Changing state of led

Hi, I have a simple program here that I want the LEDs to default to OFF when the program finishes. I tried using gates to accomplish this, but because of the delays input into the gates, it would throw off all my timing functions. What can I do so that when the program finishes it will turn off the LEDs?
I'm attaching the code, I'm using 8.2 right now.
Thanks for any help.

Sorry my ignorance, but what are "gates" in this context?

Delay in changing the state of LEDs

Hi
I am using 6 LEDs in my application. I am changing the state of LED using SetCtrlVal() function.
But for 3 LED's the change happens after some delay(around 5sec delay). I don't know how to solve
this issue. Please any me on this.
Thanks and Regards
NB
Solved!

Also - just FYI - this is a known issue that has been resolved in CVI 2010. Calling SetCtrlVal should immediately update and redraw the state of the LED.

Changing states from within a component

Let's say that I have a TileList that is rendering data in a
VBox. Eventually the TileList fills up and starts scrolling. I want
to change states when clicking on item in the TileList.
I don't want to place the click-attribute in the TileList,
because it will change states when I am scrolling the list without
actually selecting anything.
I want to say click="currentState='state2'" inside the VBox,
but that does not work because state2 is at the root level, and I
don't know how to get to the root-level (in lack of a better word)
from withing the component.
This is not the proper syntax, so misunderstand me the right
way here... Is there an equivallence to
click="currentState='_root.state2'" in mxml?
Thanks for any suggestions or best practices. I want the easy
way out.
This is the general structure...
<mx:Application>
<mx:states>
<mx:State id="state1"/>
<mx:State id="state2"/>
<mx:State id="state3"/>
</mx:states>
<mx:TileList dataprovider="{...}">
<mx:itemRenderer>
<mx:component>
<mx:VBox id="ClickThisBoxToChangeStates">
<mx:Image/>
<mx:Label/>
</mx:Vbox>
</mx:component>
</mx:itemRenderer>
</mx:TileList>
</mx:Application>

Your assumption is right.
It doesn't work because there is no state2-state defined
within the mx:component.
In the documentation about changing states it says that I can
go from application level and change states within a component;
like this: click="currentState='mycomponent.anotherstate'" but not
how I can change a state at application level from within a state.
When I try, it says (at runtime) that the state is not defined.
So I don't know why <mx:VBox
click="currentState='state2'"/> doesn't work.
I apprechiate your expertese a lot.

How to change state of a constraint from DEFERABLE to IMMEDIATE?

Hi,
I am runnig 10gR2 and would like to change state of a constraint from
DEFERABLE to IMMEDIATE without recreating it.
The change is working at the session level with
SET CONSTRAINT <constraint name> IMMEDIATE;
But this is not visible for other users.
So my question is, if there is any other way to do it, so the change would be visible for every user.
Here is what I have done:
CREATE TABLE TEST_TBL
ID NUMBER
ALTER TABLE TEST_TBL ADD CONSTRAINT pk_test_tbl PRIMARY KEY(ID)
INITIALLY DEFERRED DEFERRABLE;
SQL> INSERT INTO test_tbl VALUES(1);
1 row created.
SQL> INSERT INTO test_tbl VALUES(1);
1 row created.
SQL> INSERT INTO test_tbl VALUES(1);
1 row created.
SQL> COMMIT;
COMMIT
ERROR at line 1:
ORA-02091: transaction rolled back
ORA-00001: unique constraint (TEST_SCHEMA.PK_TEST_TBL) violated
The constraint is checked only at commit,
To change this:
SQL> SET CONSTRAINT pk_test_tbl IMMEDIATE;
Constraint set.
SQL> INSERT INTO test_tbl VALUES(1);
1 row created.
SQL> INSERT INTO test_tbl VALUES(1);
INSERT INTO test_tbl VALUES(1)
ERROR at line 1:
ORA-00001: unique constraint (TEST_SCHEMA.PK_TEST_TBL) violated
But if I would connect with user B, I would be able to do multiple inserts with value 1.
Thanks

I am runnig 10gR2 and would like to change state of a constraint from
DEFERABLE to IMMEDIATE without recreating it.From Oracle Constraints:
Note: A non-deferrable constraint is generally policed by a unique index (a unique index is created
unless a suitable index already exists). A deferrable constraint must be policed by a non-unique index
(as it's possible for a point of time during a transaction for duplicate values to exist). This is why
it is not possible to alter a constraint from non-deferrable to deferrable. Doing so would require
Oracle to drop and recreate the index.
A PK enforces uniqueness procedurally without relying on a unique index. The main advantage
of a non-unique index is the constraint can be disabled and re-enabled without the index being dropped and recreated.

PSD Rollover Button with image in front stops button from changing state

I have a wide PSD button that changes state when rolled over. I would like to place a PNG image with transparency in some areas over the top of it so that the rollover button shows through the transparent areas of the PNG.
How can you get it to do the rollover effect when the user mouses over the bit of the button that the image is in front of? Is ther a way of making the PNG 'invisible' to the mouse?
I know I could redesign the button so that it includes the image but I'm trying to keep file sizes and load times to a minimum, I use this button a lot on my website with a different on each, and having that number of individual buttons would result in a bloated, slow-loading website.

Hi Abhishek
Thanks for your reply. I was able to achieve the effect I wanted by having the PNG and the PSD Button with the same link and then grouping them. This means I can mouse over the PNG and still get the PSD rollover effect, which is perfect.
However I also have another similar problem. I have some different PSD Rollover Buttons which have some text in front of them (basically it's the button label). On some of these buttons when you roll over the text it prevents the rollover state of the button, and on other buttons the rollover effect occurs as it should, and there doesn't appear to be any consistency about which does what. Grouping or ungrouping doesn't appear to make a difference. Can you help?

Changing state of application from within a custom component

Hello, I have several custom components all of which are included in the parent application.
When I try to change state from a custom component, I get an error saying "undefined state: state name". How do I change the state of the application from within a custom component ? All the states are defined in the parent application.

@linrsvp,
If you are using Flex3 try Application.application.currentState = "somestate";
If you are using Flex4 try FlexGlobas.topLevelApplication.currentState = "somestate";
Don't forget to import the corresponding namespaces for the above.
Thanks,

Change States in component from main view

The scenario like this:
The main view includes many component views. On my main view
there have a radio button to choice different role type, for
example: admin and user. For different role have different views.
But they don’t have big difference.
My question is how could I implement my component view change
states when I click button on the main view? I don’t want do
change states in main view since I need create two component views
for different roles.
Thanks.

Consider adding a second state to your application, even if
you don't put anything into it.
In each of the components that should change state when the
role is changed, add a listener on the application for the state
change event ("currentStateChange"). When this event is fired,
query the application for its current state:
var appState:String = (Application.application as
Application).currentState;
Use that to change the state of the component. Remember
you'll also need to do this when your component is first
created.

Change state option in SM51

Hello,
I would like to know if activate/deactivate option in SM51 (see below)
menu--->edit -
>change state -
>activate/deactivate
is used for activating and deactivating servers? If not what is its functionality?
mm

Hi,
There are the following application server states -
initial - The application server has logged on to the message server. When the server is in this state, it cannot be accessed.
starting - The application server starts the work process and initializes all required services. Requests cannot be processed in this phase.
active - This is the "normal" state of the application server. It receives and processes requests, and creates and sends requests to other servers.
passive - In this state, the application server can continue to process received requests or create requests itself. However, no new requests should be sent to the server. The purpose of this state is to "logically" remove from the system a server that has to be stopped during productive operation. The server finishes processing its existing requests, but does not accept any new requests and can be terminated without having to interrupt any relevant requests such as updates or batch jobs. This state can be changed to the "active" state.
shutdown - The application server is in the shutdown phase, that is, it will be terminated. This state is similar to the "passive" state, but cannot be changed to the "active" state. This state or phase ends with the termination of the server.
stop - The application server has terminated the connection to the message server and can no longer be accessed.
Use
The server functions are used to deactivate or close down SAP servers without jeopardizing the requests the server is currently processing. They enable the server to complete all the requests it is currently processing without accepting any new requests.
Integration
These functions allow the state of an SAP server to be changed. The possible server states are described under SAP Application Server States.
Prerequisites
The functions in question are system administration functions that may only be used when a valid username and password are given.
Features
The following functions can be used on the selected servers.
Hard-terminate server
A hard termination is equivalent to a signal 2 on the operating system level. The dispatcher and all its work processes are terminated; requests in the queue are ignored; and requests that are currently being processed are terminated.
Soft-terminate server
All services that the application server provides (updates, batch, and so on) are no longer available, but all requests that are still in the queue are completed by the work processes. Once all requests are completed, the application server terminates.
The server state is then shutdown.
The activate function can no longer be used to activate the server.
Close connection
In this case, the connection between the selected server and the message server is terminated. No more requests from other application servers can reach the server.
This function tests the connection to the message server, because normally the connection has to be re-established.
Deactivate
This has the same effect as soft terminate, except that the server does not shut down when it has finished processing all requests. Instead, it enters the passive state and can be re-started at any time by means of the activate function.
Activate
This is used to re-activate servers in the passive state. The state then returns to active.
Activities
In the initial screen of the Message Server Monitor (transaction SMMS), choose Go To -> Expert Functions -> Server.
Hope this would help you in understanding the concepts.
Please award points if useful.

Sree

Difference between At new and on change statement?

What is the difference between at new and on change statement? Please explain with an example.

hi
on change of differs from at new in the following respects:
It can be used in any loop construct, not just loop at. For example, it can be used within select and endselect, do and enddo, or while and endwhile, as well as inside get events.
A single on change of can be triggered by a change within one or more fields named after of and separated by or. These fields can be elementary fields or field strings. If you are within a loop, these fields do not have to belong to the loop.
When used within a loop, a change in a field to the left of the control level does not trigger a control break.
When used within a loop, fields to the right still contain their original values; they are not changed to contain zeros or asterisks.
You can use else between on change of and endon.
You can use it with loop at it where . . ..
You can use sum with on change of. It sums all numeric fields except the one(s) named after of.
Any values changed within on change of remain changed after endon. The contents of the header line are not restored as they are for at and endat.

Flex List ItemRenderer : Change States from parent ?

Hai there,
So i created a list that uses an arrayCollection as dataProvider and an itemRenderer with 2 states : LabelState and ProgressState, the labelState is the start state and shows a Filename, the progressState is the state i need to change to when i press a "Start Upload" Button.
This is the itemrenderer :
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
autoDrawBackground="true" currentState="LabelState" width="800">
<s:states>
<s:State name="LabelState" />
<s:State name="ProgressState" />
</s:states>
<fx:Declarations>

</fx:Declarations>
<fx:Script>
<![CDATA[
public function changeState():void
trace("changing state for " + label_field.text);
this.currentState = "ProgressState";
trace(this.currentState);
]]>
</fx:Script>
<s:Label name="label_field" paddingLeft="10" maxHeight="40" paddingTop="10" paddingBottom="10" id="label_field" width="800" color="#333333" includeIn="LabelState" text="{data.label}"/>
<mx:ProgressBar id="progress_field" left="3" top="3" bottom="3" mode="manual" chromeColor="#0096FF" includeIn="ProgressState" textAlign="center" labelPlacement="center" maximum="100" color="#FFFFFF" right="3"/>
</s:ItemRenderer>
This is the code for the List :
<s:List keyUp="lst_selected_files_keyUpHandler(event)" skinClass="styles.skins.ListSkinNoHorizontal"
borderVisible="false"
contentBackgroundColor="#c9c9c9" contentBackgroundAlpha="1"
id="lst_selected_files"
width="100%" height="100%"
alternatingItemColors="[#EAEAEA,#FAFAFA]" color="#000000"
itemRenderer="components.ProgressLabel" dataProvider="{arr_items}" />
<components:RemoveBar nr_of_items="{arr_items.length}" id="cmp_removeBar" hermesRYA="cmp_removeBar_hermesRYAHandler(event)" bottom="-35" width="100%" height="35" />
This is the function that changes the states for the current "to be uploaded file":
protected function uploadNextFile():void
if(uploadingFile!=null) uploadingFile==null;
popup = null;
popup = new ProgressPanel();
lst_selected_files.selectedIndex = currentUploadNr;
current_progressItem = lst_selected_files.dataGroup.getElementAt(currentUploadNr) as ProgressLabel;
current_progressItem.changeState();
lst_selected_files.validateNow();
For some reason the states change ... but the elements aren't visually updated, ... meaning that i still see the label and the progressbar isn't visible :/
anyone ?

You will probably want to override getCurrentRendererState() to do this properly tho. This post demonstrates how to use DataRenderer instead if you would rather: http://flexponential.com/2010/02/07/using-datarenderer-to-add-custom-states-to-a-spark-lis t-renderer/
In general you shouldn't interact with the renderers of a List directly (via getElementAt), but rather by changing the data in the List and building an ItemRenderer that reacts to those changes. So it would be better if you did something like list1.dataProvider.getItemAt(0).changeState = true and then in your renderer override the data setter to change the state if that variable is set.

LWAPP changes state to discovery

i have just reset my AP and connect with controller i m getting following error not able to connect with AP or cant access user mode and preveliged mode
%LWAPP-5-CHANGED: LWAPP changed state to DISCOVERY
LWAPP_CLIENT_ERROR: lwapp_name_lookup - Could Not resolve CISCO-LWAPP-CONTROLLER.cisco.com
Translating "CISCO-LWAPP-CONTROLLER.cisco.com"...domain server (10.1.1.20)
how can i resolve it
thanks in advance

Hi,
the recommended way is:
- Set up an DHCP Pool for your Lightweight APs
- Provide the IP address of an DNS Server and the corresponding domain name through this DHCP Pool
- Add an entry in your DNS Server which resolves the name "CISCO-LWAPP-CONTROLLER" to your WLC's IP address
That way, your AP gets an IP adress and the IP address of your DNS Server. When it tries to resolve "CISCO-LWAPP-CONTROLLER" it gets the IP address of your WLC and joins it.
Or you follow the manual way, like leolaohoo described it.
Greets,

Change state with MenuBar component

It's pretty easy to change the state with a button. Example:
click="currentState='AboutScreen'"
But when I try to do this on the MenuBar component, I'm not
having any luck. When I click on the item (let's say Help ->
About), nothing happens. My code is:
click="currentState='menu.student.create_profile'"
I also tried,
itemClick="currentState='menu.student.create_profile'"
No luck.. anyone know how to change states based off items
clicked from the MenuBar?

This should get you started:

%LINK-3-UPDOWN: Interface Dot11Radio0, changed state to down

Hello,
On a 4402 wireless controller (7.0.220.0) with LAP1242AG-E-K9 and LAP1252AG-E-K9 access points I receive lots of messages like this:
Dec 9 12:55:16 ap-a1 1466: AP:001a.2f58.d4d6: *Dec 9 11:55:16.174: %LINK-3-UPDOWN: Interface Dot11Radio0, changed state to down

what is a little bit annoying, in particular for voice communications.
Is there a way to get more information from any logs or is there a similar problem discussion anywhere on this forum?
Thanks.

Hi Konstantin,
Unfortunately I do not think we have the radio status codes published, but I'll comment on them here:
Status 51: Reset on transmit completion. I'm not 100%, but I think this means the radio was supposed to reset (due to another reason) but had data to transmit, so it completed TX and then reset.
Status 52: Reset on completion of multicast packets. Similar to above, just with multicast traffic being queued up.
Status 37: Generic interface reset (up/down), often seen during bootup or on configuration changes.
Status 54: Radio interface was shutdown -- either configured by the user or perhaps part of the boot process.
Status 67: Reset after changing hostname on the AP. This also would occur on bootup once the config is loaded.
Status 71: Reset to update radio status on WLC. Also usually done upon AP joining the WLC after bootup.

Restarting too quickly, changing state to maintenance

I'm trying to add a new resource to stop/start at reboot time. It's a single process that needs to be started, but everytime I enable the resource it keeps stopping and starting it until eventually it goes into maintenance saying "Restarting too quickly, changing state to maintenance".
I have the following in the /lib/svc/method (start) file :

than 'xcomd' or 'svc-xcomd' and it would work. That's
what I've done now. The start/exec and stop/exec now
call a different script. One problem I had with this
was even though when doing a 'listprop' it showed it
had taken the change, and I'd exported it out to the
manifest file, when trying to enable the resource it
would complain that it couldn't find the old script
[ Feb 15 18:12:53 Executing start method ("/lib/svc/method/svc-xcomd") ]
/sbin/sh: /lib/svc/method/svc-xcomd: not found
[ Feb 15 18:12:53 Method "start" exited with status 1]
Is there a way of refreshing things one you make a
change??? When I'm exiting out I'm either using 'end'
or 'exit'.Yes, you have to run "svcadm refresh xcomd". This is
because svc.startd uses the property values from the
"running" snapshot of the service. svcprop does that by
default as well. A plain listprop in svccfg, though, will only
show you the current values of the properties. (You can use
selectsnap to select the running snapshot and examine its
property values with listprop.) svcadm refresh updates the
running snapshot with the current property values, so that must
be done after changing properties.
