System Programming

While working in VB.Net it is possible to do System programming such as,By the Click of Button,System Start Menu or TaskBar becomes Un-Visible.Can we do such type of System Programming in Java.

Yes, using JNI.
You shouldn't hide task bars and such, however, people use them.

System programming in Java

Hai!!!
Actully I'm working in Automatic distinction between the system progam & application programs. Is there any samples/source code of the system programs available in java???is it possible to distiguish between the system program & Application program by seeing the code??
Cheers!!!

Just curious what is it system programming in java? Can't recall any example...

System programing using Java

What java class library that i can use for system programing?

Do you mean device drivers and the likes? Java isn't the language for that. You can always interface Java with C and there's also the Micro Edition of Java. It depends on your situation if Java is useful.

Embedded system programming in java

I want to know how to do embedded system programming in java.
can anyone give some sample programs and tell me nice book for embedded programming in java

First take a look at Embedded Server forum (http://forum.java.sun.com/forum.jsp?forum=46) and/or OSGi (http://www.osgi.org)

Related to System Programs

Hi Experts,
                  As per OSS notes i should not use CK40N transaction for batch input program. but i can use ck41 or ck42 .However ck41 or ck42 doesnt have all features like given below(6 points), as CK40N Does.
In my requirement , data is not flat file but i will get data related to
companycode,procuremnt type,material type,plant from some tables and will
store in some internal table.
The requirement must be done with 6 steps as follows by using CK40N transaction and system programs related to CK40N shown below.
1. Selection List                -      saprck60
2. Structure Explosion       -      saprck62
3.Costing                          -      saprck10
4.Analysis                        -       rkkbcal2
5.Marking                         -      saprck23
6.Release                         -      saprck23
Now alternative is to develop report program which uses System programs for batch processing by using submit keyword since we cannot use BDC's.
I prepared BDC data for ck40n transactions,so my question is how can we pass batch input data as parameters to the system programs, so that set of records
are processed by using system programs.
Please give some idea to do this.
points will be rewarded for helpful answers.
please reply me if anything is not clear

You can use submit statement to call and pass parameters.
Thanks,

Systems programming in Java

Is it possible to write system programs in java language? where can i find examples?

like writing device drivers or interacting with hardware i.e. ports input/output just like in 'C'..
If it is possible to write device drivers in java.....then we need not to write drivers for Windows, Solaris and linux separately. Just write device driver once and run it anywhere.. i don't know it is feasible or not.

System Programming thru Java

Dear friends,
can we do System programming like creating device drivers throgh Java.
If any one has idea or related programs Please send to [email protected]
Please let me know about it.
i will be thankful to you.
Else i will have learn C or C++ for that.
thanking you...
Regards....

can we do System programming like creating device drivers throgh Java.No, you cannot do that. The only way to get through to the system-specific parts of the computer would be through JNI... and JNI involves programming in other languages.

System programming with java

hi,
i was trying to fetch system related data, like processor usage, through java .. but i couldn't .. i couldn't find any API for the purpose..
finally used some shellscripting...
is there any API for these purpose?
If there are no such APIs then how java.io works?
how it interact with hardware? how it read input from IO devices?

If there are no such APIs then how java.io works?
how it interact with hardware? how it read inputfrom IO devices?
can somebody answer these?Java technology includes an abstraction layer called the Java Virtual Machine. This JVM isolates all system dependencies. Once a JVM exists for a platform, pure Java programs (in bytecode form) will run on that platform.

In 4.5b system, program temporarily buffered; short dump when changing

Hi,
I have a program needs to be activated in 4.5B system.. when I clicked on Change button it is displaying options: -
a) get temporary version
b) get from database and keep temporary
c) get from database and delete temporary
I tried all the 3 options... and try to change the program and activate it.. It is going to short dump.
Could someone tell what needs to be done..to activate the program and delete the temporary version.
Regards,
HK

Hi,
Thats the real problem . Try this way which i used previously. dont know how effective in 4.5B
1) In the SE38 screen, give the program name. in the menu list,
Utilities ->Versions->Versions Management
2) Try compare the latest with last version. Note down if there are any changes. If not much, you can select the previous version and press Retrieve button ( or CTRL + F5 )
Then try enter the program again. It will be in previous version. then you can activate it
If still this is not working, the practical way is to copy the program, save in local system. Delete the program and create a new one

Re: E540 bios update to 2.17 fails, the system program file was not found

Unfortunately all versions of the BIOS available from Lenovo's site have a bug that doesn't play well with linux. The workaround is to turn OFF USB 3.0 in the BIOS settings. (You can still use the USB ports, just not as USB 3.0.)
Here's a posting with more links if you would like to learn more.
As for updating the BIOS, maybe one could get the updater to work using FreeDOS bootable image, or more likely a linux image with WINE on it... ?
On my new E540 I "cheated" by keeping Windows 7 cluttering up my hard drive for awhile. I have booted Windows only twice, and I NEVER let it connect to the Internet, but I downloaded the .exe version of the BIOS updater and ran it from a USB stick. (It runs as a Windows software installer, which is odd to me.)

I bought this laptop without any system and now the Bootable CD fails to update terribly buggy BIOS. Well done Lenovo. Could be my last Lenovo comp
@conwaytwt How could FreeDOS be used for updating BIOS? I don't think wine will work.
By the way, I tried extracting bios files from the .exe according to different advice in http://www.thinkwiki.org/wiki/BIOS_Upgrade but they failed.
@joonsar, I made that comment without thinking too much ... I have other (older) systems where the BIOS upgrades were always released as DOS executables... because they would run in Windows but also if your system had a floppy disk drive... :-) (obviously very old information nowadays).
Here is a link describing what I was imagining -- a bootable FreeDOS image: http://pingtool.org/bootable-dos-iso-bios-upgrade/ -- note this person combined FreeDOS and some Windows utility to make a bootable disc image. I suspect you could cobble together something similar using linux utilities, too.
--> HOWEVER I do not know if the bios upgrade .exe provided by Lenovo can run in DOS mode... I haven't tried it.
ANOTHER option (I haven't tried!!!) would be to create a bootable Windows PE image. I believe there are some around, but now that I look, all the procedures involve creating the image from within a Windows environment (a Google search points to several options). Oh and of course Windows PE technically requires an existing Windows license, though I don't think it checks.
Making a DOS image...
Today I realized the Ubuntu USB "Startup Disc Creator" only seems to work with linux images (maybe only Ubuntu). To create a FreeDOS USB you'll need to install unetbootin and use that utility. As it turns out it can make a bootable USB from (an older version of) FreeDOS on its own, but I just used it to create a FreeDOS 1.1 image. (just to see if I could)
UPDATE: I installed FreeDOS 1.1 to the USB stick with unetbootin. I couldn't get it to boot. SO I had unetbootin create a FreeDOS 1.0 image. It booted, but I didn't play with it long. The next step would be to try copying the Lenovo BIOS update .exe to it to see if it runs, but I don't want to run it again on MY system....
I did notice unetbootin knows how to create all sorts of images on its own, including some other kinds of rescue images, but I haven't read about them.... you might have a look?
Here's what I did (a week or two ago) to update my BIOS:
I still have Windows cluttering my hard drive for just this reason (based on sad experience with a Dell). I downloaded the .exe file and copied it to a USB stick, booted into Windows, and opened the .exe file. The software ran as a Windows installer. It asked me to approve it, installed something somewhere, and then asked me to reboot Windows to do the actual install. BY THE WAY, the actual install looked sortof like a DOS installer, so it's POSSIBLE the .exe might run under FreeDOS.
P.S.: Lenovo seems to have done something odd to their own bootable disc image to make it look "empty" to some linux software -- I confirmed there IS an image in the file (you can dump it and see things in it) but the Image Mounter and other linux utilities think it's an "empty" file. I suspect you could modify a character or two somewhere and make it easier to burn or make a USB stick in linux.

System Programs Not Working (BUILD 9926)

Ever since the update the following will not work:
PC Settings
Start Menu
New Cortana
Action Center
I know it's a bug, but is there any temporary fix? I've tried restarting a few times to no avail.

Hi Deathvein,
What is your current situation?
The slow performance of Windows 10 might be caused by the upgrade process. You may take a try to perform a disk cleanup and then check if the situation would turn better.

How to call Operating System commands / external programs from within APEX

Hi,
Can someone please suggest how to call Operating Systems commands / external programs from within APEX?
E.g. say I need to run a SQL script on a particular database. SQL script, database name, userid & password everything is available in a table in Oracle. I want to build a utility in APEX where by when I click a button APEX should run the following
c:\oracle\bin\sqlplusw.exe userud/password@database @script_name.sql
Any pointers will be greatly appreciated.
Thanks & Regards,

Hi Guys,
I have reviewed the option of using scheduler and javascript and they do satisfy my requirements PARTIALLY. Any calls to operating system commands through these features will be made on the server where APEX is installed.
However, here what I am looking at is to call operating systems programs on client machine. For example in my APEX application I have constructed the following strings of commands that needs to be run to execute a change request.
sqlplusw.exe user/password@database @script1.sql
sqlplusw.exe user/password@database @script2.sql
sqlplusw.exe user/password@database @script3.sql
sqlplusw.exe user/password@database @script4.sql
What I want is to have a button/link on the APEX screen along with these lines so that when I click that link/button this entire line of command gets executed in the same way it would get executed if I copy and paste this command in the command window of windows.
Believe me, if I am able to achieve what I intend to do, it is going to save a lot of our DBAs time and effort.
Any help will be greatly appreciated.
Thanks & Regards,

Onekey Rescue System Failed-3000 system G430.

Hi there,
My G430/Vista can operate Onekey Rescue System..(i had done this before and it's fine) but after format the hard drive.
my G430 cant run the system/program with suppose to show window logo on startup. evertime i restart my laptop it's still same.. just shown black screen with _???
why this happen?? and how can i recover or get back the recovery image? .wsi file??
and i try to install win xp but blue screen come up when window starting??
somebody please help me...

OneKey is a system set up in your S10's hard drive specifically for recovering your operating system in case of corruption. You're laptop includes a NOVO button, which when the laptop is off it boots into a hidden partition which enables you to recover to the factory form [as when you bought it]. You must not modify partition sizes otherwise you may lose this function. There is a download on Lenovo's website which allows you to install OneKey 6.0 on Windows Vista. This allows you to create a backup for your operating system in it's current state. You can uninstall all the bloat, install additional software [i.e. Microsoft Office, Nero] and then create a backup image which you can use for recovery.

I can't open Itunes on my laptop. "Itunes has stopped working. A problem causes the program to stop working correctly. windows will close the program and notify you if a solution is available" is the message. what is the problem here?

I can't open my Itunes program in my laptop computer with windows 8. the message is "Itunes has stopped working. A problem causess the program to stop working properly. windows will close the program and notify you if a solution is available". I reboot the machine, Uninstall and re install the Itune program, stilll the same message pops up.

The first thing to try is System Restore to take you back to a point in time when it did work. If that is not successful, create a new user on the computer. log in with that and see if ID will start. This will tell us if the problem is in the system/program or the user account.
If it works in a new user account, see Replace Your Preferences and in addition to replacing the prefs, empty the InDesign Recovery folder that will be in the same location and the InDesign SavedData file.
