data read" command automatically). In this way the control and data read modes happen in serial not in parallel which you want to avoid (but I think some instrument drivers can even handle parallel access, it will not happen in really parallel...).
In every instrument loop when you read a value, attach a TimeStamp to it, and send this timestamp/value couple to the DataLogging loop via a Queue. You can use a cluster including 3 items: Source(instrument)/timestamp/value. All the instrument loops can use the same "Data logging" Queue. In the Datalogging while loop, after Dequeue-ing, you can Unbundle the cluster and save the timestamp and data-value into the required channel (different channel for every instrument) of a TDMS file.
(Important: NEVER use 2 Event structures in the same top level "main" VI!)

Control design and simulation palette

Hi all
I've recently installed LV 8.2 professional edition on my PC.
Watching the function palette i've seen the sub-palette 'Control design and simulation' empty... Is it normal? Do i need some toolkit to see something in it?

If LabVIEW is installed in "c:\program files", it means that you installed LabVIEW 64bit. You should install LabVIEW 32bit, which will go to "c:\program files(x86)" and will be compatible with your toolkit.
There is nothing wrong with the installer. You simply picked the wrong product.
Do NOT copy files between the two mentioned folders. One is for 32bit applications and one is for 64bit applications (assuming you have a 64bit OS).
The toolkit is not compatible with 64bit LabVIEW (Details).

Control Plane and Data Plane

Hi there,
I'm trying to figure out how to determine and how to differentiate between control plane and data plane especially in troubleshooting MPLS VPN. Any keyword that distinguish between them? It seems to be confusing for a newbie here :)
Thanks in advance.
maher

Hi Maher,
The control plane is simply the set of processes that are responsible for disseminating information on routes, labels etc within a network. This includes routing protocols whose job is to communicate information on routes between different routers. The information provided by these protocols is then used to building routing/forwarding tables.
The data plane is simply an abstraction used to describe the actual flow of data packets using paths determined by the control plane. The control plane traffic carries control traffic (which is not end-user data) whereas the data plane traffic is actual end-user data.
There is no single command that you can use to distinguish between the two. The commands you have on a router that can be used to view control plane operation are as such:
sh ip route
sh ip cef
sh ip bgp ...
sh ip ospf ...
sh mpls forwarding-table...
etc... and many, many more
Typically, there isn't a clear demarcation between commands that display control plane info and those that display data plane information... You could use commands such as the following to get some idea of data traffic flowing through a router:
sh interfaces
sh policy-map interface
etc.
Hope that helps - pls rate the post if it does.

I was trying to get my personal computer contacts and calendar in outlook on my iphone and ipad. I was told to use icloud. I went to control panel and then icloud and selected my contacts and calendar. Now ALL MY DATA IS DELETED FROM OUTLOOK. Help!!

I was trying to get my personal computer contacts and calendar in outlook on my iphone and ipad. I was told to use icloud. I went to control panel and then icloud and selected my contacts and calendar. Now ALL MY DATA IS DELETED FROM OUTLOOK. Help!!

I was just on the line with Apple Tech support. First of all, I learned that when you link contacts to iCloud, it moves all your contacts to another/new address book...look for aother address books and you will see it. But I found the new address book dies weird things and changes the "Display Names" format. Evidently (per Apple support tech) there is no way to avoid this problem...so I just delinked the iCloud from my contacts. The contacts stayed in the iCloud address book...so I exported them to a CSV (comma separated value) file and saved it on my desktop and then imported that list into my original contacts folder. Now everything is back the way it was...being able to use my contact address book the way I did before. I was surprised that they never considered or realized this problem...but then the tech guy admitted that they really don't have A LOT of experience using Windows PC's.

Datalogging and Supervisory Control : how to share data among LabVIEW applications on the same network?

I'm new to DSC. Is there an example program or article about how to share data (live data and data saved after running a program) among LabVIEW (using DSC) that is very basic? I would like to share live data and test reult data (eg. excel) among computers on the same network (may be LAN). Does sharing data over a network by using DSC makes whole system (all computers) down when one computer is locked up?

Hi,
The easiest way to network DSC data is using "network tags". The way you do it is by simply configuring the server PC as you normally would do for a local application.
Then from a remote compute, which we can call a client computer you can go to Tag Configuration Editor and option "File >> Import Network Tags.."
In the window that opens up you can hit the browse buttom and navigate to your server computer, select the .scf file you want to have and hit the buttom import.
Save the "client .scf" file locally and now you have in the client the same configuration you have in the server and your data is networked, from there on is just a matter of manipulating the data.
I hope it helps

I need to scan an input string for EOF (control Z) and then view the data that has come in since the last EOF.

I'm talking to a Furness micromanometer. It sends a string of three lines formatted as follows:
Time                 xx:xx:xx xM
Velocity            xxxxx ft/m
Temperature    xxx.x degC
I want to watch the input, and when I see the EOF character (ctlZ), I want to display the three lines of text sent since the last EOF. Any help is appreciated.

Lynn, attached is the original vi I wrote months ago. It works, but occasionally there seems to be a disconnect between the instrument and LabVIEW. The string received is shown in the upper left corner of the front panel (Micromanometer output) is the string last received. Then it's parsed out into teh three columns. AS you can see from the block diagram, I made a rather complex vi, although that was NOT my intent. Occasionally, as I said, things don't work right. Instaed of the first line beginning with "Velocity", it might read "city" and then everything is sort of offset, and the data is corrupt. After closing and reatarting LabView it usually works correctly. SO, I decided to go with a simpler, less complex approach. Instead of sending the T to the instrument to trigger it, I simply set the Furness to sample at one second intervals (locally - on its front panel interface)and send its data out on the serial port. Then I want Labview to monitor the port, and read the data whenever it sees there is date to read. I don't know if I can use EOF or the start bit, or what. I just wrote an application like this for another instrument, but I was able to determine the number of bytes in the string (19). I just used a property node (Bytes at port), compared the numer to 19, and if it was greater than or equal to 19, I read the port. It works great, but I can't seem to get a handle on what I'm doing wrong here. Anyway, attached is the old vi, as well as the beginning of the new one. Help??!!!

Iphone 5s and "forced data useage"

Hi all,
I was an android guy for years but finally went for an iphone 5s this time around and signed up with Verizon for the new $45 plan. Unltd Text, talk, and 250MB of data or AKA "The Wifi Only Plan." I came from metro PCS and enjoyed the same deal, but now I get with a better carrier with better coverage. I am fine with a low data amount plan because I have wifi at home and work. But this iphone 5s is forcing me to use data and I believe that it is not fair and want a rep to chime in on this situation. Some of the points may be able to be fixed on my end - so let me know how, but i think most are in a catch 22.
1) Most importantly... Voicemail. I go to the voicemail icon on my phone and if my cellur data is disabled... then I can not reach it. This forces me to turn on my data just to fetch voicemail which is a basic service and should be inclusive into my unlimited voice portion of the plan. Is there a way in the iphone 5s to get around this?
2) iMessage. This is sent across the data line of the carrier. I have had a few problems sending and receiving messages iphone to iphone because I have supposedly turned the data feature to iMessage off. Not good, not reliable service.
3) System Services. Eventhough it is only KBs of data it is still my data pool and should not have to pay for the auto system services that run on the phone. If I can control this on Iphone, lemme know where, but it seems that if I turn my data on for my phone these will auto send and receive data to where as individual apps I can block.
Also is there a data warning text I can receive when I get close to my monthly alotment?

I'm not a rep, but ....
1. Dial *86 instead of using the built in Visual Voice Mail.
2. Don't use iMessage. Unassociate your device with iMessage. Turn it off and just use SMS.
3. You can't change that. And as you noted, it doesn't use much data.
Yes. Log in to your My Verizon account you can set data alerts.

Here's how to do ALV (OO) with dynamic fcat, int table and editable data

Hi everybody
Here's a more useful approach to ALV grid with OO using dynamic table, data NOT from DDIC, dynamic FCAT and how to get changed lines from the grid when ENTER key is pressed.
It's really not too dificult but I think this is more useful than the ever present SFLIGHT methods from the demos.
This also defines a subclass of cl_gui_alv_grid so you can access the protected attributes / methods of that class.
You don't need to add the class via SE24 -- done fron this ABAP.
When you run it click Edit for the first time.
After editing data press ENTER and the break point should bring you into the relevant method.
Code developed on NW2004S trial version but also works on rel 6.40 on a "Real" system.
The code should work without any changes on any system >=6.40.
All you need to do is to create a blank screen 100 via SE51 with a custom container on it called CCONTAINER1.
The rest of the code can just be uploaded into your system using the SE38 upload facility.
When running the program click on the EDIT button to enable the edit functionality of the grid.
Change your data and when you press ENTER you should get the break-point where you can see the original table and changed rows.
This program is actually quite general as it covers Dynamic tables, building a dynamic fcat where your table fields are NOT in the DDIC, intercepting the ENTER key via using an event, and accessing the protected attributes of the cl_gui_alv_grid by defining a subclass of this class in the abap.
I've seen various questions relating to all these functions but none in my view ever answers the questions in a simple manner. I hope this simple program will answer all these and show how using OO ALV is actually quite easy and people shouldn't be scared of using OO.
Have fun and award points if useful.
Cheers
Jimbo.

Hi there
IE7 doesn't give me the add new page option and I get 404 error when trying to access the "How to contribute" section.
I'll load up Firefox later (this browser usually works when IE7 doesn't always work properly).
I'll copy the stuff to the wiki when I've got the browser sorted out.
Cheers
