Using the invoke node VI Strings.Import

I'm achieving a program to translate the captions which are on the front panels of existing programs.
I use the invoke node VI String.Export to create a file containing the differents properties of the front panel objects of the target VI.
I modify the fields <CONTROL ID .... name="xxxxx"> to change the captions and then i use the invoke node VI Strings.import to uptade the target VI.
Then i use the invoke node VI Save.Instrument to save the modifications.
The problem is that the Log File created by the invoke node VI Strings.import indicates me :
Parsing error while importing strings
to traduction_1.0.vi
from C:\Documents and Settings\Administrator\Desktop\work\Labview\Exos\traduction\Vi_import.victl
Tue, May 16, 2006 9:43:20 AM
Error occurred while parsing for String object. Control name does not match.
Which means that it can't change the captions name.
Do i badly use the invoke nodes ? Do i have to use an other function?

Apparently you are changing the control label, not the caption. If you created a caption for the control, the caption value should appear in the <PARTS> body, nested into the <CONTROL ...> tag.
You can't change control labels this way. Labels are used to identify the control to which you are applying changes. Changing the label would cause the control not being found.

Understanding the Invoke Node

In the past, to create some organization, I would create some VIs and then call them from other VIs just by running it as a sub VI where I might pass it a value and the Sub-VI might return a value. Pretty basic stuff and honestly, pretty useful.
However, now I have discovered the subpanel and would like to use it in conunction with other VIs. To my understanding, in order to run and pass data to and from the VI being run in the subpanel, I need to use the invoke node. I'm a little unsure on how to use them though. It's not real clear on how I can pass data to and from the subpaneled VI.
Any help on suggestions or explinations would be great. Thank you.
Solved!
Go to Solution.

I would be repeating what crossrulz said...
However, I suspect you were trying to say "Property Node" and maybe using a reference...
A large influence will be how you are calling the sub-vi in the subpanel. Can you show us part of that code?
EDIT: I just saw you reply..
You can use the "Find Examples..." inside the help menu. There must be 10,000 examples of Queues & Notifers in this forum. A simple search should provide lots of hits. These are easy to implement. Much easier than it appears..
To learn more about LabVIEW, I suggest you try looking at some of these tutorials.

How can i save the output array of the invoke node "commands values" into a specific file

I must save the setup of vi commands'. I use an invoke node called "command value" wich give me an array with the name of the specific command and his value. How can i save this array into a specific file to load it later if o need. Must i change the array format?
Thank you

Hi,
I have attached two VIs.
The first one "Ecriture fichier tableau" (writer) permits to collect all control's values in an array (dbl) and to save it as .bin file. You had to convert variant type into dbl type. (You can do the same with string type if you wish. You will save datas as .txt file for example)
The second VI "Lecture tableau fichier" (reader) permits to retrieve all the datas you saved in the file.
I think this responds to your question.

How do I use the event.target.name String with an external dispatchEvent?

...I hope the title question makes sense...
On my stage I have an externally loaded SWF with a button. When clicked the button dispatches an event to the main stage.
On the main stage a listener then loads an SWF into a loader called gallery.
The gallery loader is also being shared by buttons on the main stage which use the event.target.name String to call in SWFs with corresponding names.
I am using Tweens to fade-out and -in content to the gallery when a button is pressed.
Loading the SWFs was working until I tried to create a universal button function for the dispatchEvent buttons...
The problem I have is that I don't know how to define the String to tell the newSWFRequest where to find the SWF when triggered by the external buttons.
(I may be doing this all wrong... but figured the best way to load an SWF on to the main stage from an external SWF was by using dispatchEvent??)
My code triggers the Event and the gallery loader fades out, but then it cannot find the new SWF:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
Please can someone help me understand the way to make the String point in the right direction? (I think the only errors are in bold below)
Code:
var myTweenIn2:Tween;
var myTweenOut2:Tween;
var nextLoadS2:String;
// Listen for external event dispatched from external btns
addEventListener("contactStage", btnClickExtrnl);
function btnClickExtrnl(e:Event):void {
nextLoadS2 = ?????
myTweenOut2=new Tween(gallery,"alpha",None.easeOut,gallery.alpha,0,0.2,true);
myTweenOut2.addEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteF2);
// Btns Universal function
function tweenOutCompleteF2(e:TweenEvent){
myTweenOut2.removeEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteF2);
myTweenOut2=null;
    var newSWFRequest:URLRequest = new URLRequest("swfs/" + nextLoadS2 + ".swf");
myTweenIn2 = new Tween(gallery, "alpha", None.easeOut, gallery.alpha, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
Thank you.

That works – thank you!
I'm now using this code to fade in each of the SWFs:
function contactStage(e:MouseEvent):void {
    var newSWFRequest:URLRequest = new URLRequest("swfs/"+e.currentTarget.name+".swf");
    myTweenIn = new Tween(gallery, "alpha", None.easeOut, 0, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
But I cannot add the fade out function. I have amended the above code to create:
var myTweenOutX:Tween;
var myTweenInX:Tween;
function contactStage(e:MouseEvent):void {
myTweenOutX=new Tween(gallery,"alpha",None.easeOut,gallery.alpha,0,0.2,true);
myTweenOutX.addEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteFX);
function tweenOutCompleteFX(e:TweenEvent){
myTweenOutX.removeEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteFX);
myTweenOutX=null;
    var newSWFRequest:URLRequest = new URLRequest("swfs/"+e.currentTarget.name+".swf");
myTweenInX = new Tween(gallery, "alpha", None.easeOut, 0, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
But get this error:
ReferenceError: Error #1069: Property name not found on fl.transitions.Tween and there is no default value.

How to use the same OC4j server with different port number

How to use the same OC4j server with different port numbers..?
I have to OC4J installed on my machine on different hard disk drives....
I want to be able to run both the server simultaneously..?
is it possible ..it yes then how..?
for that i have changed the port number of one server...
but when i am trying to start the other server with different port number..it says that JVM -Bind already...
Is there any clues...?
Nilesh G

In the config directory:
default-web-site.xml: Change the port the HTTP listener listens on
jms.xml: Change the port the JMS service listens on
rmi.xml: Change the port the ORMI listener listens on.
Or, you can add another web-site.xml file, and deploy your applications to 1 server, and bind the web applications to the different web sites. This way you only have to deploy your applications to 1 place.

Is it possible to use the value of a string to reference a component in the

I'm fairly new to Java so this may be a stupid question!
Is it possible to use the value of a string to reference a component in the code? For example in the code below, Wall is a class holding 3 different arrays. The Robot class has an array called finishBricks. When the buildWall method is run it receives the integers width and height which are used to construct the dimensions string. I want to use this string to then load the appropriate Wall array into the finishBricks array.
I hope this makes sense! Any help would be greatly appreciated!
class Robot {
public double[][] finishBricks;
public void buildWall(int width, int height) {
Wall w = new Wall();
String dimensions = "Wall" width "x" +height;
this.finishBricks = w.xxxx; // where xxxx is replaced by whatever the String dimensions is

Is it safe to use the Belkin power strip with USB ports to charge my iPad? Or is the iPad USB adapter the safest route to take when traveling with device?

Is it safe to use the Belkin power strip with USB ports to charge my iPad?
Or is it better to travel with the Wall Charger provided with iPad?
Concerned about safety of the device. Thanks for your thoughts.

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

How to name a new Excel worksheet using an invoke node??

I want output from my specific labview code to be written to a new and specific worksheet (meaning I want to provide the specific worksheet name) of an Excel spreadsheet my LabVIEW code will generate. My code will run in a loop where I want data that is generated in each pass of the loop to be written to a new worksheet each time through the loop. I know how to do this if I am ok with just having each worksheet be named 4, 5, 6, etc (on top of the 1, 2 and 3 that comes standard with a new Excel spreadsheet) but I want more meaningful names than just those numbers... So how do I add a new worksheet and give it a name of my choosing??? Also, when right click on an invoke node and then click on "Help for Item" which is right under the Methods selection that comes up, nothing happens, meaning I am not directed to any help file. I see that same behavior under LabVIEW 6.1 and also under LabVIEW 7.1. My guess is either I didn't buy some option required to have that help area be populated or I had it as some option but didn't know to install it when I originally installed LabVIEW??? Having that help available might help answer the question I pose above... I find working with ActiveX components to not be straightforward. Granted I haven't done it much and what I have done has been sort of follow examples and get it to work... But on this naming a new worksheet I have found no useful examples. My guess is it's easy but I'm clueless... Any help would be much appreciated... Note, in case it matters, I do not own the Report Generation tool/capability... thanks... bob...

Hi, Paris1:
Take a look at "Excel Workbook Properties", that is located in
REPORT GENERATION
-> EXCEL SPECIFIC
-> EXCEL GENERAL
-> EXCEL WORKBOOK PROPERTIES
One of its outputs is "Current Worksheet Name".
You can insert a ExcelWorkbookProperties VI in a blank VI and then double-click it.
You will se a rose vi named Excel Get Properties
And inside it (double-clicking it), the way Worksheet's name is got. If you "Change to Write" that property node, you can set it's name.
This way is very complicated, it can be done faster, but this way you can see a process to do that, and checking it, you can build your own excel VIs to do specific tasks.
Hope it helps,
Aitortxo.

DB tools open connec.vi Invoke node connection string broken

I'm running an old version of LabVIEW (LV7.1) on my PC (I have no choice - I have to maintain this one application in this specific legacy version, due to maintiaining consistency with another plant running the same app). Anyway, we are running it on a Win 7 (64-bit) Office 2010 PC. I'm gettting errors related to database connectivity, so I just created a new VI, just to take a look at the db connectivity by itself. When I create a brand new VI, and just drop the DB Tools Open Connection.vi function into it, I get an error "SubVI 'DB Tools Open Connec (String).vi': subVII is not executable". After digging down, I get a "No properties" error on the Property Node. If I click on the connection string, I get "No Properties". Any ideas?

I am trying to remember but i think in newer versions of Windows (especially 64bit), the ADODB library was modified, which broke all of the database VI's in older versions of LabVIEW. I would recommend going back to an older version of Windows if you must continue using LV7.1

Help comparing the value of a button using the Property Node (I get a variant)

Dear Sirs:
(I'm using LabView 6. I guess the solution is different for 6.1)
Currently I have created an array of Boolean RefNums (which point to many, many buttons). When I need to know when any (and which) of the buttons was pressed I just compare every element on the array with the constant TRUE. It fact, as the array is built from RefNums, I should compare the VALUE from the Property Node.
The problem here is that the Property Node for this type of Boolean is a LV Variant, and I need to compare this with a TRUE/FALSE value.
I tried to convert the TRUE constant to a LV variant and visc. But nothing works... I always get that none of the buttons was pressed.
Here it co
mes the question: "How can I compare the value of a Property Node for a Boolean (Button) with a TRUE (or False) constant?"
BTW, maybe I should explain why I'm using RefNums instead of the direct values: As my project requires tons of buttons, I would preffer using RefNums to refer to them. (I.E. I could use a single VI that takes the RefNum and formats the button to hide it for certain users).
I have enclosed a VI that contains what I've achieved until now, which is nothing
I appreciate your time and help.
Best regards,
JAVIER VIDAL

Javier,
There is another problem in your code: the booleans are not polled by the main loop so they will remain false until the user presses them again. This renders the boolean latch action useless.
What you can do is to change the mechanical action of the booleans to non-latch. When you detect a "true" in the polling loop, set the boolean to false again. One added benefit is that once all boolean are non-latch, the value property won't be a variant but a boolean so conversion is no longer needed.

We do not have any DAQ cards within the PC. We have the parallel port which is EPP and ECP compatible having the address 278h on LPT2 and we are trying use this port for reading 8bit data from an external circuit. We developed a vi program in Labview 5.0 to control the parallel port.We tried with the Data lines to send signals from PC to external device through this parallel port with the addr
ess 278h (which
is Data lines) and it works fine. We also tried using reading 4bit data from external
device to PC through this port with the address 279h (which is Status lines) and it
is also working fine.
But it was not possible for us to read through Control lines whose address is 27Ah. Whereas when line printer (dot matrix printer) was
connected, it was possible for us to take print out. Thus printer was working. This
informed us that the control lines are all OK!
Can you please clarify, how to use both control lines and status lines to read 8 bit data through this parallel port using the Labview software.

There are several Knowledge Base entries about this on the NI site, but probably the most detailed document is on the Advanced Measurements (www.advmeas.com) website. Try looking at this page, I think you will find it useful.

I really don't know DDE very well. It is usually recommended that you switch to using ActiveX. You may not be correctly configuring the netDDE server. There is an example in the reource library that shows how to do this. You may also want to look at the DDE advise examples that came with LabVIEW 5.1 and earlier.

I don't know how to use the property node to get information out of my sub vi while it is working.

I had a question answered earlier about passing information out of a sub vi, and was helped out. The problem is that I don't understand what is happening as I can not reproduce the results. I am now trying to take results of a comparison (true-false) and pass that back out of my sub vi. I tried a property node and to connect a refnum control to it in the sub vi. Then I tried to connect an indicator to its terminal in the main vi, but was unsuccessful can someone tell me how and why, step by step, to pass this information out.

Step by step:
1. On your main vi Front Panel, create your boolean indicator.
2. On the block diagram, right click the new boolean indicator and select Create - Reference.
3. On sub-vi front panel, create boolean indicator (or use one that is already created).
4. On sub-vi front panel, create a reference (Controls Palette - Refnum - Control Refnum).
5. Right click on the newly created Refnum and select Select Vi Server Class - Generic - GObject - Control - Boolean. The refnum label changes to BoolRefnum.
6. On sub-vi block diagram, create Property Node (Functions - Application Control - Property Node). Find the BoolRefnum and move it close to the new Property Node.
7. Wire the BoolRefnum to the reference input of the property node.
8.
Right click on the property node and select Change to All Write.
9. Move mouse to point to Visible inside property node box, left click and select Value.
10. Wire the boolean indicator from step 3 to the Value input of the property node.
11. On sub-vi front panel, right click on icon and select Show Connector.
12. Click on empty connector spot then click on the new BoolRefnum. Save your sub-vi.
13. On main vi block diagram, connect refernece created in step 2 to the new connector terminal of sub-vi.
14. Save and run.
Here are the modified vi's.

Using the Formula Node for PDA

I get a compile error when I use C code inside the formula node. Is it possible to use C Code inside the formula node for PDA applications? Do I have to include any file while building the executable for the PDA

Ok, I was able to successfully build an executable file without error. I attached the screen shots of your program in execution. Does this look like the desired result?
I'm confused as to why I can build and run the program on my machine. I have LabVIEW 7.0 and Windows XP. What version of Windows and LabVIEW are you using? Also, are you getting the error window when you try to build an executable or when you attempt to run the VIs within LabVIEW?
