Which is a much better use setVisible() or setRendered()

Hi all

Wish you all a very happy new year!

Now come to my question.
I panelBox in my Page ADF, in this, I have three selectOneChoices displaying the LOVs of the country, city, building
Data from LOVS come to ADF BC.

According to the condition that the PanelBox must be displayed. So, I had used the property setVisible (true) or setVisible.
Now when the DB is down from the ADF Page itself is does not properly.

So this time I put the property setRendered (true) or setRendered instead of setVisible (false). Now, the Page is displayed correctly even if the DB is in decline, but with the error message saying the DB is down.


But if the user changes the status to display the Panel several times, will be the performance of the ADF Page will be affected? Since Iam using setRendered property

Please let me know your opinion on the use of property setVisible or setRendered

Thank you
Bardet

Hi kbnaraya,

As Frank says in your case if you use setRendered to false if you LOV1 component programmatically her you need to refresh the Panel box (container of LOV1, LOV2, LOV3) and in fact this will refresh all three of the LOVs.
But if you use false on LOV1 setVisible, you can then use the PPR on the hidden component (LOV1) and it will not regenerate the LOV2 and LOV3.

So according to me setVisible is best for your use case. Also in the case where you are using setVisible then your LOV1 is actually downloaded to the client, but as you have only 1 such component this will not slow down page loading as well.

Thank you

  • Which account you want to use to run this program?

    A week ago, just after installation of Microsoft Update, when I start my computer, a box came who said: run as.  Which account you want to use to run this program? [x] current [of user\Owner] protect my computer and data from unauthorized program activity. This option can prevent computer viruses from harming your computer or personal data, BUT selecting it might cause the program to function properly. Current use is already checked, and my options are to check I want is not protected, or cancel. I tried all the options, or just close the box. What is the devil? Why should I see it every time I start my computer? And, more importantly, why would I want to when, "selecting risk the program work correctly?" How can I get rid of this annoying box, since I already have Kaspersky as a guard dog? Thanks, Tess

    No, you are not condemned.

    To make the warning "diagnostic mode" Begone, re - run msconfig and select the radio to "Normal startup" button (cela re - automatically checks the Java update box, as well as all the other boxes you might get UN-ticked).

    The way you described your original message is a bit confusing.  Messages request 'which account you want to use' - what are the choices presented to you?

    Run as.  Which account you want to use to run this program? [x] current [of user\Owner]

    Is the account that you sign normally called "owner"?

    You have an x in the box in front of "Current user" - If the current user IS 'Owner' what does the other box reference?  It may be a better representation of the pop - up:

    Run as
    Which account you want to use to run this program?
    [] Current user / owner
    [] Protect my computer and data from unauthorized program activity. This option can prevent computer
    viruses from harming your computer or personal data, BUT selecting it can cause the program to
    work correctly.

    That is, we really give you a choice of the accounts, but only the current account or anything.

    When you go to control panel > user accounts, is the account that you are connected to a "Computer administrator" or "limited account"?

    You need to do some detective work more:

    • In the Startup tab, run msconfig and uncheck ALL items.  If the "RunAs" message does not come to the top, you know that one of these elements is the culprit.  Selectively, double-check items (you can do as a group to save time re-boot) and re-start until you determine what startup item causes the error.  Once you have identified the startup item that is causing the problem, post back with his name and I will try to help you determine what to do about it.
    • The "RunAs" message continues even with all uncontrolled startup items, you going to dig deeper.  Reset things to normal by selecting the option "Normal startup" button and follow the steps.  I'll look at other things that start when Windows starts and see if I can suggest the next steps.

    Photoshop is a pixel based image editing program that is well suited for creating and editing digital images, especially photographs.

    Illustrator is a vector program that is great if you want to create vector graphics based that you can scale up without loss of resolution, for example, a logo.

  • CS4: Better use SSDS?

    I wonder where I will get the best performance for your money shot in a situation of NLE is considering adding an SSD or two to the mixture. The active zone is Vista, but I can switch to faster ponies on a 64-bit machine 7 soon. Doubt there is a difference between the two recommendations, but thought that I will quote just in case.

    First of all, a tangent. On my Premiere Pro CS4 disks, I don't see any indication of 32 / 64-bit versions, but I understand that both are available from the DVD. Can anyone confirm this?

    As for the SSD, the General wisdom for overal performance is used as the boot / system of thrust load app and start training. For NLE, there are other drive considerations that come into play - the disks where the source of the layer to edit footage and the disks that serve as temporary entry/exit in rendering, reading, etc.. There may be other considerations as well, these are just the ones that come immediately to mind.

    I'm less concerned about how much time the computer takes to startup (still standing 24/7) or an application how long takes to load and more focused on performance of Premiere and After Effects then eding, reading and rendering.

    With this in mind, if I bought only a SSD, where would be the best place to serve? And if I threw cards credit and attention to the wind and bought two, where the other would do me the greatest good?

    As always, thanks for the ideas you can offer.

    Chris

    Chris,

    First of all, CS4 is 32-bit only.

    Where you could potentially get the most out of a single SSD depends a lot on your total disk configuration. But my feeling is that the money spent on a single SSD is better used to buy 3 or 4 extra Spinpoint F3 1 TB drives and upgrade your installation. For about the same amount you will get much more storage and better performance.

    No, Windows 7 and Windows 10 require unique product keys and their respective installation files.

    Windows 10 is available as a digital download:

    Buy Windows 10 family/professional edition

    For 5 years, Microsoft made it fairly easy for users of the Windows 7 operating system to get reinstall media. If you have lost your support disc or installation retail collection; either it has been damaged or defective; You can download a copy of the edition that you have licensed from a membership site called Digital River. More recently, Microsoft ended the availability to reinstall media that you can download as a. File ISO in Digital River, which is a digital reproduction of an optical disc.

    It was particularly convenient for people who could not easily get the manufacturer's recovery media, did not want to pay the fees required to get or preferred a clean configuration without the software packaged manufacturers or even a recovery partition does not work. It's easy to use, all you had to do was reinstall and reactivate using the product key located on the certificate of authenticity and download all the drivers on the manufacturers website.

    Given that this option is no longer available, what are your options? See the article for more details:

    How to: What are my options for Windows 7 reinstall media?

  • Error Adobe ID should use "Adobe ID which has not yet been used to allow any other computer"

    I do a few tests and screenshots for my public library right now. After reclassification of ADE 1.7 to 2.0 on an authorized machine, I pressed CTRL + SHIFT + D to Deauthorize. Then I tried to add the exact same Adobe ID to the computer and get this error message.

    "You can allow only this computer with an Adobe ID which has not yet been used to allow any other computer or mobile device. "Please RΘessayer."

    It of weird and contradicts my understanding of the ADE. 1.7, you can use the same Adobe ID on any combination of device (6). This seems to suggest that my ID Adobe must be original whenever it be permitted. My questions are:

    • Does really need to make a new Adobe ID, whenever you use CTRL + SHIFT + D?
    • What happens to contain ebooks DRM on your computer that were related to the Adobe ID who do not accept the ADE 2.0?

    If anyone has any ideas on this, I'd like to hear them.

    N ° you already allowed the computer anonymously, and you can only "upgrade" an anonymous user that has not been used before.

    You can either disable allow anonymous user (and lose all access to the content related to this user), or you can use a brand-new AdobeID which has not been used for electronic books before.

    If you have active anonymously by mistake and not have not any content yet, you want to probably turn off and start again.

  • Which is better: using the NI 9203 or USB Volt to differential entrance map

    Dear all,

    I have 4 pressure transmitters, temperature transmitters 4 with output 0-10 v or 4-20 my. I have also 2 with output 4-20 flow meters my.

    I have two options:

    Is to get all the signals in my and link them to the C two modules NI 9203 or I can get 8 sensors with 0-10 V and then I can use for example NI 6218 where I can connect these signals using differential configuration. While the last two signals (of the two flowmeters) should be converted using components SSC to sell volts so that I can connect them to the same card.

    Which solution is better in regards to signal noise?

    Someone told me that NI 9203 does not support differential configuration, such as the signal of my does not noise like the Volt signal so it does no differential configuration.

    Also, NI 9203 has 0-20 my input range and the output of the sensors is 4-20 my... Is there a problem?

    Please advise...

    Yours,

    Ehab

    Hi Elijah,

    Do you mean that you have the choice between voltage and current transducers and want to know what is the best?

    Current loop 4-20 mA is intrinsically less sensitive to voltage noise.  4-20 my sources have an output impedance much higher that a shunt resistance, so that the vast majority of the noise is deleted in all of the source.  The following application note of the BAPI and our own Developer Zone article both give a good overview of the subject:

    Understand the current loops 4-20 my

    Current measurements: practical Guide

    Regarding the 0-20 mA or 4-20 mA, you will have no problem here.  4-20 mA is commonly used for sensors one reasons are that a 0 can be used to indicate a bad connection (open).

    When you take a measure of the tension, the best way to reduce noise is to measure differently, with your connections made with threads of the shielded twisted pair (Wikipedia link).  The idea here is that any atmospheric noise would affect both the + and - ends of your signal.  Since you measure differently, the noise cancel out.

    You will be probably very well in both cases.  If you use the 6218, you can provide your own external shunt resistors to measure the current, while using other channels to measure the voltage. See the article How to build a system of loop current with isolated M series.  It seems to not be updated for the 6218, but this Council provides isolation recommended for current measurement.

    The 9203 s have this integrated to the Board of Directors and are designed specifically to the measurement current.

    Other recommended reading would be field of wiring and considerations of noise for analog signals.  When setting up this system, you will need to make sure that everything is grounded correctly (without ground-loops, floating connections, etc.).
