How can I use a iteration control to compare with array?

Dear All
I have done a program and I need to test me program...but I seem to have to problem...I don't know how to use a iteration ( a for loop ) to test my program...
My test code is written like this...
public class ClockWatchDemo
public static void main(String[]args)
TimePiece[] tpList = new TimePiece[3];
tpList[0] = new Watch(200, "Vintage", "Men");
tpList[1] = new Clock(400, "Classic", 70);
tpList[2] = new Clock(300, "Futuristic", 45);
for(int i=0; i<3; i++)
if( i == tpList[0] ) // how can I do to compare my temp integer with the array number?
System.out.println(tpList[0].toString() + "\n");
else
return "";
Please advise

Thank you for your help but how can i compare my temp int i to the tpList array?
I wanted to do something like this
if( i == tpList)
System.out.println(tpList[i].toString() + "\n");
but I will get prompt to inform me that
if( i == tpList[i])
incomparable types : int and TimePiece
Please advise.
Thank you

Can I use ARD to control my mac with Back to my Mac service?
The with Back to my Mac service on you see your mac in the Shared column, hit Share Screen & your good - on ARD I don't see my remote Mac listed anywhere in that program.
Thanks

ARD, to the best of my knowledge, does not work via Back To My Mac. Certainly it's not an direct or obvious feature, though I can't say that there might not be a workaround I've not heard of.

How can I use the built-in Isight camera with an external camera (usb/firewire) at the same time?

How can I use the built-in Isight camera and an external video camera at the same time?
I'm wanting to stream over Oovoo/Skype/etc. using 2 cameras.
Thanks

Simple question with a not so simple answer.
(a) If you mean that you want to run multiple apps simultaneously using a different camera with each app, you may encounter computing power limitations. Digital video is processor intensive. The only way to know if your Mac can do this it to try it. If the video does not work together but each app works when it it the only app running, you are likely overloading your Mac's ability to process and/or move all the required data in your data bus. You can get a better indication of whether this is the case by watching your Activity Monitor utility while running the apps you want to use.
(b) If you mean that you want to have more than one compatible camera connected to your Mac simultaneously for ease of changing between video sources, some, but not necessarily all, apps you are using to operate your camera(s) allow you to select between your cameras.
How you select among connected cameras depends on which application you are using. Here is how camera selection works in a few examples:
(1) For iChat, you can choose which iSight you use in the "Camera:" choices bar in iChat > Preferences... > Audio/Video that appears when more than one compatible camera is connected. Although your camera choices will be different, the choices bar will look something similar to the Preferences settings shown here:
If you cannot see the "Camera" choices bar, your Mac is recognizing only one (or none) of your cameras. In that case, consider the suggestions fromhttp://support.apple.com/kb/HT2090 for iSight problems or refer to your other camera's documentation for help.
This particular choices bar solution applies ONLY to iChat. Most other applications also have settings that allow you to choose which camera to use. However, they do not all work the same way.
(2) For instance, iMovie HD's camera choice is NOT set via Preferences. When you have more than one compatible camera connected, iMovie6 HD uses a drop-down menu choice something like this (depending on which version of iMovie you use):
Note: Because I had no built-in iSight connected when I made this example, and because my external iSight was not connected, the drop-down menu showed only "Time Lapse." Because your Mac has a built-in iSight, your built-in iSight would show in the drop-down menu even when no other camera is connected. Connecting an additional Mac compatible webcam should allow you to choose either camera.
Other iMovie versions work slightly differently.
iMovie 9 (from iLife '11) uses a different camera choice button shown in this article:
http://docs.info.apple.com/article.html?path=iMovie/9.0/en/mov39f84285.html
iMovie 8 (from iLife '09) is slightly different as explained in this article:
http://docs.info.apple.com/article.html?path=iMovie/8.0/en/10172.html
In general, you can use your Mac's help for the application in use to find out how to select among more than one connected camera.
(3) Photo Booth in Snow Leopard 10.6.x and later uses the Photo Booth > Camera menu command to select which camera to use.
Note for readers with older Mac OS X: The previous version of Photo Booth that came with Tiger (10.4.x) is such a simple, basic app that it offers no menu selectable choice. Unless your built-in iSight is already occupied as the camera being used by some open application before you launch Photo Booth, Photo Booth will use ONLY your built-in iSight.
However, you can use the trick from ¶ 4 of http://docs.info.apple.com/article.html?artnum=302781 to let Photo Booth use an external camera.
(If you have an external Firewire camera connected, it may be used in preference to any USB webcam. If that is a problem for you, merely disconnect the problem Firewire device.)
(4) For FaceTime, launch the app and click the Video menu item.
If your Mac recognizes more than one connected compatible camera, a "Camera" section listing the cameras from which you can choose will appear there. Clicking on the desired camera name will let you select the one you want as shown in this image from my Mac Pro and LED Cinema Display:
If your Mac recognizes only one compatible camera, the "Camera" section will not appear in the Video menu, but FaceTime will automatically use the connected camera that is recognized by OS X.
(5) I do not use Skype oir Oovoo. For those or other apps, see Help for each app for info on how to select your desired camera.

No ISA slot available in PC. How can I use PCI-85 Modbus Plus card with Lookout?

My application is to communicate with two Modicon PLCs using Modicon's ModBus Plus (PCI based PCI-85) network card inside my PC, and using Lookout as an SCADA software. Since there is no ISA slot available in new PCs, I can not use Modicon's ISA-85 Modbus Plus networc card. But Lookout does not support PCI based PCI-85 card, how can I use PCI-85 card then, with Lookout? Why doesn't Lookout support it? I asked the following question from from the Modicon's representative about it:
If I purchase Modbus Plus Driver Suite CD (SWMXDS001, 05, or 10 etc),will I be able to use Lookout SCADA software (by the way, it supports standard MB+ prtocol) for my application? If yes, can I use any version of an
y of the ISA, PCI, or PCMCIA based MB+ card?
His answer was:
The Modbus Plus Driver Suite will talk to any version of card, PCMCIA, ISA, and PCI. The question now is will the SCADA package you are
planning on using be able to talk to the Modbus Plus Driver Suite? You must contact National Instruments and ask them if they support Modbus Plus, and if
they used the MB+ system developement kit to develop their product. Or if they wrote their own MB+ drivers, do they work with Modicon hardware?

Hi,
currently Lookout does not support the PCI-85 card. The only card supported for Modbus Plus is SA-85. Please see for further information:
Where can I Find Drivers for Communicating to PLCs, RTUs, and Other Industrial Hardware?

How can I use javascript in a Text Area with HTML editor??

My question is... how can I use javascript in Text Area with HTML editor??
I can use javascript functions that change the content of Text Areas but i can´t if i try in text area with html editor....
I need to limit number of characters in a text area with html editor and i can´t.
could anybody help me please?

I have been experiencing similar problems with the HTML Editor and have managed to find an answer that should start to answer some of my questions. The Apex HTML Editor Standard is actually an HTML editor called FCKeditor. The FCKeditor has a Javascript API that can be found at http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/JavaScript_API. Unfortuately this doesn't seem to give the whole answer and I found more at http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:49607.
I needed to get the text entered within my html editor standard (e.g. P1_MYTEXT) and use it within my javascript function. I did this by using the following script
<script language="JavaScript" type="text/javascript">
function showtext(){
var oEditor = FCKeditorAPI.GetInstance('P1_MYTEXT');
var editortext = escape(oEditor.GetXHTML(oEditor.FormatOutput));
alert(editortext);
</script>
Hope this helps.

HT1918 how can i use a itunes card for payment with netflix?

how can i use itunes card for payment for netflix?

Sorry guy, but I think you are out of luck on that one- maybe someday if Apple gets Netflix under an exclusive contract.. But for now Netflix is its own entity, therefore your account with Netflix is not affiliated with your iTunes account and you have to subscribe and pay for Netflix via credit or debit card.

How can I use LabView to control Altera Scripting

Hi
I have kind of run into a stone wall. I am building a production test executive based on LabView. Part of this process includes loading an FPGA image on to a CFI flash that is in the JTAG chain. I am trying to make so that the production operators don't have to open a second application, select the right FPGA and Flash navigate to the file then load it, then go back to LabView and run the rest of the tests.
Altera has a command line interface that will let me load .cdf file. The problem is that nowhere in Altera’s documentation does it show me how to first load the “Parallel Flash Loader IP” into the FPGA. The flash loader acts as a temporary bridge between the JTAG input and the CFI Flash. I have looked on Altera’s Forums and have had an open ticket with Altera’s support engineers for more than a week.
I can’t be the first person to want to do this; I am hoping someone here has done it before. I would really rather not try to use the activeX controls to manipulate the windows based program.
Any suggestions would be greatly appreciated (Note I am not trying to put LV code on the FPGA/Flash just use LV to control the process)
Thanks in advance
Below is the error message and the script I am using. It almost works just missing the flash loader IP

Hi Eric,
I got it figured out today, basically you have to load the Parallel Flash Loader first into FPGA ram. It is a special .sof file (pfl_epXXXX.sof) based on your FPGA. Code is actually pretty straight forward, using the Sys Exec VI. Use the windows based programmer to generate the .cdf file that identifies your FPGA, attached Flash and .pof file .
Syntax was odd going into Sys Exec. Note the extra "C" in in front of the "quartus_prm.exe" I have no idea why that was needed, but I was getting an error until I just happened to put it in there (Blind Luck :-))
I used a 2 element array going into a four loop
cmd /cquartus_pgm.exe -c USB-BLASTER -m JTAG -o P;pfl_epXXXX.sof
cmd /cquartus_pgm.exe -c USB-BLASTER -m JTAG S_FPGA.cdf
Defining the working director C:\altera\12.1sp1\qprogrammer\bin
And added match string with "Successfully performed operation" on the output in the loop to make sure everything loaded correctly then adding the array to give me a overall P/F
To anyone doing this same thing Altera's documentation is poor to say the least. It took most of a week to figure this out Not allowed to upload code, so anyone wanting details just post here and I will try to help. This was painful, with lots of lessons learned.
Thanks for the interest though
Best regards John
