Control an event in a Subvi

• problem with tab structure control and event

  Hello

  My program has a tab control. In each tab, I have an event structure to control some events.

  I encountered some problems. These are:

  1. in each tab, I set tab as an event control, to altogether from the structure of the event as tab change (for example, the image below). My first problem is that when I change the tabs, in the arch depending on whether my program is entered in the next tab environment, happening at the event: change value to main tab! And gives bad result.

  

  

  2 - I've scheduled two final tabs as below in the image. I had no routine in these two tabs. Simply, I want when I change the tab, it goes to the next case of the tab control. But when I run the program, it goes to something as busy after one or two changes tab and did not work properly.

  

  Could someone help me please?

  Thanks in advance

  I want to have 4 tabs, each tab having 3 Boolean control.

  If in each tab all Boolean control wins 1, a Subvi should be run.

  I wrote this code with some time within each tab loop this case hase 3 for each Boolean control. The result is true.

  But I think that if I write it with a structure of the event within each tab instead of 3 cases, the cpu load will be lower.

  Is it not true?

  Make a unique Structure of the event.

  Add events for all controls (buttons, Boolean)

  When the event is triggeredcheck for active tab control and decide what void / vi to run

  It will work fine you

• How to use a structure of the event in a Subvi

  I am using a structure of the event within a Subvi.  The Subvi has a table constructor that built tables and the structure of the event is used so that when the program runs, it allows you to change the elements of the array.  It works, but when I apply within a Subvi, it does not work properly.  This goes into a Subvi, because it will be part of a much larger progrram, so it must be modular.

  If you are using a structure of the event, it is not a Subvi.  If you worry about modularity, you should not use the structure of the event.

  You seem to have a fundamental misunderstanding of modularity.  An event structure must be placed in a while loop.  If you have a while loop in a Subvi, you have transferred control of your program to the Subvi.  You are not at this stage modular.  Your higher level GUI has no control.  You would have to create a stupid system of variables to pass data down to the loop to stop the loop and return to your main VI.  This is not a good design decision.

  Instead of searching for a way to make something broken, you should spend effort trying to understand what you really want to accomplish.  You should also spend some time to learn how to work the event structures.

  This application is small at the moment and it is already on the way to the unreadable.  It's a terrible thing to do for you.  Break these habits now.  variables are only when absolutely necessary.  Using subVIs to accomplish individual tasks, do not run the entire application.  With the structures of the event, use a value of stop button change event for will not be held hostage to the time-out.  If your variable is '2' in it, you're doing something wrong.  It has to be something different between set points, put it in the name.  If you want to make the subVIs, create an icon.

  But first and foremost, invest time in understanding dataflow

• With the help of registration of dynamic events for a Subvi

  Greetings to the forum LV,

  I'm having a problem with the inclusion of dynamic events in a Subvi and hope someone here can help you! Attached, is the culmination of many attempts to try to understand the inclusion of dynamic events. Basically what I'm trying to do with the screw joint is 1.) have a button that controls output PWM, 2). a speed selection menu that can enter 1 button said.) with an array of pwm values predefined; and finally, 3) to have some sort of event program which "connects" controls in 1). (and 2.) (IE, if I move the button to an exact value shown in the table, the speed selection must match this event). So far, I can say with certainty that the "speed selection" event card will not work because "New value" & "Old value" refer now to the refnum and not the selection of speed control (I intend to solve this problem after I solved this problem of the Subvi). However, the map of event engine speed PWM should work (when matches button among the values in the table, the selected speed will also report the "speed selection" control), which allowed me to reach my conclusion that the Subvi is not working.

  My reference to dynamic Subvi Event Registration: http://digital.ni.com/public.nsf/allkb/A882E27D1D7A949386256E0D0066B91A

  You need to make a different State for 'Timeout' in the Subvi and also avoid passing the value of timeout as -1.

  Find the file code.

• Update controls with events

  I'm getting to do a settings editor window that has several groups of settings that can be edited and saved.  The settings are loaded and saved on a Bay of clusters.  The window uses a shift register to store all changes and then you can save at the same time when you are ready.  The problem I see is that if I change a value and leave the cursor in the control, and then a new group he will not read this new value.  I understand that you should put the control that you want to play in the same event, but the problem is I want to be able to read this control with several events and it makes sense to have the control outside the structure of the event.  I have attached a sample vi of what I am trying to accomplish.  I'm relatively new to labview and learning I'm leaving, so any help would be appreciated. Thank you

• Are there any key press\type\hit control textfield event.

  Hello

  I'm counting the number of characters typed in the textfield control.

  I can't find a case where it should trigger and get me counties when I type in the textfield.

  I'm able to count the characters entered using EXIT event. But it gives me an account only when I leave the command or click here and there. While typing in the textfield control his does not work.

  Please suggest me how to count number of characters, when I type in the textfield control.

  Concerning

  Sunil

  If you use the xfa.event.newText, it returns the text that is in the field. So if you use this code on the change event and you type in th estring Test you get

  T, then Te, then, test it

  If you use xfa.event.change, it will give you the unique tank that was typed. So same example above, you will get

  T, then e, then s, then t

  Hope that helps

• Join/leave control room event

  Hello

  What would be the best method to control when a user enters or leaves a piece? I have a base by keeping control over the number of users each of my rooms, and I'm looking to implement a good method to keep up to date because it is very important for my request for data. Are there several apartment possibilities to control everything on the client side? I think that this is not valid because a customer could for example have a connection problem and then it will not be able to send the "I've left the message from the House" on my server. Is it possible for a call from the adobe server to some php on my server function when this happens?

  Thanks for your help!

  Hello

  Go on the client side could be tuned to UserEvent.USER_REMOVE event of UserManager. This is returned when the item the user gets are returned from the server.

  We use mainly that for all accounting side of customer to userlists.

  However, using the API server to your server can listen to the UserManager Collection after calling registerhook and subscribed to UserManager Collection. There is an example of php in sampleApps for your server record hook and listening to a node of the collection as UserManager.

  Thank you

• Control the event with two controls

  Here's what I have.

  I have two separate loops of time. Inside of each timed loop, I have a structure of the event. Each structure is the trigger by pressing a button each. It works very well.

  However, I would like to add a third button that runs the two structures of the event. I want to do this without creating additional events in each structure. Is it possible to somehow this third button wire to the other two and to trigger both based on the action of the third? I have problems it works.

  Thank you

• Event ID 11 ATAPI / Service Control Manager event ID 7031 / crashes / freezes...

  OK, I'm almost certain that it is a hardware problem; probably in the hard drive (because that's what I read form similar problems online).

  I have a Dell XPS m1330 laptop computer, 2 GB of Ram, Vista Home Premium, 2.2 GHz processor, Nvidia G8400 MS with 128 MB allocated.

  Basically, he started a week or two ago, I got bluescreen containing "KERNEL_INPAGE_DATA_ERROR", out of the blue. I read it can be caused by incompatible software, which makes sense to me because I have recenty changed in msconfig startup programs, to try to speed up my startup... It was fine for a day or two, but then I got persistent crashes, woulf computer freeze for 20 seconds - 3 minutes (90% of the time when I was using firefox, although he did so with just iTunes open by himself before).

  Checking event viewer I've seen above, errors with the Red 'X'.

  I also see a lot of "Volmgr - the system does not have empty data in the transaction log.". Corruption can occur "with a yellow '! ».

  Also, I see some "Kernel-processor-Power - the speed of the processor 0 is restricted by the system firmware. The processor has been in this state of reduced performance for 9 seconds since the last report. »

  I often get warning messages that various programs have stopped working and the dialog box "do you want to close now or wait to face." These programs are sometimes an indexer Board/management console/windows search service Mcafee etc...

  Today, I got a new problem, a warning box appears, saying a critical error has occurred and windows will restart in one minute, telling me to save and close all work immediately...

  The only reason why I post here instead of replacing parts is that I updated my Dell Support Center and ran a test of the hard drive:

  Targeted reading test
  Test started		03/05/2011 12:37:29
  Error message:	Error reading sector 23962699.	03/05/2011 12:38:14
  Error message:	Error reading sector 23962698.	03/05/2011 12:38:58
  Error message:	The test found 2 errors in sector.	03/05/2011 12:39:01
  Completion test:	Failed	03/05/2011 12:39:02

  For some reason, it won't test the rest of the hard drive, just do not here and stop the test. However, he claims that the mistakes above are not "allways" indicative of hard drive failure... and annoyingly, tells me to do more tests...

  I know this doesn't look good, and I am extremely optimistic to think I can remedy without replacement of the equipment, but are there steps I can take before finally diving into the portfolio? (Guarantee missed 3 weeks ago... obviously).

  ChkDsk runs fine, no problem.
  Reference Dell Diagnostic returned failures in the hard drive, which I can list if necessary.
  I checked for new drivers, nothing there.
  I took out my hard drive, compressed air used to attempt to clean the connectors, nothing helps. (Note I've heard SATA cables may be at fault, but I wasn't able to get to them because of their location, migt need to disassemble my laptop further if you think it's worth)
  Off the CD/DVD rom drive (had mistakes occasional cdrom with yellow "!") The computer can will work perfectly for hours and then suddenly hang down to the minute, and Event Viewer is filled with dozens of error ID 11 atapi...

  Any advice?... huh.

• Control billing events in project invoices

  Dear Dina,
  
  When several project events are created in the system even date and the end user wishes to restrict the events to go to specific bills, how can it limit? in GDI, the system generates automatically 1 new invoice with all available existing events.
  
  Kindly help me how to overcome this kind of situation.

• Digital control do not light the Subvi table lines

  Hello people of the forum NOR!

  I have a small question, I think you could help me:

  I tried to find a way that would allow my program read data, acquired from a millimeter and use a table - with coefficients - multiply the data obtained.

  When it was written directly on my program, it worked fine, but when I created a sub VI to 'clean up', he ceased to alternate values and it uses the fixed value of the Sub VI.

  The sub VI has a connector to the CNC.

  This program is the 'read the table under vi' attached to this message and the other, is the program I use to get my data.

  Thank you before useful assistance.

  Concerning

  Leandro

  Hello Leandro, Dennis

  I don't think I got the problem right so I can only guess:

  VI Sub is placed outside the Structure of sequence and therefore only runs once at the beginning of the VI.

  As Dennismentioned, since the "Table" does not have default values assigned it cant work now.

  It would be better if you post an another Set of screws: (Bevore, adding the Sub VI and after)
