Newbie Trying to Identify a Component

Hi I am newbie in electronics and mutisim and i have to create a laser circuit that uses a summing amplfier? (Basically i have it on a sheet in front of me and it is a square box with a plus inside, with input and output connections left and right obviously and an arrow form above aiming down into it)
I cant find this symbol anyway, can anyone help?

Is there any way you could post a picture of what you have? There is a Voltage Summer component under SOURCES>CONTROL_FUNCTION_BLOCKS, but if it has an arrow anywhere on it that sounds to me like current and I don't see any summer/adder for current..
I will post a picture of the Voltage Summer for you to look at. It would help if we had a picture of it as it may be something different than what I am thinking it is.

Identify used component

Hi,
I want to know which component (tab, button, ...) the user klicked on. How can I retrieve this information?
Thanks
Edited by: Alegria on Dec 19, 2007 9:58 AM

You Could have a Hidden Field in your form and have the hidden field updated through Javascript with the ID/name of the tab or button which the User clicked and bind that hidden field to backing bean property. Use that property to identify which component was clicked.
Thanks

Trying to identify what to change for user who has permissions on a library but gets no search results from the library

We are running SP 2010 service pack 2.
Search is working for people in general.
Yesterday user Y asked me why they (user Y) does not get results when they search for documents in the library. They get results back when searching other libraries.
The library has a limited number of users who can access.
The user is explicitly added to the library's permissions with Read permission.
When I look inside the library at specific documents, the user is listed as having Contribute,Limited Access privs on each document.
As an admin, I have accessed the site and performed searches and gotten results. Others on the site with various permissions get results back.
So it appears that search is working.
What other things can I check - via powershell perhaps - to help identify and resolve user Y's dilemma?

What we found is this.
At the site level, only 4 users have access. At the library level, 3 more users were added directly and given read permission.
These three users could see the contents of the library, read the documents of the library, but when they attempted to search the library, got "Access Denied".
I was able to negotiate for a resolution of this problem for us to create a new SharePoint group for the site, give it Read permissions,
and add that group to the library permissions. I informed the owner that he could check other libraries and lists and remove that group if there were things there that should not be accesible.
I also warned him that if he were to put something confidential in, say, the announcements section, he would need to remove the group from that list as well if he didn't want the people to see that.
So, the users now can see the results page, which is returned as a URL immediately under the site.
There were a couple other work arounds that we could have tried - moving the shared library to its own subsite with different permissions than the parent site, or having the users use the enterprise search and to refine the results down to the specific library.
Thank you for your question!.

Problem identified jsf component and problem of checkboxs

hello,
i have 2 questions:
- 1
I have a js function that show/don't show a tab when we chose yes/no on a SelectOneRadio:
function display(fieldRadio,tabtohide)
div = document.getElementById(tabtohide);
if(fieldradio.value=='false')
div.className='hide';
else div.className='';
I call this function in the radio component, like this:
onclick="display(this,'tabid');" and it works very well.
The problem is that i would like to replace 'this' by the id of the component (to call this function at another place).
I'v tried the document.getElementById(JsfTagId); but it doesn't work with jsf tag.
- 2
I use a selectmanycheckbox like this:
<h:selectManyCheckbox value="#{BeanDemandeur.type}" required="false">
<f:selectItem itemValue="Nouvelleinstallation" itemLabel="Nouvelle installation"/>
<f:selectItem itemValue="Mise�jour" itemLabel="Mise � jour"/>
<f:attribute name="fieldRef" value="Type de demande"/>
</h:selectManyCheckbox>
In the bean, i use the variable type like this:
private String[] type = new String[2];
public String[] getType(){return type;}
public void setType(String[] rr){type[0]=rr[0];type[1]=rr[1];}
And finally, in th faces-config.xml:
<managed-property>
<property-name>type</property-name>
<property-class>java.lang.String[]</property-class>
<value/>
</managed-property>
But an error occured: Can't set managed bean property:'type';
thx u for your help

Newbie trying to use tomcat to run jsp

I'm just trying to setup Tomcat on my machine, and i've run into a couple of issues.
(1) if i type in http://localhost:9000/test in IE, it gives me an error saying TCP_ERROR and how the web server is possibly down. however if i try it in Netscape, the page shows up fine. I read in the running.txt file that it had something to do with the LAN settings, but i have no idea what has to be done in there to get it to work??
(2) the second issue is, if i give someone the url http://<IP>:9000/test that is using another machine, what has to be done for them to see it? i had someone on another machine try it and they got page could not be found.
TIA

>
(1) if i type in http://localhost:9000/test in IE, it
gives me an error saying TCP_ERROR and how the web
server is possibly down. Do you mean HTTP 500 error?

Netscape, the page shows up fine. I read in the
running.txt file that it had something to do with the
LAN settings, but i have no idea what has to be done
in there to get it to work??
No LAN settings are needed. You're doing something else wrong. Is there a TOMCAT_HOME/webapps/test directory set up? Unless you created it, there's no such URL in Tomcat's setup.
(2) the second issue is, if i give someone the url
http://<IP>:9000/test that is using another machine,
what has to be done for them to see it? i had someone
on another machine try it and they got page could not
be found.
TIA If they can see the machine on the network, you don't have to do anything else special. If they can ping it, they can talk to Tomcat.
If you're a newbie, as your topic says, why are you changing things like the Tomcat port? Leave it as the default until you have Tomcat under your belt. - MOD

Newbie trying to write toplink hello world program

I am trying to write my first toplink app using POJOs, and I'm having a hard time finding a sample toplink application. In this case, I'd like to run outside of a J2EE container with a stand-alone java application to do some basic CRUD operations. I've already run the mapping workbench on my Java classes and generated the deployment file and sessions.xml file. Where (Oracle docs) can I find source code for a simple stand-alone java main() app that uses the toplink API?
Thanks in advance.

TopLink ships with many examples - complete with runtime and workbench componants - in 9.0.4.X Find them here: <TopLink_install_dir>\examples\
For non app server simple CRUD examples, I suggest you look here first:
<TopLink_install_dir>\examples\foundation\threetier

Can't help you there, I'm afraid, and I don't do development since many years back so I'm pretty useless in that area ;-)
However, since the Net layers are beneath OCI in the stack, I would think that if these certificates work at all with Oracle (via some other client, like SQL*Plus), it should work with all types of apps.
But, I believe the Pro* stuff is not all that up to date, so if connectivity requires 10g features, there's a small risk of incompatibility issues.

Hi,
I have couple of doubts.
1. I put <grid> component inside of <List>
component . Surprise! The <List> component is not identifying
the <Grid> component. Is this bug of Flex Or it's property of
Flex <List> component.
What I have to do to make <Grid> visible even I put
inside of <List> component.
2. what is an equilanat of <Table> in Flex. Ofcourse it
may be DataGrid. Suppose If I use DataGrid I have lot of
restrictions.
These are the problems I am facing with <DataGrid>
( i ) Is this possible to put radio button / link bar as one
of column in a row. I mean how to put radio button / link bar as
row in array
( ii ) Is it possible to make columns in a row as variable
sizes i.e. suppose if DataGrid header has size=100. Is it possible
to make column of next row size as 200.
anybody help me in this regard. I am eagarly waiting for
reply.Because I have been strugling to solve this problem for last
4 days.
Regards,
Siva Kumar

A custom itemRenderer will be the solution to several of your
issues(1,i).
For 2., there is no exact equivalent of an html table. Look
at Grid, TileList, or consider making your own component.
for ii), no, all cells in a columns must be the same size.

Newbie: Trying to get data from Code Behind file to HTML file.

Greetings,
I am trying to use the opener link adaptive tag to open a specific page. I have the Object ID, and classID as variables in my class in my class file, but I do not know how to get that data into the opener link which is on the html page.
Should I be using session variables? If so how, I am a newbie.
Does anyone know how?
Thanks.

Kinda depends on your flavor/need/preference. I've done it...
* Using session variables and just writing to the page in script blocks. Not preferred in .NET-land, but definitely more of the fast/traditional ASP style. Use sparingly and with caution. Be really careful about VS.NET totally destroying your tags. It seems to love doing that (as an aside - HUGE thank-yous to the BEA engineers who altered the tags to consistenly use lower case. Really. I can't thank you enough. :) )
* Using label controls and then just populating the label with the formatted adaptive tag (this can work well)
* One of our guys did a really simple/elegant server control that takes arguments for the objectid, classid, etc. Nice for creating things repeatedly server-side and gets you by the HTML, quotes, etc. all over the place. Nice as it also consolidates the tag in a single place you can alter once.
For session variables, you'd just do something like...
<%
'//in your code-behind
Session("myClassID") = 18
Session("myObjectID") = 12345
%>

<pt:standard.openerlink xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/' pt:objectid='<%=Session("myObjectID")%>' pt:classid='<%=Session("myClassID")%>' pt:mode='2' target='myWindow' onclick=window.top.open('','myWindow','height=800,width=700,status=no,toolbar=no,menubar=no, location=no');>Adaptive Tags Made This Easy - Click to Open My Awesome Document</pt:standard.openerlink>
That help?
Personal style, I would try to avoid using session, etc. directly on your ASPX file. I'd go with writing out the HTML through labels, data lists, etc. in your code-behind.
Thanks,
Eric

GoLive Crashing when trying to update a Component!!! Help

Anyone have any ideas on why this would be happening??? The Component I am trying to update is "Navbar.html" ... the Update box comes up like it is supposed to .. but then I get the "GoLive has encountered a problem and must shut down .... "
This is getting SO frustrating!!!
Any help would be apprecitated!
Kathy

Does it seem to be happening on the first page it tries to update? Or, can you tell if it's crashing while trying to update a certain page? That usually means GoLive is running into something it doesn't understand (like a syntax error in either the Component or one of the pages it's trying to update). Not always the case, but it's probably the best thing to look for.

Help needed- newbie trying to setup xerces XML pasrer

Hello all,
I am new to Java and XML.
I am trying to write a simple java program that will use the xerces parser and will read the XML file.
I have installed xerces 2.8.0 and put in on a specific location on my hard drive.
I also added the xercesImpl.jar file to the CLASSPATH variable.
I am trying to compile this code:
import org.xml.sax.XMLReader;
public class SAXParserDemo {
public void performDemo(String uri) {
System.out.println("Parsing XML File: " + uri + "\n\n");
// Instantiate a parser
XMLReader parser = new SAXParser();
public static void main(String[] args)
if (args.length != 1)
System.out.println("Usage: java SAXParserDemo [XML URI]");
System.exit(0);
}//IF
String uri = args[0];
SAXParserDemo parserDemo = new SAXParserDemo();
parserDemo.performDemo(uri);
}//MAIN
The error I get is on this line : XMLReader parser = new SAXParser(); stating that it cannot find SAXParser.
What am I doing wrong? is there something else I need to import?
Help will be much appreciated.
Sorry for the newbie question.
Cheers,
Mike

The error I get is on this line : XMLReader parser =
new SAXParser(); stating that it cannot find
SAXParser.
What am I doing wrong? is there something else I need
to import?Well, yeah. Your code shows you already know how to use the "import" statement. The compiler says it can't find SAXParser, and you correctly suspect that you need to import something. So the logical step: you need to import SAXParser.
But you don't know what package it's in, right? Well let me just look it up in the API documentation for you... here it is... javax.xml.parsers.SAXParser. Take note of the existence of documentation for the next time you have this sort of question.

Trying to identify a MSI motherboard

A friend gave me his PC & I am gonna format its hard drive and reload XP from scratch on it. Also, they want me to max out its RAM. I originally thought it was a DELL 3000 desktop & could hold 2GB of RAM, but after talking to him, I learned that the motherboard had been replaced a while back. He told me his original DELL computer got zapped by a storm so he had to have the motherboard replaced. Its now apparently an MSI motherboard since I can see a big "MSI" printed on it after I open the case.
Since I'm not sure exactly what motherboard is in there, what is the best way to identify it? I've seen the free scanner on MSI's website that helps identify it and be able to tell you what drivers it needs (something I will need to use as well), but is there maybe a free MSI download that can tell me what I have and identify the motherboard part number. Therefore, I can then determine how much memory it can hold and what I need to buy. Or maybe there is something else I should simply look for physically printed on the motherboard?

OK, got it and found the driver page. Its a PM8M-V motherboard and here is the driver page for it.
http://www.msi.com/product/mb/PM8M-V.html#/?div=Driver&os=XP%2032
However, I am now having an issue with one of the drivers. 32bit XP & here is what I needed & have successfully installed so far:
- chipset driver (very first thing to install)
- audio driver
Also downloaded & installed XP Service Pack 3. Now, I tried installing the video driver listed on this support page (for its integrated video). I tried running the 'setup' file, but that didn't work. It keeps giving me a message saying that it was unable to load the software and to go to the Windows directory log for details. It then aborts the installation. What is this? I tried to install the video driver manually, but that didn't work either.
I even tried running the live update 5 software in automatic mode, but that apparently didn't work either & I am still getting a yellow question mark for video in the device manager. Any idea what is going on here and how to install this motherboard's video driver properly?

Mac newbie trying to figure out best internal HD configuration

Greetings,
I've been trying to educate myself about internal hard drives by reading some of the posts here and doing a search about RAID but unfortunately I'm still a little confused. I'll try to post my questions about what I'd like to accomplish and if these have been answered before I'll gladly go read a post if someone can direct me to the right place.
First, I have only one internal hard drive on my MacPro and I'm tired of living dangerously! I need to install another hard drive to use as a backup of my work, digital images, music, etc.
1. Can someone explain (or link me to an explantion) the differences of RAID and which one i would want for the above scenario?
2. Given my original aim with the backup disc, can someone recommend a make/model that works well as a backup? (for example i read about differences between an SE and an RE drive from one manufacturer, and how one works better in this or that situation, but it all went right over my head)
3. Is there a software application I should consider that will help me automate my backup process on a daily (nightly) basis? (I'm more than a little forgetful)
Thanks very much for dealing with the newbie on these issues!
Enjoy the day,
Pedro
MacPro 2x2.66 GHz Mac OS X (10.4.9)

I don't use raid myself so I'll leave that explanation to others. I configure my Mac Pro with 4 drives. My main drive is my boot drive and has about 300+ gigs free. I have a backup drive for that which I use SuperDuper for backup, creating a fully bootable backup drive in the event my main drive has a problem. I only back up to that drive when my machine is "good and solid". That allows me to throw on the most recent update without much concern. If there is a problem then I just boot from my backup drive and I'm back up and running just fine. I also use the backup of my main drive for my Final Cut Pro scratch drive. I copy the files for my movies to external drives for archive when needed. For my data drives I use another set of 500 gig drives. One for data (mostly photos) and one to backup using superduper whenever I feel like it. You could automate it all with Retrospect for the data drives if you wanted to. I don't think Retrospect will make a bootable backup of a main drive. I use Western Digital WD5000KS ddrives, 500 megs each. They make another model for those wanting RAID. Set up RAID, by all means, if squeeking every ounce of speed is your goal to be sure. My setup is conservative, redundant and very safe. A simple search here or on google for RAID0 or such will turn up much info on raid configuations.
