Main vi with control for each vi

Hello,
I have a set of VIs that I am trying to be able to call from a main vi. The main vi front panel is just a set of boolean controls. The block diagram for the main vi is a single while loop that contains all the controls which are each wired to a case structure that calls each vi when set to true. There is a different VI being called for each control and case structure. The loop has a condition of continue while true which is wired to constant true which is outside the loop of course. I have also tried the same with a timed loop, but either way it is very basic indeed.
Now when I run it, I can press one control and it will then start up the vi front panel that I selected. That's fine, but then after that, when I press another control on the main VI, nothing happens. Another thing I noticed is that if I turn ON all the controls and then run it, they will all work, meaning all VI front panels selected will appear.
The issue is that when one or more controls are set to true and the respective VIs are called, it seems that the loop that controls all the VIs is no longer running. I would like to be able to select one VI, and then continue to select another VI and so forth.
Any help would be greatly appreciated.
Thank you

I would still consider dynamic launching of the subvi instead of making many loops, one for each subvi. The issue you will find (although the many loops is conceptually easier) will be in scalability, What happens if you want to launch 20 loops, are you going to drop 20 loops on your Block diagram, also what happens if you want to take advantage of the event structure (you really want to do this if you plan on a GUI of any complexity) you can put the event structure in each loop which will cause you to have to poll each loop and then you will need to do tempo control in each loop. From a readability stand point a single loop with an event case that launches the subvi is veary easy to follow as well. This is just my opinion though.

Adding a check box control for each row of data in a DataModel

Hi all,
I need to add a checkbox control for each row of data on a DataModel object.
I have a "commandButton" at the bottom of DataModel, and whenever someone checks some of the rows on that list of rows,
I need to get the selected dataModel(fragment of the list) in my backing bean.
How do I achieve this functionality in JSF?
Thanks,
Meghasyam.

Thanks,
Meghasyam.You'll want to have a wrapper class as suggested above, which has a "selected" boolean in it. Then use the "binding" attribute of the h:selectBooleanCheckbox component to bind the checkbox to that property... Make the property public and specify the properties exact name in the binding... bindings do not append "get" to the EL.
Here is an example of what your table might look like... This code would display the list of names with a checkbox to the left of each name... When the check box is selected, the "selected" property of that wrapper class is set to true or false as needed. Then when the form is submitted, and you are inside your actionListener or action method call, you can look through your collection of wrapper classes asking each one if it was selected or not... Then do whatever you want with them... In this example, replace "myBackingBean" with the name of your backing bean, and "names" with the name of the method in your backing bean which returns the collection of wrapper classes... create a flag "public boolean selected" or similar in your wrapper class..
<h:dataTable id="namestable"
value="#{myBackingBean.names}"
var="aName">
<h:column>
<h:selectBooleanCheckbox binding="#{aName.selected}"/>
<h:outputText value="#{aName.nameText}"/>
</h:column>
</h:dataTable>
Let me know if that isn't clear enough and I'll see if I can find a better way to explain it...

I have albums in my iMAC with description for each photo that I can show up on slide show so that I know the place that is in the photo. If I synchronize my photos to iPOD, I am unable to get the Descriptions also copied. How do I ensure this?

I have two questions:
1) I have multiple logins in my iMAC. How do I move photos/albums from one login to another?
2) I have created albums with "Description" for each photos, so that, in a slide show, any one can see what is being shown on the photo. When I sync albums to my iPOD, the "Descriptions" are not getting copied. How do I ensure that the "Descriptions" also get copied so that it can be a real back-up?
Thanks

Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your iPhoto thumbnails - this may take several tries
Also what version of iPhoto? What recently changed?

Are there any apps for having seperate volume controls for each app if multiple apps are playing at the same time?

Are there any apps for having seperate volume controls for each app if multiple apps are playing at the same time?

I don't think you can do that the volume is universal, but maybe turn down the volumes in the app settings?

How to append parameter with URL for each record in table control?

Hi,
I have one table control which contains 5 columns.
(tripno, startdate, destination, reason, activities)
In 5th column, i need to display URL for each record.
for ex:
www.abc.com/test?tripno=1
www.abc.com/test?tripno=2
www.abc.com/test?tripno=3
when user clicks a particular hyperlink, it navigates to another page/component thru URL with one key field(tripno) to retrieve related records in next page.
1) i am not able to assign tripno to each record. when i assign tripno, its taking the last value which i assigned. ie. tripno=3 only.
How to assign URL to Reference field of LINK_TO_URL element at run time?
OR
2) we can do like this.
Simply assign url to reach record without key field.
www.abc.com/test
www.abc.com/test
www.abc.com/test
when user clicks a particular link, we can assign corresponding key field to the URL.
Where should i write this event? Bcoz, LINK_TO_URL doesnot have event.
how to do?

Hi MOg.
Not sure whether I understand you .. but in the 5th column you want to have the reference URL. Is this the activities columen from you example?
Nevertheless, you need a attribute (String) in your context node which contains the URL. Bind this to the reference filed of linktourl. If you can not extend the structure you can create a sub node (cardinality 1:1) which contains the refernce attribute.
Then loop over all elements and concatenate www.abc.com/test?tripno= with the tripno of the current element into the reference field.
Hope tis helps,
Sascha.

SQL Agent Permssions With SSIS for each loop not looping through files

Hi I am Having trouble getting a ssis package to iterate through a file directory using a proxy account set up in Sql Server.
So I have a package that loops over csv files. If I run the package manually or set the sql agent job to run as Sysadmin the pakage runs fine all files are processed.
However if I use the proxy account. the package completes but no files are processed. there are no failures, there is no error handling set up in the control flow. the for each loop container simply does not recognise any files when run under a proxy.
Note: the proxy is set up with credentials to access the folder. the credential is also set up with the server admin server role... still nothing
i'm not sure is this is a ssis or permissions problem?
Any comments will be appreciated

Can you check this and see if you've configured all the steps correctly
http://www.mssqltips.com/sqlservertip/2163/running-a-ssis-package-from-sql-server-agent-using-a-proxy-account/
Also enable logging in package and see if you're getting any error messages obtained in output table/file based on the logging option you chose.

Controling For Each

Hy people! i have one doubt! i have a xml that have 10 purchase orders. i use this command to get duplicated purchase orders <?for-each@section:xdoxslt:foreach_number($_XDOCTX,1,var,1)?> . In layout i have 20 purchase orders. the first 10 are the original and the last 10 are duplicated! my doubt are: i want to put the "original" in the first 10 purchase orders and "duplicate" in the last 10 purchase orders . i try this with position() command but i cant control the foreach. when i have only one purchase orders it works fine . the problem is when my xml have more rhan 1.
someone have any suggestion? any help would be appreciated.

Hi Stuart
I read again your question.
Do you mean that the longer your program is running, the more time it takes to stop the execution once you hit a "stop button" that effects your while continuation ?
If you really have such a central "button" it might be a problem with memory. D you have a way to monitor the memory usage, like with the Windows task manager ?
If you have a problem with memory, check what is going into your loops. Labview has sometimes not very obvious ways to create local variables or references, that are not automatically destroyed.
Again a sample vi would help. It's just that I have only LV 6.0.

Open dialog box window with checkboxes for each child record - Please Help

Hello Everybody
I have a 10g form with master record and 20 child records. In the child record form, currently there is a “Notes” Editor, which pops up when user click the “Edit” button. In the “Notes” editor, user enters remarks if anything is missing. For example, typical remarks will be: Statement is missing, LOC paper is missing etc.
Now, I would like to replace “Notes” editor with a dialog box. In the dialog box , I would like to add checkboxes with values “Statement is missing” and “LOC paper is missing” etc. along with “Notes” field. The user can select checkboxes. The value of the checkboxes should go in the “Notes” field with the ability to edit it. This way, user doesn’t need to type the most common notes every time.
I have created a “NewNotes” dialog box with checkboxes and multiline text Item. It is pops up when I click on the button. I have also created to WHEN_CHECKBOC_CHANGED trigger for each checkboxes so that the its value will go in a multiline text item.
But, I am not sure how I can link “NewNotes” dialog box to the each record in child record block. I would really appreciate it if anybody could give me some idea.
Thanks,

if i understand correctly you have a note item (based on table) on every child record? when you open the dialog box: how do you put data from notes to dialog box? in the same way as you can write it back ...

Tree with checkbox for each level

1. I have a tree an I want to add a check box to every node. I saw this fonctionality with Java and with a lot of programs (install with choises). I don't know if this is possible with FORMS. If not how knows a solution for this problem ?
2. My tree is based to a SELECT and I want to add a parent for my tree
and I don't know how to do it. The problem is this : the value for each node from the first level IS NULL.
Thanks
Bye

I need this functionality because I have to select data's from a tree with 3 or 4 levels (like in the install software when we select to install only what we need).
There is a lot of information and it's difficult to display all of it in the screen.

Video Playlist with description for each video

Hi all,
I'm trying to create a page for one of my clients where I will store a bunch of videos. I came up with something like this.
http://www.relationsmith.com/gunnery/media/gunnery-media.html
You click on each button and you watch different videos. Pretty simple! Now my challenge is this:
I would like to display different descriptions for each video whenever the viewer clicks on one of the buttons with the video names. If anybody could give me any clues about this I'd really appreciate it.

Issue with XSLT For each loop in B2B Mapping

Hi All,
I am trying to map the inbound 997 Payload into Headers and Lines Table. I am using the For Each XSLT Construct to map the Loop AK2 of 997 into the 997 Lines Collection.
Issue I am facing is that if the Loop AK2 is repeated for 33 times then for all the 33 times only its first element's value is getting passed into the target of mapping file.
in coming payload
<Loop-AK2>
<Segment-AK2>
<Element-143>810</Element-143>
<Element-329>0001</Element-329>
</Segment-AK2>
<Segment-AK5>
<Element-717>A</Element-717>
</Segment-AK5>
</Loop-AK2>
<Loop-AK2>
<Segment-AK2>
<Element-143>810</Element-143>
<Element-329>0002</Element-329>
</Segment-AK2>
<Segment-AK5>
<Element-717>A</Element-717>
</Segment-AK5>
</Loop-AK2>
<Loop-AK2>
<Segment-AK2>
<Element-143>810</Element-143>
<Element-329>0003</Element-329>
</Segment-AK2>
<Segment-AK5>After transformation using XSLT file the payload looks like as follows
<ns0:XxmfiEdi997_AckLines>
<ns0:lineId>33</ns0:lineId>
<ns0:trxSetIdentCode>810</ns0:trxSetIdentCode>

<ns0:segmentCode/>
<ns0:segmentPosition/>the Element-329 of incoming source payload is mapped to trxSetControlNumber of target payload, the issue is obvious from the above XML data that trxSetControlNumber is always having the value 0001 for every occurence where as its expected to fetch the value of the element of its corresponding occurence not the first elements value.

Hi,
In your xslt code within the for loop, for the trxSetIdentCode why are you using the xpath "/ns1:Transaction-997/ns1:Loop-AK2/ns1:Segment-AK2/ns1:Element-143"? It should be just "ns1:Segment-AK2/ns1:Element-143". Similar changes for segmentError and trxSetAckCode also should be done. Remove the '/ns1:Transaction-997/ns1:Loop-AK2/' part from your xpath expressions inside the for loop and try it.

Create id, update id with date for each record

Hi,
Please give me brief idea or document for this concept:
I need create id, create date, update id, update date for each record inserted or updated in database (in few tables).
1) how user id can be obtained?
2) Is it better if i use views instead of tables for this?
3) is it possible for each record?
Please show me complete scenario. a piece of code can also be helpful.
thanx in advance.

Where do i go to match up the BPM for each track i lay to match up?
How do i get the Volume line to pop up on each track so i can fade accordingly?
Thank you to those who can help out

Do I have to set up unique apple id's with emails for each iPod

My kids each got iPod touchs for Xmas. I got them set up but with my apple id. When they text the others messages
Show up on the others iPod. They are only 6 and 9 and don't need email yet. Can I create them unique id's and link them to my email?

But if I leave the id set up as the same one but with different emails won't it all still go through the same apple id and therefore still show up with the same information on both ipods?
When I send a txt to my phone from ipod 1 it shows as their dads id, then if I go into the ipod 2 txt msg it shows the conversation.
