Logo on TV front panel

Hi All,
I've noticed that the logo on my TV (#32C100U1) does not light up and on just about everything that I've seen (Toshiba advertisiing, various websites, etc.) it appears to be on. I'm not sure if it is suppose to illuminate when the TV is powered on. And before calling Technical Support I wanted to hear what others have experienced. Any and all opinions/suggestions would be appreciated.
Thanks in advance,

Interestingly, I just bought this same model of TV just about a week ago from Best Buy. Got a good deal on it too. But like your TV, the logo on my TV doesn't light up either. I think that there's a couple reason for this. One, a lit logo would interfere with seeing the picture on the TV as well as possible. And secondly, having a LED lit all of the time would waste some electricity. Bottom line: the logo NOT lightning up is normal.

Using Front Panel Audio with Fatality Professional

I have a query regarding connections on the Titanium Fatality PCIe.
I have an XFi XtremeMusic PCI card and am considering replacing it with the Titanium Fatality XFi card. A couple of reasons, I like the shrouded enclosure, I like the little XFi LED logo, I want to move away from PCI cards in my system.
But one of the main reasons is to allow me to connect my Intel HD Audio connector to the card so I can use the Headphone/Mic socket on my case. So if anyone has these cards can they confirm that they have an Intel HD Audio connector on them. If so does connecting the headphone to the case socket mute the speakers?
Cheers

Well, I don't personally have one, but I was under the impression that every X-Fi had one. I know my X-Fi Fatal1ty (original PCI version) included it, and my Recon3D definitely does.
Plus if you check their shop website for the Titanium Fatal1ty Professional than the specs page lists a 2x 5-pin connector for "Intel HD Audio Compatible Front Panel Header" so it most likely does.
I would assume it would mute the speakers only if your case is fully Azalia compliant. By that, I mean the standard (as dictated by Intel) involves the use of two normally-open switches - one each on the headphone and microphone jack - which are closed as a result of plugging something into them. Some cases have these jacks which means it can detect when you plug something in and respond accordingly, but others use cheaper (we're talking differences in cents - not exactly substantial savings, but when you do it thousands of times over it adds up) switchless jacks and simply report them as always plugged in.
Just remember to set up the X-Fi panels to mute the speakers when you plug headphones in, as well as switch the output to headphone mode. You can actually set those two options separately on X-Fis.

Front panel Printing with A4 Standerd

Easy printing the test reports with the Front panel as per the A4 Standard.
For making the A4 Standard printing needs the option to make Pane A4 Size.
Then we can make easily create the front panel reports easy manner, add Indicator (result ,title, logo, auto signatures etc) in the report and generate the print out.

Developing a GUI on a computer monitor is that much different from printing an A4 (or letter for those americans insisting to use this peculiar standard ), that I think there are not many use cases to force it to the size of a piece of paper.
Alternatively, one could define a printing area, optionally being visible on the front panel and being able to print just that area. So put all controls and indicators you want to be printed in that area, leaving space for GUI elements you don't want to be printed.
The more I think of this the more I like it.
So, on second thought, kudos but preferably for a printing area to be defined by the user.
Greetings from the Netherlands where printers loaded with A4 paper are as common as water runnning from the tap.
(and yes, we all do have taps here ).

Satellite A200-1N1: "Satellite" LED on the front panel is not shining

Hi folks!
I notice that my LED with "Satellite" word on the front panel doesn't shine.
Do you have any assumptions about causes?

Hi Maresha,
The front 'logo' LED is enabled or disabled using a BIOS option 'Display Front Logo' which can be set to ON or OFF as you require. Access your BIOS settings (F2 during boot up) and check that this setting is set to 'ON'.

B540 - front panel not responding

The touch button (vloume, brightness) at the bottom of the screen are not working. Is it spoilt or have I accidentally disable them ?

Hi Jason,
Welcome to Lenovo Community Forums
I’m sorry to hear that the front panel touch buttons are not working as expected in your B540 All-In-One computer, I suggest you to check if the issue persists in BIOS menu as well. To access BIOS menu press F1 Key at the time of startup before the Lenovo Logo appears on the screen, then check if the touch buttons are working. If the issue persists in BIOS menu then it is hardware related. I would Strongly Suggest Calling Technical Support for Assistance for further assistance.

List of subvis that have front panel setup as pop-ups so i can beautify them

Hello,
I am upgrading an old project which has several subvis that pop-up if clicked on something asking for more information or confirmation during the operation by the user.
I want to make them look better and manintain consistent front panels with company logos and apprerance, how can programatically find and list all the subvis that are going to be open as pop-up so i can beautify them,
i dont care about the other subvis in the background that dont open-up.
Thanks

Bill,
One concern with that approach is the possibility of missing a subVI which very rarely pops up. Since the OP appears to be trying to clean up old code, missing something which becomes obvious to the end user only after it was supposedly cleaned up could be embarassing.

I was just thinking about places I worked where everything was organized into user libraries and that included dialog boxes. However, even if that was the case, I hadn't considered that there may be subVIs - like maybe running tests - that pop up as needed also.

How can you "enable front panel datalogging?"

In the Labview User Manual, it says that "You can create and read datalog files by enabling front panel datalogging." How do you go about "enabling front panel datalogging?"
Any help would be greatly appreciated.

From a LabVIEW only perspective, you can enable control (front panel) datalogging through the menu Operate>Data Logging->. If you bind a log file to the VIs front panel it will generate a binary file with the state of the controls in it, when you execute Operate>Data Logging>Log... (I could not find a way to execute this Log... by VI server programmatically - Maybe someone else?)
From a LabVIEW DSC perspective you can generate a Logos Remote connection to a tag (e.g. with the HMI Wizard). And when you have enabled that this tag has to be logged, the LabVIEW DSC Engine will store/log the value into the Citadel database.
Hope this helps

Open and close a vi front panel dynamically

I created a main vi panel that display all the signal names. I like the main vi to open a new plot screen when I double click on the signal name. I was able to do that using invoke node. But I when I close the plot screen by clicking on the Window "Close" button, the main vi was not able to open a new one again. So I disabled the Window "Close" button and only use the "Stop" button coded in while loop in the blockdigram of the plot screen. It worked, but the plot screen is still open and changed to editing mode. Is there an easy way to close the plot screen by only one click. Another question is that how does the main vi can open multiple plot screens. Thanks for your advice.

I think I know what happens:
If you close the front panel of a sub-vi, the code is still running, so the VI doesn't terminate and somehow you can't address it (it don't know how you communicate with your sub-vi).
So in your sub-vi you should monitor the panel-close event, and finish the code of the VI and finish the VI

Open and Close Front Panel of SubVI

Hi all,
Running LabVIEW 2011 on Windows 7 x64. I am trying to get a subVI front panel to open from my main FP with the press of a button and then close with a button press in the subVI. Here is the piece from my main FP that calls the VI and opens the FP
Plots is defined in another loop and all of the loops are in a flat sequence. I did it this way because I want it to start with the first press and not stop my main loop from running. I have moved the item in the left loop around a lot so I'm not sure if I can run that in the same loop as the event or not. Either way opening the VI seems to work fine.
The problem shows up when trying to close the subVI for the SECOND time. The code is here:
As I said, the first time I open and close the VI everything works as I expect it should. I am then able to open it again but now the "blank button" doesn't function and I can't close the window or even open the block diagram to probe anything. I have been trying to figure this out for awhile, any insite would be greatly appreciated!
Thanks

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

Square root symbol in front panel

Hi,
Thank you all.. I could insert the sqrt symbol in the GUI.
I also want to initialise one of the strings with the same symbol. So I copied the sqrt symbol and inserted that in place of "sqrt(3)" . but it switched back to a special character. I selected that special character and selected symbol font from the font menu, then it switched back to sqrt symbol. but as soon as i clicked the mouse outside, it reverted to the old special character(may be the one corresponding to 0xD3 in Application Font).
How to fix this?

Front Panel Mass Binding Project Variables Issue

Hello -
When attempting to bind controls to shared variables through the front panel mass binding option, there is an issue where you can not seem to bind a "project item" to the control. The method of binding I am using is to export a text list of control names, urls, mode, and function to a text editor utilizing the front panel binding mass configuration options. The text editor shows, in the fourth column, a "0" for no function, a "1" for network item, and a "2" for project item. when attempting to import the list back into the front panel binding mass configuration, all "2" indications become "1", as all items are treated as network. Thus one can not effectively bind to a project shared variable item.
The binding works fine manually by means of utilizing the properties selection of the control, but it is difficult to do this for 821 controls, as in my application.
My application is based on a OPC served group of 821 variables which are linked to controls and indicators through the shared variable representation for each item created in the multiple variable editor.
Does anyone have a work around for this issue, as it is a showstopper right now, ie, you can not effectively bind a large quantity of controls or indicators to project located shared variables as required.
The rationale behind utilizing project located variables instead of network located variables is to reduce the amount of calls to the OPC server which was causnig a large latency in the refresh of the 821 items. With the items defined as shared variables within the project, a single call is issued, which has tremendously sped up the refresh cycle for the list of variables.
Thank you in advance for your insight in this matter,
John DeCroos

Hello Brian A.,
In response to you comment --
"in 2006, and John did not follow up with any more information for Efosa"
-- a great deal of information was provided to NI (Efosa and many, many others, up to the product manager for the DCS module). I have never heard back on a fix for this bug for the identified version of LabVIEW. The reply by Efosa here was well after we had shipped our product -- (please see date + Efosa's apology) -- we had found our own solution as is identified in the original post.
My solution was, as is also indicated in my original post, to manually bind each variable. This was unbelievably time consuming, but was all I had.
The version of software I am now working on uses far less variables, manually bound to avoid the multiple binding issue we had in the past.
I have checked the mass binding function in LV 8.5.1, it works fine now. I guess it would have been nice to have had a reply that the bug had been resolved ---- would have helped me out a bit.
Thank you,
John DeCroos

Reading main VI front panel in SubVI

Hi,
I'm trying to create a subVI that writes a header text file containing info on essential parameters in my measurements. My mainVI front panel has a few dozen controls, some of them contained in a handful of clusters.
What I'd want is just to be able to access and read the values at the subVI to construct the string I want to write to the file.
I wouldn't like to proceed the dumb way, i.e., building an array of clusters or individual controls or references to them and passing that to my subVI (and, obviously not passing each individual control/cluster as a subVI input).
I figured I'd like to have some kind of refnum of the mainVI frontpanel passed to my subVI and dig use a big pile of property nodes to dig out the info that i need, inside the SubVI. Is this a feasible solution and if so, what's the way to conduct it? If not, what would be a better way?
As before, I'm using LV7 so in case you answer with block diagram examples, I'd appreciate screenshots of them.
Thanks,
Lauri

Actually that is the preferred way to do. Why you may ask? It is because you decouple the functionality (creating your log file header) from your specific user interface. By doing so you can reuse this VI in other places or applications. By using the references directly this ties the subVI to the calling VI. Unless the subVI is specifically doing something to the UI itself a subVI should avoid accessing data it needs via direct references. It should require the data to be wired in with the appropriate clusters, arrays or whatever your data needs are.

How to open remote front panel of vi's within an executable from an executable.

How do I remotely open front panels of subvi's contained within an executable, where both computers just have LabVIEW Real Time loaded (programs are run as executables)? I want to use the Method: Remote Panel Open Connection to Server to make this work. I have been getting error 1032 "VI Server Access Denied". I do not want to use the web page method (connection is too slow when controlling front panel objects and I can not programmatically exit out (release control of vi) of the web page).
Ex.
PC1: Has executable1 using Remote Panel Open Connection to Server Method etc. code inside. This program will make a call to executable2 (on PC2) to open up different vi front panels (within executable2), so the controls can be changed from PC1. I want to be able to make changes to the vi's running on PC2 from PC1.
PC2: Has executable2 containing several subvi's.

Not sure if this is what you are looking for but here is how to launch executables that can interact

Conditionally include Front Panel of a Subvi in an EXE

I want to make two versions of an EXE, one "normal" version and a debug version. I know how to set conditional disable symbols via pre/post build actions (btw. NI: these variables should REALLY be defineable per build specification; even bare command line C compilers are easier to use in that regard than Labview).
The "normal" version won't show anything but the main vi. The front panels shouldn't even be included in the exe. For the debug version I want to show the front panels on request (I've queues for sending that to the subvis). Simply calling "FP.open" does not work with an compiled exe, because I get a "resource not found" error (the front panel of the subvi is not compiled into the exe). I tried setting show "frontpanel when called" which forces the FP to be compiled into the exe, but then the FP will shortly flash on the screen, even when the first command of the subvi is hiding the frontpanel.
How can I make a subvi depending on a conditional disable symbol include its front panel into the exe without forcing it to show its frontpanel at the same time?

There are a number of things which cause LV to keep a FP when building. These include things like open when called (which you understandably don't like), but also various things which statically require the front panel. Things like changing the scrollbar settings or creating a property node for a control on the FP. Personally, my preference is for the latter because you can document it better.
If you don't actually mind whether the FP is included, you can just do that and be done with it. If you really do mind, you can check whether placing the property node for the control in a conditional disable structure has an impact on this or not. I have no idea whether it does or not, since I don't know exactly how LV will treat the code in the disabled case.
The other alternative is making two builds and configuring it for each VI:
The disadvantage here is that you have to manage two builds and do this manually for each VI.
If you want, there's a related idea on the idea exchange, but it won't actually help in your case, because it's not conditional:
