LabVIEW: start button XControl

[@samuellozadahuitzil7271]

Hey it has passed several years since the publication of this video but actually you´ve helped me a lot,

[@LabVIEWtricks]

+Samuel Lozada Huitzil Great!

[@ИльяПолетаев-ч2р]

Man, that was realy usefull and understandable lesson, thank you

[@marvin117]

Thanks. It worked for me. Clear and concise.

[@krishnadivya5236]

Hi, this videos was helpful to create the start control for the vi. Can we also create stop control in the simliar way for the complete VI. I tried it in the similar way with little changes but I failed. Could you please help me on that.

[@jaromonkey]

Hi, I have a problem with your trick. I've created start button according your instruction, It starts vi as it should but seems like it takes over whole thread, within which is a slider, stop button etc. execution of vi interior is OK but i can't do anything in front pannel. Do you have idea what could be wrong?

[@LabVIEWtricks]

Did you see the note I added about connecting the inputs of the "Run VI" method? For some inexplicable reason, the XControl doesn't work anymore if the inputs aren't connected.

[@chaimaakremi2054]

5:47 here at the "wait until done" you should creat a constant and sit it as "false"

@@chaimaakremi2054 Thank you very much, I have the same problem and your advise works for me.

[@adrianmedina7175]

@chaimaakremi2054 thanks so much your advice helped me

[@恰同学少年]

simple yet very useful,thx a lot!

[@BloodstarDE]

In what Situation is that useful? I guess there are much better usages for xcontrols

[@ithinkthat6609]

Hi, thanks for your tutorial. Can you explain me why you modified the section 2 (Dispaly) of Case Structure ? I realize that your X Control works without modifying this section :)

[@LabVIEWtricks]

+IThinkThat It's just a convenience. Controls will show their label by default. This way the label is automatically hidden.

[@ithinkthat6609]

+LabVIEW Tricks I got it, thanks a lot !

[@gerardga1108]

how i get it ?

[@aminrasoulof8349]

Very helpful. Thanks!

[@Asifiqbal138]

how can i open step 7 software from labview front panel?

[@LabVIEWtricks]

What do you mean? You have to be more specific.

[@Asifiqbal138]

LabVIEW Tricks can I open any other applications from labview Front panel by just clicking one button like PDF file.

[@LabVIEWtricks]

I think so. You can always run command line scripts, if nothing else.

[@divyang38]

can u please do it for continuous run button using same Xcontrol..

[@LabVIEWtricks]

Unfortunately, there's no way that I know of to access the Run Continuously button. If you absolutely need this functionality, the best I can think of is to have the start button start a subvi asynchronously that monitors your main vi, and have it run your vi again when it goes idle. Then you need a stop button xcontrol that stops the subvi. That solution is obviously very costly and quite impractical.

[@divyang38]

thanks for reply.......... anyway i m getting extra marks for my project from this start button thanks alot dude.. god bless u................. :) if it is possible den please upload video for continuous run button.., m also thinking on dat.. if i will get some solution den i will tell u.. keep watching all of yours video ... really nice work..

[@LabVIEWtricks]

Divyang Patel Thank you! I don't know how useful a cont. run tutorial will be, plus there are a bunch of other tutorials I want to make first. We'll have to see. If you find something out, please tell.

[@gerardga1108]

hello I try to do the same for my project but I cant find XControl!!!!!!

[@LabVIEWtricks]

File -> New... -> Other Files -> XControl

[@giuliarobustelli3265]

In Other Files i don't see XControl. Where can I find it?

[@adrianmedina7175]

Thanks so much for your trick

[@ernestorafaelzapaaviles2673]

GRACIAS DE COLOMBIA

[@randulajayaneththi6309]

[@hanhduc1659]

thanks , you help me solve the problem with start button

[@xovinia]

thank you was very helpful for me!

[@alexgu8745]

Thank you so much

[@natalieweissgerber]

Hi, i have the same problem encountered by juanarash1. When i press the start button, i cant press my stop button in the while loop. it works when i run it normally. any idea why this happen?

[@LabVIEWtricks]

Is the stop button inside the while loop?

[@natalieweissgerber]

LabVIEW Tricks yes. In oder to stop the while loop that is why it is inside.

[@LabVIEWtricks]

Bibi Bibi Found it. The "Run VI" method requires the inputs to be wired. Right click on the connectors for "Wait Until Done" and "Auto Dispose Ref" and choose "Create" -> "Constant". Dunno if this is a new bug, haven't noticed it before.

[@natalieweissgerber]

LabVIEW Tricks Thank you. I just tried it. It is working, when both constants are false. :) Thank you for noticing it now. :)

[@LabVIEWtricks]

Great! Glad I could help.

[@juanarash1]

I have followed your steps but get broken xcontrol!

[@LabVIEWtricks]

Tinkering with xcontrols easily break them, and then you have to start over. If you like, can you PM me the error message?

[@juanarash1]

LabVIEW Tricks I found the reason. When adding new event for the button, the wiring for Data in and Display state were not done. Any way I got new problem. In my program I have just a while loop and using start button causing that loop stop button does not work. But when running VI normally it works. Thanks alot dude. I was thinking to do it for about two weeks

[@LabVIEWtricks]

juanarash1 Sorry for the late answer. Did you put the stop button inside the loop?

[@divyang38]

veryyy helpfull
