Progress bar in LabView?

I realized a vi with a global variable integer that increments from 0 to
1000 and I want to realize a bar that progresses with that variable. is
there anybody who can tell me how make this thing in labview?
thanks a lot.

The problem is that the progress bar can visualizes the values between 0 and
1000 and I don't know why! Can u help me? I use the global variable in a
event structure and I don't know how do this!
Thanks

Défilement Progress Bar

Bonjourà tous,
J'ai un petit problème concernant le défilement des Progress Bar de LABVIEW.
En effet, comme vous pouvez le voir sur le VI joint, je comùmunique avec un compact RIO, et je voudrai que ma barre de défilement, s'active et progresse, tant que ma variable "Booleen" n'est pas à faux.
En d'autre mots, je veux que ma barre de défilement défile tant que je n'ai pas reçu la valeur que le compact RIO doit m'envoyer.
Pour le moment, j'ai fait comme il est indiqué sur le VI joint, mais lorsque j'arrive sur cette face avant, les transferts de données se font bien, la variable Booleen prend bien la bonne valeur au bon moment (Vrai à partir du début et devient faux lorsque j'ai reçu toutes les données), mais la barre de défilement ne défile pas
Pouvez vous me donner une astuce, ou carément une solution?
Merci

bonjour,
dans votre boucle où vous changer la valeur du progress bar, il faut cliquer sur le point rouge (devient une flèche verte) pour que la boucle fonction tant que la condition est vrai.

Progress Bar is not working in Labview 6i

Hi all,
i implemented one vi with Progress bar using labiview 6i. i created property node for the progress bar to set the range as 550 using scale >Range>maximum. progress bar is updating well until the value of 220. later the progress bar is starting from begining. What is the maximum range we can define for the Progress bar.? please see the attached picture . Am i missing anything from the figure?
thanks,

Hi kalpu,
as your "slide" is of datatype U8 it will not display values greater than 255…

Global Variable in Progress Bar

I have an existing labview code that is comprised of a main vi, which is the user GUI, and several (approx 70) sub vi's. I am trying to add a progress bar to the front screen (User GUI) that will immediately increment after it hits certain sections of code. I am doing this using a global variable to store the value of the current progress, and then attempting to write to the progress bar on the main screen after each incrementation. Is there a way to link the value of the main progress bar to the global variable so that it updates as soon as the value is incremented? The problem I am facing is that when I update the global variable in a subvi, the progress bar takes the value of the subvi after it is completed, skipping all the numbers in between. I realize this is because I am not correctly writing to the progress bar, but I am unsure how to do so. If this isn't a good method, does anyone have any suggestions?
For Example:
Main Vi SubVi1 SubVi2
(1-4) (5-8) (8-12)
Progress Bar: 1 2 3 4 8 12
(I did try the Progress Bar Library NI provides, but I need a progress bar on the Front Panel, not a pop up, so I can debug while the code runs)
Thanks- Adam

I'd go with a Action Engine to update the progress bar VIA vi server referance. Here's an example using a AE I have for just this type of progress bar.
If you haven't read Ben action engine nugget, it should be required, you can find it here
By constructing a "resource module" (a special AE that holds a referance to the resource to act on) after initializint the AE you can call any "method" on the resorce from any location in the application instance. These babys really let you do some interesting things to the GUI from wherever the real actions is taking place.

How to create a progress bar showing status on timeout of TCP Read function

Is there any way of creating a progress bar showing the status of a 'TCP Read timeout' time ... ?
I'm sending a data request to an intranet server via TCP Write, and then using TCP Read with a 2 min. timeout to receive the requested data. During this time i want to show the actual progress of the timeout in a progress bar.
Can this be done?
And do i have to implement some kind of multitasking to make it happen?
TIA

It can be done and you need to do some multitasking yes, but that is
quite easy in LabVIEW. A separate loop or subVI with loop will be
responsible for the progress bar. Set its scale to 0 and the number of
seconds of your timeout. In parallel to the TCP Read let this loop or VI
execute reading the time every few
seconds and calculating the
difference to its start time, passing this value to the progress bar
slider. Have an extra boolean global which aborts the loop and set this
boolean to FALSE before starting the loop/VI and TCP Read and setting it
to TRUE on return of the TCP Read.

Customizing OI to add step progress bar

Hello custom RTOI experts! I am attempting to make a customization to the full-featured LabVIEW RTOI (for TestStand 3.0) in order to provide the seemingly simple feature of a step completion progress bar on the execution page of the tab control. Let me explain a little behind the concept I'm going for. There are some steps in my sequences that take a relatively long time (15 minutes or so). During this period, a requirement of mine is to have a progress bar that gets updates every so often such that by the time the step would ordinary complete, the progress bar is at 100%. Initial attempts involved a separate VI that managed the progress bars, but having yet another window is not the ideal UI design... Instead, I was hoping to integrate this functionality into the RTOI so that each time a new step begins executing, additional custom data (the expected step duration) is (optionally) sent to the RTOI providing the progress update portion of the RTOI code the necessary data.
Is there any sample code out there that performs some similar task so that I can get a better feel for how the pieces fit together? In particular, there are a few things that are befuddling me:
1) What is a good way to store this custom information (step duration) in the sequence file? Should I modify the basic step types to add a new duration field which can be optionally set to something greater than the default, 0?
2) How should the step duration get passed to the RTOI? My current thought is to override the PreStep engine callback to send the custom duration field in a custom UIMessage, but that may be partly because I'm not familiar enough with the structure of the data is that is that is accessible via the sequence context...
3) How do I link the progress bar data to the actual execution page that is currently being viewed. Up to 4 executions can be running using the parallel model or the batch model in my sequences, so something would clearly need to be done so that when execution 1 is visible, the associated progress bar is shown, etc... I'm assuming I can trap on some event when the user clicks on an execution in the list bar, but there is no similar code in the out-of-box RTOI - all that appears to be managed automatically by linking the controls to the execution manager.
Thanks for any pointers or code samples (or even suggested reading) that anyone can give.

Thanks for the response.
I may indeed want to use the ProgressPercent message, but I'm not so sure just yet. I did not want to leave the responsibility of sending UIMessages up to the VIs and other code modules called by the sequence - I was hoping for a simple solution to provide a new field (ExpectedDuration) that can be set for any given step. In this way, the RTOI can manage updating the progress simply by counting seconds. Perhaps there is some timer callback that can be leveraged to perform this function?
What I have so far is as follows: I have a new step type called PassFailTestWithDuration. It is a copy of the PassFailTest step type with the addition of a ExpectedDuration property and a new PreStep which calls the PostUIMessageEx with a custom event (10001). The expected duration and the RunState.TestSockets.MyIndex both get passed as parameters. Inside the RTOI, I have added a UserMessage callback VI which stores the data in the appropriate slot of a global (indexed by socket index). (The global array is implemented as what I've heard called an action engine - there are init, read, and write actions that it can perform on data stored in the VI, and it is set as non-reentrant so that race conditions cannot occur). Each entry in the global array has 2 fields - the expected duration, and the current elapsed time. My idea was to continually update the current elapsed time for all active executions and simply show a progress bar for the "active" execution by displaying its elapsed time/expected duration in each necessary event...
I think my main question now is - how do you determine the RunState.TestSocket.MyIndex of the active execution in the execution manager (or application manager)? It seems like such an obvious thing to want to know, but I don't see it anywhere.
Thanks again for any hints you can provide!

How to increase the system progress bar height?

Hi
I just want to increase the height of windows system progress bar and it is not able to customize. It is having the option to adjust the width and not the height. For example the height of system progress bar used in labview installer is large compared to control which is in labview control palette.
I want the progress bar as in the below figure

Hi Mike
Thanks for your reply
I know that I can change height progress bar which is in modern palette. But if i customize it doesn't look like the system progress bar.
So what I have to do to make the progress bar similar to system progress bar which is in the image that I send you. If you have the customized control please send it to me.
Thanks & Regards

How to associate audio file with progress bar

Hi all,
I have a case in which I need to associate an audio file witha progress bar. What I want to do is to able to play a audio file which will say " Process started.." Process going on" and process ends, and it shoud be synchronized with the progress bar. Is there a way to do this .
Please let me know
Thanks,

Are you referring to a LabVIEW horizontal/vertical progress bar, which basically has a U8 integer constantly written to it? Is this in a loop as it fills up?
If so, there is an entire palette that allows you to play waveforms. As you're writing to your progress bar the number, you can keep checking what that number is (event or case structure), and when it hits particular values, you play particular sounds. Here is a screenshot of that palette.

Parallelized for loop progress bar

I have a for that takes a long time to execute and enabled parallelism to speed things up. I also want a progress bar. Before enabling parallelism, I simple had an indicator wired to the iteration counter and the array size that is being processed. This gave a good percent complete indicator. With the for loop parallelized, the indicator bounces around depending on which instance of the for loop happens to update the indicator. Is there a way to have an indicator inside a parallelized for loop?

A better idea is probably a simple action engine that increments with each call, incrementing an integer in a feedback node, and returns the total count. Since it is not reentrant, it will be shared by all loop instances.
Here's a very quick draft. See if it works for you. (Warning, only use it in one FOR loop overall).
Probably needs a few tweaks....

System horizontal progress bar cannot be customized

I noticed that I cannot customize a system horizontal progress bar by going to right-click>>Advanced>>Customize. When the control editor shows up, the customize mode button is grayed out.
I can customize a numeric control or a string control using the above procedure, so why can't I do the same for a system progress bar?

Yes. It makes sense that the system controls are not customizable.
However, I do have situations where I would like to customize the system controls. For instance, with the slide control/indicator, when you make the digital display visible, it shows up in a box. When your slide is a control, the right side of the box contains the increment/decrement buttons. When your slide is an indicator, these buttons are invisible, but the the box is still big enough to include them. So, the box on the slide indicator is unnecessarily big on the right side. Take a look at the example.vi and you will see what I mean.

FTP transfer progress bar

I'm trying to write an FTP application by using FTP library provided with LabVIEW Internet Toolkit library. I have a large file (>1GB) that I want to transfer from PXI Real-time controller to my host computer running Windows XP. On my windows machine I would like to show the users the progress bar and percent of the file being transferred just like the FTP windows provided by MAX from NI. Please See the attached screen capture. How do I accomplished that?
Thanks!

The low level file transfer is performed in vi.lib\addons\internet\utils\tcputil.llb\TCP Write Stream.vi
There is a shift register that contains the bytes left unwritten that could be used to determine the progress.
Issues:
You would need to modify this VI to expose the bytes left unwritten to your UI. In general, its not a good idea to change NI supplied VIs.
This VI is reentrant. It may be possible to have more than one FTP transfer happening at the same time; so using a LabVIEW global to expose the value would not be a good idea.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

Help needed please, with Iphone stuck with apple picture and progress bar after software update attempted

Help needed please, everytime I try to update the software version on my iphone it comes up with a message saying it could not be completed and is now frozen with the apple picture and progress bar on it. Do I unplug it and hope the macbook pro sees it again, I also stupidly did not back up before starting the download which I realise I will have to go back to the previous back up. This keeps happening, everytime I do this type of update, I'm starting to think I should just give up on updating my software on the Iphone. I thought it was happening because I was using a window based computer to do the updates, this time I used my Macbook Pro. Please somebody help

Problem installating Snow Leopard on old Macbook Pro with Intel Core 2 Duo. After creating partition on internal hard disk (Extended Journaled), installation starts but stops at half of the progress bar. Screen asking Restart appears.

Hello:
I have tried installing Snow Leopard via the installation disc on a Macbook Pro (2007) with an Intel Core 2 Duo, but I the installation has failed more than 5 times.
I have first formatted and partitioned the internal hard disk with Mac Os Extended Journal format.
Once the installation starts, it starts without a problem unti lthe progress bar gest until half completed then a screen asking for a Computer Restart shows up.
It asks to press the power button for some time until it the computer shuts down and then, press again to turn it on.
Once turned on, the installation disc gets readed, the installation screen appears again and asks again to start the whole installation process form the beginning.

Then you have a Hardware Problem.
Your system is Crashing part way through the install and Re-Booting because of the crash.
Could be the drive itself or it could be some other hardware part in your system. Like the RAM.
To check if it is the internal drive connect an External drive to the system by USB and do the install on that external. If the install completes then it more then likely the drive is bad. If it crashes again then it is more then likely some other piece of hardware in your system.

After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it.

The page load progress bar that was on the lower right of the window is no longer there. After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it. The tab has a circular progress wheel but this is useless for determining a stuck or slow loading page.
PLEASE NOTE: I am typing this in from a Windows based work computer but am asking about my Apple MacBook Pro that i use at home.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time. 
There is also a "Restore Previous Session" button on the default about:home Home page. 
Another possibility is to use:
* [http://kb.mozillazine.org/Menu_differences Firefox (Tools) > Options] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

When I try to empty trash, progress bar stops, and I have to reset finder

This has been happening for about a week or so. Regardless of what the files are, I am unable to delete them. Whether I do a standard empty trash, or a secure empty trash, I end up with the same progress bar that stops during the process. I've let it sit for several minutes and over an hour, leaving me the only option of doing a force restart of finder.
Currently I am unable to delete anything, putting a serious hold on my workflow.
It appears that many people are having all kinds of trash issues with Snow Leopard. I'm assuming Apple is working on a fix, but I'm not sure when that's coming out. Until then, if there is some kind of work-around, I'd love to know about it.
Any guesstimates on when Apple will release the next OS update?
Cheers.
