How to get a reference to a Project Library?

Hello DSC 8 users,
In my project I have couple project libraries ( *.lvlib) defined, containing only shared variables. I want to logg those variables to Citadel, but I need to programmatically set datalogging properties for each library, like Database Computer, Database Name and path etc.
My problem is that I can not get the reference to a particular library, because ther is no VI inside. Is there any way to get the reference to a library based on Shared Variable name that is inside the Library?
I tried different approaches, the closest that I came is to store a VI inside the Library, get the reference to this VI and from tis reference I can get to Library property that I need.
But in case there is no VI inside, I can't do it. I'm sure there is a solution to this. Can somebody please help?
Thank you,
ROMP

Hi,
i might be overlooking something here, but i can only seem to open a vi refenece and not a "library" reference. when i use the "open VI reference.vi" from the programming->application controll menu it throws an error at me.
currently i have worked round this by using a member of the lib to then get its "library" property and do what i want from there. However this isnt the best way for me as i want to be able to start with just a .lvlib file path and then document information about this library.
Any help on how to open a ref to a .lvlib dirrectly would be fantastic.

How to get the reference of the cell id in validate method in adf

Hi All,
I am using Jdeveloper 11.1.1.2 and i am using custom validator where i have registered the validator in facesconfig.xml.I need to know how can i get the ID of the inputtext box which is present in the hierarchy as Panel Header->Table->column->textbox :-
Below is my custom validator class source , please tell me how to get the reference of the textbox which is present in such hierarchy.:-
package validator;
import java.io.Serializable;
import java.util.Date;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.Validator;

public void validate(FacesContext facesContext, UIComponent uIComponent,
Object object) throws ValidatorException {
System.out.println("*************");
System.out.println((String)object);
//get component id by get("AttributeName");
String conversionComponentId = (String)uIComponent.getAttributes().get("UncommittedOrder_PH:t7:it14");
System.out.println("conversionComponentId=" + conversionComponentId);
RichInputText conversionComponent = (RichInputText)uIComponent.findComponent(conversionComponentId);
Integer conversion = (Integer)conversionComponent.getValue();
Integer quantityInBags = (Integer)object;
//get labels from the two inputDate component.
String conversionLabel = conversionComponent.getLabel();
String quantityInBagsLabel = ((RichInputText)uIComponent).getLabel();
Integer remainder = (quantityInBags % conversion);
//throw error if valiation fails
if (remainder > 0) {
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR,
"The " + quantityInBagsLabel + " should be in multiples of" + conversion +".",
null));
Thanks,
Plese reply!!!

You can go with standard JMX API using WLST

How to get File Reference of a properties file from EJB

Hi,
I am using Sun App server 7 with Oracle 9i. I am keeping all my SQL statements in a properties file from which I am loading it while making a database operation from Stateless beans. My problem is I am not able to get the reference of the properties file. Here is the code through which I am getting the SQL statements loaded to a cache.
String sqlFileName = "SQL.properties";
sqlCache.load(new FileInputStream(sqlFileName));
From the cache I am sending the SQL statement depending on the key value. But the problem is I have to keep the SQL.properties file on the App Server config directory of the instance where the server.xml file resides. Otherwise it is not able to find the properties file. But I don't want to put the properties file on the config directory of the server instance. Please help how to get the properties file from the packakge. My file is residing inside a package com.company.sql . Botht the properties file and the class accessing the file are residing in the same package. Please help how to get the reference of the file with out putting the file in the config directory.
Thanks

Just wanted to warn you of the hazards if you read a file from EJB
So please make sure that these hazards will not affect your application. However the solution suggested to use getResourceStream() concurs with ejbSpec
This snippet is from suns blueprint on ejb
Why can't EJBs read and write files and directories in the filesystem? And why can't they access file descriptors?
Enterprise beans aren't allowed to access files primarily because files are not transactional resources. Allowing EJBs to access files or directories in the filesystem, or to use file descriptors, would compromise component distributability, and would be a security hazard.
Another reason is deployability. The EJB container can choose to place an enterprise bean in any JVM, on any machine in a cluster. Yet the contents of a filesystem are not part of a deployment, and are therefore outside of the EJB container's control. File systems, directories, files, and especially file descriptors tend to be machine-local resources. If an enterprise bean running in a JVM on a particular machine is using or holding an open file descriptor to a file in the filesystem, that enterprise bean cannot easily be moved from one JVM or machine to another, without losing its reference to the file.
Furthermore, giving EJBs access to the filesystem is a security hazard, since the enterprise bean could potentially read and broadcast the contents of sensitive files, or even upload and overwrite the JVM runtime binary for malicious purposes.
Files are not an appropriate mechanism for storing business data for use by components, because they tend to be unstructured, are not under the control of the server environment, and typically don't provide distributed transactional access or fine-grained locking. Business data is better managed using a persistence interface such as JDBC, whose implementations usually provide these benefits. Read-only data can, however, be stored in files in a deployment JAR, and accessed with the getResource() or getResourceAsStream() methods of java.lang.Class.
Hope this info helps!

How to get a reference to the owner of a class instance?

Within a method of a class, how can I get a reference to the
object containing the class instance?
To be clear: I have class B that contains a method, say
"myfunc()". Class A (say, the application itself or a custom
component) instantiates a new instance of Class B : myclassB=new
ClassB()
Now, from within myfunc() can I get a reference to Class A?
The simplest way here is to pass a "this" reference when
calling myfunc(), i.e. "myclassB.myfunc(this)" but I would prefer
not to have to remember to always use 'this'.

Are these objects within each other. Does classA own classB?
If that is the case, then Greg is correct and it should be
available in parentDocument.
In projects in the past we have created a central
refObjectLocator object that is available to all objects.
Mostly we use events to communicate between objects. Dispatch
an event and let whoever listen for it.
Here is a copy of our reflocator if you are interested.
package com.goconfigure.model {
import mx.collections.ArrayCollection;
import com.adobe.cairngorm.model.ModelLocator;
import com.goconfigure.util.HashMap;
[Bindable]
public class RefObjectLocator implements ModelLocator {
// this instance stores a static reference to itself
private static var refObject : RefObjectLocator;
public var refObjectHM : HashMap = new HashMap();
// singleton: constructor only allows one model locator
public function AppLocator() : void {
if ( RefObjectLocator.refObject != null )
throw new Error( "Only one RefObjectLocator instance should
be instantiated" );
// singleton: always returns the one existing static
instance to itself
public static function getInstance() : RefObjectLocator {
if ( refObject == null )
refObject = new RefObjectLocator();
return refObject;
public function addRefObject( pRefObject : Object, pName :
String ) : void {
refObjectHM.put(pName,pRefObject);
public function getRefObject( pName : String ) : Object {
return refObjectHM.getValue(pName);
public function removeRefObject( pName : String ) : void {
refObjectHM.remove(pName);
public function clearRefObject() : void {
refObjectHM.clear();

How to get the reference of the component JSF by the faces context

I have :
<h:commandLink id="toto" action="#{controller.test}" >
I want to get the reference of this commandLink component in function test of "controller ", for instance , to get the "id" attribute of it, so how to do it? by facescontext??????
Thanks a lot.

hi again:
to precise my question, i know that attribute "actionListener " of the component can let the controller.test know the reference of the component ,but if i want to know when the getters are called for example <h:outputText value="#{controller.myValue}"> it calles the controller.getMyValue() , so in the getMyValue, how to know which component calls him?
Thanks a lot...

How to get audio files to follow project tempo??

Im tryin to figure out how to get my mp3 audio files to follow project tempo and transition up or down to any specific tempo.. is there any way of doin it? thanks

Hi,
Yes, you need to convert them into Apple Loops. First, you have to convert them to either AIFF or WAV format (or use the original WAV). You can do that in the Audio Bin. Drag the converted file onto an audio track.
In the Arrangement window select the newly created region of the audio file. In the Arrangement window menu under 'Audio', choose >Open in Apple Loops Utility...
Next, take look at p 618 in the LP8 Manual 'Creating Apple Loops in the Apple Loops Utility'. That should/may get you there.

How to get a reference for custom controller

Hi All,
I am working with the custom controller but i dont know how to call the functionality of custom controller into a view controller.For accessing component controller functionality we have a attribute wd_comp_controller in view controller.Like this how to get a refernce for the custom controller.
Thanks in Advance.

hi,
Lets say view1 has the event ONACTIONNAVIGATE and you want to call a method 'start_navigation' in the custom controller named 'navigation'.
Use the following code.
METHOD onactionnavigate .
DATA lo_navigation_controller TYPE REF TO ig_navigation.
lo_navigation_controller = wd_this->get_navigation_ctr( ).
CASE navigation_type.
WHEN 'BACKWARD'.
lo_navigation_controller->start_navigation( if_fitv_fpm_api=>gc_navigate_backward ).
WHEN 'FORWARD'.
lo_navigation_controller->start_navigation( if_fitv_fpm_api=>gc_navigate_forward ).
ENDCASE.
ENDMETHOD.

Open VI Reference for a Project Library VI

Hi,
my code calls some subVIs by reference by using "Open VI Reference" and "Call by Reference" VIs. Now, "Open VI Reference" expects a path to the VI:
When the SubVIs sit in the same folder as the calling VI, it is easy to simply supply the name of the SubVI. However, I would like to call a SubVI that is part of a project library sitting somewhere else on the disk. I could give the relative path, but this make the code pretty inflexible and if the relative path changes all the paths would need to be ammended. Ideally, I want to utilize the fact that I am using a project library. The help for Open VI Reference states that
vi path accepts a string containing the name of the VI that you want to reference or a path to the VI that you want to reference. If you wire a name string, the string must match the full delimited name of a VI in memory on that target. If you wire a path, LabVIEW searches for a VI in memory that you previously loaded from that path on the same target.
I thought that the underlined path was my ticket and tried something like this:
but this did not work and I got
"Error 1004 occurred at Open VI Reference in MainVI.vi:
Possible reason(s):
LabVIEW: The VI is not in memory.
To load a VI into memory with the Open VI Reference function, a path must be wired for the VI Path input."
Wiring a path is not desirable as per reasoning above. Is there a way around the issue?
Thanks in advance!
Solved!

That should work, but you have to pay attention to something that's stated both in the help and in the error - if you use a string, the only way for LV to know what to access is if that something is already "in memory" (sometimes also referred to as "being loaded"). In the case of standard libraries, that means the VI itself or one of its callers has to be loaded. In the case of classes and XControls, loading the library (as in having it in an open project) should be enough to also load all of its members.
Hm, thanks, I am not advanced enough to know about classes and XControls, but I will check it out. My VIs are part of a library but obviously don't get loaded because, as you said, all their calls are dynamic.

What I usually do is use a static reference to a VI to get its name, because that ensures that it will be statically linked, included in executables, etc. That might not work for you if you want dynamic loading and then you will need to use some other means.
Hm, this actually gives me an idea! I could add an enable input to all these dynamically called VIs so that the logic runs only when enable is ON; otherwise the VI is called but does nothing. Then I call the VI first statically with enable=OFF just to load it in memory and then proceed with my dynamic call. A little ad-hoc, but should work and serve my purposes, I think.
Thanks!!

How to relink clips THROUGH the new Project Library??

I updated everything to FCPX 10.1.1.
Some clips became unlinked. I go to link them ... and am stopped dead by the NEW Library Icon (with all it's internal folders no longer seemingly accessible). I know the file is in there - if I do a search in Finder for the missing media, it takes me right to where it is.
When I do a relink, stopped dead in my tracks by the new format.
How do I access the folders hidden in the new Project Library to relink my clips with their original media?

you miss the concept of Libs:
Libraries are no 'real world' folders, just a 'register' where is what .. in best-of-all-worlds, all data (audio, video, stills, projects ...) are on the same drive - but the concept of Libs allows data spread all across your network But handled as 'one', e.g to finally-save Projects, outsource old data etc ...
A Lib acts like a (super-)folder, but isn't. Simple example: a 10GB lib could fit on a 2GB drive! .. if data is spread on some other drives. But Finder says 'here', due to use of hard- or sym-links. ....
... I read in my searches that one doesn't have to have one's media stored in the Library, but I haven't found a protocol yet for saving media elsewhere.
It's always in some LIb, but not physically... s.above ...
.. One thing I can't figure out: Folders. I love folders. I use them all the time to organize.
obsolete,
get familiar with the concept of tags/keywords/smartlists.
example:
a clip is tagged x-mas, grandma, 2002, funny scene .. one clip, one storage location, many ways to find it.
now, your old drawer/folder system: the scene with grandma wearing a funny hat ... do I have to dig in folder 'videos2002' or 'videos2003'? sub-folder xmas or birthday? or is it n my 'out-takes drive'.. but under what name? your one clip can only be in one drawer... but should be found under several keywords... sooo?
Folders = old school
tags = much more convenient.
(plus: you can use tags very similiar as your old folders... but a computer is much faster in dig'n-search than you, manually
concerning re-linking:
I once had the effect, a 'lost' drive had to be re-mounted:
the red-icon-of-terror (cam missing), relink doesn't came up with a suggestion; clicked on import from camera, clicked to my cam-archive on some drive - and WHILE doing so FCPX instantly found the old connection (no re-import nor re-linking neccessary)..
That drive was unintended un-plugged while using FCPX ..... never happened again.

How to move all thumbnail clips into project library for editing?

Hi there ...
I haven't used imovie 08 for quite a while ... and I've forgotten how to do a major step .. which is leading to a lot of frustration. I need to drag all my thumbnails into the project library and have them available for editing. ANy way I try it now .... it seems to create one big clip in the project library .. so when I want to add a title or something ... when I drag it over to the clip ... it selects to add to the whole movie. Somehow I need to retain the individual thumbnails or clips ... so when I try to add effects it is just added to one clip ... not all of them ...
I had this problem before and I can't remember how I moved all the separate clips from the event library to the project library and had them retain their individual clip format available for edit...
CAn anyone help me .... thanks ....

Hi,
This is a shot in the dark but: if it is anything like 09 there is a little slider in the bottom right hand corner of the project window which, if it is all the way to the right will only give you the whole movie.
Pull it to the left to give you different thumbnail settings.
Hope this works.

How to get the colums from a project view

Greetings,
I have a PjView-object from type Microsoft.Office.Interop.MSProject.View
and I can output the name of the view (MsgBox(PjView.Name.ToString)
So far so good.
But now I have two questions:
1. How do I access the columns that are included in this view?
2. If I have a column, how can I read the Title property (In Project: Field Settings -> Title)
Thank you!
Michael

This code will get the fields that exist on the Gantt Chart view in the current project:
Public Sub GetCurrentViews()
Dim vw As View
Dim vw_sng As ViewSingle
Dim vw_com As ViewCombination
Dim tbl As Table
Dim fld As TableField
Set vw = ActiveProject.Views("Gantt Chart")
If vw.Single Then
Set vw_sng = vw
Else
Set vw_com = vw
Set vw_sng = vw_com.TopView
End If
Set tbl = vw_sng.Table
Debug.Print tbl.Name
'step through each column on each table
For Each fld In tbl.TableFields
'check that it isn't the "Insert column" marker
If fld.Field <> -1 Then
'if it is an actual field, output field title
Debug.Print " " & fld.Title
Debug.Print " " & fld.Field & " - " & Application.FieldConstantToFieldName(fld.Field)
End If
Next fld
End Sub
Hope that helps,

How to get the reference of the View controller in from Custome controller

Hi friends,
From one of the Custome controllers in my Component,I am raising a popup based on conditions.
I want to subscribe to popup buttons.
Following is the code that I have written.
IF LT_RECEIPTS_T[] IS not INITIAL.
    data lo_window_manager type ref to if_wd_window_manager.
    data lo_api_component type ref to if_wd_component.
    data lo_window         type ref to if_wd_window.
*BREAK-POINT.
    lo_api_component = wd_comp_controller->wd_get_api( ).
    lo_window_manager = lo_api_component->get_window_manager( ).
    lo_window         = lo_window_manager->create_window(
                       window_name            = 'W_PERSONALCARDPOPUP'
                       message_display_mode   = if_wd_window=>co_msg_display_mode_selected
                       button_kind            = if_wd_window=>co_buttons_okcancel
                       message_type           = if_wd_window=>co_msg_type_none ).
    lo_window->open( ).
    DATA: view_controller TYPE REF TO if_wd_view_controller.
    view_controller = wd_this->wd_get_api( ).
    CALL METHOD lo_window->subscribe_to_button_event
      EXPORTING
        button      = if_wd_window=>co_button_ok
        action_name = 'OK'
        action_view = view_controller.
as I am In Custome controller,wd_get_api is returing of type if_wd_controller,but the subscribe_to_button_event
requires action_view of data type if_wd_view_controller.
but,my problem is that I can keep the view only Custome controller.
when I pass the 'VIEW_CONTROLLER' variable to method subscribe_to_button_event,I am getting the error as type missmatch.
Please suggest how I can rectify this error.
Regards,
Xavier.P

Hi Xavier,
You try this
1. Define an attribute in your custom controller to hold your popup window reference for e.g lr_popup of type if_wd_window
2. Store the popup window reference in lr_popup when calling your popup
lo_api_component = wd_comp_controller->wd_get_api( ).
          lo_window_manager = lo_api_component->get_window_manager( ).
          wd_this->lr_popup = lo_window_manager->create_window(
                          window_name = 'W_PERSONALCARDPOPUP'
                          message_display_mode = if_wd_window=>co_msg_display_mode_selected
                          button_kind = if_wd_window=>co_buttons_okcancel
                          message_type = if_wd_window=>co_msg_type_none ).
         wd_this->lr_popup->open( ).
3. Define the custom controller usage in the properties of your popup view
4. In WDDOINIT of your popup view write the following
DATA lr_custom_controller TYPE REF TO ig_<Custom Controller>.
        lr_custom_controller = wd_this->get_<Custom Controller>_ctr( );
        lr_custom_controller->lr_popup->subscribe_to_button_event(
     button = if_wd_window=>co_button_ok
     action_name = 'OK'
     action_view = wd_this->wd_get_api( ) ).
5. Define the event handler for OK in your popup view
Best Regards,
