Need Some Info Please

Hi. Im very new to java and no naf all about it....
As part of my course we are going to start programming in Java..
But thats not what I need help on.
As part of a project I'm setting up a Wireless Hotspot....
Is there any way of using some part of Java to to make a secure connection from Server <-> Client.
The reason I ask is that I've been told that java is almost impossable to hack.....
Sorry for my Ignorance on Java....I'm playing chatch up...but will get there...

excuse me a sec....
AH HA HAHA HA HAH AHAH HA
Start at the beginning my friend and let your path be a fruitful one. If you're new to java this the worst possiblt place to start.
You can have secure connections quite easily in Java but learn some basic java before you even think about getting near this stuff. Just have a look at the posts on this site with poor noobs in i upto their neck cus they tried to run before they could walk.

Already gone through troubleshooting guide a zillion times. Thanks.

This worked for me... A little time consuming but once you get rolling it goes GREAT... Thanks....
I got my artwork and saved it to my Desktop
Opened up Microsoft Paint and clicked on "File" and "Open" and found it to get it on the screen to resize it
Clicked "resize" and a box for changing it opened up
Checked the box "Pixels" and "Unchecked maintain aspect ratio"
Set Horizontal for 640 and Vertical for 480
Clicked on "OK" and went back to "File" and did a "Save As" and chose JPEG Picture
It came up "File Already Existed" and clicked "OK" (really did not care about the original artwork I found because wrong size)
Went to iTunes and on the movie right clicked on "Get Info", clicked on "Details", then "Artwork"
Go to the little box on the top left that shows your old artwork and click on it to get the little blue border to appear around it and hit "Delete" to make it gone
Click on "Add Artwork" and find it where you put the one from above on your Desktop and hit "Open" and OK and your new artwork is now there and all good.
Sounds like a lot of steps to follow but after around 5 or so you will fly through it. This worked perfect on my iPhone 6 Plus and I have artwork on my Home Videos now.

Hi! I got movies on my external hard drive that are AVI kind and won't play on my macbook pro? need some help please!!

Hi! I got Movies on my external hard drive that are AVI kind and won't play on my macbook pro? When I start playing the movie a message pops up and says "a required codec is not available". I tried flip4mac, xvid, divx already and still not playing my video. need some help please!! thanks.

Although vlc mentioned above is a much more powerful and better player you could try installing Perian if you insist on using the quicktime player. It may supply the codec it needs.
Not sure why you wouldn't be able to play straight avi files though in quicktime.

Satellite Pro A10 - need some info about RAM upgrade

Dear Fourm members
In regard to the above machine : please can anyone advise :- how many memory slots does it have.
I think it is two but am not sure.
Also what max size memory module can we have in this laptop please.
If it is 2 @ 1gb per module, then we would have a total of 2gb.
Is the hard drive on this machine a standard laptop hard drive. Can I take the small 20gb one out and replace it with a larger one. eg 120 gb etc
Thank you so much for your help.
Ian

On satellite Pro A10 two memory slots are available. Notebook can handle with 1 GB RAM and you can use two compatible PC2100 512MB (PA3164U-1M51) modules.
This old machine uses 2,5 HDD with old IDE connector. I found some info that it was delivered with 20GB, 30GB and 40GB HDDs. I think you can upgrade it with HDD up to 100 GB but just be sure it has the same HDD connector.
If you have more questions you are welcome.
For more info post exact model number please.

HD Workflow - Need Some Clarification Please

Apologies for asking another question so soon, but I need some help with my import/export workflow please.
So I've just upgraded to AE CS4 from 6.5 Pro.
I'm doing a show where I'm using XDCAM EX footage with cgi shots and elements, all comped in AE. The shots will be handed to the editor, who uses FCP, as Quicktime files, I think. This is where I need some help.
I have read and re-read (several times) the 'Color Management Workflow in Adobe After Effects CS4' pdf, specifically the 'High Definition Video Workflow' section. I am using a calibrated monitor (regularly calibrated and checked with a Spyder 3 Elite).
I get setting up the AE project to be colour managed to the HDTV (Rec. 709) working space, and I likewise understand using Interpret Footage to colour manage assets that are imported.
Where I'm falling down is outputting the finished shots to QT movies, specifically on two points: the apparent gamma of the output (as I see it in the QT Player), and the data-rate.
I understand setting the output to have the same profile in the Output Module of the Render Queue. But from there I'm stumped, because the QT outputs don't visually match the AE comp, with almost any codec I try. I understand there are QT codec issues when outputting from AE - I was reading about those the other day when I was hitting the same problem in AE 6.5. When I open the QT movie on the desktop (Windows XP Pro) it's invariably alot lighter, lower contrast. Along with the other issue that the data-rate of the QT output from AE is anything up to 8 times greater than I need.
I tried rendering Animation and PNG movies from AE, then feeding those through the Media Encoder, outputting via H.264 to get an MP4 with the data-rate around 50mbits/sec. That works on that, but again the movie is pretty washed out and low contrast.
I guess this is pretty fundamental stuff, but I've hit a brick wall over what to do. I'd appreciate any advice on the workflow to output the finished comps to hand to the editor, as a movie file, QT or whatever. And obviously knowing that what I see in my AE comp is what he will see on his FCP suite.
Julian.

Thanks for the additional comments and ideas.
In terms of profile, as I mentioned, the intermediates will be going off to the editor (off-site) for editing on his FCP suite. I'll stick to working in the prescribed HDTV (Rec. 709) space, and I've given him all the detail I can of how I'm working, but crucially I haven't stood at his edit-suite to see how the stuff looks.
But, he's no newbie, so I'm hoping it'll be OK.
Blasted shame about the H.264 BluRay not being compatible with QT - I thought I had this whole issue beat until that came along. It's not a matter of disk space here, but the editor is mithering that the intermediates we are testing, in either PNG, or Animation, and a couple of others, are choking his playback.
I'm not sure what to say about that, other than to go down this road of trying to squish these intermediates as low as possible without wrecking the look, hence finding that the DNxHD is providing the best solution. If it had been a SD project, I might well have tried the native H.264, even over our normal PNG workflow.
So what will play the native H.264 BluRay compressed output?
Julian.

New Member wanting to buy but needs some info..

Hello all, I am new to this forum.
I have found this forum in the search of information regarding these Wind Top pc's.
Information is fairly thin on the net so I thought it best to join this forum and ask my questions here where I am sure I will get acurate answers.
I have searched the threads here in but still need some clarification.
My scenario is as follows:
I want to use one of these AIO's mainly as a music and music video jukebox.
Tv tuner, either built in or usb external would be good also.
Sound output is to a set of active Audioengine A5 2.0 speakers.
Ive been checking out a few other brands like:
Asus, Shuttle, HP, Lenovo and Gateway, though I like the look of the MSI ones the best.
16 inch is realistically too small, 20 inch is just about right and 22 inch upwards may be a little big and probably a little to much like a fully fledged pc, which may be a little much for what I need?
It will be placed in my Kitchen/Dining/Sitting room. Size is 8m x 6m.
I dont really want to spend a fortune, maybe below a $1000 if possibe but definately not to much above $1000. I am in Australia, Tasmania actually and viewing/demoing is fairly non existant.
The MSI 2020 or 2220 etc is probably at the top of my list.
It looks similar to a large picture/photo frame as apposed to a fully fledged computer.
I have attached my Audioengine A5's to my dell 15" laptop, T6400 or 2.0 gig core 2 cpu, 3 gig ram and Radeon HD4570 gfx.
Installed 80 gig of music and when starting/browsing windows media center for music, it does OK but I can see its not as quick as I would like it to be.
Therefore what worries me is trying to work out how one of these lower specked MSI wind top touchscreens will perform.
Can anyone please share their thoughts or experience especially regarding the browsing and playing of a music mp3 collection of reasonable size eg 80 gig etc.
Thanks in advance

It's probably a good idea to check out reviews as that will give a good idea of whether it meets your needs. I don't own a Wind Top so can't comment on what it's like to use.
MSI Wind Top AE2220 review: http://www.theinquirer.net/inquirer/review/1594404/msi-wind-top-ae2220
You'll obviously want better performance than your laptop, which would rule out the Wind Top AE2020, since that has an Pentium T4500 Dual-Core processor, which is slower than the Core 2 Duo T6400. The Wind Top AE2220 would be the better choice of the two since it can come with the Core 2 Duo T6600 processor.

I Need some info about interfacing the PC or laptop to Spectrum analyzer using Labview

we need to control the spectrum analyzer using an interface that will be developed using Labview .
Spectrum analyzer will be connected to tha PC using RS 232C and the waveform observed will be seen in the PC interface of spectrum analyzer.
Pls send some info regarding dis.

Using a spectrum analyzer with LabVIEW is a pretty common application, my first program 15 years ago did this. What we need to know to help you though is what model spectrum analyzer are you planning on using? Most of the ones I'm familiar with use the GPIB interface rather than RS232, but that isn't a major issue, the spectrum analyzers command set is the important one. There are a lot of LabVIEW drivers available for a larger number of analyzers, here on the National Instruments' site. Although most use the GPIB interface (or ethernet), they can be used as a starting point to develop an RS232 driver if one isn't available, assuming that there is a driver for the model that you have, or a closely related one (manufacturers frequently use similar command sets within a model type).
So, what type analyzer are you using, and what types of things are you planning on doing with it?

New Builder needs some info K9A Plat. RAID Array help

This is a new build AMD 64x2 6000+, K9A platinum, Lite On DVD Re Writeable SATA, 2x74Gig WD Raptors in Raid 0, Asus X1950 pro Thermaltake 700 W PSU Crossfire cert.
BIOS registered my drives, Built array PC Rebooted, Installing Win XP pro Hit F6 install drivers, Format drives, Then before Install It says that :setup cannot copy the file ahcix86.inf.
If I skip it, it will install XP but when I try to boot from the hard drive It starts to load XP but crashes to the blue screen of death
*** Stop: 0x0000007BC ( 0xF78A2524, 0xC0000034, 0x00000000, 0x00000000)
Has anyone got this error string?
First RAID array I would very much appreciate any help given.

Hi!
Looking at some info on Google and Microsoft site, I cannot find the BC error code, only the error code ending with B. It indicates an error with the boot device. It can be caused by several things.
Check that you are using the correct device drivers to install Windows
Also, check the installation CD. It could be that the disk was damaged and that you are missing a crucial file because of that
You can also try installing Windows again and choose to recover the previous installation.
If this all does not help, try installing Windows on a single HDD (no raid) to see if that will work.

Need some info on BI CONT 7.x

Hi,
I need some clarification on BI Content ADD ON 7.x.
Though new versions are getting released day by day with good new add on modules, but do we have BI Content which has complete DTP's and Transformations for Logistics and FI module.
I hope it might be confusing, i will come some other way around.
with bi content 3.5 whenever we activate a cube/ODS using business content in RSA1 by taking in dataflow before it will activate cube/ods, update rules/infosource etc.., in the same way if i activate LO or FI modules cubes or DSO using BI content 7.x can i get Transformation,DTP's get activated.
for your information till now i have not used Bi content 7.x.
I could gain some knowledge from your end.
thanks
Prashanth.

The business content is still not in 7.0 dataflow. So you need to install the 3.x objects and migrate them to 7.0 And as far as the 7.x infosources, if you want u may install them and use for the transformations (while converting the transfer rules). Anyway the system wil prompt you to use a existing 7.0 infsource or conver the existing 3.x infosource. And infosource is not mandatory as of 7.0 dataflow.
Thanks.

I need some info about the Document Class.

Hi,
I need some information about the Document Class, can anybody
tell me where I can find it.
thanks

Emad Zedan,
> I need some information about the Document Class, can
> anybody tell me where I can find it.
The concept of the document class was introduced in Flash
CS3. What it
does is allow you to optionally associate a custom AS3 class
with your FLA
in the Flash authoring tool. Your document class effectively
*becomes* the
main timeline. This is your chance to influence the
underlying behavior of
the MovieClip or Sprite instance that serves as the
foundation for your SWF.
If you don't associate a custom document class with your
FLA, the FLA is
associated automatically with a default document class called
MainTimeline,
which extends MovieClip.

Need some info on general question

Hello everybody!
This question for those who already works as a Java professional. I just don't have a clear picture of how can you apply java programming language in real working environment, in theory I can imagine, but I need a solid understanding so that I would spend all the time moving in right direction. Do they use Java for writing some applications for some, let's say, financial institutions. I can write simple application which will connect to some RDBMS (SQLServer,Oracle, whatever you have) and perform extracting, changing, deleting information, but I can do all this stuff only on my user computer, I am just college student. How do you implement this in real environment, do you have first to install Java Runtime Environment on all user computers and install those java applications which will be working with database? What about middle-tier concept, what this all about? I happend to have interview in one company but I failed to answer on middle-tier topic. As I understand it's better to change some procedure in one place than changing apps on all user computers, how you deal whith this, this is so far not clear for me. I have never seen how users launch their apps in financial institutions (exe. files - popular question on this forum), how does this system works, or may be they use for this purpose different language like C++. What about internet, they say java was created whith internet in mind... Oh my god, I have so many questions on how you can use Java in real world, not just for fun. Hope somebody can explain it to me in plain English.
Thanks in advance.

Here is a real world example (its a project I've been working on for about a year).
Its a 3-tier client server system. This means there are 3 parts of the system:
1. SQL Server database on a remote server
2. Middleware java application running on the server
3. psion netBook clients (handheld devices) running a Java application
The actual system itself is used for remotely capturing dental information on the netBooks. At the end of the day the user can dial-up to the server where the database resides and update the database with info captured on the netBook. The user can also download a group of patients from the server to the netBook client.
The purpose of having a middle tier (or middleware), is so that any server-side changes will not impact on the client side, and vice versa (at least thats always been my understanding).
To create this architecture I used the JDBC API (for database processing, middle tier), and the RMI API (for networking, middle tier and client tier). Alternatively I could have used CORBA instead of RMI.
I beleive (although I'm no expert on this), that servlets can be used to create a similar kind of thing through a web interface (i.e. a database on the web server can be updated through a web page). Hopefully someone can confirm this for you.
And of course there are applets, that are simply java appications running on a web browser.
I would imagine that the majority of industry work done in Java is with client server apps either with servlets (web) or a backend on a server somewhere.
If anyone would like to correct me please do...think I've got most of this right.
