Wireless indicator on front panel blinks

HP Pavilion m940f. Wireless light on front panel blinks when booted on Windows 7 drive. Works fine, steady on, when booted on Windows Vista hard drive. What am I missing in Windows 7 to make it work properly?

You're not really doing anything wrong. The method involves a "trick" and is somewhat limited in what you can do.
You cannot place additional controls or indicators after you "Then I right click the chart and tell it advance and customize", however you can modify the existing object. The trick is that certain objects have more than one display (e.g. a chart or a thermometer, etc all have digital displays).
So (in the control editor)...
right-click on the chart and select "visible item...digital display"
Now you have your second indicator that you can modify.
right-click on the just created "digital display" and select "replace", and e.g. replace it with a thermometer.
Now right-click on the thermometer and select "visible items...digital display"
replace the digital display of the thermometer with a gauge.
make the digital display of the gauge visible
replace the digital display with yet another indicator...
etc.etc.
Save
All clear?

Placing indicator on front panel in front of control

I would like to put a transparent control on top of an indicator on the front panel, but the control ends up on the bottom. How do I make the control appear in front?

Right click on the control then to create - > node of property.On node of property click right then to change into any writing then it is enough to connect true so that the control is visible false invisible.Create a rocker between the two controls and the turns and played

Print only a specific control or indicator on a front panel to HTML document

Is there any way to print a specific control or indicator (not the whole front panel) to HTML document? I am trying to print a report that has a graph and some indicator value on it.

There is a VI called "Append Control Image to Report.vi" which will allow you to do this. It's located in the Functions>>Report Generation pallette. Take a look at this and see if it's what you're looking for.

HP 6500 wireless ALL-in-one e709n Printer front panel not responding at all

Hi there,
I have got a HP 6500 wireless ALL-in-one e709n printer.
I have been using it with my pc with windows vista on it for nearly 2 years and it has been great.
1 month ago, the front panel of the printer stopped responding, ie, when i press any buttons, the lcd screen on the printer does not change, it always show the ink level.
The printer turns on, shows that its preparing, then goes to idle state with ink level icons on the screen.
If i try to print any documents, it works with ethernet cable connected to my pc (which i used to do it wirelessly) , the cable-connected printing function still works, but wireless printing does not work anymore.
However if i try to scan something, on the pc when i open the hp scan app, it shows that 'scanner is not available'.
Also because the front panel doesnt work, no buttons respond, i cannot scan or copy.
I have tried unplug everything and reinstall all drivers and programs.
No damage to printer or my pc, it just stopped working all the sudden.
Can any one help me out please?
cheers,
Charlie

Maximum Character size of Front Panel indicator in LabVIEW

Hi,
I have a simple question that I hope somebody can answer. Is there a maximum character size that can be displayed in a Front Panel indicator in LabVIEW? If so, what is it? I have a VI that is continuously reading a serial port and updating a front panel indicator, and I need to know how much text can be displayed before it either truncates or throws an error. This is for LabVIEW 2010 SP1.
Thank you,
J Korn

A quick Flatten to string shows how LabVIEW stores strings {size-data} Size is a U32 so 4294967295 characters max.
The big thing to remember is this memory must be contiguous (and the Indicator requires a COPY) so in practice the performance hit for constantly allocating larger and larger buffers for the data and available memory impose practical limits much lower than the 4294967295 Char maximum. Probably better to log the data to a file and maintain only the last x characters on the indicator and use the file to look a history data

Picture Indicator slows down front panel

Hello folks,
I would like to use the picture functions vi's to draw alot of dots on a bitmap.
Problem is, that after a certain amount of dots (>10k) the vi starts to slow down if I show the indicator of the picture.
However when I use a picture to pixmap and then redraw the picture from the pixmap the front panel indicator doesn't slow down the vi at all.
I would be very grateful for a more elegant solution to this problem other than redrawing the picture from a pixmap.
Best regards,
Mark

Mark,
When the image has more datapoints than the image has pixels or when the new image overlaps part of the old image, things can slow down.
But I suspect that the real problem is the re-allocation of memory as the picture string grows. Open the Draw Point.vi and Set Pen State.vi block diagrams and you will see that each of them does a Concatenate String operation. Strings are stored in memory as a 4-byte length and an array of characters. Like any other array, the string elements must be in contiguous memory locations. So, as the string grows, frequent memory re-allocations must occur. This can slow things dramatically. The way those picture VIs are built there is no way to effectively pre-allocate the memory.
I do not know how effective it might be, but you could rewrite those VIs to use arrays of U8, Initialize Array, and Replace Array Subset, followed by Byte Array to String. Then only one memory allocation wold be required.

Centering Label Text over front Panel Indicator

How can I get the Text in the Label of a Front Panel LED Indicator Control in LabVIEW 2009 to be centered over the LED?
How can I change the Font an Font Size of the Text of a Label?

Hi,
Label to be center at the object.
There are many Ways like
1) what the JackDunaway has explained Text Settings Toolbar button.
2) Other you can dynamically change the property of label.
Like you can change programmically change label justification, size, color, and many property.
Just right click on object.Go to creat property node. refer screen shot for more help.
Thank you.

Update a front panel indicator from a loop inside a called vi. Without exiting

I am looking for the best way to update some indicators from within loop within a called .vi.
I need to update the front panle without exiting the loop.
I am able to use functional global vi to update the values of front panel indicators from within my nested loops, but I am looking for the best way that these values can be read to update my indicators.
Thanks

Or a cluster of references, that way each reference can be named, and can be different types to match the respective indicator.
There are also methods where you can just send in a VI reference, and in the subVI traverse all the controls and search for the appropriate references by name.
Take a look at this long nugget.

Imitate boolean switch behavior using an event structure on a front panel indicator

Hi,
I am looking for a possibility to imitate the bevhavior of a boolean switch with an event structure. To be more precise, I want a boolean value to change each time I click on the front panel indicator and then remain constant until I click again. I have not worked with shift registers in a while loop yet, but could this be a way to find a solution?

LordSnow wrote:
Okay, I figured it out, BUT I still have a problem. Before I first trigger a mouse event on the front panel indicator, I already need the case structure to be executed once. Therefore I assume that I need some kind of default value, but since the event structure does not create any output at first, I have no idea how to do that.
Are you talking about the shift register you just created? You can while in a default value on the left shift register ndoe. It is wired outside of the loop.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Saving text written in a string indicator on the front panel

Hi,
As a new LabVIEW user I'm trying to type a manual to explain how to use the software program I'm writing. I would like to display it on the front panel in one of the tab windows. There is quite a lot of writing and I would like the user to be able to scroll through the text. I tried inserting a string indicator, right clicking on it and selecting 'visible items'>>'scrollbar'. However, when I saved my changes the writing in the indicator was not saved with the rest of the changes. I'd be grateful for any advice.
Thanks,
Adrian

Adrian,
The 'data' in your string indicator was probably not saved as 'default', so that when you closed the VI and re-ran it, it was lost.
For any data (strings, numbers, etc.) that you want to have as default, you will need to rt-click the indicator/control and under data operations, select 'make current value default' (when you have the data entered).
Also - add an Invoke node function to force this indicator to display the default data upon initial running of the VI.
Another way, though, when you have a 'lot' of text, is simply save your info in a text file, and have a VI open the file and display it either as the text file itself, or as input into a string indicator.
Good Luck, Doug

Valeur indice tableau affichée dans le front panel

Bonjour à tous,
je cherche à avoir la valeur numérique de mon indice tableau qui est affichée sur mon front panel.. et non un tableau 1D d'indice
Cordialement

Excusez-moi, je pense que comme je suis en train de coder, cela me paraissait bien évident..
Je trace un profil sur un graphe XY à partir de données dans un tableau de cluster.
Lorsque l'utilisateur rentre ses données et clique sur suivant et bien, cela lui trace la portion de graphe associé.
C'est pour cela que j'ai besoin de l'indice de mon tableau de cluster..

How to change front panel indicator properties such as background color or enable/disable programmatically?

Is it possible to change the properties of a front panel indicator such as background color or to change from enabled to disabled-grayed out programatically in response to limit conditions or a time-out?

"Disabled" means that the control/indicator will not respond to a user operation. However, the displayed data can still change. What you want to do can be easily achieved using a case structure : wire your boolean to the case input, and put your indicator in the "True" case condition. That way, it will be updated only when the digital input is set to true.

Printing front panel of VI - no borders appear around the indicator box values

Dear readers,
I am using Labview 6.1 on a pentium PC with adequate memory etc. I've been trying to print out the front panel of my VI using a postscript printer and the post script printing options available in the Labview. I notice that the printed front panel doesn't show the rectangular borders that is supposed to surround the values contained in indicators and controls.
Apart from this problem, everything looks good, such as it prints out in the way that I want...with nice white background to not waste ink.
Could someone please advise me on what options to set up in order to print the borders around the indicator box values? Thanks very much for any help.
I noticed that for
an older Labview for the apple Mac, namely Labview 4 for the Mac, you can just print the window of the front panel and everything comes out wonderful....you get the borders around the indicator and control box values.
Thanks again.
Kenny Leong

Hi Mike!
Thanks for replying to my post. Greatly appreciated. Is it possible to set the colours for the indicator edges? I'll attach a screen capture of my front panel, and also a digi-pic of the print out. The printout is ok except there's no borders around the indicator values. I printed it out on a hp laserjet 6MP printer as well as on a hp 4050 printer and the printed panels have no borders around the values. I'll attach my front panel vi too. Thanks a lot Mike.

View Cluster Control/Indicator as Icon on Front Panel (sub VI's)

I make a lot of use of clusters to pass data into and out of sub vi's. I keep everything typedef'd and the clusters can often grow to be rather large on the front panel which makes navigating the front panel quite difficult. I usually have maybe 2 or 3 other controls and indicators that are not within the cluster.
Is it possible to view the cluster as an icon in a similar way to the block diagram?

Hello DNichols,
I recommend placing the cluster(s) in question partway off-screen, with the label displayed. If you really need to minimize the footprint of the cluster front panel object, set AutoSizing to "None" via the right-click menu and resize as needed, but keep in mind that the FP object is now more-or-less useless to future developers except for ease of clicking to link to the connector pane. Since you're type-defining everything, accessing or viewing the contents of the cluster might not matter much, though.
Redefining your architecture is probably not a priority right now, but you might also want to consider using classes in the future, as others have suggested.
Regards,
Tom L.

I built an application to store de front panel of vi in a JPEG image file, but native labels of controls and indicator are unclear after image capture, some one knows why? I have a working example you can test.

For some label colors like yellow or green, this defect is almost invisible, but for black color or any dark tone like brown or dark gray after file creation appears unclear labels.

In more details, JPEG uses lossy compression and is not really suitable for cartoon-like pictures with objects containing high-contrast sharp features such as lines and boxes (as found in front panels). This has to do with the truncation in the 2D cosine transforms which gives you weak ripples near sharp edges, not visible in typical photographs.
Of course you could set the quality to 100% (optional input) for no truncation with a trade-off of larger files, but it's pretty pointless. JPEG is only meant to be used for photographs.
PNG is a fantastic format (intended as a GIF replacement), uses lossless compression, and wins in all aspects over jpeg for your intended use. All modern applications can deal with them (e.g. you can insert them into word or powerpo
int) and any modern browser can display them. (see e.g. the PNG home site for more info).
