How to calculate and set a value of colunm on each update of the line
Hi allFor example, I have 4 coulmns in a picture and the Col4 must be derived and set on each update of the line operation (irirespective of which column is updated).
The logic for the derivation is not simple, if I prefer it as a separate method (call uses WS).
Anyone can guide me please in this approach. Thank you!
Thank you
-John.
Is this must be done on the update or insert also?
If this is to update, you can check the operation if it is updated or insert or delete by substituting the doDML() in your entity impl
doDML (int operation, Transaction e) {}
if(e == DML_UPDATE) {}
/ PIN to call the stored procedure * /.
}
}
Kind regards

How to get and set values a HSlider
Hello
I haven't used flex for a while and I'm a little slow today. My question is simple: how to get and set my HSlider values in a class. My HSlider lives in an mxml file and class lives in a separate actionscript file. First of all, I want to get the value of the hslider. I use property change in the hslider to call a method in my class called Update(. ) In my class, I have the function called Update() and Interior using the id of the cursor to get the value of it. The compiler is complainiing of 1120: access of undefined property hslider. I gave an example of pseudocode below:
MXML
< mx:HSlider id = minimum "hslider" = "0" maximum = "100" value = "100" dataTipPlacement = 'top' tickColor = '0 x 323232 '.
snapInterval = "1" tickInterval = '10' allowTrackClick = "true".
liveDragging = "true" change = "aClass.Update ()" / > "as file
public void Update (): void {}
myVar = hslider.value / 100.0;
}Think how and then set the value of the hslider?
Maybe the update to this other file function must accept a parameter of the event and then you can probably get this value from the event
or maybe give the function a parameter of the cursor
change = "AClass.Update (hslider.value)" "
public void Update(value:int):void {}
myVar = value / 100.0;

How to get and set the length and the width of the content of the layer?
How to get and set the length and the width of the content of the layer
All layers are packed not equal. a layer as adjustment have no limits. Layer to smart object can have two different sizes. The size of the object and the size of the object may be transformed. All smart object layers have an associated transform. To transform a smart object layers you need to work with the size of the object the generated pixels fot the layer. Text layer can be resized with a transform or by changing the font size. Pixelated layers are resize via a transformation. The script method is resize. When you resize the number of pixelsits made by interpolation. You can specify what method to use or set Photoshop interpolation preferably by default.
There is also a bug in Photoshop scripts if you pause the story said make a selection and use resize. Photoshop will properly support up to a State before where you suspended history. This bug seems to be in all versions of Photoshop.
If you look ate the script in my bug report, you should get a good idea of how to resize a layer.

A statement UPDATE changes the line if the update changes the column even value?
HI -.
I have a main classification and the corresponding audit table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211
Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time. He is not able to determine that the value is the same.
My goal is to load the audit table data if the value in a cell in the main table is really have changed.

I have a main Table and the corresponding Audit Table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211
Why?
You try to resolve what made you what are the PROBLEM that select as the solution?
Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time.
Yes - it is EXACTLY what you say that you wanted to do and EXACTLY what the code does in this article.
He is not able to determine that the value is the same.
I think you mean that the code does NOT check if the value is the same. You can certainly change the code to do this check. But I have a question to start with your need for such a solution.
My goal is to load the audit table data if the value in a cell in the main table is really have changed.
OK - then modify the code to check EACH COLUMN and compare its NEW value to the OLD value and insert only the table of audit if SOME (or columns you care specifically) have changed.
A statement UPDATE changes the line if the update changes the column even value?
It depends on what you mean by 'change the line '. Of course to update a column with the SAME value does not change the resulting data value.
But the physical structure of the line, the location of the pieces of line and information in the header block (YVERT, etc.) will change. And, as others have said Oracle doesn't know and doesn't care, so if the new value of a column is the same as the old value will create redo, undo and the rest.
Start over and tell us what PROBLEM you're trying to solve. Then we can help you find the best way to solve it.

How to get and set permissions of VM
Hello
I'm trying the new powershell CLI for VMWare ESX.
Y at - it a way to get and set permission on a Virtual Machine, not host.
Get - VM, I get my VM, but I do not see effective permissions on this object.
Thanks for your help!
No, that would be a little different.
To create a new permission on a virtual machine, you will need using the New-VIPermission cmdlet.
You can do the following:
Get-VM-name MyVM | New-VIPermssion-role (Get-ferrule-name 'Admin') - main "ADDomain\ADGroup."

Updated as updates of the lines checked and unchecked.
At the APEX of 4.1, I created a tabular presentation by using the wizard. I chose UPDATE and DELETE. I didn't insert. I chose the primary key rather than line number in the wizard.
If I change one row on the screen and click SUBMIT, it will update the table if the line is activated or not. This is how it is supposed to work? When you delete, only the registered lines are deleted.
Moreover, I am happy that he behaves this way because this behavior fits my needs. But it bothers me because I have not deliberately set up this behavior.

I have Windows XP SP3 OEM CD. I want to use to create a 'new' Windows XP OEM CD slipstreamed which would include at each update published security for XP since Service Pack 3. After researching this project for a bit, I noticed that an unholy amount of security updates have been released since Service Pack 3. My main question is how can I get all these security updates without having to monotonous download each individually? Or is this the only way? Is there a website that is legitimate and can be trusted who was respected and compressed these updates of security in a single file that can be downloaded? How can I incorporate these security updates? It is even possible to integrate these security updates or would they simply be performed one after the other during the installation of Windows XP?

Each update of the Mac App Store downloads and installs twice
When I hit "update" for an application on the Mac App Store, it downloads, installs and continues to show an update. I hit "update" again, let it download and install once more. Even after waiting a few minutes in between.
It seems that when I click on "update all", apps always download and install both times, but automatically, without having to double click me. It is even clearer that this behavior occurs when one of the applications is open, I get the warning twice as much as the application runs.
This has been going on during some time, perhaps at the time of the update to El Capitan.
None of these applications are installed in several locations on my Mac.
I tried the advice of following Linc on this thread and delete/var/folders/zz/zyxvpxvq6csfxvn_n00000s0000068, but it did not help.
Please test after taking each of the steps that you have not already tried it. Stop when the problem is resolved. Back up all data before making any changes.
1. open a search window by pressing the command-F key combination in the Finder. Select the Mac as the scope of research and the research of the app (s) in question by name. Delete all obsolete or duplicate copies that you find.
2. If the search results appear to be inaccurate, rebuild the Spotlight index. If you try to search now, there will be an indication that the indexing is in progress.
3. triple - click anywhere in the line below on this page to select this option:
~/Library/Containers/com.apple.appstore
A right click or Ctrl-click on the line and select
Services ▹ reveal in Finder (or just to reveal)
of the contextual menu.*, a file must open with a selected item. Quit the application runs. Move selected item to the trash. Restart the application and test.
* If you do not see the item context menu copy the selected text in the Clipboard by pressing Control-C key combination. In the Finder, select
Go ▹ go to the folder...
from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.
4. If the previous steps do not resolve the problem, leave each app in question and uninstall it by following the instructions on this page. Alternatively, you can drag it into the Applications to the trash and empty folder. You have created the data files will be preserved. In Spotlight, check that there is now no copy of the application on your system. Download your purchase history in the App Store.

How to determine and set the width/height of a movie
Hi all
It is perhaps a fundamental issue, but I can't seem to find this information anywhere. I want to determine what the default size, in pixels, is a project of actionscript 3 to be able to set the width and height of an individual and to be displayed in the browser at its actual size.
The project I'm working on that will be used on a Web page with a bunch of other data no flash so it is important, it is the right size and fits well into the rest of the content.
So far, I've seen I can force the values by editing the files in the html-template folder and I can query the size of the stage object, but really what I want to do is find these values inside Flex Builder and for run/debug mode display the full-scale project, not to stretch out it. I can want to resize it upwards or downwards later on or to allow the resizing of the browser scaling, but I want to default to actual size for development, if you see what I mean :)
Thanks in advance,

How to get and set the size of the pool AM in life
Hi, I want to get and programmatically, set the following parameters:

Maximum Pool size (
jbo.ampool.maxpoolsize
)Referenced Pool size (
jbo.recyclethreshold
)The maximum lifetime of Instance (

)--------------------------------------------
In AMImpl or other place?
Is it methods?
Thank you.
To get information about the pool, you can use code like this in your applicationModuleImpl
help to dump pool statistics to log
private void dumpAMPoolStatistics() {}
Download the pool manager
PoolMgr poolMgr = PoolMgr.getInstance ();
get the managed pools
Key of the poolMgr = enumeration. getResourcePoolKeys();
If (key! = null) {}
If (keys.hasMoreElements ()) {}
can handle several pools, we will get the name of first successful
String poolname = (String) keys.nextElement ();
System.out.println ("pool of AM name:" + poolname);
get the AM pool
ApplicationPool pool =
PoolMgr (ApplicationPool). getResourcePool (poolname);
Journal of diagnostic AM pool
PrintWriter out = new PrintWriter (System.out, true);
pool. dumpPoolStatistics (new PrintWriter (out));
out. Flush();
}
}
}
Or read Getting Application Module pool statistics to help with setting the size
I'm not sure you can change the settings at run time. As far as I know, the pool bed settings only when it is first created.
