Global VI on the low level does not change from front panel indicator

I attributed to a global variable (CMM_SN_Global 3.vi) to a value in a Subvi two levels down from the façade. When I run the VI of Panel before a flag set by the overall does not change even if the global variable is assigned the correct value until later in the program. Shouldn't be an indicator on the Panel before the value assigned to the global as soon as the world is assigned a value. Or is it not true?

Thank you.

Hi Chuck,

If you asked for examples:

What we have here:

-the select node with these 3 Boolean constants is really absurd (aka RubeGoldberg) the output is always TRUE!

-l' 'position' indicator belongs outside the case statement, any write on this indicator ("unnecessary local"!)

-Why is there an additional wait inside the case? Do you really need that as you expect in the while loop?

-It is not recommended to compare floats for equality - as you do here with the structure of your case when wire you a DBL to the input switch. Why not convert the data itself in full to be on the safe side?

Then you say: "my plan is to have ten independent loops like the top.

This is the reason for using subvis. You can have as many loops as you want, but only need to code once the algorithm ("duplicate code").

More comments on why I recommend some "realignment"?

  • I can't tp perform actions on email or some Web sites because the pointer does not change from a helping hand on all orders at the top of a page - any more down works fine

    In Hotmail, for example, I can open any message in the Inbox except the top one, but then I am unable to answer or to take further action because the symbol of the pointer does not change from a helping hand and clicking on has no effect.

    If I try to open the top message from the page by clicking on the command "Open" is gray.

  • SSRS 2008 SP4 - header or footer of the report contains the dynamic image does not change

    Hello

    Our version of Reporting SERVICES to current production is 2008 (not R2). And we have the problem that the header or footer of the report contains the dynamic image does not change accordingly.

    According to this hotfix, the problem has been resolved in the last SP R2 and we tested, it works.

    https://support.Microsoft.com/en-us/KB/2563216

    So we applied the latest SP to SQL Server 2008, however, the problem persists.

    However, we do not expect to upgrade the SQL Server 2008 to 2008 R2 for the moment.

    Guys have faced the same problem before and has an idea how to solve this problem on SSRS 2008 or any workaround?

    Thank you

Removal and installation of new but certainly not it's always the same thing with the default name which is «WebWorks app» What is the problem? I couldn't change it.

    Thank you.

    Hello

    It is a known issue with version beta. The name and the icon is changed in the file of the bar, but persists on the device. If you have to deploy the same file on another device appears the correct name.

    The solution is to change the code of the widget as well.

    This will be fixed in the Gold release.

  • Satellite A300-17N - the CPU multiplier does not change under load

    Hello

    I have Toshiba Satellite A300-17N. Yesterday, I noticed that my CPU does not change its multiplier under load.
    I have used programs like premium 95 and Orthos CPU load and programs such as CPU - Z and Everest.

    The multiplier blocked on 6 and do not change its value.
    Under load the multiplier should change its value to 13, but it didn't happen.

    In this case my CPU works on 798 MHz (133 x 6) 1732 MHz (13 x 133) instead.
    I will be grateful for any advice.

    Hey Buddy

    I put t know what you are talking about, and I don t know if you're up-to-date on CPU technology but the laptop was equipped with the Intel Pentium Dual - Core T2370 processor.
    I recommend the Intel page on Intel Dual-Core T2370 properties.

    This processor supports Enhanced Intel SpeedStep technology.
    Do you know what it is?

    Here is a short info from the Intel page:

    + Enhanced Intel SpeedStep technology allows the system to dynamically adjust the frequency of voltage and core processor, which can translate into a reduction in average energy and decreases heat production average. +

    I think it should be clear now.

  • Button value change records in the structure of the event, but does not change appeaance?

    Hello world

    A quick question... I hope someone can answer...

    I have a code that uses a PS button within a structure of event to trigger a signal of AO... My code is below. The code works fine and the OD goes off when you press the button E-Stim... But when pushed the button does not change with reliability the appearance (i.e. of the gray 'off' red 'on' color)... Sometimes color changes; no other time not... If I remove the structure of the event and the survey button in the appearance changes as expected.

    What is going on? I would like the button to change the colors on the user interface to indicate that it works... Should I programmatically control the color?

    Kind regards

    Jack

    I guess that when query you the button you have some delay in your loop? Locking means that the button will change its value when you press it, then switch back to the original value once the value of the control has been used by the code. When you ask, this means that until he reaches the next iteration of the loop, but in the case where the structure that will happen immediately.

    The default setting for the buttons to modify its behavior as in most of the application would be latch releasing. You then raise the event when the button of the mouse over the control. This also allows "drag" control if you push down on the subject, given that you do not release control in this case.

    change on the footer file in the library and download it, it does not change on the site. Is there more than that? Thank you!

    You update the library item, then locally update all the pages that contain this element of the library and then download all the modified pages (that work)?

  • structure of the event recorded does not change value

    I have a VI that communicates with an FPGA via a telnet interface.  I have several Boolean controls on the front panel.  When you click a control, it sends a write command on the face i in telnet to the FPGA.  Similarly, if a process in the FPGA himself wrote the same registry (that control written when I clicked on it), an order is generated in the FPGA and returned to the VI and the control (via a local variable) lights or unlights accordingly (based on value).  In other words, these controls are read-write...

    It's all workers, except for one important thing.  I have the code that runs through a structure of event whenever the value of the control changes.  I can see that this code executes in fact when I click on the control via the front panel.  HOWEVER - when something is generated in the FPGA finally changes the value of the control, the structure of the event does not, even if I see the value of the change of control on my front.

    A specific example, I have a control named CLIENT_LB.  When I click on CLIENT_LB, I see it lights up, and I see the event structure code run.  Now, if I have the FPGA process to set CLIENT_LB to 0, I see unlight on my front, but does not run the code structure of the event.  I have probes in place who have checked the associated local variable CLIENT_LB evolving impact of values.  The structure of the event reads: 'CLIENT_LB': value change.

    Shouldn't an event structure "value change" run when the value changes, regardless of whether if it happened manually (i.e. me by clicking on the control) or automatically (i.e. the FPGA written in VI and changes the value of the control)?

    The VI is great, and you would not be able to test it in any case unrelated to the material, to remedy that I've attached 2 screenshots, I have described below.

    1. This is where the string from the FPGA analysis occurs.  The chain between the sub - VI, and then the data chain part is hidden to determine if the Boolean value of the control is true or false.  I put a probe on CLIENT_LB, and I see that as the FPGA changes the value of the register, CLIENT_LB passes from false to true as a result.  I checked this several times.

    2. it is the structure of the event.  This code runs when I click on CLIENT_LB on my face, but does not run when the peak CLIENT_LB #1 local variable is changed.

    Writing to variables never fires events to "change the value. If writing should raise this event, use the property "Value (follow the signs).

  • When I change the main mxml file in the project and then export the swf file does not change, why?

    I have an existing project, years ago that I need to change, I am using Flash Builder 4. When I export the project, it creates a SWF in bin-release, then when I change the code in the mxml project file or files of any format and export the swf file needs to change, but it's not. You have an idea why this might happen?

    Thank you

    I found the problem, there was a SWF into the html-template folder within the project. This has led to substitute the swf of the new generation.

  • Why the file size does not change when I use "Process multiple Images" to add a watermark?

    Hello

    I use 11 elements. To add a watermark to a lot of JPG photos at the same time, I use the function 'process multiple files.

    I select a source folder and a destination folder and adds a number to three numbers for each file. I do NOT check the box marked 'change photo size. After that, I set the watermark I want printed on my photos and hit OK. All files in the source folder are processed and saved with a new name in the destination folder. Loyally.

    But. The file size of the new file is strongly reduced, compared to the original. He's going from 10 MB to 500 KB (in general). Why is this? Is there a way I can help?

    Kind regards

    File size reduction is the effect of jpeg compression. In the process several files dialog, check the bottom option "convert files to the format" and choose "jpeg max quality.

  • DNG files exported from the LR4 showing does not changes made when opened in PSE10?

    I have LR4, and once I do some changes that I exported the files I want to use DNG.  Then I open them in PSE10 to make final changes.  It has been working well, in fact I had an old version of Adobe Raw in my PSE on my other computer.  Then when I opened to post-secondary studies, he would ask if I wanted to convert to compatible version for editing in camera raw.  I always says no b/c I have has no need to do more raw edits.  Now that I've installed PSE on my new computer, it has the new version of ACR I guess.  When I open the DNG Edit now I no longer have this error message, but it's to show my contrast, etc. as an action setting raw instead of the changes I made in LR.  Some are like vibrance, but "recovery" that I know is "strong points" in LR, and other things are not displayed correctly.  I know that the options are different, but I don't want to use the ACR settings he uses when I open the file, or have to go through them again.  I'm not there is something I'm missing, but he cannot know.  Thanks for any help!

    There is zero advantage to sending files DNG at the PSE. As you can see, you're not see your changes and get different sliders in PSE, and indicates that certain types of ACR version mismatch. And since you say you are done making the FIRST changes, this wastes just opening time of the DNG in the PSE/ACR interface that you will not use...

    Rather than send the DNG PES files, send a TIF file to PSE using the command of Lightroom Photo-> change, and this TIF will open directly in the editor, with all of your changes from Lightroom intact PSE.
