How to create a strict property node!

I have been searching a way to create a strict property note for a whole day, and yet still can not get the answer.
I have download a Vi from the Ni website, but my lab computer can not open it, So i open it with my lab-top, and trying to duplicate it in the lab computer.
After i have done it, when i try to run the VI, an error come out say that
"Boolean ''stop": Boolean latch action is incompatible with local variables."
Then i check for the difference with the original one, the only difference is that the property node of the original one is a strict property type, and the one. when i am trying to do the same thing for the duplicated one, i can not find the way.
So, i try to search for the answer, something like this come out
"Conversely, a strictly typed refnum does contain the data type for the object that it points to. You can change between weak and strict refnums by right clicking on the refnum (or its terminal in the block diagram) and selecting "Include Data Type" for strict and deselecting it for a weak typed refnum. "
but when i right click all the icons show in the block diagram, i didn't see any "include data type come out".
attached is the picture of the diagram.
Why is that when i try to create the same property: value as in the picture using the lab computer, and the color of the "value" will appears to be purple when what i expected should be green for the boolean value.
Solved!

The error you are getting is telling you that the boolean control is set to Latch Action. You need to change it to a Switch Action.
To do this, go to the boolean control on your Front Panel, right click it with the mouse and select a one of the top three Switching Action from the Mechanical Action list of six action types.
The reason for this is that a Latching switch is cleared when read by the terminal on a block diagram, but having used Local Variables in your code you are now reading the control from more than one place. Therefore the boolean needs to be set to Switch, whereby it will retain it's setting after being read to ensure that all Local Variables will see the correct value.

How to create a specific property node w/ VI script

I am writing a VI script to work with some multi column listboxes. I need it to create a property node that gets a reference to the ItemNames field. I see that I can create a property node via the invoke node method Create.Property Node, but how to get the ItemNames field specifically I so far can't figure out. Can anyone help?
To be clear, I am writing code that looks like this:
...and when I run the script, I want it to produce this:
Right now it produces the MCL as expected, via the New VI Object node...but I don't know how to get the ItemNames created automatcially. I thought it might be in the PropItems array but so far no luck.
thank you

The output of "PropItems[]" will be a one element array. Index that element and wire the reference to an invoke node. Select the method "SetProperty".

How can I make a "property node" for a VI?

Hello!
If I add a boolean button on the FP then I am able to make a property node for that button in the Block Diagram. But how can I make a property node for a VI? I have several VI:s an that together is one program. What I need to do is to verify what kind of VI some of my VI:s is. I need to verify if it is .exe or .vi-file, and if it is .exe then I want to disable run, abort, run continuously bottons otherwise not. I have hard that this is possible to do programmaticaly but I can´t figure out how. I am aware that I could do that manually in the File->vi properties->customize->windows appearance but theese choises makes it last forever.
I want to be able to stop and run and everything if it is a .vi file, but if it is .exe-file then all those buttons should be disabled.
Anyone have an example on this?
In an other message at this Forum I read "You can use the `Front Panel Window. Allow Runtime PopUp`" property to disable run-time shortcuts menues programmaticaly, but still I dont know how to create this property node.
/Amir

You really shouldn't open a new thread. If you don't understand something, ask and we will explain it.
Like I said in the other thread, you can check if you are running in LV or an EXE by using the Application>>Kind property. To get it, place a property node (from the Application Control palette) on the diagram, click it and find the property.
To set the properties for the VI, place another property node, right click it and select Select Class>>VI Server>>VI. You should have the properties you want under Front Panel Window.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf). I believe chapter 17 of the user manual explains about programmatic control of VIs.

How to create a dynamic property in JavaFX ?
ObservableMap, ObservableMapValue, MapPropertyBase, MapProperty
Which one should I use. Can you give an example?

I'm not sure what you mean by "dynamic property"; can you be more explicit?
Your code creates two properties that can be read, written, and observed for changes, though it's probably better to use the standard naming scheme for the methods (e.g they should be getName(), setName(...) and nameProperty()).
An ObservableMap is an extension of the java.util.Map interface that can be observed; i.e. you can register a listener that will be notified if a key-value pair is added or removed from the map.
ObservableMapValue is an interface that defines an observable reference to an ObservableMap; i.e. it has a get() method returning an ObservableMap and a set(...) method taking an ObservableMap. You can register a ChangeListener which is notified when the set(...) method is called. It additionally functions as an ObservableMap, so you can also register listeners that get notified when key-value pairs are added or removed from the underlying observable map.
MapProperty and MapPropertyBase are effectively partial implementations of ObservableMapValue. SimpleMapProperty is a full implementation.
If you just need a single ObservableMap (i.e. not an observable reference to one), then the FXCollections.observableHashMap() factory method will provide one.

How to create a blinking property on the XY graph?

Hello.
I am monitoring two lines that has a chance to collide from each other. The lines are represented through the XY Graph.
The user would like to see a "blinking" rectangle or square shape (depending on the lenght of the line) enclosing the line,
if collision is imminent. But if there is no collision, the rectangle or square shape will not be visible on the XY graph.
This is for the operators visual to check where is the collision might happen.
I attached a simple illustration of what i wanted to do.
1. How can I create the rectngle or suare shape figure if i am only given coordinates at the end points of the line?
2. How can i create the blinking property in the XY graph?
I would greatly appreciate for any help if above is possible.
Thanks a lot.

Based on what you're saying it sounds like you're already determining if you have a collision situation and are turning on the LED. To draw the rectangle you can juse use the drawing VIs to draw on on the graph's drawing layers. You have three available to you: foreground, background, and middle. Examples ship with LabVIEW to show you how to use them. As for the blinking part you would need to handle this yourself. I would do it by having a separate loop that does the drawing. If the blinking condition is set, then you just need to toggle the box on and off (by clearing the picture to turn if off, and then drawing the rectangle to turn it on).

How to create a strictly typed refnum control using LabVIEW scripting

I wish to use LabVIEW scripting to create a strictly-typed refnum control that is bound to my custom control (a type-defined cluster), but I'm unfamiliar with scripting and can't see how to do it.
If I create a New VI Object, using Control Refnum as the Style, how do I provide my custom control to the VI Object Class terminal? When I try using a reference to my custom control.ctl file (using Open VI reference) I get an error: "Error 1057 occurred... Type mismatch: Object cannot be cast to the specified type."
Or, if I create a new Control Refnum as above, using a standard Cluster as the VI Object Class, how do I then convert this refnum control to a strictly typed refnum that is bound to my custom cluster control type?
Thanks in advance for any advice,

Here we go...
You have to create a new Control VI and then specify the VI Type as Typedef.

How to create and use a node globally as well as internal table

HI,
Kindly let me know how can I create a node & internal table globally and which I can use them in various methods in view and controller as well, if u can provide an example it could be very help full.
my requirment is uploading a multiple files in wdp ABAP for this I just followd the link below
http://wiki.sdn.sap.com/wiki/display/WDABAP/UploadandDownloadfilesinWebdynproABAP
which for single upload and for making this for multiple upload I need a node could be usefull globally or a IT please check my code below
DATA lo_nd_n_upload TYPE REF TO if_wd_context_node.
    DATA lo_el_n_upload TYPE REF TO if_wd_context_element.
    DATA ls_n_upload TYPE wd_this->element_n_upload.
    DATA lo_nd_n_file_download TYPE REF TO if_wd_context_node.
    DATA lt_n_file_download TYPE wd_this->elements_n_file_download.
    data ls_file_upload TYPE ZFILE_UPLOAD1.
   ZFILE_UPLOAD_1 = wd_componentcontroller->Elements_ZFILE_UPLOAD_1.
     t_file_upload = ig_componentcontroller->ITAB1.
   t_file_upload = wd_this->zfile_upload1.
   navigate from <CONTEXT> to <N_FILE_DOWNLOAD> via lead selection
     lo_nd_n_file_download = wd_context->get_child_node( name = wd_this->wdctx_n_file_download ).
navigate from <CONTEXT> to <N_UPLOAD> via lead selection
    lo_nd_n_upload = wd_context->get_child_node( name = wd_this->wdctx_n_upload ).
get element via lead selection
    lo_el_n_upload = lo_nd_n_upload->get_element( ).
@TODO handle not set lead selection
    IF lo_el_n_upload IS not INITIAL.
get all declared attributes
    lo_el_n_upload->get_static_attributes(
      IMPORTING
        static_attributes = ls_n_upload ).
ls_n_upload will contain the File name file type and file contents *
   ls_n_upload-file_size = xstrlen( ls_n_upload-file_content ).
   ls_file_upload-FILE_NAME = ls_n_upload-FILE_NAME.
   ls_file_upload-FILE_TYPE = ls_n_upload-FILE_TYPE.
   ls_file_upload-FILE_SIZE = ls_n_upload-FILE_SIZE.
   ls_file_upload-FILE_CONTENTS = ls_n_upload-FILE_CONTENT.
   append ls_file_upload to t_file_upload.
   clear ls_file_upload.
lo_nd_n_file_download->bind_table( new_items = t_file_upload set_initial_elements = abap_true ).
ENDIF.
so here I would like use t_file_upload(node or IT ) to use globaly which can keep the previous data and I can add the existing data and in another method I would like to submit the data in t_file_upload to table
Regards
raj

How to create a new tree node with the initial edit function

Hi all,
I would like to mimic the Windows system when the user creates a new node. The newly created node should be in the edit mode, i.e.it should
be highlighted and the cursor should be appear at the end of
the newly created node name.
I have the folloing code after I create the new node and set its selection:
TreePath selectionPath = getTree().getSelectionPath();
tree.startEditingAtPath(selectionPath);
However, this only partially does what I want, the cursor does not appear at the end of the node's name and I am not sure how to select the text name of the new node.
I hope someone can help.
Kanita

I haven't tried myself but my guess is that you need to customize your tree cell editor for putting
cursor at specific position, etc.

How to create a dynpro property on the WAS and get it in code?

Hello,
I remember that once I've read at the NWDS help that I can create dynpro properties which can be configured on the WAS's Configuration Adapter serviceand can be retreived when the dynpro application loads. I need to use it now but can't find the explanation and code example. Can someone please show me how to do it?
Roy

Hi Roy,
1. create a .properties file with the key value pair.
2. Put it in src/configurations/application/<app name>
3.
WDDeployableObjectPart App = wdThis.wdGetAPI().getComponent().getApplication().getDeployableObjectPart();
IWDConfiguration Configprop = WDConfiguration.getConfigurationByName (App,property file name );
// get the string value of the property.
String value = Configprop.getStringEntry ("<key of the property sheet>");
To chaneg the property value outside the application,
Goto configuration adapter -> WEbdynpro -> the app name. Under that you will find the property file
You can edit the file and restart the server.

On my (non-MVC) BSP page I'd like to have a tree in which each node has a checkbox that the use can select, e.g. node 1.1: X, node 1.2: space; node 1.3: X
It doesn't seem like the standard <htmlb:tree> can do this. Is there any quick way I can achieve this functionality?
Any suggestions/code samples will be appreciated.
