• Control the Structure of the event with text file

  I'm new relativaly in LabVIEW (experience only about 2 weeks). I am currently control a stepper motor using a structure of the event. Similar to the sample code given by LIFA, I entered my settings how the engine not move away, then press a button on the windows before, and it works this way. I also have other equipment that works as well in LabVIEW, as a transnational step; all components operate individually.

  Now, I'm trying to make the more automated system and to ensure that all the different equipment work in the same code. So, I tried to implement a structure of the event using a text as an input file to try to control events. The text file has a table 1 d of numbers going down vertically (only the line numbers change). So, I used a table of index function to take the numbers one by one, use a loop (while loop in this example) to go to the bottom of the column of numbers. However, the event not register the change, even if the indicator shows the value is changing.

  Attached, it's my test code and the text file that I use to try to control the structure of the event. Please let me know what I am doing wrong. Thank you.

  Oh, now I understand what you tried to say. I'm using a loop and a case structure to activate different events with the entries in the table. I thought case structures and event were the same, but you taught me the event structures are used just for the façade stuff. Thank you all!

• Programmatically trigger a structure of the event with the value (signaling) is not responding

  Hey, in my attached program I check if the two steps of translation are in a specific position. If Yes, I want my code to execute a sequence of movements. If this isn't the case, I'm asking the user if he wants contributed from this position anyway. It has three options: Yes, go to load (the specific position) and cancel. If he hits Yes, I am using a property of signal value which should update the controls Boolean true, allowing the sequence. Cancellation and work "to load" perfectly fine, but 'Yes' does not work. I think I need a structure of the event to ahndle the value of the Boolean control 'x' change event, however, the addition of this structure of the event for some reason any even do not allow me to click on the Start button of the procedure.
  Thanks for any help in advance.

  Really, you should look into using a State Machine.  You should have really not what happens inside a structure of the event.

  In addition, I would like to use a shift register to store this value instead of a front panel control.

• How to use a structure of the event with a state machine

  
  

  I don't know exactly what you're asking, but it sounds as if you want a bunch of script tests and if the user says stop, to immediately stop the current test and abandon others?  I'll assume you know how to clear the table so that it will not abandon the others, so I guess that you have wrong to abandon the current test?  If it is indeed the case, the problem is that you are not able to spread the message of the VI FP main which is the GUI for the sub vi which is the test where the test may or not have a GUI (FP visible) of its own.  Threading is the first thing to come to mind, but it will be may not need the use of events.

  You can do this by passing a refnum of the stop button to the Subvi, where you can then add to wait to the structure of business event.

  I have attached 2 screws, mainvi.vi which is just a loop displays the number * 2 (number of seconds since the race) to be called subvi.vi and then check to see if the button is pressed.  mainvi.VI is in no way a state engine, it's just a simple loop for demonstration purposes.  subvi.VI just waits 2 seconds and leaves, this is a better engine State structured with an init State to start a case of survey to wait events and an exit status to clean.  You can change everything as you wish so that he can do what you want.  You will notice that even if subvi.vi is running, it will automatically end when you press the stop button.

  I hope this helps.

• Structure of the event with sub-panels

  Hi, I tried to find a simple example with a structure of the event and only two sub-panels.

  I found the 'new Event Handler.vi' and I'm doing something with two sub - vi I did 'Add.vi' and 'Mul.vi '.

  To be able to switch between the two sub-panels used in 'New Event Handler.vi', the programmer used a "time surge" which I can't locate

  anywhere, so I just copied 'new Event Handler.vi '.

  I can't get this to work.

  Take a peek inside the world

  Sincere greetings,

  Lasse

  Hi Lasse,

  Yes, there is. If you open the properties of the subVIs Add.vi and Mul.vi (Ctrl + I), you can change in the tab 'appearance of the window' to that custom... There is an option display front panel, when it is called and the close later while initially closed just sellect them. Then, you will have the effect of 'pop up' :-)

  I slightly changed the example, so that can see them in the form of pop-up windows.

  See you soon

• Can I activate a structure of the event with an another VI control

  I need activate an event structure in a VI with a change of value with an another VI control event. The code is included in the pictures, you can see in this post, and the variable stop is the control that should activate the structure of the event since another VI.

  .

  The code is on other forums of discurssion and is made by Randall Pursley (rpursley8).

• How to manage the structure of the event with two loops

  I have a question about the structure of the user event with 2 buttons?

  key 1: START LOGGING DATA

  key 2: STOP LOGGING DATA

  How do I control my

  structure of the event so that it will work? because now that the loop is save data... I can't stop the loop, when I clicked on buttons.

  the problem with moving it is that I don't have control of the DATA RECORD STARTING?

  Of course, you do.  When you get your press conference button, you say your state machine to move to the State of logging.  You must also make sure that you return to visit the State to wait for the event to check out the events of the stop button.

• Question about the structure of dynamic event

  There is an indicator of "String" and two buttons Boolean ("GenerateMouseDown?" and "GenerateMouseUp?") on the front panel.  If the value of the "GenerateMouseDown?" or "GenerateMouseUp?" control is set to TRUE, the string "GenerateMouseDown" or "GenerateMouseUp" will be added to the indicator "String" once I click on the indicator, otherwise there is no string added to the indicator.

  I created the vi as in the attachment to this post.  However, if I select the button of "GenerateMouseUp?" or "GenerateMouseDown?" as the value FALSE, the matching string still will add to the indicator.

  Is that anybody could be using?  Thank you.

  Hi JCM,.

  It's because you have linked to these events directly to the string ' String: mouse upwards.

  When you want to use the events registered dynamically, you must select instead: "': mouse upward"... "

  You are in no way related to Neo6, who asked a very similar question just yesterday?

• Drag the control example and how to record a value of the indicator?

  Hello world

  I want to drag the Boolean buttons on my front panel in the time of execution, how can I do?

  I remember that I have seen an example or why, it's a map on the front panel, but I don't remember the name TT someone knows?

  and the second question is how to store a value of the indicator, like the first time, you set the value and close the vi and run it again, the value will remain unless you change in the second run time?

  Thanks in advance

  Thanks to you two, are there good examples of mouse followed the structure of the event available?

  and my second question is for example: read a file using the vi, I created the first, that the value of all the positions of the button on the front panel, and the 'get file vi extension' shows the name of the file on the front panel. then I close the vi and open it again, the button positions is always there where they are, but the file name string is empty.

  How can I save the filename so indicator when I opened that vi still once, if not the other position button file selection, the filename indicator still shows the previous name?

• Why not the preferences of the general calendar for "the day ends at:" only offers the possibility of 'am' and not 'pm '? And alerts for an event from 14:00 activate at the right time, but it's at 02:00.

  The "day starts at:" options correctly offer options of "midnight" through time "am" to "noon". Thus the "day ends at:" should have options starting with "midi" and moments of "pm" to "midnight", but instead, they are all time 'am '.

  And alerts for an event from 14:00 activate at the right time, but it's at 02:00. Maybe it's a consequence of the above.

• I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. Help

  I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. HELP PLEASE. previous e-mail files are under mail then mail.earthlink* .net and each of the five mail .net is an email address I have. I can't find a way to identify each file by email to the specific email address (IE mail.my E-mail name.net) so I can copy the files and emails from the past to the email addresses now under tbird. previous installed e-mail identities may not be the current configuration of e-mail files in tbird. I think that I must be sure that mail.name.net matches the previous mail.name.net to be able to copy and paste the old to the new. is there a way to find the file name correct the old email and correspond to the new? all my emails very important information are mostly in the old mail electronic id and must be available in the identification of email again (but same) how can I do this?
