HTML preview on front panel

Hi!
Is it possible to preview a text that contains HTML tags on the front panel as HTML?
I'd like to see my html report result before i save it into file.
Thanks
Solved!

Hmm! Thanks!
And how portable is it? Does it work if i build an executable from my project and then use it on another PC? I guess that the only requirement would be the same browser on that machine.
I found an example in LV, using IE with activex. Did you mean that?
Thanks

Failure saving file .html when printing front panel

Hi,

Only if i select black and white on the html printing options i get a file, but i need it in colour. It happneds only with one VI but this failure didn´t use to appeard.
Recently i´ve install labview2011 and this project came from labview2010, which is still on system.
Thanks and excuse my pour and rusty english.

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.

How to display some html code in the front panel

Hello.
I am trying to properly display a few lines of html code in some kind of indicator on my front panel.
I was trying to use an ActiveX container with MS IE in it, but all the methods I find are to make it navigate to a given URL. I did not find any method or property by which I could give it some html code and it would display it.
Anybody know of a way to do this? It does not have to be using ActiveX or MS IE.
Thanks in advance,
Alejandro

Here is a simple way using the activeX that I have embedded in some programs in the past. You will have to call the file path to show the file.
Hope this helps some.

HTML Preview panel - How To

Hi,
Now i am trying to develop a HTML preview panel in my HTML editor.
for the simple html documents I am giving to the editorpane by using setText() function it's working properly.
but if copy some html source from a website and set the source using setText(), it's not working..not even single text or image is displaying.
DOnt know the problem.
What I want to do is. a browser component by which i can display some HTMl content.
Pls help me.

I've already tried that and it doesn't work. In fact clicking inside the document window will deselect any of the found (grey hi-lighted) text.
Now, if I click and drag any of the text in the document, then it will be hi-lighted yellow as specified in the Appearance settings. But it will not be yellow when it is found as part of a search and the thing that's most frustrating is that older versions of Preview (or OS X) had this feature. I can't understand why Apple would do away with it in favor of light grey!

How to add image of Front panel TAGS to html report?

I have a VI with several tabs some of which I would like to append to an HTML report. So far I have managed to include just the front panel front tab (using the Append Front Panel Image to Report.vi. Is it possible to create an image of the tabs in order to append to my report?
I'm using LabVIEW 7.1 on windows 2000
Thanks for any help. It would be greately appreciated.
Eduardo

Hello Eduardo,
In order to accomplish this, you'll need to use the Append Control Image to Report VI in a loop. On each iteration of the loop, programmatically change the Tab Control page (with a local variable or the Value property), then append the tab control image to the report. That way you'll have N images in the report, where N is the number of pages in your tab control.
Hope this helps,

Why does my Web Publishing Tool fail to create an image of my front panel when I select the "Embedded" viewing mode?

I am trying to create an html file for access by a client computer through the LabVIEW Web Server. I want to enable the client to control the vi, so am chosing "Embedded" for the Viewing Option in the Web Publishing Tool. The small preview screen in the Web Publishing Tool shows an image of my front panel, but the resulting html file does not include this image. The Web Server error log shows a 404 error which I believe is due to the lack of an image (or any front panel objects) present in the html file: Error: 404 "Not Found" for "/.lv_frontpanelprotocol.rpvi100", file "c:/program files/national instruments/labview 2010/www/.lv_frontpanelprotocol.rpvi100": Can't access URL
If you are aware of this problem or know any solutions, please post a reply.
Thanks,
David

Does it work if you preview the web page locally?
Does the client computer have at least the minimum 2010 run time engine installed?

Front Panel Controller SubVI?

Here is the scenario, I have a main VI that uses an event structure to call various other SubVI's depending on what control is pressed and to update the front panel accordingly. The front panel of the Main VI is a Tab Control with ~25 controls total. As you can imagine, some controls should not be enabled until other events happen. For example, I have a menu ring called "Report Type" of which you can choose 'HTML' or 'Send to Printer.' Next to this ring is a boolean control called "Open in Browser?" , I want to only enable this boolean control only when "Report Type" is set to 'HTML.' Likewise I want both the "Report Type" and "Open in Browser?" controls to be disabled if the user has not hit the "Download Data" control to get data from the RT Controller (otherwise there would be nothing to report.)
These are just a few examples of what I need to do, I have been adding 'Disabled' property nodes throughout my event cases but it is becoming very unwieldy and making my block diagram quite cluttered and hard to understand. What I want to do is have a 'Front Panel Controller SubVI' of sorts, of which I define about 10 or so various states the front panel can be in and pass that state to the controller SubVI which in turn disables/enables controlls accordingly. This idea sounds good but so far the implementation seems pretty bad. I was hoping I could just make a cluster of control references and pass that into the SubVI but LabVIEW 8.2 doesn't seem to allow me to wrap up references in a cluster. This has forced me to use VI Server to get the references. What I've been able to come up with using VI Server works, but I can't believe its the most elegant solution. Basically, for each of the possible states, I iterate over all the controls in the front panel and have a case structure for their Label Text which determins if that control should be enabled/disabled for the given state passed in. Also, for some reason it seems that it is not grabbing references to ALL of my controls. There is a menu ring control on the front panel that isn't in the Controls[] array. I should mention that this particular Control already has a reference node created for it that gets passed to a SubVI, perhaps this is why its not found in the Controls[] array, but this doesn't seem to be very intuititve, or documetned for that matter.
<a href="http://tinypic.com" target="_blank"><img src="http://i37.tinypic.com/fjgwtv.gif" border="0" alt="Image and video hosting by TinyPic"></a>

Thats a very good idea, although I'd probably want to put a case structure around the disable property node and have it only change value when the search array function does *not* return -1, otherwise I'll be disabling things I might want to maintain in an enabled state.
Just before I read your post, another thought came to me and that why use a SubVI, I could just use a parallel loop with queues to send back state information. Since queues can be blocking, this would not negate my event structure. I could combine the idea you gave me with this architecture. Thanks

Print VI front panel to file does not work after building executable.

I am using a property and invoke node to print the front panel of my VI to an HTML file. It works fine in the development mode. After Building the application, this subvi will no longer
print the front panel. Is there some special files that included in the build??

You can use the Report Generation VIs to generate the HTML report. Specifically, you could use Append Front Panel Image to Report.vi and Save Report to File.vi to save the image of the panel to an HTML report.
Check out the examples in examples\reports to get a better idea how to use these VIs if you've never used them before.
Good luck,

Append front panel image crashes in 7.0

I'm trying to use append front panel image.vi in
Labview 7.0 and when called Labview crashes in the
standard report case calling invoke node for IReportData > AppendPictureFromFile. Labview just
quits. What's weird is it appears to work on a
system w/ a local printer but not one w/ a network
priner. Any ideas?

try to generate an HTML report first, and then print that. Some printers are worse than other at printing (what looks like) a simple object.
Otherwise, I would do some basic trouble shooting, like can you print a simpler front panel image (say two numerics) to the printer. Next, I would try to print to a different networked printer.

Screen capture of the front panel automatically

I've got a VI that analyzes a data file and outputs a graph, some numbers/notes, and a pass/fail message to the front panel each time we run it. I want to be able to automatically save all that data into one easy-to-access file (no html) after running it, and ideally this would be accomplished by just capturing the screen of the front panel and saving it as a .jpg.
I've looked up how to do this on the forums and searching the web, but no solutions have come up. I've looked at the "Get Image" method, but that only lets me get the image of one object in the front panel, and not the entire front panel screen. I read something about referencing the front panel as an global, and inputting that into the "Get Image" method, but I can't get that to work and don't know if that's possible.
Is there a way to make a straightforward automatic screen capture of the VI front panel? How can I program that? (Manually using the "pinrt screen" function off the keyboard and copying and pasting it won't be feasible for this application).
-- Thanks for the guidance

No sure why you couldn't find a reference to it but there is the VI method Get Panel Image.

Front panel not aligning properly on scale print

So I've created a custom print VI with various graphics that I'd like to print on an 11x17 sheet of paper in landscape mode, but for the life of me I can't get the thing to align properly. I want the front panel to print centered with 0.1 - 0.2 inch margins all around, but instead of doing this, the front panel will sometimes print aligned to the left and top or other times to the right and top (with wrong margins always on two sides, sometimes three or four). I'm using a programmatic call to the easy print function that scales the front panel to fit on this size. However, even after making the proportions of objects on the VI 11:17 (vertical: horizontal) I still can't seem to get this thing to center properly. Any ideas of what the problem could be?

Ok, So I created a blank VI with a 1280 x 1978 frame decoration, yet the print preview in labview still doesn't seem to show the thing with proper alignment.
Looking at the picture, looks like it's aligned along the right and top of the page rather than uniformly centered. Ideally, the frame would uniformly cover all the edges around the page in the preview. I suspect this is an issue with LabVIEW and not my printer, as I can set my printer to borderless printing.
Any ideas?

Problem Printing Front Panel

I'm having a problem printing the front panel of a particular VI. When I set the print option to Standard Printing the printer prints nothing. When set to Bitmap Printing it works, but it's not the type of printout that I want. In both cases the Print Preview appears the same. Also, all my other VI's print in Standard Printing mode with no problems.
I've read other posts indicating that the cause may be that the VI is sending a print code to the printer telling it not to print. How can I determine if this is the case? If it is the case, how do I fix it? This VI's front panel has nothing special about it relative to other VI's that print correctly.
Any help would be greatly appreciated.

If it happens using the menu, then it's not that your code sends a "do not print" action to the printer.
Try copying front panel items, one or two at a time, from your wonky VI to a new VI, and print the new VI after every move.
Maybe you can find one item that causes it.
If you're on a Mac, print it to a PDF file, and see if that's OK. If you're on Windows, you can use Print2PDF or something similar to act like a printer and show you what the printout would be.

Front panel doesn't print

I am trying to print my VI. I can see the front panel in Print Preview. When it prints the front panel page is blank. Anybody else run into this problem and how did you fix it.
Thanks
Chris Gallo

Are you using any decorations on the front panel? Perhaps drawing a border around the panel?
(Reason I ask is that I once had a border decoration print over the controls it was supposed to be behind. I'm not sure what happened, since I could access the controls while running the VI, but for some reason, when I went to print, it thought it was in front of the controls. After selecting the border and sending it to the back again, it fixed the problem.)
