Break out of a while loop from outside the loop

Hello,
I have an application where I have some nested while loops. Is it possible to break the innermost loop from a control that is outside of the inner loop? My inner loop is running a scan and read operation on the serial port and is reading data as it somes in. I need this loop to break when the user presses a button located in one of the outer loops so that another section of the vi can execute. Thanks in advance.

Greg,
You should place the terminal of the button in the innermost loop and wire out from there to the other locations the value is needed. If these are nested loops, the controls will not get read until the outer loop iterates again and this can only happen if the inner loop has ended anyway. Thus your scheme will not work.
Alternatively, you can place the control in a loop that executes in parallel,then use local variables of it in the other locations, but the above solution is better.

How can I access the value of a loop index outside the loop?

I have a sequence structure in Labview 8.6. At one frame of the sequence I have a while loop. The loop runs for a while and then stops and the program then moves to the next frame of the sequence. Several frames further on down the sequence I have a cluster, the elements of which are outputs on the front panel. The index of the mentioned loop is one of the cluster elements, an numeric output. While the loop is running, I want the index to be displayed on the front panel in the output contained in the cluster. How can I do this?

The easiest way to do this is to use a local variable of your cluster. You'll need one copy set to read; connect that to a bundle by name, bundle in your index value from the loop, and wire the bundle output to a write copy of your local variable. You can create a local variable by right-clicking on the cluster terminal (in the block diagram) and choosing create local variable. You can change the local variable to read or write by right-clicking on it.
However, in general the use of both local variables and sequence structures is discouraged, and the right solution may be to rewrite your code with a while loop containing a case structure in which you update the cluster every time through the loop. This will look like a state machine; you'll also need a shift register in place of the loop iteration counter. If you post your code (ideally the VI, but if not then a screenshot of the block diagram) then we can provide more useful assistance.

I'm creating an array using a for loop, how do I get the values outside the loop while it is running? thanks

I'm creating a set of values using a for loop and a shift register inside the loop. I want access to these values outside the loop as they are being created inside. When I connect a wire from the shift register to a display outside, it doesn't work. How do I do this? Thank you.

I tried to create the local variable that was wired to numeric indicator inside the loop. If I try to connect this to the analog output outside the loop, the loop just starts blinking and nothing happens, am I doing something wrong? Thanks again.

How to get the elements out of a for loop simultaneously during the loop execution

Hi,
I am student. I would like to know how to get the counter values outside the For loop parallely while the loop runs rather that getting the finally value outside the For loop. Looking forward for answers.
Thanks,
Athira
Solved!
Go to Solution.

You could use a notifier (since it is a single value) or a reference (with a property node) to a control that gets the value elsewhere in another VI.
If it is within the same VI, you could use a property node (right click > create > property node > value) from the control within the same VI located outside the loop.
If you promiss NOT to abuse the use of Local Variables, you could use that to only write from ONE location within the For Loop to a control outside the loop, similar to the property node mentionned earlier. (Of course, I will be struct by lightening for mentionning that and scolded by other LabVIEW coders for having a change of heart on the use of Locals.... Shivers are already crawling up my spine).
You could use a queue, but that might be an overkill, unless: the count is generated faster than it is being read elsewhere...
As crossrulz mentionned, can you describe what you will be doing with the count? Because synchronizing data (fresh / stale / etc) is very important within LabVIEW as it executes based on dataflow rather than a sequential order.
Hope this helps.
EDIT:
You have not fully provided the answer. We figured that much of your code from your description, but what is reading the value of the count? Is it in a separate loop? If not, it may only deal with the first value, which is likely 0. The proper advice depends on how you process the received data (count).

I need to link to a screen within a movie from outside the movie

Hi,
That last question was answered so quickly, I'll ask this
next one right away:
I need to link to a screen within a movie from outside the
movie (so for example, from file1.cp, I need to open file 2, screen
4).
Am I able to do this in Captivate 1?
Thanks,
Kim

I've just gotten a chance to check out these responses. About
the Flash - no can do. Don't have it. And about breaking the file
apart, that would get messy because I have several files already.
OK. At least I know my options are limited to linking to page 1
from outside, so I'll have to be creative.
Thanks for the response.

Pages (or Numbers) Template Cannot Be Opened From Outside the Application

Ever since the upgrade to Mavericks, I cannot open a Pages (or Numbers) template without being asked.....
Do you want to add this custom template to the Template Chooser? Then my only options are Cancel or Add to Template Chooser.
If I cancel, it won't open anything.
But this template is already in my Template Chooser.
So the only way to open a template in Pages (or Numbers) is to open the application first, and then click "New", and choose the template.
I can't figure out a way to open the template from outside the application, which is very very handy, rather than having to open the application every time that I want to access a template.
How can I open a template simply by clicking on it?

Yes, the problem is that opening the template from outside of the application will not open the application, showing the document. I only get this....

Problems while accessing images outside the web document-root folder

Our application runs on Oracle application server on Linux. Facing problems while accessing images outside the web document-root folder. This works with changes in global-web-application.xml by including the <virtual-directory> tag. The same change does not work when done on Linux machine. It is unable to find the image.

This is one of the least satisfactory aspects of site management in Dreamweaver, and several developers, including myself, have been pressuring the Dreamweaver team for some years to improve this. Who knows? They might eventually take notice.
The only way to do this at the moment is to create two site definitions, one nested inside the other. Set up the site definition normally based on htdocs as your site root. Then create a new site definition based on site. Dreamweaver will nag you that it can cause problems, but it won't actually stop you from doing it. The only potential problem is with site synchronization.
The problem with using site as the only basis for your site definition is that Dreamweaver automatically puts things like the Connections, Scripts, and other folders in the site root. So, everything ends up at the wrong level of the site hierarchy. Quite frankly, the whole thing is a bit of a pain. Dynamic site development was added to Dreamweaver only in version 6 (Dreamweaver MX), and no one had really thought through the need to store files outside the site root.

Why are my images scrolling from outside the Page width?

Why are my images scrolling from outside the Page width? I am positive i has all the settings correct, to have an image parallax scroll from the edge of the page into the page and out again. But the images are flying in from the browser width - not the page width. This is not the effect I am after.
Any suggestions on how to fix this? Given the key position is only linked to the height, I can't for the life of me work out how to ensure the images start moving from a certain position onthe left and right of the page.
Thanks

I think the effect you are seeing is a result of how the lineHeight is set up. By default, the lineHeight will be calculated as 120% of the size of the largest thing on the line -- in your case, this is the inline graphic. This is designed to leave space between the line before and the line with the graphic. So it is taking the height of the graphic, multiplying by 120%, and making this the distance between the previous line and the line with the graphic. So the bigger the graphic, the bigger the space above the graphic. Normally this works well with text, but in this case you may want to get closer to "set solid". You can do this by setting the lineHeight to 100%. Or you may wish to leave a couple of percent for the descenders of the previous line. Or, another alternative that may work well for you if you really know exactly where you want the line set, you could measure the graphic, add on the number of extra pixels to leave for the descenders, and make the lineHeight a constant. So you could do something like this:
<img lineHeight="104%" height="411"/>
or this:
<img lineHeight="423" height="411"/>
Obviously you would still need to specify the source and any other parameters you want on the image.
Note that if you are trying to fit a 200 pixel high graphic into a 200 pixel high container, you will hit the same problem -- in order to fit the graphic, the container will have to be slightly bigger than the graphic in order to fit the descenders on the last line. This is true even if the last line contains only the graphic, and no descenders (or text) at all.
Hope this helps,

Can anyone get personal information from my computer from outside the home

Hello, Is it possible for someone to get information from my computer from outside the house
? thanks

Sadly your credit card info is easy to pickup from the following insecure methods:
1. Connecting to a passwordless WiFi, or one with just WEP or WPA version 1 encryption. Always use WPA2. Make sure your password is not in any dictionary of any language.
2. Delete all browser cookies for retailers that have had credit card transactions before using the computer in a WiFi hotspot that has no password requirements.
3. Connecting to a website without at least 128 bit RSA key encryption and entering your credit card number in such a website. Browsers have a method of determining your encryption either by clicking the lock icon, or hovering over the lock icon, or viewing the web browser security settings. When making online transactions, do not save your credit card number to any website, and secure the website you are making a transaction with, with a password that isn't found in any dictionary.
4. Look at your credit card receipts wherever you use your credit card. Both the customer copy and the retailer copy should have all but the last 4 digits Xed out. If they are all visible, inform the retailer there are more secure credit card machines that do, and you won't purchase anything with them by credit card until they use such machines.
5. Gas stations, it is better that your receipt is not printed at all, and if it is, don't forget to check with the attendent if they have a copy of the receipt and get it from them.
6. Credit card wireless scanners. Apparently people have managed to scan other people's back pockets and get the credit card number off them. If at all possible don't leave your credit card in your back pocket, and use your front pocket, or a purse that you always keep an eye on.
If your bill online or otherwise indicate charges you don't recognize, get your number changed immediately, and dispute the charges within 60 days. If you don't you may be liable for them. Otherwise you are usually only liable for the first $50.

How can I use an American credit card to pay for a membership from outside the US?

How can I use an American credit card to pay for a membership from outside the US? My payment page is set up for Japanese credit cards. I can't change to the US store, because the "Select a Store" page just jumps to the "Products" page.
Has anyone else had this problem? Any help would be much appreciated!

Hi Batt5721,
Welcome to Adobe Forums.
The address and the country on the Credit Card should match the billing address then only payment would be possible.
Thanks

How to get the number of community members from outside the community

Hi everyone.
I need to know if there is any way to get the number of community members from outside the community, I mean, not using the "What's happening" webpart. I want to build up a page with a Webpart that summarize my three most visited communities indicating
number of members, three last messages in the newsfeed, and number of posts in blog, wikis, document libraries, etc.
Do I need statistics to get this kind of information? Should I use Sharepoint Object model instead?
Here is an example of what I need:
- Community name
- Number of members
- Community activity (messages, docs uploaded to library, etc)
- Number of posts in calendar, blog, wiki that belongs to community
Thank you all!

Hi Thuan.
Thanks for your answer but it does not help me because these communities are Sharepoint Communities not external sites so I need to get that information using SP object model and BCS in this case is useless.
EDIT
I found the solution using the search objects but I was only able to get members, discussions and replies
using (ClientContext clientContext = new ClientContext("URL_OF_ENTERPRISE_SEARCH_CENTER"))
KeywordQuery keywordQuery = new KeywordQuery(clientContext);
keywordQuery.QueryText = "The_Name_of_the_Community WebTemplate:COMMUNITY";
SearchExecutor searchExecutor = new SearchExecutor(clientContext);
ClientResult<ResultTableCollection> results = searchExecutor.ExecuteQuery(keywordQuery);
clientContext.ExecuteQuery();
System.Collections.Generic.IDictionary<string, object> ret = null;
foreach (System.Collections.Generic.Dictionary<string, object> resultRow in results.Value[0].ResultRows)
Console.WriteLine("{0}: {1} ({2})", resultRow["CommunityMembersCount"], resultRow["CommunityTopicsCount"], resultRow["CommunitiyRepliesCount"]);
This is a Console Application.
I hope someone helps

Premiere Pro CC's sequence lost. Is there a way to "search" for it from outside the project?

I seem to have lost a sequence created in Premiere Pro CC. I can't find it anywhere inside the Project bin.
We have so many same-name, older projects (between Auto-Save, different drives and so on) that looking inside each of them would take forever.
But we do know the name of the sequence. I am wondering if there is a way to "search" for a sequence name from outside the project?
Thanks

there is a way to "search" for a sequence name outside of the project,
but it would be a pointless waste of time.
sequences are only saved within the project file itself!!
We have so many same-name, older projects (between Auto-Save, different drives and so on) that looking inside each of them would take forever.
better get at it then!
