Robotic programming and others

hello friends,
P lease, can someone give me a hint on the following :
1. resources including appropriate softwares, code, classes, materials
i need to write a java program that can send commands(or signals)
via an infra-red(as in a TV remote control) or via laser or normal wires,
to a machine or robot. for instance asking a machine to start, stop etc.
or asking a robot to move, fly, land etc. how can
i achieve this. your help is most welcomed thank you.
2. i have a java program, which has a GUI that covers the entire screen including
the status bar(just like in screen savers). But while it is visible, or being used
and a user clicks CTRL + ALT + DELETE, in order to shut down or activate the task manager
to enable him terminate the program, he achieves this successfully. But i don't want him
to be able to do so. I want the java program to be the first to intercept or trap the
CTRL + ALT + DELETE , and not the Operating System. I'm using windows2000 and XP.
What code can i add to my java program to enable it trap this instead of the OS. The function to
achieve this should only function while my program is running. Moreso, when it traps the key events
it should request for a password to terminate the program, which if not correct, the program remains.
3. can i deactivate the taskbar while my java program is running or prevent the taskbar or the programs
menu from comming up when the user presses the window icon on the keyboard. can i achieve any of
these with java. If yes, please how can i do these.
4. any idea of a site where i can learn stuff on robotic programming with java and microprocessor
programming with java.
5. Please, sample codes will be well appreciated.
Thank you in advance for your kind help.

hello,
in my question on this topic i got the following reply:
1) In a previous Java Tech Days conference (2002), Simon Ritter from Sun shown us a small demo using Java-controlled robots (actually a Lego Mindstorms one, see http://lejos.sourceforge.net/ ). Maybe you could try to contact him in a Java Tech Days conference near you, or use the e-mail (simon dot ritter at sun dot com)
2) Ctrl+Alt+Del is not trappable. You can use Windows policies to keep the user logged in a "kiosk mode".
3) Same as 2)
4) Same as 1)
5) Same as 1)
please, how use Windows policies to keep the user logged in a "kiosk mode in java. codes will be appreciated.

When I get art work from older illustrator programs and other programs the colors don't print the same as they did about 2 months ago. Big issue for me! How do I cange this or fix it?

Things were going fine until about a month or so ago, now when I take files from older illustrator programs or other programs that ran fine with illustrator before, the colors change. This is a BIG problem for me right now! I tried the on line help thing and I was afraid to erase the files that it asked me to erase because I may want it back the way it now is some day and because I don't have the files from the older program... PLS help! Have tryed to call and am waiting for a chat to open,...

gaskins,
You may have different Color Settings, and if you use Pantone you should be aware that the whole interpretation has changed (a number of times, most radically recently).
If you say more, more can be said.

How to find which programs (and other objects) use the field LGORT

Hi, Im an Abap freshman, and I have been asked to search all programs and objects that use the field LGORT (Storage Location), regardless of what table it is in.
Is it possible to do it using the "Where-Used List"?
This will be important since a new Storage Location will be created for MM, and we have to assure that no other programs that reference to it will be affected.
I would appreciate any help. Thanks!!

Hi George,
Go to transaction SE11, choose radiobutton Data Element then enter the name LGORT. Now using the where-used-list in the toolbar, choose programs checkbox in the subsequent dialog and press enter. It should show all programs using the field LGORT irrespective of table name.
Hope this helps.
Cheers,
Sougata.

Properly removing programs and other files

I recently tried to install World of Warcraft on my macbook. After I realized that my computer was just a little too slow to run it properly I tried to erase it. Now my macbook is telling me that my hard drive is almost full and I'm convinced that I didn't remove World of Warcraft properly. How do I check if I removed it or not and if I didn't how do I properly remove it and other files for future reference?

Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper
Automaton
Hazel
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

OO programing and other help......

I got the following done. It is very nearly finished. Apart from a few error. ( Which i can't find out why so if you figure it out please be so kind to tell me. )
I think you could see my idea and what i intend to do in this program. But it is my first long program so if i did something abnormal and idea how to improve it please tell me as well.
Something concern me is that it is not very OO. And the only reason i spend so much time trying to learn Java is because i can't get my head around OO programing. Although finally i manged to find a book to make me understand it. But doing it myself and using OO in pratice is much harder than i thought. ( As you can see in my code is very procedual ). So any comment on that issue is well come.

CC (2014) Photo Program and other CS6 apps - Updates for CS6 to CC (2014)?

I have the CS6 Design & Web Premium apps installed, plus the Creative Cloud Photo Program option (PS and LR).
With the new CC (2014) release today I'm being offered CC (2014) updates for all the CS6 programs that I have that aren't in the Photo Program (i.e. Dreamweaver, Illustrator, InDesign, etc). Surely this isn't right. Shouldn't it be asking if I want to Install or Try them rather than providing an update?
If I go ahead and update will it start charging me more? Its a bit confusing!

I installed all the updates, including the CC 2014 programs. I am not being charged for them. However, they are not updates to the other programs. I now have 2 versions of all my CS6 programs installed on my computer. The CC 2014 programs are now default, for some reason, and when I open them they ask me if I want to start a free trial or if I want to put in a license code. My CS6 code doesn't work, obviously, but I tried anyway. I'm a little annoyed that this was offered to me like it was an update for my programs, even though it wasn't. And if I uninstall them, I am afraid that it is going to tell me that I have "updates" and try to install these programs again.

How do I go back to 3.6 from 4.0. Having problems with Wikipedia and can't work with a shorter display [half screen] good with 4.0. McAffee, Norton and other programs aren't supported on 4.0

I need to go back to 3.6 from 4.0 Because:
1. Norton, some Mcaffee, and other needed programs aren't supported yet.
2. Can't downsize 4.0 to fit properly on a half screen, when using a text editor on one half and 4.0 display on the other half. I have to go to a full screen to do somethings, and then back to half screen after. Things aren't easy anymore.
3. When moving references and extras from Wikipedia to my PC, the reference numbers and other generated items are missing on my PC. Never with 3.6
Things are not easy going with 4.0!!!!!!!

How many computers can I install Photoshop (and other adobe programs on)?

Hi. I was wondering how many computers I can install a purchased version of Photoshop onto (or other Adobe products)? Can I install one copy onto two systems I own, eg: my desktop and laptop? Or only one total? Can I buy additional licenses for that version if needed? What about with older products Eg: Photoshop 4 Extended, or another?
Thank you.

I'll reply to my own post witht his for anyone else who wants it. i jsut chedked out Photoshop 5's system requirem
ents and just found out yes there are two licenses or more - if you pay.
http://www.adobe.com/products/activation/
Anyone want to add anything: Please do.
I would like to say that being able to add software onto 2 systems, especially software for productivity and fun, is highly important. This is something Adobe needs to keep doing and a lot of other companies too. Plus it is something some companies need to look into if they can set up the system right. This is one reason I am planning on buying one companies software for music production over the other (which also requires the usb key/lock or company #2's product doesn't work). It is a good selling point for someone like me with a desktop and laptop, cost is a factor with double programs.

How to run different programs and use their output in other programs

Dear java members,
I am trying to figure out how to get data from a file, database, or program and use that information in another
program. Can you help please?
I have looked through several texts and while the information is there somewhere I have not found the specific
capabilities or examples that explain how to do this.
I want to learn how to do this with objects.
The specific applications I am working with are the GIS (Geographic Information System) suite of ESRI products
such as ArcInfo and ArcView.
I am working with simulators for hydrologeology (ground water) and other geophysical phenomenae. Programs for
decisions and assessment of probability such as found in geostatistical analyses packages. Drawing programs
and data manipulation programs such as spreadsheets in windows and scripting languages found in most Unix
packages.
I want to be proprietary platform free! I want to be accessing apps and or data wherever they are and in
whichever form they are in or best used.
Web techniques and protocols are where I think most of my effort will be focused.
One of the mediums (media) that I expect to use a lot is XML.
If I can find a simplified (generalized) explanation how this is done and how the parts fit together through and or
with objects. If I can find references to texts and examples I will be very appreciative and very much less
confused.
I am interested in using the Java programming language.
Thank you
ctavares1

Hello ctavares1,
I am not quite sure that I understand what you are trying to do. The programs that you mention: ArcInfo and ArcView, are they stand alone, native, platform dependent applications? Or are they written in Java? It sounds like there are stand alone, native, platform dependent applications, that write their output to either a file or a database.
The other piece that is puzzling me is: Do you intend to write an Applet or a Java Application? This is important because Java places several restrictions on what an Applet can do.
There is also the question of how the data is produced. Is it produced all at once in batch or is it produced a little at a time in real time?
These and other questions will need to be answered before you can begin designing your application. There are many tutorials dealing with opening a file or database and manipulating that data from an Applet or a Java Application, but it is a different matter all together getting data from an application.
Here are a few tutorials on File I/O and JDBC:

Even if i do not open firefox i can be running another program and firefox repeatedly minimizes my other program and opens up search tabs. how do i get it to stop

i play an online game called perfect world. for some reason i can be in the middle of a game and firefox will minimize my game and open up tabs even if i am not doing anything with firefox. how can i fix this. it is really getting annoying

Try a clean reinstall and delete the Firefox program folder and desktop shortcut before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 23.0: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Large applications - Labview and other programming languages

Hello Labview Users,
as the forum saw this very interesting thread about large applications programmed in Labview
(see: http://sine.ni.com/niforum/niforum?requireLogin=False&forumDU=http://forums.ni.com/ni/board/message?... ) I would like to ask the community about their experiences with Labview applications in combination with other programming languages.
In advance: I have several years of experience in programming Labview applications starting from quick-and-dirty solutions which had to run within few hours and complex test solutions. I saw Labview growing and becoming better with the released versions and lot of things I missed in former times got implemented in the meantime. Actually I have to develop a complexe ATE solution with numerous equipment to control and numerous data to be captured and archived. Despite the Verison 8 I still feel still some drawbacks of the LV concept which let me hestitate to setup the solution completly in Labview:
1) It is alway hard to re-use code of complex applications since it is not possible to do some kind of global search an replace of functions
variables etc. It nearly impossible to re-use approved code structures (e.g a state machine) if the "inner part" is changing more the a little bit.
2) If the application requires a certain flexibility (e.g. exchangeable test equipment of varying vendors) this is hard to implement since you have to define a lot of parameters through your hierarchy if you dont want use global variables which slow down your application and hide
the code functionality.
3) Despite modern PCs the look and feel of LV applications appears somewhat slow compared to other applications. For complex user interfaces the polling methode generates a lot of complex code. (I dont have expierence with the event-structure).
Now my questions:
Do you have experience of implemention of complex solutions dividingthe code modules using Labview and other languages? Which other
languages did you use? Why did you use these languages (speed, flexibility of text based code, available library functions)? Did you found out this to improve your development time and code maintainibility?
(I concider a solution where I do the single tests with Labview-VIs but delegate all the test sequencing and data collection stuff written in PERL which allows really very compact code)
I'm curious what your experiences are.
rainercats

Given that you're asking these questions in a forum for LabVIEW users the opinions given are going to be somewhat slanted towards the general like of LabVIEW. I've been working with LabVIEW for a long time, ever since 2.something on a Mac. I've written numerous large-scale applications as well as "mundane" instrument drivers. As you've noted you're experienced with LabVIEW, so you know some of its strengths and weaknesses.
To address your specific questions:
(1) Yes, that has always been a limitation in LabVIEW, but I don't believe it is an overriding one to choose C over LabVIEW. Putnam provided one workaround for the search and replace of VIs. Once you've programmed in LabVIEW long enough you get used to doing it this way. Is it clumsy? Yes. As for the re-use of code structures, that's not entirely true. You can create a "template" VI (a regular VI, not a .vit) that contains the code you want to re-use and place in your palette with the "Merge VI" option set. That way you can select it from your functions palette, plop it down on your diagram, and you get the "template" VI's diagram placed right into your new VI.
(2) This is not something that is specific to LabVIEW, as this exists with any programming language. It's not the language that limits you here, it's how you've designed your code. In a language like C++ you would go with classes. You can do the same thing in LabVIEW. IVI is another option (though not preferred by me).
(3) As Putnam mentioned, you should be using the event structure.
Other thoughts:
The biggest strength I see with LabVIEW is that each VI is a miniature program, which allows development and debugging of functions a snap. With a language like C you have to write another program to call that function in order to debug it. The biggest weakness? I would say user interface. Yes, even with the event structure. Don't get me wrong, the event structure has vastly improved the way user interfaces and event handling in general are done with LabVIEW, but it simply doesn't hold muster to a program written in C or VB. ActiveX anyone? LabVIEW still doesn't do ActiveX properly in terms of actually getting the controls to work. Programming ActiveX controls is just plain aggravating what with all the property nodes taking up so much diagram space.
It certainly makes sense to use the best tools available to you to get the job done. In my recent projects I had to write software to run automated tests on some products my company made. The test modules were written in LabVIEW. The tests executive was a proprietary engine driven by a SQL Server database. I had to write a "wrapper" DLL that interfaced between the LabVIEW code and the executive since the executive hadn't been designed to call LabVIEW DLLs directly. This allowed us to use LabVIEW as the preferred language for developing the test modules and let the guys who were fiddling with the test executive do their bit. Of course, TestStand's premise is basically that.

How to close Internet Explorer and other programs running on Windows?

In order for Flash Player to be installed or updated, any programs that use Flash Player must be closed. This includes Internet Explorer or other browsers, instant messengers, Skype, etc.
These programs may be running in the background, not as visible windows, but need to be closed anyway.
To close such programs use the Windows Task Manager. To start Task Manager, take any of the following actions:
Press CTRL+ALT+DELETE, and then click Task Manager.
Press CTRL+SHIFT+ESC.
Right-click an empty area of the taskbar, and then click Task Manager.
Once the Task Manager is running, select the Processes tab. On older Windows version you may need to click on the Process Name or Image Name header to sort the process names.
Now right-click on every process that the Flash Player installer needs to close (e.g. iexplore.exe), then select End Process.
It would be desirable if the Flash Player installer could perform that action by itself; I have therefore created an enhancement request. If you were affected by this problem, please head over to the Bugbase and vote for this request: https://bugbase.adobe.com/index.cfm?event=bug&id=3548136
