What are the inner workings of the grid in forms?
Hi, I have some doubts, I want to know what are the inner workings of the grid in forms.
1. how forms followed the value change in the grid?
2. when we run the query that we will get the selected lines, then we changed some values in certain fields in the grid, how it follows the change in value? .how he knows the process is update or insert?
It is this that my concept, when we realized the request forms will be store values in the tables with rowid.i thought a lot more, but I can't any idea on it.any help me?
You just want to understand the functioning of the forms or you encounter some difficult techniques in certain areas? If you have a hearing problem, please describe, and we can try to help. If you try just to know how it all works, I would recommed referring to Forms Builder online help.
In help, search for information on GET_RECORD_PROPERTY. This part of the documentation provides a pretty good explanation as to what is happening and how to determine the current state of a folder.
In short, when you make a change to a field that represents a recording of the db, a SELECT for UPDATE is issued. This causes the recording to be blocked. Actually change value, we monitor internally. I won't go into the details on how we do here.

I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.
AWR estimated AXIEM most powerful plan EM Simulator around. AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws. Here is a summary of the differences:
Mesh
- EMSight must mesh the nearest grid drivers using rectangles. This causes the mesh to have more elements mesh when there are small and large geometries. The grid should be small enough to capture the small geometry but then causes large geometries to mesh more. In addition, angled or curved structures causes inefficiencies mesh.
- AXIEM STS forms, rather than a grid. In addition, the mesh can be rectangle or triangle. This allows a much more efficient mesh. AXIEM generally have a much more efficient
- AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh. EMSight does not have this feature.
- AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)
Ports
- The ports are for the most part similar, but parasites due on AXIEM ports are less. In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.
- Ports can be added to most any place in geometry with AXIEM. For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.
Problem solvers
- EMSight does not have a low frequency Solver. Stop low-frequency and then extrapolate to DC. This usually works well, but you must take into account if the extrapolation is accurate. AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.
- Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment. It has a special algorithm to break the question of memory, but the question of time is the killer. AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn). In other words, AXIEM can solve a lot of bigger problems than EMSight.
- Several AXIEM processes are multithreaded as EMSight.
Speaker
- EMSight is inside a perfect driver side wall. This works well if you the circuit is in the same cavity. If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes. AXIEM is not here. AXIEM does not currently have to simulate a perfect driver side wall.
I don't know that I missed a few aspects of the tools. From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

What are the "exclusive" for the version of the Apple Watch Nike Siri?
I'm interested in the Nike + version of the series 2 Apple Watch, but not knowing if additional features are really a selling point for me. I have connected more than 2000 miles on the Nike application on my iPhone, so I will definitely stay with the same application on the watch... but what are the commands of Siri for Nike + which won't be available for non-Nike version?
Hello
During the keynote of yesterday, it was mentioned that a shortcut to start a race is just tell Siri to 'run '.
In addition, neither Nike nor Apple has yet specified what are the other commands.

Your username appears to be rather ironic.
Given the richness of the information you provided, I guess, whatever the version of Pages that you use, you've opened the model selector.

Whenever people send me emails with embedded videos or images, e-mail is always without the media. It will be just the outline of the empty box where it supposed to be with an icon of the page broken tiny in the upper left corner.
I can't seem to find the cause and the solution, and it happened for a few years already. It has nothing to do with my being always POP and not IMAP account? What are the possible reasons and solutions? Please help, thanks.
Someone sent me a message with a broken image. Here's what I found.
There are two factors that control the display of the remote images in email:
- You must 'Display remote content in this message' or 'Allow remote content' for the sender; See https://support.mozilla.org/en-US/kb/remote-content-in-messages
- change view-> 'Message Body As' was originally' HTML'

What are the original applications for the iPhone 6 s. I had to sync to my iPhone 3g to my new 6s in order to maintain my contacts. Unfortunately, I lost a lot of these new applications. can someone please send screenshots of an iPhone running 6s with applications shown. I need pages other than the home page. Thank you!
'Stock' apps are part of the installation of iOS and cannot be removed, so there is nothing to verify or prove.
When you move to a new phone, just need restoring your old backup phone and compatible applications will be synchronized to the new.
