Proper way to close the scene

In my application i am using multiple scenes for multiple windows. when the function is completed, I close the scene using stage stage.close() function. Its written in javadoc that close() function is same as setVisible(false). hence even if i close the stage the resources are not released. what is the proper procedure for it? Any suggestions will be helpful.

Hello user,
When ever you remove the scene the scene resource are not removed from the memory. After you close the stage the rest of the job is given to Garbage Collector of JVM. If you want to manually clear the Garbage. You can call this function.
System.gc();Thanks.

What is the proper way to close all open sessions of a NI PXI-4110 for a given Device alias?

I've found that, when programming the NI PXI-4110 that, if a the VI "niDCPower Initialize With Channels VI" (NI-DCPower pallette) is called with a device
alias that all ready has one or more sessions open (due to an abort or other programming error) a device reference results from the reference out that has a (*) where "*" is post-fixed to the device reference where and is an integer starting that increments with each initialize call. In my clean up, I would like to close all open sessions. For example, let's said the device alias is "NIPower_1" in NI Max, and there are 5 open sessions; NIPower_1, NIPower_1 (1), NIPower_1 (2), NIPower_1 (3), and NIPower_1 (4). A simple initialize or reset (using niDCPower Initialize With Channels VI, or, niDCPower Initialize With Channels VI, etc.) What is the proper way to close all open sessions?
Thanks in advance. Been struggleing with this for days!

When you Initialize a session to a device that already has a session open, NI-DCPower closes the previous session and returns a new one. You can verify this very easily: try to use the first session after the second session was opened.
Unfortunately, there is a small leak and that is what you encountered: the previous session remains registered with LabVIEW, since we unregister inside the Close VI and this was never called. So the name of the session still shows in the control like you noted: NIPower_1, NIPower_1 (1), NIPower_1 (2), NIPower_1 (3), and NIPower_1 (4), etc.
There may be a way to iterate over the registered sessions, but I couldn't find it. However, you can unregister them by calling "IVI Delete Session". Look for it inside "niDCPower Close.vi". If you don't have the list of open sessions, but you have the device name, then you can just append (1), (2) and so forth and call "IVI Delete Session" in a loop. There's no problem calling it on sessions that were never added.
However - I consider all this a hack. What you should do is write code that does not leak sessions. Anything you open, you should close. If you find yourself in a situation where there are a lot of leaked sessions during development, relaunching LabVIEW will clear it out. If relaunching LabVIEW is too much of an annoyance, then write a VI that does what I described above and run it when needed. You can even make it "smarter" by getting the names of all the NI-DCPower devices in your system using the System Configuration or niModInst APIs.
Hope this helps.

What is the proper way to open the app store for ios

Using Air3.1 to develope a game.
I want to have links on my main menu which will open the iOS app store for a specific application.
The only way I have found to do this is by opening a url "http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=<THEAPPIDHERE>&mt=8"
However, while this does work, so to speak, when I try to go back to the application, it starts up as if it had crashed... and it does several "redirects" before it get's where it is eventually going.
Is there a better/proper way to open the app store?
Cheers
dave

Is there a way to close the PO even if one of the item is blocked?

Is there a way to close the PO even if one or more item is blocked?

You can block the items at any time. If you get errors, then you have to take care about them individually.
However you just create problems for standard SAP design of archiving. As I already said, SAP cannot archive blocked orders. Deletion indicator is precondition for archiving.
This deletion indicator is usually set with the archiving prerun program, but it does not set deletion indicators for blocked items.

What is the proper way to move the iTunes (v11) Media folder to an external USB HD?

What is the proper way to move the iTunes (version 11) Media folder to an external USB HD? I have tried to following listed instructions, but although I can get the songs listed, their locations are not found.

Tried the option key, but it would not let me select the copied iTunes folder. Also changed the path for iTunes Media Location folder. But still iTunes is not happy. I could try the alias route, but I don't have an iTunes folder that iTunes is happy with to point it to. All of the songs and even the playlists will come up, but it seems some form of the folder and its files must remain on the internal hard drive. But I want to move it off because it is out of space. Any other thoughts?
I have all of the music etc files what I do not want to lose is the playlists. I don't care about the play counts. I would be glad to reimport all of the songs to the newly designated folder, but won't I lose my playlists?
Thanks for your help.

What is the proper way to use the write method?

What is the proper way to use the OutputStreams write method? I know the flush() method is automatically called after the write but i cant seem to get any output
to a file. The char array contains characters and upon completion of the for loop the contents of the array is printed out, so there is actually data in the array. But write dosnt seem to do squat no matter what i seem to do. Any suggestions?
import java.io.*;
public class X{
public static void main(String[] args){
try{
FileReader fis = new FileReader("C:\\Java\\Test.txt"); //read chars
FileWriter fw = new FileWriter("C:\\Java\\Test1.txt"); //read chars
File f = new File("C:\\Java\\Test.txt");
char[] charsRead = new char[(int)f.length()];
while(true){
int i = fis.read(charsRead);
if(i == -1) break;
// fw.write(charsRead); this wont work
// but there is infact chars in the char Array?
for(int i = 0; i < charsRead.length -1 ; ++i){
System.out.print(charRead);
}catch(Exception e){System.err.println(e);}

Sorry to have to tell you this guys but all of the above are broken.
First of all... you should all take a good look at what the read() method actually does.
http://java.sun.com/j2se/1.3/docs/api/java/io/InputStream.html#read(byte[], int, int)
Pay special attension to this paragraph:
Reads up to len[i] bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len[i] bytes, but a smaller number may be read, possibly zero. The number of bytes actually read is returned as an integer.
In other words... when you use read() and you request say 1024 bytes, you are not guaranteed to get that many bytes. You may get less. You may even get none at all.
Supposing you want to read length bytes from a stream into a byte array, here is how you do it.int bytesRead = 0;
int readLast = 0;
byte[] array = new byte[length];
while(readLast != -1 && bytesRead < length){
readLast = inputStream.read(array, bytesRead, length - bytesRead);
if(readLast != -1){
bytesRead += readLast;
}And then the matter of write()...
http://java.sun.com/j2se/1.3/docs/api/java/io/OutputStream.html#write(byte[])
write(byte[] b) will always attempt to write b.length bytes, no matter how many bytes you actually filled it with. All you C/C++ converts... forget all about null terminated arrays. That doesn't exist here. Even if you only read 2 bytes into a 1024 byte array, write() will output 1024 bytes if you pass that array to it.
You need to keep track of how many bytes you actually filled the array with and if that number is less than the size of the array you'll need pass this as an argument.
I'll make another post about this... once and for all.

Proper way to get the latest published Major version of Document

Hi,
I have a Document Library which has "Create major and minor (draft) versions" enabled.
Now, from my C# application I need to fetch the latest major version of a document from that library.
What is the proper way to do this?
As of right now, I do the following:
return sourceFolder.Files["documentName.docx"]; // sourceFolder is a SPFolder object
Now, I don't trust that this will always give me the latest published major version of the document. Or am I wrong? If I'm wrong, how should I do this?
Thanks!

Problem
When you store critical documents in the SharePoint libraries, sometimes it becomes necessary to track all the changes and to maintain version history for them.
Solution
There might be a time when you would need to restore files back to an older version if any inadvertent change happens. You can also track changes for auditing purposes.
So how does SharePoint allow creating different versions of documents? How does version history work? What are the different types of versions we can maintain for our library or list and how can we revert back to an older version?
SharePoint allows you to enable (by default it's disabled) versioning on lists and libraries. Once enabled, SharePoint will maintain multiple versions of the document or list which gets incremented on each change iteration. There are three different versioning
settings:
No versioning - This is the default setting in which the current version overwrites the older version. There are no previous versions stored. This setting is not recommended especially if your document library contains critical or important
documents.
Create major versions - Also called simple versioning, in this setting the document versions will be numbered with whole numbers, called major versions, i.e. 1, 2, 3, 4 etc.
Create major and minor (or draft) versions - In this setting document versions will be numbered with whole numbers (1, 2, 3, 4 etc.) as well as numbers with decimals (.1, .2, .3, .4 etc.). The whole number is called the major version
(indicates final copy) and the numbers with a decimal are called minor versions (indicates work is still in progress). You use this setting if your document goes through several iterations/drafts/reviews (minor versions) and you want only the final copy (major
version) to be published to a broader audience.
Please note for a list or list items, the only option available for versioning is creating major versions, no minor versions are created.
Once versioning is enabled SharePoint automatically and transparently creates the next version of the document whenever a user updates a document in the library. These are some of the different scenarios when SharePoint will create a new version for your
document or list item:
When a new document or list item is created or uploaded into SharePoint, version 1 is created if the option
Create major versions option is enabled or version 0.1 is created when
Create major and minor (or draft) versions is enabled (not applicable for list items) and when you publish it then next higher major version is created.
When you upload a document with the same name as an already existing document in the library and check the
Add as a new version to existing files check box, the existing file becomes an older version and the new uploaded document will have next higher version number.
When any properties (metadata fields) of the document or list item is changed.
When you Check-in a document that was previously Checked-out.
When you open a document in the associated application, edit and save it for the first time. On subsequent changes no new versions will be created as long as you don't close the application and re-open it.
When you restore the old version of the document.
Please note, although the demonstration in this tip has been shown in SharePoint 2010, the versioning feature has been part of previous SharePoint versions as well.

What is the Proper way to nullify the VECTOR after it's scope is over

I am using Vectors and Array lists at many places in my Web Application, It is neccessary to use them.
In some processes I m storing bulk amount of data into vector due to that the performance of my application will be decreased, for that I have to nullify the vector after it's scope is over.
To nullify I m using Vector v = new Vector()
v.clear().
The above method is suitable in case of simple object data like strings and other values.
But I wanna know that If I m using HashMap and storing bulk data in it and then I m storing each HashMap into vector, what is the proper way.
Does I have to iterate each object of HashMap from vector and set them as null and then set vector as null or directly I can use v.clear() method??
If any having any answer regarding my question then plz reply your each valuable reply will be appriciable.
Thanks in advance......!!

Each time in loop a new object of vector is created and each time I m nullifying it. Thats what I m doing.
Thats why I m nullifying it.
Even if I'll declare it out side the loop then also for the each iteration I have to nullify it cause what I m doing is I m inserting the data into database in each iteration of loop, So that I think it is must to nullify the objects each time.If it is constructed inside the loop then you do not have to nullify it. If it is constructed outside of the loop and you want to empty it for each iteration then just clear() it.

Any way to close the DOS window ?

Is there anyway to close the DOS window, after executing a DOS command in a GUI Java program ?
I keep getting "Please press any key to continue..."..I don't think I can use the System.exit in a GUI Java program?

Yes.
Process p = Runtime.getRuntime().exec(...);
PrintStream out = new PrintStream(p.getOutputStream(), true);
out.print("a");You get the output stream of that process and print an a (which I guess will work just like you pressed a key). I don't know if there has to be a delay before you write this character. If you send it before it has written "Press a key ..", then it might not work. In this case you can add a line with Thread.sleep(1000); to sleep for 1 sec in this example, just before you execute the print statement. Or you can get the InputStream from the process, and read everything it sends and check if/when you get the "Press a key .." text:
PrintStream out = new PrintStream(p.getOutputStream(), true);
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String s;
while ((s = br.readLine()) != null) {
if (s.startsWith("Press a key")) {
break;
out.print("a");something like that..
There might be cases where you don't get a "Press a key" back if the DOS window is big enough to hold all the information (it is possible to change the buffer for DOS windows so they can hold more than 25 lines).

What is the proper way to "close" an application?

I see, after a while, all the apps I've used still show open in the activity monitor and memory available is almost zero. I have to restart the iPhone.
I thought pressing the Home key closed the apps. Apparently not?
-Jim

http://manuals.info.apple.com/en_US/iphone_user_guide.pdf
A very, very few apps will run in the background.
You can close them by going to the recently used apps bar (double click home button), holding down an icon until they wiggle, then tapping the "x"
This should not be needed for most apps. Apps that run in the background such as Tomtom can be turned off from the app itself.

Proper way to test the dual GPU cards?

I'll be receiving my Mac Pro tomorrow and I wanted to know if there is a way to properly put both GPU's through their paces to make sure they are both functioning properly? I've found a few threads where people realize their second GPU ( not used most of the time ) was in fact defective. Is there something on OS X that will test this? I plan to go to bootcamp and do some usual cross-fire tests, but something on the OS X side might be useful.
TIA

My iphone was stolen today,there is a way to close the app??

i lost my photos,sms,diary... there is a way to find or to stop them,so the ******* that stolen my iphone don't saw nothing?

If you used the Passcode Lock feature, nothing on your iPhone can be accessed.
If not, everything on your iPhone is open and available.
If you were accessing a free Apple iCloud account with Find My iPhone enabled with the account settings on the iPhone along with having Location Services enabled, you can try to locate the iPhone with Find My iPhone and/or do a remote wipe. Without having the Passcode Lock enabled with this option, Find My iPhone can be turned off with the account settings.

Are there any way to close the warning "cellular data is turned off" ?

the warning says "turn on the cellular data or use wi-fi to acces data"
I am not trying to access any data requires the internet connection.
how can I turned off this warning ?

The iPhone is designed to be constantly connected. The only way to avoid this warning is to make sure you have cellular data turned on or have a constant WiFi connection.
There is one other option, but that's to pur the phone in airplane mode, which means no phone calls or text message either.
