delete, then add a Sprite clears his graphics.lineStyle
Hello
I have a Sprite that contains another Sprite which is a blue rectangle:
var rectangle: Sprite = new Sprite();
rectangle.graphics.lineStyle (2, 0x0000FF);
rectangle.graphics.drawRect (0, 0, 50, 100);
addChild (rectangle);
Then, somewhere in my code, I want to take a snapshot of the Sprite without the rectangle but I want the rectangle to stay in the Sprite however.
I don't know how or event if it is possible to copy the sprite, so instead, I tried to delete the rectangle, take the shot, and then add the rectangle:
var rectangle: Sprite = mySprite.removeChildAt (rectangleIndex);
var bmp:BitmapData = new BitmapData (mySprite.width, mySprite.height);
BMP. Draw (mySprite);
mySprite.addChild (rectangle);
But then the rectangle is no longer blue but black. Like the sprite.graphics, lineStyle is disabled.
Do you know how I can keep the line style or do you have another idea?
use:
rectangle.parent.removeChild (rectangle);
create your bitmap using rectangle.parent, then
rectangle.parent.addChild (rectangle); restore the rectangle to its parent.

Effectively remove and then add the piece of table 2D
I have a table that is 72 lines (32 channels, 8 channels, 32 channels). I am now taking the middle 8 channels and move it to the end, he will be 32, 32, 8. I could delete a subset of the table, and then add at the end, but I think that it would cause 2 allowances. I wonder if there's a cleaner way to achieve inplace?
Take 2 table subsets (32.8) (40,24) can do two replacements in the original array (index of 64 and 32). I find that it is usually two times faster than delete + rebuild (to research cleaner), which is two times faster than the IPES (slower and uglier by far). Your mileage may vary. It's all the microseconds at this size of table.

How to delete and add traces data?
In my code below, I would add two buttons by clicking on a button ("Remove") that it will remove a trace of data and plot it back by clicking on the button ("Add") as in the examples:
Complete data plotted by the class running
[]
Now with a simple click on a last given to remove button point to disappear

another click and last data point disappear and so on

The reverse operation would be performed by clicking on the 'Add' button: each click will be add a data point

Create buttons as usual; handler of your button 'Delete' should remove the last element of the series and add it to the first element of data deleted messages points. The 'Add' button should delete the first item in the deleted data points and add it at the end of the series. You can bind the property of 'disable' the delete and Add button at Bindings.isEmpty (series1.getData ()) and Bindings.isEmpty (deletedDataPoints), respectively.
Something like
ObservableList() { @Override public void handle(ActionEvent event) { deletedDataPoints.add(0, series1.getData().remove(series1.getData().size()-1)); } }); addButton.setOnAction(new EventHandler () { @Override public void handle(ActionEvent event) { series1.getData().add(deletedDataPoints.remove(0)); } }); removeButton.disableProperty().bind(Bindings.isEmpty(series1.getData())); addButton.disableProperty().bind(Bindings.isEmpty(deletedDataPoints)); Another approach would be to use a separate list for all data points and keep an integer variable storing the number of data points are displayed. The "delete" button would decrement the displayed number, and your button 'Add' would increment the number in the display. Both would also call
series1.getData().setAll(allDataPoints.sublist(0, numberOfDisplayedPoints));You might even be able to make the numberOfDisplayedPoints an IntegerProperty and bind the property data of the series in a pleasant way. This approach runs probably and the previous approach (using a stack of removed points), because you do not directly offer the graph as much more information on what has changed.
Two approaches to problems (in the sense that you must carefully define your application logic and then to implement) if the underlying data is likely to change.

LR3 - Export in JPEG then add to the collection and replace existing?
Is this possible? I know how to export to JPEG, and then add the file in my collection, but is it possible to get it to automatically replace the image I just exported, also delete its settings? Basically just update the original file.
Thank you
I could give you several reasons why this is not a good idea, and also why it is beating all the non-destructive nature of Lightroom...
But no, I don't think that there is an automated way to do it. You must do this manually, but not worth it, it's just not a good idea. Just edit the photo in LR and the modified version appears in your collection, without export and by replacing the existing. Its much easier than what you propose.

Impossible to delete or add songs to the iPhone via iTunes
Dear all,
I'm with my previous iPhone (5s) as a music player - or trying to.
My problem is that when I try to delete or add songs through iTunes, I can't. The "Delete" option is grayed out, outside, on the Edit menu, and - in short - any attempt to delete the songs "on my device' has no value. To add songs through drag-and-drop using manual synchronization is just as ineffective.
Further: many of these songs on my device is dimmed, as if caught in Mid-sync.
I deleted all the music from the device itself, but it still shows upwards as shown above in iTunes.
I use iTunes 12.3.2 what I understand is the latest version. For the record, this is on a Mac Pro Mavericks (10.9.5) running.
Any suggestions (Googling the question is not useful) would be most appreciated.

Group by query, and then add another dimension
Hello guys,.
I am facing problem while building a query. In this, I do group first, and then add a column with a condition more.
I have following data in the table or existing query.
create table tableA (key number (5), newspaper varchar2 (5), varchar2 (5) Blog, available1 number (10), disponibles2 number (1), Type varchar2 (5))
Insert into tableA values (100, ' 501 ', ' 1501', 10000, 8000, "T1")
Insert into tableA values (100, ' 501 ', ' 1501', 12000, 0, 'T2')
Insert into tableA values (200, ' 502 ', ' 1505', 15000, 9000, "T11")
Insert into tableA values (200, '502', '1505', 8000, 1000, "T12")
Insert into tableA values (200, '502', '1505', 5000, 1000, "T13")

Insert into tableA values (400, '503', '1510', 6000, 1000, 'T31')
I created the 'Difference' on the fly using NVL (available1, 0)-NVL(Revenue2,0) as the difference

We must show Type (Sun) only when the difference is high and have to group by (Key1, Journal, Blog) while the rank becomes a.
It is like showing the first 6 columns first and then add the columns of 'Type' later (probably using subqueries).

I'm trying to understand vSphere PowerCLI how to activate the "Options of VAPP" on an exsiting VM (in this case a model freshly cloned) then add properties and select cdrom of the FVO data access such as when the virtual machine is running the FVO - env.xml contains the properties in the CD-ROM drive.
If I use the vSphere client and open the virtual machine settings and click on the tab 'Options' and then select "Options of VAPP" and change the setting to "Enabled" and then select 'VAPP-> Advanced Options' and click on the button 'Properties' on the right, I can add the properties and then I can change them vsphere PowerCLI, but given that these actions are not retained if I clone the virtual machine I need a way to put these in place of vSphere PowerCLI without using the vSphere client to do.
Thanks in advance for the help!Mike
You can use the vSphere API to activate the 'Options of VAPP"on an existing virtual machine, and set properties. For example:
$spec = new-Object VMware.Vim.VirtualMachineConfigSpec
$spec.vAppConfig = new-Object VMware.Vim.VmConfigSpec
$spec.vAppConfig.property = new-Object VMware.Vim.VAppPropertySpec [] (1)
$spec.vAppConfig.property [0] = new-Object VMware.Vim.VAppPropertySpec
$spec.vAppConfig.property [0] .operation = 'Add '.
$spec.vAppConfig.property [0] = new-Object VMware.Vim.VAppPropertyInfo .info
$spec.vAppConfig.property [0].info.key = 0
$spec.vAppConfig.property [0].info.classId = "Property1ClassID".
$spec.vAppConfig.property [0].info.instanceId = "Property1InstanceID".
$spec.vAppConfig.property [0].info.id = "Property_1.
$spec.vAppConfig.property [0].info.category = "Property1Category".
$spec.vAppConfig.property [0].info.label = "property 1.
$spec.vAppConfig.property [0].info.type = "string".
$spec.vAppConfig.property [0].info.userConfigurable = $true
$spec.vAppConfig.property [0].info.defaultValue = "Property1DefaultValue".
$spec.vAppConfig.property [0].info.value = «»
$spec.vAppConfig.property [0].info.description = "Property1Description".
$vm = get-VM-name vm3

graphics.lineStyle thickness pixels?
Hello, in the adobe ActionScript 3.0 documentation the thickness of flash.display.graphics.lineStyle parameter is defined as:
"An integer that indicates the thickness of the line in points;"
How many pixels is at some point? Basically, I need to know how many pixels will take a line created with a certain thickness.
Hey Noah,.
Unlike what the description says, I think the value is actually in pixels. Since the time I used it, the eye it looks like its pixels in.
Here is an excerpt from a page on adobe.com where they show an example of its use. They also refer to as a value in pixels :
"... For example, this line of code indicates the shape named myShape to draw lines that are thick, 2 pixels red (0 x 990000) and 75% opaque:... »
and the code example:
myShape.graphics.lineStyle(2, 0x990000, .75);
Here is the page:

IllegalStateException then add the previously deleted field

Instead of the call
mHomeScreen.add(mHomeScreen.myTextField); ... mHomeScreen.delete(mHomeScreen.myTextField);
I tried to use
mHomeScreen.getMainManager().add(mHomeScreen.myTextField); .. mHomeScreen.getMainManager().delete(mHomeScreen.myTextField);

MAX value query and then add to existing querry
Hi all
Asked me to add some fields to add to an existing query.
I'm having a problem with the initial query, so let's start first, and then maybe I'll be able to figure out how to add it in.
Here is my sample data:
My desired output is the MAX (TASK_SEQ) based on the data set, the TASK_SEQ and the COMPL_DATE should always be recording albums that I'm trying to capture,CREATE TABLE TASK ( TASK_TYPE VARCHAR2 (50 BYTE), TASK_SEQ VARCHAR2 (50 BYTE), COMPL_DATE DATE, REQUIRED_TASK VARCHAR2 (100 BYTE) ); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('ABC',18, TO_DATE('12-MAR-12','DD-MON-YYYY'), 'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('DEF',16, TO_DATE('12-MAR-12','DD-MON-YYYY'),'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('HIJ',12, TO_DATE('09-MAR-12','DD-MON-YYYY'), 'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('KLM',15, TO_DATE('12-MAR-12','DD-MON-YYYY'), 'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('NOP',11, TO_DATE('11-MAR-12','DD-MON-YYYY'), 'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('QRS',20, TO_DATE('29-MAR-12','DD-MON-YYYY'), 'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('TUV',13, TO_DATE('11-MAR-12','DD-MON-YYYY'), 'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('WXY',19, TO_DATE('30-MAR-12','DD-MON-YYYY'), 'Y'); INSERT INTO TASK (TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK) VALUES ('Z',24, TO_DATE('04-APR-12','DD-MON-YYYY'), 'Y');
such as:
{Europe}
TASK_TYPE TASK_SEQ COMPL_DATE REQUIRED_TASK RNK
Z 24 4 4 2012 Y (DO NOT WANT THIS)I have this code that I thought would work, but not as of yet - it returns all rows and ranks eac as 1. {code} WITH DST AS ( SELECT TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK, RANK () OVER (PARTITION BY TASK_TYPE ORDER BY COMPL_DATE) rnk FROM TASK ) SELECT * FROM DST WHERE rnk = 1 {code} And this yields basically the same results: {code} SELECT TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK FROM TASK WHERE (TASK_TYPE, TASK_SEQ) IN (SELECT TASK_TYPE, MAX(TASK_SEQ) FROM TASK GROUP BY TASK_TYPE ) {code} Thanks for taking the time to look. GHello
GMoney says:

Be careful. The keyword tiny must code. (It must be spelled correctly, too.)
What is the desired line or line that you don't want? If this is the desired line, so you were on the right track with your first attempt. Try this:WITH DST AS ( SELECT TASK_TYPE, TASK_SEQ, COMPL_DATE, REQUIRED_TASK, RANK () OVER (ORDER BY COMPL_DATE DESC) rnk FROM TASK ) SELECT * FROM DST WHERE rnk = 1 ;Exactly what you have published, with the exception of the analytical clause.
'PARTITION BY task_type' means a separate set of numbers (starting with 1) assign to each separate task_type. Since task_type is unique, this means that each line is #1 in his own little world. If I understand the problem, you want (except ties) only 1 rank for the entire result set. This means you don't at all want a PARTITION BY clause. PARTITION BY is never required in any analytic function.
"ORDER BY compl_date" means that the first compl_date gets rnk = 1. You want the latest comp_date to get #1, so you must specify descending order. Note that this has nothing to do with task_seq. It you want to display the line with the highest task_seq, then the rnk column would be defined as:RANK () OVER (ORDER BY task_seq DESC) rnkIf you know that the line with the upper task_seqs is always compl_dates later, then it does not matter that you use. Remember to descending order.

A single button that deletes and adds MCs
I am trying to create a button that, when clicked first, will add a MC to the scene. Then, on the second and subsequent clicks delete the existing MC and replace it with a new one. The code I use is:
Stop();
Draw1.buttonMode = true;
Draw1.useHandCursor = true;
Draw1.addEventListener (MouseEvent.MOUSE_DOWN, dealTheCard);
var alreadyDrawn:Boolean = false
function dealTheCard(event:MouseEvent):void {}
If (alreadyDrawn == true) {}
this.removeChild (drawnCard);
trace ("removed card")
}
var drawnCard:MovieClip = new deck1();
alreadyDrawn = true
addChild (drawnCard);
drawnCard.x = 60;
drawnCard.y = 50;
drawnCard.gotoAndStop (Math.ceil (Math.random () * 11))
}
For some reason, I get an error saying:
TypeError: Error #2007: child parameter must be non-null.

How to add a Sprite in a container and animate it with AS3?
I am quite experienced Actionscript 3 programmer (I mainly work in the Flash IDE), but come back to Flex after a 2 year hiatus. I know this may seem ridiculously simple, but how do I add a container (i.e. a Sprite object) on stage in flex and animate a Sprite object inside? I want to make a VU-meter for audio out an application which is simply two rectangles that will resize vertically to the level of the master channel volume.
In AS Flash/pure, I would simply create 2 Sprite objects, add them to the stage or some other container Sprite and then proceed to change their scales Y at regular intervals with the following code:
protected function enterFrameHandler(event:Event):void
{
If (isPlaying)
{

With MXML, I am at a complete loss!
Where should I put the Sprites (what container in Flex should I add them also)?
How can I add them to a container?
What should I use to keep the regular calendar (EnterFrame or a Timer object)?
I bought 2 books on Flex and doesn't really seem to take account of the fact that I want to animate in Actionscript 3, FLEX NO! They suggest using the animate class and class AnimateInstance, etc... This seems much more complex and adds layers of abstraction that is really not needed! One of the reasons that I stopped using Flex 2 years has been done the same type of problem I'm facing here! MXML is great when it comes to components and to simplify the page layout, however, when we want to do something out of pure standard with ActionScript, MXML adds a convoluted layer of complexity which is not always as intuitive as one would expect! Maybe I go about it the wrong way, but I'm used to doing things with ActionScript only!
Thanks in advance for any help/advice anyone can give!

MXML is a markup language and allows people to easily put all the applications using
a setting that common componentizes models and features. It is not
As you complete as programming language can almost think MXML as a
language of macros.
If you look at the framework itself, it is almost entirely written in
ActionScript (with the exception of the spark skins), because we try to encapsulate
things at low altitude.
Then write your component did you and add it to your application via MXML. Follow it
recipes for the custom components in the doc. It's more work that simply write
a simple flash application, but the standard benefits of encapsulation and reuse
apply.
And you can always stick a UIComponent in your MXML, give it a fixed
width/height and use this as a sprite.

Jacquie Lawson advent calendar no longer works
My timetable for the advent of Jacquie Lawson worked perfectly from 1 to 13 December inclusive. Now, it does not open and suggests that it is incompatible. Instead he will fly to the side when I click the icon. Original title: program compatibility
