Have been struggling for days trying to get into the itunes store. Have contacted support with no help. I have been reading how some have typed something into a DOS prompt and have resolved their issues. One stated to "search cmd, right click, and run as admininstrator" but where is this? There was also a post about typing something into the DOS prompt....how do I get to this? Can someone please help??? SOOOOO FRUSTRATING. Thanks much...Carrie (Mike's wife:))
One stated to "search cmd, right click, and run as admininstrator" but where is this?
In the search field in your Vista start menu, type cmd
Next, right-click on the cmd that comes up and select "Run as administrator". -
Clearing the DOS Window in Java
hi
I want to clear the dos screen using java.
I saw 2 solutions on the net(given below) , but both did not work. Can someone advise how I can go about doing this ? I'm
working on Windows2000.
Thanks in advance.
Seema
1. char esc = 27; // ESC code
String clear = esc + "[2J" // note case
System.out.print(clear); // Dos screen should be cleared
2. Runtime.getRuntime().exec( "cmd.exe /c cls" ) ;The escape code approach would only work on DOS windows that are processing ANSI escape sequences. This is something people used to enable all the time back in the pre-Windows days, since it was the only way to do things like clearing screens, setting colours, drawing menus out of text characters, etc. Ansi.sys still exists, at least on Win98 (not sure about NT, 2000, etc.). If you troll through the Microsoft web site or hunt down old books on DOS, you'll be able to find out how to set it up and use it.

Can I pass a command to the DOS prompt from my program?
Hi everyone,
I'm a Java newbee..and have a relatively small doubt:
Can I pass any DOS command to the console,say "for setting a class path " to the DOS PROMPT LIKE "PATH = %PATH%;D:\BEA\WEBLOGIC700\USER_PROJECTS\DOMAIN3" from a simple java program?
Thank u in advance,
moritala.Yes you can call a command in a DOS command shell although obviously not in a platform independant manner.
However it won't have the effect you want it to. The command shell will open, you will set the classpath and then that shell will close - the classpath setting will not affect the already running java application (the one that opened the command shell). To load classes not on the classpath create a custom ClassLoader and use that to load the classes from your new location (this is, in essence how application servers allow multiple applications to have their own sets of classes without interference).
BTW what does this have to do with JDBC?
Hope this helps

The Problem about clearing the system cache
Hi, there!
I'm trying to draw a lot of image in iPhone programming.
I used [UIImage imageNamed].
but it doesn't clear immediately the system cache.
At last it occurs the out of memory.
So I thought using imageWithContentsOfFile, but it works very slowly.
Does anybody know how to clear the system cache?Read Position.flx can execute much faster than 5 ms but as it reads a register that is updated every 5 ms on the board, it reads the same value multiple times.
To get around this problem there are two methods:
Buffered High-Speed-Capturing (HSC)
With buffered HSC the board stores a position value in it's onboard buffer each time a trigger occurrs on the axis' trigger input. HSC allows a trigger rate of about 2 kHz. That means, you can store a position value every 500 µs. Please refer to the HSC examples. You may have to look into the buffered breakpoint examples to learn how to use a buffer, as there doesn't seem to be a buffered HSC example available. Please note that you need an external trigger-signal (e. g. from a counter of a DAQ board). Please note that the amount of position data that you can acquire in a single shot is limited to about 16.000 values.
Buffered position measurement with additional plugin-board
If you don't have a device that allows you to generate a repetitive trigger signal as required in method 1.), you will have to use an additional board, e. g. a PCI-6601. This board provides four counter/timers. You could either use this board to generate the trigger signal or you could use it to do the position capturing itself. A PCI-6601 (or an M-Series board) provides can run a buffered position acquisition with a rate of several hundred kHz and with virtually no limitation to the amount of data to be stored. You could even route the encoder signals from your 7350 to the PCI-6601 by using an internal RTSI cable (no external wiring required).
I hope this helps,

Question about clearing the main drive
Not quite sure if this is even possible (I'm not the greatest with computers) but I'm interested in just cleaning up my hard drive. I've had the computer for a year and just want to get rid of some of the programs I'm not using in order to improve the processor speed, etc.. I know just dragging stuff to the trash doesn't completely clear it, what is the best way about going through my Mac and clearing off old files and programs.
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. Most applications create preference files which 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 located 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.
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.
There are also several shareware utilities that can uninstall applications:
AppZapper
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at www.versiontracker.com or www.mackupdate.com.

Error when I execute an application with the java command in a DOS prompt
Hi:
I have a trouble. I edit the most simple program in Java: hello.java
In DOS prompt, I compile the program. The result is the file hello.class
c:\> javac hello.java
However, I try to execute this program with the command java
c:\> java hello
and the DOS prompt send me an error like this: Java.exe has a problem and must be closed.
I press the option "Don't send". After this, the DOS prompt returns empty and it doesnt execute the application:
c:\>
By the way, in an IDE editor like Gel, the file hello.java is compiled and executed correctly without problems.
I edited other simple Java files, I compiled them succesfully and I can't run them in a DOS pormpt. The result is the same dialog box: "Java.exe has a problem and must be closed".
The question is: Why don't these programs run in a DOS prompt?

How To Boot Windows 7 from Windows 7 DOS Prompt?
I got hit by the GVU virus. Spent a week poking around and made some interesting discoveries!
The GVU virus appears to lock you out of your computer always going to a page in german demanding 100 euros to restore it.
If you reboot while pressing F8 you can get to the debug page which lists several options including boot to DOS prompt.
Select this option.
Windows 7 will boot and ask you to login. Do this.
Your computer will now go to the DOS prompt.
On a second computer I installed an up to date copy of Spybot. Using explorer I found the Spybot directory tree under Program files and copied it to a jump drive.
Remove the jump drive from the second computer and insert it in your sick computer.
On the sick computer you are at the DOS Prompt. Type explorer and press enter.
A window will open similar to windows 7 explorer. Right clicks will not work, but you will find all the usual right click menu items under Files and Edit on the menu bar.
Click View then Refresh to display your jump drive. You may have to do this a couple of times, but your jump drive will appear in the usual spot.
Select the spybot directory on your jump drive and launch spybot. Run a systems scan and delete every thing it finds. Do this step Several times.
Reboot your computer.
Select Boot windows as normal.
It will ask you to login in. Do so.
Your computer will boot to explorer, the version that you saw in step 9.
Press CTL + ALT + Delete then select Task Manager
Task Manager will launch. If you click the process tab you will see only ten or so processes are running.
Click on the applications tab, then in the bottom right corner click on the button New Task.
Type win and press enter.
You will notice that the number of processes will jump to 90 give or take. When CPU use drops to 5% again or there abouts click new task again.
You are now in windows 7 minus the task bar but with networking etc.
Enter a windows program such as Outlook and press enter. Outlook will boot and run perfectly. I suspect that most windows programs will also run perfectly.
I know if you boot from your windows 7 DVD you can repair your system to normal. My question is can I do this without the disk? At this point I can do all my usual tasks, just without the convenience of the task bar and start button. I
am in the middle of unpacking from a move, cannn't find my Windows 7 install disk. I am so close to getting this computer back to running normally but I am not sure what to do next. Can someone help?
Bob JonesHi,
If you system files are corrupted, we can use SFC to fix missing and corrupted system file:

Error when running mortgage calc program from DOS prompt
I have a GUI Mortgage Calculator program. It probably isn't the most efficient use of code, but it gets the job done. I am running java SDK 1.6.0_06. This is a class assignment. We are to compile the code and post the .class file for our team members to run. I am trying to get the .class file to run after I compile it with javac. I used jCreator LE to create it... it compiles and runs there just fine. The program will compile at the DOS prompt, but will not run properly. The following is the error I get (any help would be appreciated):

I believe the problem is with the TNSNames file not having BEQ set up in it. I tried to set up using the Oracle Net Manager and could not find BEQ as an available protocol. Anyone know where to direct me to look in the documentation or can give me some help.
I am a newbie on the Oracle DBA scene and any help would be appreciated. Just been trying to do this since January.Gordon,
Considering that this is a military server I would not post the logon information and server address on a public forum such as this :)
If you are getting the TNS error when submitting the job via OEM, then check that your local tnsnames.ora file on the OEM machine has the tnsnames alias to connect to the target database. When issuing RMAN backups via DOS on the target server you are using BEQ. However, when issuing commands via OEM, you will be using the tnsnames.ora file on the monitoring machine that you've installed OEM on. You will need the tnsnames alias for the RMAN catalog on the target server.
try the following:
set up a tnsnames alias for the target database on the OEM server
open up DOS on the OEM server and type:
rman target jungle/gonzo@<target_database> connect catalog RMAN/[email protected]
Is the target database,catalog and OEM server all on different machines? -
Running java command from DOS prompt
Hi,
When I run java from the DOS prompt (NT) in any other location than the JDK bin directory, I get the following error:
Error opening registry key 'Software\JavaSoft\Java Runtime Environment'
My understanding is to be able to run this from anywhere you need to add the tools.jar file to the CLASSPATH, which I have done.
There is no entry in the Registry for Software\JavaSoft...etc, has anyone any idea what my problem is and how I can solve it?
Thanks in advanceHi,
I am running Java 2 SDK, Standard Edition Version 1.2.2 running on NT. It was installed as part of Oracles JDeveloper IDE and is running on NT.
All I want to be able to do is run java from the command line e.g. 'java myclass', to run a standalone Java program. I can run 'javac myclass.java' to compile the program without any problems, but my understanding is that to do this all I need is to have the '.../java1.2/bin' directory included in the 'PATH' variable, whereas to run the java runtime you need to include the tools.jar in the CLASSPATH variable.
As I said previously I can run the 'java myclass' command from the '../java1.2/bin' directory, just not from anywhere else. As for whats in the code, does not matter you should be able to type just java on the command line and it will come back with an error prompting for the class name. Here is an example of what happens:
I:\>java
Error opening registry key 'Software\JavaSoft\Java Runtime Environment'
However if I change to the correct directory, I get:
D:\oracle\JDev32\java1.2\bin>java
Usage: java [-options] class [args...]
(to execute a class)
or java -jar [-options] jarfile [args...]
(to execute a jar file)
where options include:
-cp -classpath <directories and zip/jar files separated by ;>
set search path for application classes and resources
-D<name>=<value>
set a system property
-verbose[:class|gc|jni]
enable verbose output
-version print product version
-? -help print this help message
-X print help on non-standard options
The contents of my PATH and CLASSPATH variable are shown below, Thanks again.

Win2000 NoClassDefFoundError running java.exe from DOS prompt
I am using Windows 2000 with J2SE v 1.3.1_02 and have a problem when I run java.exe from the command line for classes that are defined to be in a package. I can both compile and run this program from the TextPad editor but when I run it from a DOS prompt I get the error "Exception in thread "main" java.lang.NoClassDefFoundError: MyClass"
My CLASSPATH is set to D:\
The files MyClass.java and MyClass.class are in the directory D:\MyProject
here is the source:
package MyProject;
public class MyClass
public static void main(String[] args)
System.out.println("MyClass main");
Note that if I comment out the package statement and add "." to CLASSPATH then it runs from the DOS prompt. Why does the program run from inside TextPad but not from the DOS prompt? Seems to be some type of bug in java.exe on Windows 2000 when the keyword package is used.It turns out that if you use the main method in a class that declares the package statement you need to use the fully qualified name to run the program. Using this statement works for this problem:
java MyProject/MyClass
the forward slash is required even though is a Windows system.
