HELP needed creating a Network Monitor using JSNMP

I would really appreciate if anyone could help me. I'm currently TRYING to develop my final year college project- A network monitor using JSNMP. I don't know how to go about pinging a device using this. Can anyone help me pleez?

Did you try to build and run their examples? Check out the example called SNMPV*TrapSenderTest where * is the SNMP version you want to use.

Help Needed Created Standalone Network for iTunes DJ

I use my MBP to manage backing tracks for a band. I would like to use iTunes DJ for requests from the audience via wireless connection via *iPhone/iPod Touch Remote app*. I would use this option in conjunction with a printed song list and small request cards (for those who don't have iPhones).
I can't connect to an existing network as most venues do not have wireless. I would like to set up my MBP as a wireless base station that can be accessed via an iPhone/iPod Remote app. Besides, I would prefer to have a network that echo's the band's name.
I know I have to use the "*Create computer-to-computer Networks*", but I am unsure of what settings I need to get the network working.
I will use Locations to quickly activate the MBP as the base station.
Any help or suggestion setting up my MBP as a wireless base station would be greatly appreciated.
TIA

Agreed. I'd keep at it yourself. I guarantee it will be something simple.
what are the benefits of a switcher? (never used one before) any recomends?
A switch is just like a hub, except that instead of always sending packets to your entire network, it only sends them where they need to go. The benefits grow with the size and speed of your network. Switches used to be much more expensive than hubs but not any more. Normally I'd recommend almost any Linksys device, but in this case dlink seems to have a better one:

Again, I don't think your dlink hub is responsible for this dramatic bottleneck though.

Help needed creating vertical bullet list using div tag and css

Hi,
I think there is something quite fundamental that I'm missing when using div tags - I seem to keep running into problems with them.
I'm trying to create a vertical bullet list. It works fine when I try the code on its own as follows:

When I insert that into my site template page, its all over the place:
http://www.pa-solutions.co.uk/development.html
I've put the css code into a seperate file http://www.pa-solutions.co.uk/pas.css - I get the same results when its embedded into the html doc.
Please help before I pull all my hair out.
Thanks,
Phil.

Unless you know what you're doing with absolute positioning, avoid absolute positioning! Absolute positioning actually takes an element out of the normal HTML document flow and positions it absolutely in relationship with it's first parent with a position other than static - for details read the HTML specs at the W3C.
Ideally you should use the normal HTML document flow. Divs are block level elements meaning that they act like blocks that take up a height (determined by children content) and width (the full width of the page or it's parent container, unless you tell it otherwise).
For your CSS try this:
#techlistcontainer {
    width: 75%;
    margin-top: 0;
    margin-right: 0;
    margin-bottom: 0;
    margin-left: 30;
    padding-top: 0;
    padding-right: 0;
    padding-bottom: 0;
    padding-left: 30;
How does that work with your templates?

How to create multi instance monitoring using VSAE

i have a class and it has multiple instances which inturn has data about each and every instance as performance logs etc
i need to get the data about each every instance and add some property bag data appropraitely.
how can i achieve this, how can i create multi instance monitoring in VSAE and how to create rules for multi instance.
SCOM Version:SCOM 2012 R2
Thanks & Regards, Suresh Gaddam

Hi
the discovery of the class will populate the class object property's and discovery can discovery multi instance of class, make sure there is a key property for class.
once you target a rule or monitor a workflow will be create for each instance, as the rule target to the class you can pass class instance and host class property's as parameters.
for examples check below link

Help needed in Multiple Receivers sceenarios using BPM

Hi,
I am new to BPM. As per my requirement, based on a business logic i may split the messages into two at message mapping. If i have spitted the messages into two, it should go to different receivers. Or if my logic hasnt splitted the mesaage means it should go to any one of the receivers. I also expect response from the receiver system once its done successfully.
Could you help me how to do this using BPM?
Thanks & Regards,
Senthil.

Hi,
You can do it without BPM also, by using MultiMapping. If only splitting is required then I would suggest not to use BPM since it will consume much memory. Instead you can use multmapping.
For Multimapping, go to messages tab in message mapping and select your different target structures and map it as per your requirement. In Integration Directory, go to advanced Interface Determination and proceed.

Help needed, Createing Dynamic User input

Hello,
I am attempting to create some dynamic user input by "predicting" what the user requires in a text box.
For example if the user enters "Smi" I have a select list pop up which gives the user all options that begin with "Smi".
I am able to achieve the popups but the interface is quite jerky and not terribly responsive I am trying to solve this by using a thread which starts and stops when new input is received but it is still not quite right.
The program uses a Sorted TreeSet to hold the data (I thought this would give me a quick search time) and a simple interface at this stage.
Any help would be fantastic
Thanks in advance :P

Help in creating MDX Calculated Member using attributes from multiple Dimension

Hi All,
First of all my knowledge on MDX is basic. In one of our projects, there is a requirement to create calculated member (similar to derived fields in SQL) which is more of a dimension attribute and not really a calculated member. Due to IP issues I cannot paste
the actual queries but I will provide an SQL Query equivalent to what I am trying to achieve:
Select P.Product, Case When ISNULL(FS.ArtistName,'') = '' Then P.ArtistName Else FS.ArtistName End Artist
From
dbo.FactMusicSales FS
Join dbo.dimProduct P
on P.DimProductKey = FS.DimProductKey
We are trying to replicate the logic for derving the "Artist" field using MDX script.
We are running into issues while trying to build an MDX expression using the above logic. The main issue being that the new field/member "Artist" would not be calculated unless its elements are selected (FS.ArtistName, P.ArtistName). Besides this
we are also unable to place this new member in a different folder other than a sub folder under the measures. Any pointers to solving this would be really helpful.
Thanks in Advance,
Venki

Hi Venki,
According to your description, you need to create calculated member (similar to derived fields in SQL) which is more of a dimension attribute and not really a calculated member, right?
In your scenario, you needn't to achieve this requirement by using MDX. You can use a named query on your data source view. A named query is a SQL expression represented as a table. In a named query, you can specify an SQL expression to select rows and columns
returned from one or more tables in one or more data sources. So in you scenario, you can use your query on the DSV, and then use the modified table to create a dimension.

Help needed creating Web Service Proxy with SSL

Hi All, I really need your help. I need to create a Web Service proxy for a web service which is SSL enabled and developed in Netbeans. I have been given keystore as well as certificates files and I have copied "keystore.jks" in my c:\Documents and Settings\<user> and the certifcates to <JAVA_HOME>\jre\lib\security\cacerts. Now when I run the Proxy creation wizard and give the location of the WSDL file, JDeveloper gives an error "Error importing schemas: Default SSL Context init failed: Invalid keystore format". Can anyone please guide me what I am doing wrong here. I will appreciate your help.
Thanks in advance.

I am using JDeveloper 10.1.3.3.0. Thanks Heaps

Basic help needed creating a trigger

I'm completely new to SQL programming altogether, and I'm trying to set up a trigger that will make some checks before adding a new row to a given table. I am trying to do this because I need to enforce a CONSTRAINT that checks whether the dates entered for 'deadline' and 'startDate' are greater than sysdate and less than (sysdate + 365), and I found out that you cannot reference sysdate from a CONSTRAINT. Therefore I am now attempting to do this using a trigger, but I don't really know how to do this. Here is the sql code used to create the table:
-- PLACEMENT TABLE
DROP TABLE placement;
CREATE TABLE placement
contactId Int,
placementId Int,
position VARCHAR(60),
description CLOB,
lengMonths Int,
salary Number(7,2),
deadline DATE,
startDate DATE,
addrLine1 VARCHAR(120),
postCd VARCHAR(10)
And here is my attempt at creating the trigger that will only allow the deadline and startDate to be entered if they satisfy the following check: (sysdate < deadline/startDate <= sysdate+365)
CREATE OR REPLACE TRIGGER trg_deadline_low BEFORE INSERT OR UPDATE OF deadline ON placement
BEGIN
IF :deadline <= SYSDATE THEN
ROLLBACK;
END IF;
END;
CREATE OR REPLACE TRIGGER trg_deadline_high BEFORE INSERT OR UPDATE OF deadline ON placement
BEGIN
IF :deadline > SYSDATE + 365 THEN
ROLLBACK;
END IF;
END;
If possible, I would like for these triggers to display an error rather than just using ROLLBACK, but I'm not sure how! At the moment, these triggers do not work at all; I get an error message "Warning: Trigger created with compilation errors." when I attempt to create the triggers in the first place.
Can anyone tell me why I am seeing this error when trying to implement the triggers? And if anyone could also improve on my amateur attempt at coding a trigger, then that would be great! Thanks for any help!

Oops!
Nicolas, Thank you for correcting my mistake.

On the contrary, I think that OP want an error instead of rollback : "I would like for these triggers to display an error rather than just using ROLLBACK"Ah, I had misread additionally. Sorry.

HELP NEEDED CREATING VI WITH POTENTIOMETER

Hi Everyone,
I have a DAQ 6009, linear potentiometer and a spring.
I want to measure the displacement of a spring using the linear pot and correspond this displacement into a force by multiplying by spring constant k. (F=-k.x)
F=force, k = spring constant, x = displacment
I need to create a VI that will,
Take voltage readout of potentimeter and correspond it to 0-110mm displacement of spring. ie 0V=0mm, 5V =110mm.
Multiply the displacement mm by k (which is 25).
Record values into excel file and display when stop button is pressed.
Record peak force (amplitude).
When the pot is fully extented it would correspond to 0mm/0V.
Please find attached current Labview VI and linear pot.
As you can see it is multiplying the voltage reading by 25, I want to correspond this voltage to a displacment and then multiply by 25 so I will have output in Newtons.
Thank you for your help,
John

I am fairly new to Labview, so excuse my lack of knowledge at the moment.
I didn't use a custom scale. Can you inform me of what to do?
I multiplied voltage by 20 to correspond it to mm then by k (25) to convert it to a force, is this correct?
I reversed the ground and 5V supply on the 6009 so it will be reading 0 when pot is fully extended?
Below is DAQ Assistant and Block diagram/front panel.
Also my read from measurement file graph is only generating a somewhat straight line instead of an actual waveform??

Help needed creating a linked list program

I have been trying to create a linked list program that takes in a word and its definition and adds the word to a link list followed by the definition. i.e. java - a simple platform-independent object-oriented programming language.
the thing is that of course words must be added and removed from the list. so i am going to use the compareTo method. Basically there a 2 problems
1: some syntax problem which is causing my add and remove method not to be seen from the WordList class
2: Do I HAVE to use the iterator class to go thru the list? I understand how the iterator works but i see no need for it.
I just need to be pointed in the right direction im a little lost.................
your help would be greatly appreciated i've been working on this over a week i dont like linked list..........

generic messageThat's because there is no add(...) method in your Dictionary class: the add(...) method is in your WordList class.
To answer your next question "+how do I add things to my list then?+": Well, you need to create an instance of your WordList class and call the add(...) method on that instance.
Here's an example of instantiating an object and invoking a method on that instance:
Integer i = new Integer(6); // create an instance of Integer
System.out.println(i.toString()); // call it's toString() method and display it on the "stdout"

Help needed creating a Live Poll

I am relatively new to flash. I need to create a website that has only one question on it, and then displays the poll results automatically after a user makes a selection, showing the overall results updated in real time. Can anyone point me in the right direction on where to get started with this. I imagine I will need some php and possibly mysql to make this guy go. Any help would be geatly appreciated.
Scott

in as2, use two different instances of loadvars. one to send variables/values and the other to receive:
var sendLV:LoadVars=new LoadVars();
var receiveLV:LoadVars=new LoadVars();
receiveLV.onData=function(src){
// do whatever
sendLV.var1=xxx
etc
sendLV.sendAndReceive("yourasp.asp",receiveLV,"POST"); // assuming your asp si expecting posted variables.

Help needed creating GUI simulation

Hello,
I have created a 2d image showing a ship on waves. This is done using java2d. I output using JFrame.
I now want to animate it so it moves along the frame size should remain the same but the ship should
appear to move on water... I think time will be involved so the ship moves along the x axis...
please can some one help how to animate this/simulate the ship moving
currently i only have java2d image of a ship and waves..
thanks

Also, this forum is not a site for tutorials as it is asking way too much of a volunteer. The best I can recommend is search here and on google for articles on java animation. You will get better answers and help here with more specific questions.
Another tip: look into the Swing Timer class to help with the animation. You will likely need to use threading as well. If you're not up on this, I suggest the Sun Java Threading tutorials.
