Event when network changes

Hello all,
I am trying to figure how to use an activex callback when the computers(windows 7) network connection changes.
I am able to access and use properties of the NETWORKLIST.INetworkListManager class but I am not able to get the Reg Event Callback to work for NETWORKLIST.INetworkListManager.NetworkConnectivityChanged.
Does anyone have experience with this class or more ActiveX knowledge to get this working?
Perhaps there is another more commonly used method to see network changes without polling?
I hope I have provided enough details to get some help. Thank you for your time.

I cannot get this working in LabVIEW 2013 32-bit.
Not sure why.
I am able to get the callback to work in C# Express 2010.

APP-FND-01926 The Custom Event WHEN-LOGON-CHANGED...

Hi,
After compiling and placing a 'custom' CUSTOM.pll (and plx) file on the server, when logging into Applications receiving ERROR:
APP-FND-01926 The custom event WHEN-LOGON-CHANGED raising unhandled exception: User Defined exception.
This is for R12.1.3
The code was moved to the original base version of the R12 CUSTOM.pll file...
I read many other Notes on this error, but most refer to an error related to a Program Unit Not found and requiring a regeneration of the JAR files.
Would this be the same situation?
When we place the original back in place the forms login works.
Any ideas?
Thanks,
Lamonte

check ur CLASSPATH environment variable ur Custom.plx library should visible on runtime to Classpath variable.

Dev2k and event when tabpage changed ?

Hi !
Does Dev2k 5.0 generate an event when you press or change a
tabpage? I haven't succeded in finding one yet, but perhaps
someone knows about it or know of a workaround ?
Also there is a trigger called ON-DISPATCH-EVENT !! Does anyone
know what you can do with this ? or what it does ?
Thanks,
Kenneth ([email protected])

When you click on a tab in forms 5 and greater, it first
when-tab-page-changed. Note that this trigger only first when a
users explicitly clickes on a tab. If the application allows you
to navigate to an item on a different tab page, the trigger does
not fire, but the tabs do change to reflect the current tab.
Also, there are two system variable that are helpful; they are
:system.tab_new_page and :system.tab_previous_page. For some
reason, the help system only includes references to the tab
trigger and system tab variables on the FIND tab of the help
search. The INDEX tab page of help does not list them.
Good luck.

How to Fire ondisconnect event when network disconnect suddenly

Hello Friends
                      can any body tell me how to clear the client entry from Adobe flash Media server 3.5. when net disconnect.
i was expecting that on netdisconnect from the client side end(which is connected to FMS) its onDisconnect event fire similarly as it fire for browser close.But when internet disconnect ondisconnect event not fires at FMS side is there any way to overcome this or any other event fire at that stage?
if it is possible to get any event on network disconnection at client sidetahn i can solve the issue.
Thanks and Regards
   Vineet osho

You must be getting the "NetConnection.Connect.Closed" as info.code in the onStatus for the NetConnection.
See http://livedocs.adobe.com/fms/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDoc s_Parts&file=00000742.html
nc = new NetConnection();
nc.onStatus = function(info){
    if (info.code == "NetConnection.Connect.Closed")
        // Netconnection has closed.

Generate event when stack changed

I have a task develop a class Stack that generate event when you add new element ? Develop a class Stack is not a problem, what means event that apears when a new element is added ?[

That about awt / swing ..or I can to apply listeners
to My Stack ?Sorry, I thought there were also non-GUI examples there. Apparently not.
It's probably the intention to implement the observer pattern into your code.
Here's a small demo of how this can be done:import java.util.List;
import java.util.ArrayList;
class Main {
    public static void main(String[] args) {
        MagazinePublisher publisher = new MagazinePublisher();
        Subscriber carl = new Subscriber("Carl");
        Subscriber pete = new Subscriber("Pete");
        Subscriber zeke = new Subscriber("Zeke");
        publisher.registerObservers(carl);
        publisher.registerObservers(pete);
        // whenever the state of the 'publisher' changes, it's
        // subscribers should be notified
        publisher.notifyObservers();
        publisher.registerObservers(zeke);
        publisher.notifyObservers();
        publisher.removeObservers(pete);
        publisher.removeObservers(carl);
        publisher.notifyObservers();
interface MyObserver {
    void update(int edition);
interface MySubject {
    void registerObservers(MyObserver mo);
    void removeObservers(MyObserver mo);
    void notifyObservers();
class MagazinePublisher implements MySubject {
    List<MyObserver> observers;
    int edition;
    public MagazinePublisher() {
        observers = new ArrayList<MyObserver>();
        edition = 1;
    public void notifyObservers() {
        for(MyObserver mo : observers) {
            mo.update(edition);
        edition++;
    public void registerObservers(MyObserver mo) {
        observers.add(mo);
    public void removeObservers(MyObserver mo) {
        observers.remove(mo);
class Subscriber implements MyObserver {
    String name;
    public Subscriber(String n) {
        name = n;
    public boolean equals(Object o) {
        return this.name.equals(((Subscriber)o).name);
    public void update(int e) {
        System.out.println(name+" recieved a copy of the "+e+" edition!");
    // hashCode() and other methods ...
}Details about this design pattern:

Possible bug - Missing click event when handling change event

Using Flex 4.5 SDK, I have a spark ComboBox and a Button next to it for applying a filter according to ComboBox selection.
I listen to both the ComboBox's change event & the Button's click event (for different functions).
When I manually delete the ComboBox text value from its TextInput (i.e. changing selected index to -1) and immediately click on the Button,
the click event-handler function is not being called and only the ComboBox's change event-handler function is executed.
(Selecting a value from the ComboBox's list and clicking on the button triggers both methods on the right order.)
There's also a state definition for the module, but it isn't being changed during these operations...
Is this a bug or a correct behavior? Am I missing something here?
Any workaround suggestions?
(I thought of listening also to mouse-down or mouse-up on the button instead, but haven't tried it yet...)
*** UPDATE ***
When using the Button's mouseDown event the behavior is as expected, so there's a simple workaround.
However, it seems to me like there's a bug with the Button's click event listener or something...
*** UPDATE #2 ***
I created a test application for that and couldn't reproduce the problem.
Then I figured out the problem and solved it.
It's a bit emmbarrasing, but I actually disabled the button (enabled=false) as in a child method of the change handling code...
(If there is no value, don't allow applying the filter - It makes sense! )
Anyway... No issue after all.
However, I choose to leave this post (and not delete it) as an example of identifying and resolving a strange behavior in a complex application.

There's no need.
Please read the section UPDATE #2.

What is the proper event when i change an edit text

Hi Dear;
which event is when i an edit text value changes ?
regards

If you want to catch changes in exittext, store his value to global variable or somewhere to other exittext (invisible) and play with event
pval.EventType = SAPbouiCOM.BoEventTypes.et_KEY_DOWN
and compare the values in edittext and invisible edittext. If the values are different, the edittext value changes.

Event when Sequence changes

Hi!
In my GUI application I need to get the name of 'Sequence' when 'Sequence' of an Execution changes. Is there any event to get this change. Please help
Thanks

tsgy,
I couldn't find an event that would notify you of when the sequence of an execution changes, but you don't say why you are trying to use this information.
If you just want the name of the sequence for display reasons, then you can use any of the TestStand UI Controls, such as the Label. Then you can use ExecutionViewManager.ConnectCaption with the Caption Source of CaptionSource_CurrentSequence

Catch events when documents change

Hi. We would like to do realtime indexing of content in our km engine. Is there a way to create a listener which is triggered anytime a document changes, so that we can inform our "TREX" (or a 3rd party search engine)?
Next step would be to also catch an event everytime permissions for a document change.
I would appreciate, if someone could elaborate on the possibilities.

Hi Sebastian,
yes, you can implement an IEventReceiver an listen to certain events:
public class MyEventReceiver implements IResourceEventReceiver {
    public MyEventReceiver() {
     IResourceEventBroker broker = resource.getRepositoryManager().getEventBroker();
        broker.register(this, IResourceEvent.RENAME_EVENT, IEventBroker.PRIO_MIN, true);
    public void received(IEvent event) {
     if( event instanceof IResourceEvent ) {
      IResourceEvent resourceEvent = (IResourceEvent)event;
      IResource resource = resourceEvent.getResource();

Is it possible to generate a user event when shared variable value change on RT target?

Hi,
    I wonder if it is possible to generate a user event when a network published shared variable value change?
    Thanks a lot!
    Regards,
    Tom

Tom,
I understand not wanting to waster resources on polling but I am not aware that LabVIEW can automatically generate an event on a SV change.
Maybe a better solution...
You could implement lower level TCP communication (i.e. have a look at STM - simple messaging protocol) for passing data betweeen RT and PC (instead of using a SV). You could send a generic command (boolean trigger maybe?) from your RT system when the value of whatever it is the SV is storing has changed. You can avoid polling on the non-RT system this way.

Can I switch calendars (Ex. "night shift" to "day shift" cal) with a repeating event, but ONLY for that one event?? It asks "for all events or only this event" if i change the time. But it changes ALL events when i try and switch calendars. Any help??

I have 2 calendars set up for my work schedule, a "night shift" and "day shift" calendar. I've set up repeating events fro Fri/Sat/Sun 3-11pm "night shifts" and Mon/Tues 7am-3pm "day shifts". But lets say for example that I swap shifts and instead of working nights on Saturday like I normally would, I am now working days. I want to change that in my calendar. When I go to change the event, if i change the TIME it asks if i want to change all event or ONLY this event. no problem....just this single event. but when i go to change the event from the "night shift" calendar to the "day shift" calendar, it changes ALL the repeating events, and not just that one single event. can anyone help with this??? am i doing something wrong? is there a way to do this or not with the new iCal program??? i used to do this and never had any problems. Thank you!

You need to follow iPhoto terms since we only know what you tell us
what are you calling folders - in iPhoto folders can not hold photos - albums hold photos and folders hold albums or other folders
The basic default view of photo is by event (iPhoto '08 and later)
Exactly what you you trying to do?
