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 do you select a sub-set of cells from the entire document so you can print only those specific cells?

There is no analog to MS Excels print range. So the next best thing is to plan your data so that you don't need to use print range. The next best thing after that is to select the range of cells you want to print, then copy, the switch to the application Preview, and create a new document from the clipboard (select the menu item "File > New from Clibboard") then select all, copy then paste to the destination (maybe an email) .
You can also paste that portion of the table into another table (or a new table) by pasting values only

In printing only a specific selected section, the top line or 2 of the printout is not printing. This only happened since the last update. It does not happen when I use internet explorer.

I read many financial documents during the day. I sometimes print only a selected segment of an article or a financial statement. When I print selected only, the top line or 2 lines is omitted from the print document. It does not happen in explorer.
I used Firefox for years, and this just started in the last 3 weeks or so. I can get around it by just selecting 2 lines above what I want to print. But, it is annoying.

Check and tell if its working.

How to find VI's connected terminals when controls are hidden on the front panel?

When working with a sub-VI which has terminals connected to hidden controls is there a straight-forward way to find the terminals on the block diagram?
I click on the terminal and an outline appears on the front panel but when I try to click on that outline I can not unhide the control.
The only way I have discovered to find the terminal of the connected control is just check each terminal on the block diagram which looks like it might be connected.
I'm using LV7.1 but also use 8.5.
Thanks,
Davey

If I understood the premise of the question it sounds like you have controls/indicators wired to the VI connector pane, but for some reason these controls/indicators are hidden. If this is a VI you wrote slap yourself. If this is a VI someone else wrote, go slap them.
One way that you can find the terminals on the block diagram by performing a search by text. The context help will show you the names of the controls/indicators. The only problem with this approach is that if the control/indicator has the caption visible rather than the label, then the context help will show the caption, not the label.
Another method is to use scripting. Not sure if it's worth the effort for just one VI, though.
Before we get all slap-happy I have to ask...
If I have a sub-VI which is set for Print on completion and the controls in/out for the icon connector are NOT supposed to show up on the final report, isn't setting those objects as hidden a viable option?

Well, of course, Ben. My comment was not meant to be taken seriously... hence the smiley happy icon. To respond to your question in a more serious matter, though, there's always exceptions to rules. That's why they're rules - they're meant to be broken. Otherwise they wouldn't be rules. It's a strange state of the universe, isn't it? Although, one could probably just place the control behind another object. That sort of hides it, doesn't it?

How do you control LED lights on the front panel to identify the number of steps a stepper motor has taken?

I am controlling a stepper motor that is coupled with a valve with four outlets (using an Arduino). I've got a general understanding of how to control the motor, but I want LED lights on the front panel to light up that indicate which outlet the valve is currently at after the steps are taken. The method I'm thinking about involves a lot of repetitive code. I'm not that experienced with LabVIEW, I'm assuming I need some sort of loop structure but I don't know how to set it up in order to control the sequence of the LEDs. I've attached my current block diagram for a visual aid if needed.

I was thinking about using the Stepper To Go and Stepper Write functions four separate times, using the same constants for the steps each time since the distance between each outlet is equivalent. The only difference would be what's connected to the "steps remaining" node, which would be the function that activates one of the four LEDs (if that makes sense). I was thinking that doing it this way would be a little counterintuitive since the only thing that needs to be changed is the LED indicator.

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.

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

Controlling the load order of swfs in a HTML document

Hi all I have a document containing multiple swfs. Is there
anyway I can control which swf loads first etc. Obvisouly it would
start from which ever one is higher in the HTML document.
However I would like to control what loads first, also can
this be done with the images in the document?
Any help is much appreciated.

In your web.xml, under the servlet tag, make A.jsp be loaded the first, at your web app 's startup:
<jsp-file>A.jsp</jsp-file>
<load-on-startup>0</load-on-startup>

How do I group a large logic circuit into a single icon that still allows for control of that VI's front panel?

I have a graphical representation of a P&ID made of LED lights that turns green or red depending on if that
process line is open or closed. The coorisponding block diagram is a rather large logic circuit that controls
these LED lights.
My problem is that I want to essentailly block that large piece of code into a "Sub VI" but I still want to use that
code to control THAT VI's front panal. This would allow me to, in the future, make an automated sequence that can
still use this light show without opening another VI's front panal.
If anyone has used Simulink this is the exact same thing as its grouping function...

Are you asking how to control the front panel of one VI from the front panel of one of its subVIs (or another VI)? Is so, check out VI server. VI server functions are found on the Application Control palette. For a short demo, right click on one of your controls and select Create»Reference. You will be switched to the block diagram and have a reference node attached to your cursor. Drop it. Now go to the Application Control palette and select and drop a Property Node. Connect the newly created reference to the Property Node top left terminal. Click the Property Node's Property area and scroll down to the Value property and select it. Right click on the Value and select Change to Write. Wire a value to this input and it will change the value of the control. You now have a method that allows you to change the value of a control from another VI.
Some caveats. This can be slow. It is synchronous, meaning that the function will not return until the front panel has been updated. If you want to do a lot of controls at once, use the VI property Defer Panel Updates to turn updates of the front panel off while you are writing to it. Don't forget to turn it back on. If you can use a terminal or local variable, do not use the Value property.

Printing Only A Specific Selection

OK, so one of the things that has really bothered me about Safari is that I cannot for the life of me figure out how to only print a specific selection in a certain webpage. On a PC, I just hit ctrl+p, and I can easily click "Print Selected", so it only prints what I've highlighted on the page. How do I do this on a webpage on a mac in Safari? Thanks!!

Here's another excellent plug-in that adds a Print Selection menu item to the Services menu of Safari.
http://www.versiontracker.com/dyn/moreinfo/macosx/24202
You can also try this. Select the text you want to print and go to Safari->Services->TextEdit->New Window Containing Selection. A new window opens with your selection in it and you can print from that window.
Explore the Services menu after you have selected some text and you will find a bunch of other options available to you. The Services menu is available to any OS X application that has been properly written.
Oops. Double post. Sorry about that. I wish we could delete posts.

Specifically controlling the width of a table in an HTML report

I am generating an HTML report that consists of several detail tables
followed by a summary table at the end. Each detail table is
generated within a for loop. The summary table is generated
separately at the end. The detail tables all have the same column
width and same number of columns. However, I cannot get the summary
table to have the same column width even though it has the same number
of columns and the same column width setting.
Does anyone have any suggestions?
Thanks!

Hi,
What VI are you using to create the tables using the for loop? What VI (Append Table to Report.vi?) are you using to create the table at the end?
If you are using the Append Table to Report.vi to create the tables in the for loop, can you change the width of the columns and see expected behavior?
Let me know, and I should be able to help you out further.

Is it possible to sort the controls and indicators on the front panel?

Programming events would be much easier in an application with lots of
controls and indicators, if there where a means to sort and group them.
Is there any means to do so such that you see a sorted list when choosing the control that triggers an event etc..?

I am not aware of a way to sort the list of controls (that are listed in the edit events dialog) by name. They seem to be sorted in the order they were created.
I agree, sorting could be useful for large VIs.

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

Remove print only water mark

Create a pdf and then goto to the document menu and select add water mark. Set the water mark to only show when the document is printed. Add some text for the water mark. Save your document and close it.
Now open it backup and do a print preview. You should see the water mark in the preview. Cancel the print. Look at the document on the screen. You should not see the water mark when viewing on the screen. This all works.
Now how do you remove the watermark? There is no option for removing the print only watermark.

This assumes that you have the ability to edit the document.
Go to Advanced>PDF Optimizer...
Select "Discard Objects" from the left window panel
In the "Discard Objects Settings" select the check box "Discard all comments and form widgets"
Click the OK button
Rename the PDF to something else
Click the Save button.
Cheers!

How do I load a print screen image into a picture indicator?

Hi,
I am trying to load a printscreen image into a picture indicator without first saving it. I am currently doing it by acquiring and saving a print screen image, then reloading and displaying the bitmap file. This works, but it is not elegant and the colors are displayed wrong. (The SnapView.vi is from the G Toolbox for LabVIEW) Thanks for your help.

Hello –
When you push the print screen button in your keyboard, the image is send (temporarily stored) to the clipboard.
You could call the Windows API to recover that image and send it to an indicator in the front panel. This Example Program can show you how to make Windows API calls; I think you might find it useful to get started in programming your application.
Hope this helps.
