How to maintainCorrelation using JMS control

Hi I am sending and receiving message from differnt
Queue in WLI.Using JMS Control how we maintain
correlation. Even though it is a asyncroneous
communication I want the reply back for further
process in JPD. I try it out it shouws the below
error message.
<5/07/2007 12:11:00 PM EST> <Error> <WLW> <000000>
<errMsg=onMessage(): Could no

ue?URI=/TestWSAccess/proce
sses/process.jpd(1183516524671):a:AmadausMsgChannel:li
stener].
I receive the response upto the Queue. I couldn;t get
it back to my jpd.

May be following info may help you establishing Co-relation
Two-way messaging requires that every received messages be correlated with the instance of the application that sent the original outgoing message. This correlation is typically managed for you by the JMS control, so no action is necessary on your part. To learn more about message correlation, see the explanation of the send-correlation-property and receive-correlation-property attributes for the @jc:jms annotation.
To enable two-way messaging with queues:
1.
On the JMS control, specify the name of the JMS queue to which you want to send messages by setting the value of the send-jndi-name attribute on the @jc:jms annotation.
Specify the name of the JMS queue from which you want to receive messages by setting the value of the receive-jndi-name attribute on the @jc:jms annotation.
To send a message from your web service, call the JMS control's default method (sendTextMessage, sendBytesMessage, sendObjectMessage or sendJMSMessage depending on the message type selected when the control was created), or a custom method you have defined for the JMS control.
4.
To be notified when messages are received on the receive queue, implement a callback handler for the JMS control?s callback (receiveTextMessage, receiveBytesMessage, receiveObjectMessage or receiveJMSMessage depending on the message type selected when the control was created), or a custom callback you have defined for the JMS control.
The following is an example enabling two-way messaging:
public class MyService {
* @common:control
private MyQueueControl myQueue;
* @common:operation
public void sendID(String personID) throws Exception
myQueue.sendTextMessage( personID );
myQueue_receiveTextMessage(String message)
// message has arrived from queue, perform desired operations

How can we use TABLE CONTROL in BDC and WORK FLOW of ABAP.

how can we use TABLE CONTROL in BDC and WORK FLOW of ABAP.?
please explain the important questions.

How to deal with table control / step loop in BDC
Steploop and table contol is inevitable in certain transactions. When we run BDC for such transactions, we will face the situation: how many visible lines of steploop/tablecontrol are on the screen? Although we can always find certain method to deal with it, such as function code 'NP', 'POPO', considering some extreme situation: there is only one line visible one the screen, our BDC program should display an error message. (See transaction 'ME21', we you resize your screen to let only one row visible, you can not enter mutiple lines on this screen even you use 'NP')
Now with the help of Poonam on sapfans.com developement forum, I find a method with which we can determine the number of visible lines on Transaction Screen from our Calling BDC program. Maybe it is useless to you, but I think it will give your some idea.
Demo ABAP code has two purposes:
1. how to determine number of visible lines and how to calculte page number;
(the 'calpage' routine has been modify to meet general purpose usage)
2. using field symbol in BDC program, please pay special attention to the difference in Static ASSIGN and Dynamic ASSIGN.
Now I begin to describe the step to implement my method:
(I use transaction 'ME21', screen 121 for sample,
the method using is Call Transation Using..)
Step1: go to screen painter to display the screen 121, then we can count the fixed line on this screen, there is 7 lines above the steploop and 2 lines below the steploop, so there are total 9 fixed lines on this screen. This means except these 9 lines, all the other line is for step loop. Then have a look at steploop itselp, one entry of it will occupy two lines.
(Be careful, for table control, the head and the bottom scroll bar will possess another two fixed lines, and there is a maximum number for table line)
Now we have : FixedLine = 9
              LoopLine = 2(for table control, LoopLine is always equal to 1)
Step2: go to transaction itself(ME21) to see how it roll page, in ME21, the first line of new page is always occupied by the last line of last page, so it begin with index '02', but in some other case, fisrt line is empty and ready for input.
Now we have: FirstLine = 0
          or FirstLine = 1 ( in our case, FirstLine is 1 because the first line of new page is fulfilled)
Step3: write a subroutine calcalculating number of pages
(here, the name of actual parameter is the same as formal parameter)
global data:    FixedLine type i, " number of fixed line on a certain screen
                LoopLine type i, " the number of lines occupied by one steploop item
                FirstLine type i, " possbile value 0 or 1, 0 stand for the first line of new                                                               " scrolling screen is empty, otherwise is 1
                Dataline type i, " number of items you will use in BDC, using DESCRIBE to get
                pageno    type i, " you need to scroll screen how many times.
                line      type i, " number of lines appears on the screen.
                index(2) type N, " the screen index for certain item
                begin     type i, " from parameter of loop
                end       type i. " to parameter of loop
*in code sample, the DataTable-linindex stands for the table index number of this line

How can one use Mission Control with two monitors? Please bring Spaces back

How can one use Mission Control with two monitors. With Spaces I could treat each space as a single desktop.
SyBB

I use two monitors at work and have no issue. I have my mail set to use Desktop 1 and iTunes set to the second monitor of Desktop 1. I have browsers set to Desktop 2 and Fusion and RDC set to Desktop 3.
Two things that may help you. In System Preferences > Mission Control, disable the setting "Automatically rearrange spaces...". This screwed with assigning applications to certain spaces. And the other thing is don't use full screen on apps that support it. This just makes your second monitor superfluous.

How can i use activeX Control in labview?

how can i use activeX Control in labview?
please describe me step by step.
thanks.

Well..that was quite helpful..but now I'm encountering certain problems. I've attached the VI I've made.
I don't need sound at the moment so I dropped it. (Although I tried to play it..but all I could hear was a very annoying sound.) Secondly I don't want to display any date or time..so i dropped that property too.
Now when I run this Vi...the webcam turns on, the screen of videocapx pops up..then the webcam light goes off..and another pop up appears saying..labview is not responding..and i have to close it reluctantly.
I haven't placed the stop capture property in this vi. i checked it by placing it too..but that doesn't work.
I would like to notify that my actual task is to acquire image and then compare it with another one already present on my pc. I want you to please help me out..solve my first query then I'll proceed with the latter part.

How does labVIEW use ActiveX controls?

How does labVIEW use activeX controls?
I recently wrote an activeX control in VB and noticed that it would not work if the control was set so that its properties could not be set in ambient mode. This may suggest that labVIEW uses some activeX controls only in ambient mode.
Is this the case or are there more complexities?

Dan,
Which version of LabVIEW do you have?
As per the KnowledgeBase bellow, in versions of LabVIEW prior to 5.1 you would get errors accessing the ambient properties.
ActiveX Controls in LabVIEW 5.0.1 Containers Cannot Access Ambient Property
Do your controls use the Ambient.UserMode to determine when the control is being used in a development environment? When embedding ActiveX controls into a container on the front panel, by default, the ActiveX control generates and responds to events, i.e. it is running, even when LabVIEW is in edit mode.
Right-click an ActiveX container and select Advanced»Design Mode from the shortcut menu to display the container
in design mode while you edit the VI. In design mode, events are not generated and event procedures do not run. The default mode is run mode, where you interact with the object as a user would.
Information can be found in the LabVIEW help files

Can I use, and how can I use voice control with my iPad 2?

Is it possible to use the voice control with my iPad 2? If so, how can I use it? Since there is no siri for iPad yet, I'd like to use something similar to it and I've seen this built in voice control before but I was not sure if it's possible with the iPad.

Not yet, however you can download the new google app. This offers voice seeking on the net.

How can I use table control to enter data

Hi all,
I want to use table control to enter data, instead of using textboxes.
So that the user can enter many data at once and just click the save button at the end of the work, only one click.
How can I use the table control at this context?
Thanks.

2. put it in archive mode,
3. shutdown and made a cold backup
4. Created backup control file (alter database backup control file to trace)
5. I started up and created some archived log files.
Second Computer
1. I copied all files created in the step 3 above except the control file
2. I create all the same map directory on the 2nd computer as in the 1st computer
3. I recreate the control file from the script got in the step 4 above
4. I Copy archived log files generated at the step 5 in the local directory in the second computer
5. I set the logsource and set the autorecovery to on
6. I recover the database: RECOVER DATABASE USING BACKUP CONTROL FILE UNTIL CANCEL
Error got:
the archived log file applied do not go beyond the first one?,How could I do to applied all archived log files copied from the first computer to the second computer to have the same data?

How i can use labview control or indicator in VB or C++

Hi,
I would like to use labview control or indicator in thierd party application like VB or C++ or .net. Please help me, how i can use this?
Thanks

You can't. A LabVIEW control is a LabVIEW internal object that has no direct link to any OS object entity on any platform it runs on. As such other applications would have no means to access that control object or interact with it in any meaningful way.
Instead you should probably look into ComponentWorks from National Instruments. That is a collection of ActiveX (and .Net?) controls similar to the ones you find in LabVIEW, and those can be embedded into Visual Basic or any other development environment that allows embedding ActiveX controls.

2 iPhones, 2 iCloud Accounts but 1 Windows 7 PC. How do I use iCloud Control Panel so that changes made change both accounts?

Help!
We have two iPhones, each with an iCloud account as my wife and I have different contacts (some are the same though), text and e-mail requirements. However, my Win 7 PC will only allow one instance of iCloud Contol Panel to run at any one time, and so when a change is made to Outlook 2010, only one iCloud account is updated. I have got around this with the Calendars by sharing the information, so when I change my calendar it is reflected on her iPhone and iPad. But when I make a change to contacts, they are updated in Outlook, but not on her iPhone or iPad until I exit the iCloud Control Panel with my details and enter hers. It is way too easy then to end up with duplicates and alsort of chaos.
So what is the work around? Does anyone else have this problem?
Thanks in advance.

Hi Lars,
In the examples folder there are some examples for simple operator interfaces. In the programmer help file they is a section on creating a teststand engine and the steps involved. Uses these notes and say the LV simple operator interface you can match up the steps and how to achieve them. In the Resource Library under TestStand there are plenty of useful notes, code, presentations to help you on your
What you are trying to achieve is to start the teststand enine running from Labview. Open a sequence file. Once you have that sequence file loaded you can then start to manipulate the properties on that sequence, such as your local boolean.
Hope this gives some pointers

How do I use my control key to highlight multiple options in a PDF?

How do you select multiple options from a selection field in a PDF form? I've tried control and mouse click as the directions indicate on the form. However, I am a new Mac user and I do not know if the control commands are the same. I viewed the commands and combonation key commands in the list provided on this support site. I could not find one to address this specific function.

Hi Rick,
Well, following up on the previous posting, I actually did figure out how to make it work but it seems rather inefficient. I can insert a new paragraph right after the paragraph that has the table anchor but when i cut the table, i also cut the paragraph i just created. So to get around that, I create two paragraphs, so that there will be one paragraph left after i do the cut and that is the paragraph that I paste the table into. Once the table is pasted into the new paragraph, I delete the other paragraph that I created.
Here's the updated code from the for loop:
var vTbl = vDoc.GetUniqueObject(Constants.FO_Tbl, vTextItems[i].obj.Unique);
var vAnchorPgf=vDoc.NewSeriesPgf (vTbl.TextLoc.obj)
var vAnchorPgf2=vDoc.NewSeriesPgf (vAnchorPgf);
var vAnchorTextLoc=new TextLoc (vAnchorPgf2, 0);
var vTblTextRange=new TextRange ();
vTblTextRange.beg.obj=vTbl.TextLoc.obj;
vTblTextRange.beg.offset = vTbl.TextLoc.offset;
vTblTextRange.end.obj=vTbl.TextLoc.obj;
vTblTextRange.end.offset = Constants.FV_OBJ_END_OFFSET
vDoc.TextSelection=vTblTextRange;
vDoc.Cut (0);
vTblTextRange.beg.obj=vAnchorTextLoc.obj;
vTblTextRange.beg.offset = 0;
vTblTextRange.end.obj=vAnchorTextLoc.obj;
vTblTextRange.end.offset =0;
vDoc.TextSelection=vTblTextRange;
vDoc.Paste (0);
vAnchorPgf2.Delete();

of 'SORT'. You will need to copy this to the PAI of every
screen and change the name of the module, and the actual
itab for this screen
MODULE SORT_screen100 INPUT.
   CASE SAVE_OK_CODE.
      WHEN 'SORT'.

Scrolling the table control
Now let's look at scrolling.
(assume that the name of your table control is T1)
In the screen logic you will have:
                Loop with control T1.
                   module get_Looplines.
                Endloop.
                    Module get_looplines.
                      Looplines = sy-loopc.
                    Endmodule.
In the PBO of the screen you will have a module that loads
the itab and determines the total number of lines read.
                  Module load_itab.
                        .      (select database table and
append to itab)
                   describe table itab lines linecount.
                 Endmodule.
We now have all the values necessary to construct a scroll
module.
MODULE SCROLL INPUT.
CASE SAVE_OK_CODE.
WHEN 'P--'.
   T1-TOP_LINE = 1.
WHEN 'P-'.
   T1-TOP_LINE = T1-TOP_LINE - LOOPLINES.
     IF T1-TOP_LINE < 1.
        T1-TOP_LINE = 1.
     ENDIF.
WHEN 'P+'.
   T1-TOP_LINE = T1-TOP_LINE + LOOPLINES.
     IF T1-TOP_LINE > LINECOUNT.
        T1-TOP_LINE = LINECOUNT - LOOPLINES + 1.
     ENDIF.
WHEN 'P++'.
   T1-TOP_LINE = LINECOUNT - LOOPLINES + 1.
ENDCASE.
ENDMODULE.                 " SCROLL INPUT
Or else you can use the below code
    WHEN 'P--'.
      CLEAR SY-UCOMM.
      CTR1-TOP_LINE = 1.
    WHEN 'P-'.
      CLEAR SY-UCOMM.
      CTR1-TOP_LINE = CTR1-TOP_LINE - LINECOUNT1.
      IF CTR1-TOP_LINE < 1.
        CTR1-TOP_LINE = 1.
      ENDIF.
    WHEN 'P+'.
      DESCRIBE TABLE ITAB1 LINES N1.
      CTR1-TOP_LINE = CTR1-TOP_LINE + LINECOUNT1.
      IF CTR1-TOP_LINE > N1.
        CTR1-TOP_LINE = N1.
      ENDIF.
      CLEAR SY-UCOMM.
    WHEN 'P++'.
      DESCRIBE TABLE ITAB1 LINES N1.
      CLEAR SY-UCOMM.
      CTR1-TOP_LINE = N1.
Other hints for using the table contro
1. Setting the number of lines.
2. Scrolling to a spcefic line.
1. Setting the number of lines.
tc1-lines = 500.

How can I use the Control Design & Simulation module in the Mobile (PDA) modul?

Hi everyone!
I have to create Bode and Nyquist plot from Transfer function on a PDA, but I can't use CD&S Modul when I'm opening a new Mobile project.
Thank you for your answer!
Sincerely yours,
Jenő Kocsis

Does it have to any transfer function? Or is it some limitations
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
