Design a possible set up to simulate the vibrations of a suspension
Hello everybody,
I have no clue how can I solve this lab practice (Pinctures attach) . I guess I have to set up the rotary potentiometer to act like a suspension, Do you have any idea where should I start?
If you guys have any solved examples in labview will help al lot to understand.
Any help is welcome,
Best regards,
Julen

As your second picture shows, the objecive of this final lab exercise is to "employ all acqured knowledge".
Since you seem completely stumped, It looks like you have not acqured any knowledge and are thus not ready to pass this course. You can't just jump into the deep end at this stage. I would recommend to go over the course material. All information should be there.

Hi .
I was creating the pass the values t in temp tables though s sis package vs2012 .
First I was taken on executive SQL TASK.
IN EXCUTIVE SQL TASK . I was write the stored proce:
Sp;
reate procedure USP_GETEMP2333
AS
begin
Select eid,ename,dept,salary from emp
end;
create table #temp(eid int,ename varchar(20),dept varchar(20),salary int)
insert into #temp
exec USP_GETMP02333
go.
It was executive correctly.
I was taken another sequence container. In the sequence container iam creating one executive sql
In 2<sup>nd</sup> excutive sql task: sql statements is
if object_id('emp_fact_sal') is not null
drop table emp_fact_sal
select eid,ename as emp_name,sal_bar=
case when salary<=5000 then 'l'
when salary >5000 and salary<=7000 then 'm'
else
'h'
end
into emp_fact_sal from #temp.
and one falt flies it was taken to designation .
iam changing all connection properties:
in oldeb connection:
in excutive sal task properties .
delay validation is true,
and retain connection maner is also true,
and package mode is 64 bit is false.
But iwas excutive in 2<sup>nd</sup> excutive ql task .
Iam getting this type of errors,
[Execute SQL Task] Error: Executing the query " if object_id('emp_fact_sal') is not null

correctly.
Please help meArthur suggestion works but you shouldnt even be doing this on a SQL Task.
Use a data flow task. You'll have better control over the data that is being transfered and get better performance because no staging table will be used.
Just because there are clouds in the sky it doesn't mean it isn't blue. But someone will come and argue that in addition to clouds, birds, airplanes, pollution, sunsets, daltonism and nuclear bombs, all adding different colours to the sky, this
is an undocumented behavior and should not be relied upon. -

My client with autism needs to be able to speak/sing into a microphone and simultaneously hear his voice through a headset, preferably with reverb set on high. Is it possible to do this with the iPad and OS7? If so, what setup do I need? I have a SM58 type mic and-over-the ear headphones.
This implies that ODP.NET does NOT need to be installed on a client. However, I cannot find OraOPs9.dll on a machine with Client Release 9.2 installed. Should OraOps?.dll automatically come with a Client installation of 9.2 or higher?
ODP.NET needs to be installed on the client. OraOps9.dll is part of ODP.NET, not the Oracle Client.
Also, if an application is built with the 10g ODP.NET, can it be run from a machine with OraOps9.dll?
If an application is built with 10g ODP.NET, it can be run with 9.2 ODP.NET as long as you do not use any 10g APIs. The new features in 10g ODP.NET are included in the doc and the ODP.NET FAQ for your reference. -

This is frustrating and needs to be fixed ASAP and addressed by Apple.
By the way, Apple told me to bring my device to the Apple Store because it's still under warranty. That's great and all, but I'm going to waste my time if there is no fix for this issue.
Ok so you want Apple to address the problem, but yet you don't want to take it to them just in case they can't fix it? What if they can fix it? Complaining here certainly won't fix it. -

How to set a cookie in the browser from an html page called via an Iview
Hello all,
I have an issue which is causing problems. I have a snap survey (html form with submit and cookie setting) which is embedded in a url iview.
Although the submit and the form work fine, the portal will not allow the cookie to be set it seems.
Is there a way to allow cookies to be set from an embedded page in a url iview??
You will make my day if you know!
System: EP7 SP13
Kind regards
AlexHi,
Check this:
http://www.oracle.com/technology/products/ias/portal/html/same_cookie_domain_with_pdkv2.html
Cookie Basics
Web browsers have built in rules for receiving and sending cookies. When a browser makes a request to a web server and the web server returns cookies with the response, the browser will only accept a cookie if the domain associated with the cookie matches that of the original request. Similarly, when a browser makes a subsequent request, it will only send those cookies whose domain matches that of the target web server.
These rules are designed to ensure that information encoded in cookies is only "seen" by the web server(s) that the originator of the cookie intended. These rules also ensure that the cookie cannot be corrupted or imitated by another server. By default, the domain associated with a cookie exactly matches that of the server that created it. However, it is possible to modify the domain at the time the cookie is created. Relaxing the cookie domain increases the scope of the cookie's visibility making it available to a wider "audience" of web servers.
For example, if a cookie is created by a.us.oracle.com, it's domain will usually be set to a.us.oracle.com. This means that the browser will only send the cookie to a.us.oracle.com. It will never send it to any other servers. However, if at the time of creation, the domain of the cookie is set to .us.oracle.com, the browser will send the cookie to any server whose domain falls within .us.oracle.com. such as portal.us.oracle.com, provider.us.oracle.com, app.us.oracle.com etc

Setting BitmapImage source inside the skin
Hi all
As a Flex 4 newbie, I've been banging my head for two days trying do to something that could seem pretty trivial to you (and to me as well at first sight) but lefted me completely clueless...
I want to design a fairly simple custom component using the Gumbo architecture. My component falls into 2 parts:
* a logo picture on the left side
* a buttonbar next on the right side
My component must be designed to be quite generic, that is to say the source of the logo image is a property of the component as well as the items of the ButtonBar.
So here is what I did so far:
I wrote an AS class describing the behavior of my component "MapToolBar.as":
package nova.style
import spark.components.ButtonBar;
import spark.components.supportClasses.SkinnableComponent;
import spark.primitives.BitmapImage;
[SkinState("normal")]
[SkinState("disabled")]
public class MapToolBar extends SkinnableComponent
// Define skin parts
[SkinPart(required="false")]
public var clientLogo:BitmapImage;
[SkinPart(required="true")]
public var tools:ButtonBar;
// Define component data
private var _logoSrc:String;
public function set logoSrc(src:String):void {
_logoSrc=src;
[Bindable]
public function get logoSrc():String {
return _logoSrc;
private var _toolsItems:Array;
public function set toolsItems(items:Array):void {
_toolsItems=items;
[Bindable]
public function get toolsItems():Array {
return _toolsItems;
public function MapToolBar()
super();
override protected function getCurrentSkinState():String {
if (enabled) {
return "normal";
} else {
return "disabled";
And the associated skin mxml class:
<?xml version="1.0" encoding="utf-8"?>
<s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

<!-- Place non-visual elements (e.g., services, value objects) here -->

import nova.style.skins.ToolBarSkin;
// Initialise les données des skinparts après leur création.

tools.dataProvider = new ArrayList(hostComponent.toolsItems);

<s:ButtonBar id="tools" skinClass="nova.style.skins.ToolBarSkin"/>
</s:HGroup>
</s:SparkSkin>
As you can notice, my inner ButtonBar has got its own skinClass has well. This is because I'm trying to divide my application in as many reusable bricks as possible. So here's ToolBarSkin:
<?xml version="1.0" encoding="utf-8"?>
<s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" alpha.disabled="0.5" xmlns:mx="library://ns.adobe.com/flex/halo">

Finally, in my main application I invoke my component like this :
<nova:MapToolBar logoSrc="@Embed(source='/assets/img/clients/ge.png')" skinClass="nova.style.MapToolBarSkin">

<s:ButtonBarButton id="redBtn"
label="Red"

/>
<s:ButtonBarButton id="orangeBtn"
label="Orange"

/>
<s:ButtonBarButton id="yelloyBtn"
label="Yellow"
data="@Embed(source='/assets/img/nuclear.png')"
/>
</nova:toolsItems>
</nova:MapToolBar>
Unfortunately,I get the following at runtime:
* the logo image is never displayed - yet the path is correct and the step-by-step debug confirms that the handleCreationComplete() method gets called with correct values being assigned to my parts !
* each buttonbarbutton throws this stackexception, and of course my button icons aren't displayed either, only buttons' backgrounds show up:

Any help would be really much appreciated
Thanks
MattWell, I've already solved one of the two issues
In order to display the icons on my buttonbar buttons, I just needed to point at {hostComponent.data.data} instead of {hostComponent.data}. I'm not sure why, but {hostComponent.data} in my skin class is a handle on my instance of ButtonBarButton, not its "data" property. Any explanation is welcomed
I still have got the first issue though. Oddly enough my design works if I put an mx Image instead of the spark BitmapImage for the client logo. That will do the trick for the moment but I'd prefer to deliver a 100% pure spark component in my prototype, and I can see no reason why BitmapImage works inside my ButtonBarButtons and doesn't otherwise... -
Which EQ setting + volume level is the most 'clear'?
Hi
Just got an iPod Classic this week (my first ever Apple Product other than iTunes). It's replacing a 30G player from another company from 2006 (ran out of room) that had really good sound. With a simple pair of JVC Marshmallow earbuds, the right mid-volume and the right EQ setting, I could hear all the musical instruments clearly and somewhat equally and the singer's voice was clear as well, as if we were in the same room.
I'd like to recreate this with my iPod Classic but I've noticed the EQ isn't customizable (unless I'm missing something) and that with some of the iPod's EQ settings I can hear instruments clearly but the vocals sound muffled, almost like they're dubbed from another source. But there's other settings (Vocal) where the singer comes in clear but the instruments are muffled in that dubbed way. I've tried Flat and Off but results with those vary.
My old player's EQ was set at a reverse of the iPod's Rock setting, lowest bars on the outside and highest in the middle. Is it possible to load an EQ setting like that from iTunes? If you can download a game, can you download an EQ setting?
AND is there a certain volume level where that 'same room' clarity shines through? Anything lower than 11 out of 20 on my old player and it would lose that clarity (anything higher than 13/20 was too loud). 12 was just right. If that makes any sense.
Or could it have something to do with how a song is ripped from a CD? Which is what my music collection started out as.
I'm hoping someone can help and shed some light on this for me. I got it engraved so I can't exactly return it. haha
tangcameoMost audiophiles, switch off the iPod Classic EQ as it is crap, most probably designed by some team who like bubble-gum music. but if you must use, create a custom EQ presets
read this forum
http://www.head-fi.org/t/399487/ipod-custom-eq-yes-it-can-be-done
But try not to boost up greater than zero db, the new iPod audio chipset don't like it, your music will sound like something from some Oriental Opera, of course, unless you like the metallic tin highs. -
How to set up and test the Basic Authentication for HTTP protocol
Hi,
I tried configuring the password based Basic Authentication for sending xml document using ebMS - HTTP protocol. I set username and password while configuring the transport server for both trading partners. I want to know, is that sufficient for basic authenticaton. When I open the URI http://localhost:7778/b2b/transportServlet, it is not asking any authentication (username/password). Please note that I have not used SSL certificate. Anyone please help me out to configure Basic authentication.Hi Ramesh,
Thanks for ur response. Could you please tell me where to set the Additional Transport header : authtype-basic#realm=myRealm(in which property file). In enqueue code, I could see the following attributes
queue
msgID
replyToMsgID
from
to
eventName
doctypeName
doctypeRevision
msgType
payload
attachment
subscriber
Is it possible to set username/password in the enqueue attributes?
Do i need to add username/password and Transport header in the input XML and defined that elements in xsd? -
How can two independent DirectAccess servers be set up safely in the same domain?
I've got a single-tier certificate authority running on a 2008 r2 domain controller with an expiring root certificate. I have a new 2012 r2 domain controller with a new single-tier certificate authority. I also have a DirectAccess server running on 2012
server (two NICs, NAT, IP-HTTPS only). I'd like to get a new DirectAccess server set up running server 2012 r2 using the new CA for the various DirectAccess server and client computer certs. I can get the new environment working and flip machines from
the existing implementation to the new implementation.
I was previously told by a tech working one of my Microsoft support tickets that two independent DirectAccess servers can't run in the same domain. However, I posted a related question
https://social.technet.microsoft.com/Forums/projectserver/en-US/ab53a314-91ea-4d40-afd5-6b8f62698547/2012-directaccess-and-expiring-certificate-authority?forum=winserverNIS and got a response indicating that two independent DirectAccess servers can run
in the same domain. If I can carefully get a second server operational within the same domain, I can build a reg file to deploy to all machines prior to the cutover that will simulate the gpupdate for broken machines in the field, getting them connected so
the policy can be properly pulled from a DC. Would anyone else be willing to confirm or elaborate on operating two independent DirectAccess servers in the same domain? What are the gotchas?Hi,
Yes you can have 2 Da deployments in one domain.
I have done this a number of times for customer when upgrading from UAG DA to 2012.
Make sure you use different Group policies for the DA servers and Clients. make sure you target the client with only one GPO at a time. Also use different AD groups.
You then change the GPO assignment to the clients and they will flip when the client does a gp update. I have done this for a site that had over 5000 clients and we didn't have one call about it.
You can use DirectAccess Offline Domain Join for any broken machines.

How to implement Modbus Ethernet communication in Lookout, if we want to simulate the PC as PLC ?
Problem Description :
Dear Sir,
We are doing a project where we are using Lookout with
Front end Modicon PLC. The communication is by
Ethernet, using Modbus.
Since the installation is at a distant place, we wanted
to use another PC (running Lookout) to simulate the
PLC. For this, we tried to communicate
a: the server Lookout PC running Modbus Ethernet mode of
Modbus object as Master
b: with another PC (for simulating the PLC) running
Modbus Slave
We did not get any communication. (we have given the
details of what we have done, at the end of this email)
We also tried connecting the above 2 PC's as
a: the server Lookout PC running Modbus Serial mode of
Modbus object as Master
b: with another PC (for simulating the PLC) running
Modbus Slave object
Again we did not get any communication.
If instead of PC (b) we connect the Modbus simulator to
PC (a), there is no problem in communicating
Please let us know how to go about establishing the
communication between 2 PC's using Modbus serial,
and Modbus Ethernet. A detailed step by step procedure
would help us a lot.
Thanking you
Warm Regards
Raja Mahbubani
Procedure of our trial with ethernet.
This is what we have done in detail.
On PC A:
We created an object (Pot) and connected it to
the modbus data member of the modbus object say 40001. In the
properties of the modbus object we selected modbus ethernet mode
of communication and in the IP address field we wrote the IP
address of the machine B to which we are trying to communicate
i.e. 152.63.50.2.
On PC B: we tried the following two methods
Trial 1 : We created a modbus slave object and
inserted an expression for the same data memeber to which the
object was connected hoping to get the value of the pot of machine
A on machine B.
Trial 2 : We created a modbus object on machine B and we wrote
the IP address of machine A and inserted an expression for the
same datamemeber to which the object was connected hoping to get
the value of the pot of machine A on machine B.

Ph: (+91) 20 4222556/7The ModbusSlave which comes with Lookout currently supports only Serial communication. So, you cannot use Ethernet between your two PCs. At least not with Modbus Master-Slave setup (if you must speak Ethernet between the two PCs, IPASCII object lets you do that, but then you'll need to implement your own protocol).
Since all you want to do is simulate a Modbus PLC on a PC, you can use the Serial mode of communication for now. And later on just modify the Object in your Server Lookout to use the Ethernet mode.
For setting up a Serial Modbus Slave, use a null-modem cable between the two PCs (lines 2 and 3 are swapped). On your PC 'B,' create the Modbus Slave object with the right COM port for that PC. And on your PC 'A' create the regular Modbus Object as if you w
ere connecting to the Modbus Simulator box. The only difference here is the cable. The simulator box uses a straight-through cable whereas the Slave needs a null-modem cable.
Hope this helps.

Setting a wallpaper using the iPhone SDK
I am looking for a way to set an image as the wallpaper for the user. For example, when the user took a picture with his camera, I want to present him with an UIActionSheet where he can choose wether to save his picture to the photo library or set it as a Wallpaper on his phone.
Is this possible with the SDK, I can't find any reference to Wallpapers in the SDK documentation.Don't really know if this is appropriate, but a little kick to get back on the first page.

Set as default value the Item Category in the Maintenance Order
Hello everyone,
We are trying to find a user exit in order to set as default value the item category in the Maintenance Order once the Material has been introduced (Tag Components).
SAP Customizing let the user set the Item Category automatically per Material Type, but we need to set different Item Categories to materials belonging to the same material type.
We would really appreciate any help relating this issue.
Thank you very much,
Víctor LiedoDear Paul,
Thank you very much for your response.
I had already tried customizing mentioned by Pithan, but it did not work because we need to set different Item Categories for Materials with same Material Type.
We have been searching for exits which may let us set Item Category in the Maintenance Order, but it does not seem to be possible.
What you say about adding some custom validation through user exit, not to set item category as default value, but to check if the one entered is valid, sounds the best way of achieving our commitments.
I have tried to look for CNEX0037 & CNEX0038, by using transactions SE37 and SE38, search for programs and functions modules, but it did not work. Could you please tell us what kind of objects are?
Thank you very much in advance.
