How can i get the length of a DefaultTreeModel

i got a tree structure (DefaultTreeModel), now i want to know how many level of this tree, what method can i call to get the length of the tree???

What sort of TreeNodes do you have in your Tree? If you have DefaultMutableTreeNodes in there then you could call the getDepth method on the root node. That operation is expensive though.
Good Luck

How can i get the length of a string with Simplified Chinese?

when i use eventwriter to add content to a xmldocument,there are some chinese simplified string in it,i use String.length() for the length ,but it is not correct~how can i get the right length for eventwriter?

Below is a simple patch for this problem. Using this patch you need to pass 0 as the length argument for any XmlEventWriter interfaces that take a string length.

How can I get the length of a sequence using script

I am trying to get the length of an image sequence that was imported using importOptions.sequence. I need to check that the length is a correct number, and if it is too short/long it gives an error message.
Is there a way to do this?
Thanks

//Assumes that your clip is the first item in your project
var a = app.project.item(1).duration;     //Returns clip length in seconds
var b = app.project.item(1).frameDuration     //Returns a single frame length in seconds
var c = a/b;     //If you divide the clip duration by the frameDuration, you should get clip length in frames

How can I get the InsertionPoint with FindText method.

Hi All:
In indesing script, I can find "abc text" with FindText method, and I want to insert a image here, but how can I get the insertionPoint(the FindText method return an object)? any help?
Thanks in advance.

What seems to be the problem?
>app.findTextPreferences.findWhat = "text";
>text = app.activeDocument.findText();
>alert ("insertionpt "+text[0].insertionPoints[0].horizontalOffset);
gives (as expected) the horizontal position of the first occurrance of "the".
Note that findText returns an
i array
of found items; its length may be 0 (not found), 1 (only found once), or any other number.
InsertionPoints is
i also
an array. Perhaps you expected it to be 'the' position of the found text -- it doesn't. It's an array of all insertion points in the found text.
'The' position of the text (in its parent text) is something like text[0].index ("The index of the Text in the collection or parent object.")

How can i get the failed row numbers in batch insertion?

Afeter execution of batch insert operation into a table, i use OCIAttrGet() to get the error number of insertion, as expected, it returns the correct number. however, when i use OCIParamGet() to get an error handle and then to get the exact failed row numbers , OCIParamGet() returns -2 , means "INVALID_HANDLE". can anyboy tell me why ? how can i get the exact failed rows?
the snapshot of my code :
int errNum = 0;
int nRet = 0;
nRet = OCIAttrGet((dvoid *)m_pIIOdbc->m_pStmtAll,OCI_HTYPE_STMT,&errNum,
 0,OCI_ATTR_NUM_DML_ERRORS, m_pIIOdbc->m_pErrHandle);
if (errNum)
 OCIError* pErrHndl;
 int* pRow_off = new int[errNum];
 for (int i = 0; i < errNum; i++)
 nRet = OCIParamGet(m_pIIOdbc->m_pErrHandle,
OCI_HTYPE_ERROR, m_pIIOdbc->m_pErrHandle, &pErrHndl, i + 1);
 nRet = OCIAttrGet (pErrHndl, OCI_HTYPE_ERROR, &pRow_off, 0,
 OCI_ATTR_DML_ROW_OFFSET, m_pIIOdbc->m_pErrHandle);
 delete []pRow_off;

now the code is :
OCIEnv *m_pEnvHandle;
OCIError *m_pErrHandle;
OCIError *m_pErrHandle2;
OCIServer *m_pSrvHandle;
OCISvcCtx *m_pSvcHandle;
OCIStmt *m_pStmtExec;
OCIStmt *m_pStmtAll;
OCIError** m_pErrorHndl;
int* m_pRowOff; //the array that will contain the failed row numbers
int m_nArrayLength; //length of array in once batch operation
int m_nErrNum; //error number
int m_nSucCount; //successful record number
//initialization
//m_nArrayLength is a parameter passed in, so i can not tell the exact length of the array, dynamic space allocation is needed
m_pErrorHndl = new OCIError*[m_nArrayLength];
m_pRowOff = new int[m_nArrayLength];
//execution
OCIStmtExecute(
 m_pSvcHandle,
 m_pStmtAll,
 m_pErrHandle,
 (ub4)m_nArrayLength,
 (ub4)0, (OCISnapshot *)NULL, (OCISnapshot *)NULL,
 OCI_BATCH_ERRORS
//get successful records number
m_nSucCount = 0;
OCIAttrGet((dvoid *)m_pStmtAll,OCI_HTYPE_STMT,&m_nSucCount,
 0,OCI_ATTR_ROW_COUNT, m_pErrHandle);
//get error numbers
m_nErrNum = 0;
OCIAttrGet((dvoid *)m_pStmtAll,OCI_HTYPE_STMT,&m_nErrNum,
 0,OCI_ATTR_NUM_DML_ERRORS, m_pErrHandle2);
//get failed row numbers into the array
if (m_nErrNum)
 //get failed row numbers into the array
 for (int i = 0; i < m_nErrNum; i++)
 //initiallize error handles OCIHandleAlloc((dvoid*)m_pEnvHandle, (dvoid**)&m_pErrorHndl,
 OCI_HTYPE_ERROR, (size_t)0, (dvoid**)0);
 OCIParamGet(m_pErrHandle, OCI_HTYPE_ERROR, m_pErrHandle2, (void**)&m_pErrorHndl[i], i);
 OCIAttrGet (m_pErrorHndl[i], OCI_HTYPE_ERROR, &m_pRowOff[i], 0,
 OCI_ATTR_DML_ROW_OFFSET, m_pErrHandle2);
now, if batch insert is executed, eg, there are 10 records to be inserted, thus m_nArrayLength is set to be 10. There are 5 records of the 10 have exist in database, so some of insert operations will fail. After execution, m_nErrNum is 5, and i can get the failed row numbers.Everything seems go well.
However, if batch updata is excuted, eg, 10 records to be updated, m_nArrayLength is set to be 10, and also there are 5 records of the 10 have exist in database. After execution, the OCIStmtExecute() returns 1, m_nErrNum got by
OCIAttrGet((dvoid *)m_pStmtAll,OCI_HTYPE_STMT,&m_nErrNum,
 0,OCI_ATTR_NUM_DML_ERRORS, m_pErrHandle2)
is 0, and m_nSucNum is 5. Why?? how can I get the rows that fail? i have to know which rows do not exist in database??

How can i change the length of a narration ?

how can i change the length of a narration ?

Thanks for the reply.
Still not sure what version of Premiere Elements that you are using. But, the following should apply nonetheless
What you describe is what I have described in my blog post and for which I have discussed all aspects of the issue. There
is no workaround to force the program to give you more than you are getting now without other clips also on the track(s). The
blog post just about says it all.
You might have to weigh the pros and cons of
a. Recording your narrations as .wav files in a free audio editor such as Audacity
Audacity: Free Audio Editor and Recorder
and then importing those into your Premiere Elements project with Premiere Elements' Add Media/Files and Folders/Project Assets from where you drag the narration to the Narration Track.
b. Put any video clips on the Timeline when you are recording your Premiere Elements narrations with its Narration Tool. Then remove these video clips and replace them with the real thing when you are ready to put narration and clips into the project.
Please let me know if you are OK with the details.
Thank you.

I am having macbook air recently my iphotos did not open and was showing report apple and reopen but i came to know that by pressing alt and iphotos i open an new photo library and stored the pics but now how can i get the pics which i had in the earlier

i am having macbook air recently my iphotos did not open and was showing report apple and reopen but i came to know that by pressing alt and iphotos i open an new photo library and stored the pics but now how can i get the pics which i had in the earlier photo please help me to recover my photos

Well I'll guess you're using iPhoto 11:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

How can i get the all values from the Property file to Hashtable?

how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain

how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............

The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is);

Delete the broken links in iTunes then look at your purchased list to redownload.
If this happened because you were deleting files from the iTunes folder in Finder, don't. You have to let iTunes do all the deleting and moving or you will end up with broken links.

Since that password is tied to his Apple ID, you will need to contact Apple; as far as I know, it will be a somewhat lengthy procedure and you will need to furnish necessary paperwork (including a death certificate as far as I know). Best to either stop at an Apple store or call them to find out exactly what it is you need to do.

Sync is only oneway, from PC to your device. Unless you have the music on your PC, iTunes is going to wipe out what you have on your device if you are syncing to a new library.
You can only transfer Purchased music over to Itunes on your PC.

How can I get the photos from my old icloud backup on to my computer?

I got a replacement phone and now there are 2 iphone backups. There's the old phone with the pictures on it I would like to put on to my windows 8 pc. I can't figure out how to get them. I can't restore them to my iphone because I already have another file in icloud for that. How can I get the old file with my pictures on to my computer??

You can only access them by restoring the backup to your phone. You can backup your phone (such as by backing it up to your computer using iTunes), restore the old backup, transfer the recovered photo to your computer (iOS: Import personal photos and videos from iOS devices to your computer), then restore the backup you made earlier to return your phone to its current state.
