change of State and change read Boolean

Hello everyone,

Sorry to bother you, but as a new user of Labview, I always have problems to the VI program. I try to do my best alone, but right now I'm at an impasse for some time... That's why I come back to you.

Here's my problem:

-in A VI I made, I have a Boolean value which controls than if the data are recorded or not. When recording is activated, the led lights up, when off the light is.

-Actually, I bind the Save action to something more complicated:, I wish that the State changing the Boolean value to light several leds in a specific order.

Thus, when the Boolean value changes, this should change the status of the leds.

I managed to do it, when you press the button in the boolean_count.VI, which has for result that I would get.

My problem is that the state change is not triggered by a push button. It depends on several State (true or false), which the record command or not.

To simulate this, I tried to do the same as above, but with 2 Boolean values, which must be both faithful to initiate a change. I tried to do this in the Try_out_boolean.VI file

But iin this file, when I push my buttons, there is no change of State in the right part of my Panel of...

I hope you can underrstand what I mean. If you have any suggestions, I'll be happy to read them.

in the property node "1and2" of your Try_out_boolean.vi, you read the property "BindingLEDVisible".

(as I downloaded) That makes no sense at all.

-> Click on with the mouse on the node of this property one choosing the property "Value" instead.

Then, your application must react as wanted.

Thre may be other possible improvements, for example using the event structures instead of constantly of the poll.

but that's another topic...

I hope that this help a little.

    It seems that your ID Adobe was initially registered in Pakistan due to which it is not allowing you to make purchases in the United States.

    You can create a new Adobe ID, register in the United States and then it should allow you to make a purchase.

  • Change control Boolean façade of round instead

    I would change a Boolean control of the façade of a square round LED LED programmatically at run time.  I guess I can do that with one of the nodes invoke or property, but I don't know which.  How can I do this?  Thank you!

    As much as I know, that you can not. I think that the property ID of Style seems to indicate that information, but it is a read-only property.

    Variation: use two controls, one round and one square and hide/show you want.

    EDIT: I see Lynn has already suggested on two controls while I was writing my response.

  • TCP speed problem when changing read write

    Hi all

    I have a weird problem with TCP/IP blocks in labview. I'll take a moment to explain my set up.

    I have a laptop running Labview 7.1 and a machine of RT ETS running standard Labview RT software. Both are linked to an Ethernet dedicated, not a crossover, but through a network switch which turned nothing else on it.

    I have 2 screws, a vi server that is running on the machine of RT and a vi client that runs on the laptop. All this doing is to transfer a small amount of data back. The client sends to the server a DBL vi, this number is multiplied by 3, has 1 added to it, and then send again. The client then sends a string to the server, followed by a byte of stop. (see attachment).

    What I find is that this loop at the incredibly slow pace of ~ 200ms. It is a 100 Mbps ethernet connection! I tried many things and cannot work out why and I hope someone can help me. It seems that there is some delay when the direction of data is changed (i.e. a read after a write)

    This is where it gets ridiculous. When I remove the sending station and stop as Boolean of two screws, it works very, very quickly.

    This is part of a project more vast and complex, I have a problem with and I narrowed down it to this issue. I checked the boards and nobody else seems to have this problem, which would suggest that I do something stupid

    Help, please!

    We assume you want a pulse when clicked on a button on front of (boolean).

    I don't always know just what he's wanted.

    You want a single pulse when x is greater than 4?

    You don't need a structure for this event.

  • Can an edit button in another State and stay there and navigate to a URL?

    Hi-

    I've been trying my brain and scouring the internet since yesterday to find a solution to this... It seems pretty easy, but I'm at a loss... maybe I'm over thinking that it and it is simply not possible?

    We have a button that we want to, when you click it, change to another State, to remainand also use a navto to go to another page in the publication... is it possible?

    We tried to double the action of the button, with fake buttons, etc. all this without success. What we now have is... You can type in navto and the button changes, but right now between the button is released and actually jump to the page, we want to go to, it returns to its previous state.

    The only explanation I came up with is based on the information on this page: http://help.Adobe.com/en_US/digitalpubsuite/using/WS67cb9e293e2f1f60-8ad81e812b10bfd837-80 00.primeras html -because I want to accomplish two actions fall into two different categories: support for the actions of the buttons of hyperlink and sustained actions for the slide show buttons, that is simply not possible?

    Your help is greatly appreciated!

    Thank you

    No, which is not supported with several actions. Impossible to move from one State and then jump to another document.

  • Display States and custom components

    Hello

    I use a stack view for this application and once the user is logged on to the application that they see this "Home Page" that contains essentially two components as follows:

    It is in my file "AppMain.mxml".

    < mx:ViewStack id = "appView" height = "100%" width = "100%" >
    < mx:Canvas id = "Home" >
    < view: TeacherList id = "teacherList" / >
    < view: StudentList id = "studentList" / >
    < mx: / canvas >
    < / mx:ViewState >

    So in my TeachList.mxml file I have this < mx:ButtonBar > and one of the buttons is 'Add teachers', when this button is clicked, I want to hide the component StudentList using view States and finally display a form for the user on the same screen, so they can add a teacher. If all the code is in a single file, I think I could do it myself.

    I tried to put the tag < mx: states > in the file AppMain.mxml, but given that the < mx:ButtonBar > mxml code was inside a different file, that he did not see the block < mx: states > I added in the file 'AppMain.mxml '. So I then tried to put the block < mx: states > in the same file as < mx:ButtonBar > reality but then how do I access the id of the component (studentList) so I can hide

    Any help much appreciated.

    -Westside

    Yes - you have to control the use of custom events.

    Let me to pseudo code it for you - you'll have to maybe a little research yourself

    (1) create a State which removes the student list and displays the component that you want to display (I'll call it 'state2' for now).

    (2) in your teacherlist component, create the event, something like this:

    [Event (name = "customEventNameHere" type = "flash.events.Event")]

    (3) in your teacherList component dispatches the event:
    public function buttonClickHandler (): void {}
    var eventObj:Event = new Event ("customEventNameHere");
    dispatchEvent (eventObj);
    }

    Call this function when the user presses the special touch in your teacherList component.

    (4) manage the result. Using Flex Builder? If Yes, when you press the space bar on your call to the teacherList component, you will see the "customEventNameHere" event available.

    (5) change of State:
    public void changeTheState(eventObj:Event):void {}
    currentState = 'state2 ';
    }

    I hope that the work - please post back with your results (or mark replied if you get)

    See you soon,.

  • Windows Control Panel has stopped working and cannot read the CD

    Original title: windows control panel has stopped working

    When I went to install my Rosetta Stone program it showed Windows has stopped working and then installed the program and when I put the cd in my computer saids windows control panel has stopped working and cannot read the cd

    Hello

    You say "Control Panel has stopped working" or "Windows Explorer has stopped working"?

    Follow the steps mentioned in the article below and check if that helps:

    Start the computer in a clean boot state

    Start your computer in a clean boot state, and check if your computer is able to read the CD. Start your computer in a clean boot state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

    See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    http://support.Microsoft.com/kb/929135

    Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

  • Interrupted SQL statement and start several times with several SQL_EXEC_ID

    Hi all

    We meet a strange phenomenon, maybe someone can help.

    We see that sometimes, when our client runs a single statement, implemented Oracle to process the statement with a special SQL_EXEC_ID, but after a while stops and starts processing the statement along with different SQL_EXEC_ID. Then, after a while, it happens again - stop Oracle processes the statement and start from the beginning with the new SQL_EXEC_ID. This happens again and again until we kill all of the other sessions on the database (then it ends).

    What we see exactly: Client executes the statement (sql_id = "2tp7pz6yv87qp"). Monitor us v $ SQL_MONITOR and get this:

    SELECT Sql_id, sql_exec_id, to_char (SQL_EXEC_START, "HH24:MI:SS MON-DD-YYYY) SQL_EXEC_START, status OF V$ SQL_MONITOR where sql_id = '2tp7pz6yv87qp' ORDER BY SQL_EXEC_START DESC;

    2tp7pz6yv87qp 16777216 28 may 2015 07:19:14 the EXECUTION

    After a while check us again and see this:

    2tp7pz6yv87qp 16777217 28 may 2015 07:36:17 the EXECUTION

    2tp7pz6yv87qp 16777216 28 may 2015 07:19:14 FACT

    After a while, we see this:

    2tp7pz6yv87qp 16777219 28 may 2015 08:09:58 the EXECUTION

    2tp7pz6yv87qp 16777218 28 may 2015 07:53:37 FACT

    2tp7pz6yv87qp 16777217 28 may 2015 07:36:17 FACT

    2tp7pz6yv87qp 16777216 28 may 2015 07:19:14 FACT

    and so on — will happen again and again until we kill all of the other sessions in the database.

    When comparing the follow-up of the different SQL_EXEC_IDs SQL reports, we see that each of them did exactly the same job: used the same execution plan, beginning treatment she even read/wrote the same amount of e/s and each of them stopped at the same point during execution. You can see that for each SQL_EXEC_ID execution 'stops' in the middle and never reach the end of the plan. She always stops in the JOIN by HASH and never continue to the next steps in the implementation plan.

    When you look more deeply, we see in V$ ACTIVE_SESSION_HISTORY always last thing that happens for every SQL_EXEC_ID is HASH JOIN RIGHT OUTER (SQL_PLAN_OPERATION = HASH and SQL_PLAN_OPTIONS = RIGHT OUTER JOIN). Then comes the new SQL_EXEC_ID and it starts to do the same thing as the previous SQL_EXEC_ID did when it was launched.

    Kill all other sessions, run finally ends. We see that the final (successful) SQL_EXEC_ID work and completes his plan to run to completion.

    When executing the same single statement (when it comes to the single session in the database), it ends with a single SQL_EXEC_ID. Its SQL monitoring report looks like the final execution when the phenomenon occurs after killing all other sessions.

    -We checked that the customer executing the query only once. AWR also only shows simple execution of the query.

    -We have reproduced in many different clients (plus SQL, JDBC thin client OIC and DBMS_SCHEDULER job).

    -It has no PARALLEL in the query or table.

    -In this case for different statements (different INSERT-SELECT and MERGE instructions).

    -Version: Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

    Does anyone have an idea?

    Finally found the root cause of the problem.

    This phenomenon occurs when the cursor of the active query being invalidated. This can occur in several scenarios, in our case, what happens when we work on a single partition (read or write) and perform DDL operations on different partitions of the same or the tables.

    Steps to reproduce:

    1 launch long command DML that affect the single partition

    2. in the course of executing this SQL, do one of the following values in a session different all 1 minute:

    2.1 do the indexes to a different partition unusable: ALTER TABLE X EDIT PARTITION Y UNUSABLE LOCAL INDEX

    2.2 rebuild the unusable index of different partition: ALTER TABLE X EDIT PARTITION Y REBUILD UNUSABLE LOCAL INDEX

    2.3 a partition different truncate

    Support of Oracle we were told that this problem is known and there are several requests for bugs and improvements thereon, for example this one:

    Bug 12905327 : TRUNCATE to an INVALID PARTITION TABLE UNNECESSARILY IMMEDIATELY all THE SLIDERS

    In our case (ETL process), we used to perform all these operations DDL and DML operations long (we work on different partitions in parallel). In order to solve, we have separated these operations to the different phases in our process and don't be DDL and DML operations at the same time more. This solved the problem for us.
