I mean other dots like the coercion dot that can appear when we connect an input to a VI. Sorry, I'm not sure if I am clear because of my poor level in English!

Thanks JFM. And do you know about other dots?

Hi all, I have a question concerning the inputs in Labview. Yesterday, I wanted to change an input format from a decimal representation to an hexadecimal one. Then a grey triangle appears on the input of the VI used (see attached file below) I have seen on this forum that it has a meaning but I can't find where anymore! :headbang: Can someone help me ?? Thanks in advance!! CocoWK

thanks a lot for this help... I'm not sure to have understood all, but I'll come back here if it's necessary

Hi everybody! I need to open another VI from my main application (in order to group settings and other parameters).. To describe my application: I want a main window composed with my main VI interface. Before the user launches the tests (because my application consists in multiple tests), I want to open another window, which is another VI that contains all the parameters for the tests. When the user closes it, I want to get all the settings to import them into my main VI. Is it possible? Can someone help me? Thanks in advance Coco

Yes I know that it is better to link directly to the terminal, but it's not possible in my case. That's why I asked the question :laugh: Thanks for all your advices. I didn't have the idea of testing this way... coco

Hi! I am beginner with LV. I want to know the difference between a "Value" Property Node of an indicator (integer, double or other) and a local variable pointing on this same indicator. Is there a difference in terms of performance?? Is there one solution to prefer??

Thank you for your answer. It's not exactly what I wanted to do. I want the measurements to be done continuously that's why I put a while loop and not a for loop. But perhaps is it impossible. Your answer helped me, and I will work on it to try to get what I want. Thank you.

Hi everybody, Sorry for my poor English, I'm a french student in internship using Labview for the first time. I want to simulate a random binary frame. I found functions in Labview that can generate sine waveforms and square waveforms but using a periode. In my case, I want this signal to be square and to represent for example a binary sequence measured on a bus line such as CAN bus. Is there a vi in Labview that realise this? Or do we have to generate this signal ourselves? Then, here is my problem: I made a vi that generate this type of signal, and I wanted to measure the signal pulse width and its rising and falling times. But I get an error message like "Amplitude of the signal is 0"... I join the VI to this message for you to see my errors... Thanks Download File:post-4586-1144395131.vi

Problem using "Two Button Dialog"

Thank you for your advice. My VI runs correctly now. Thanks See you Coco -
Problem using "Two Button Dialog"
cocowk replied to Aitor Solar's topic in Application Design & Architecture
Ok thanks.. I thought it was possible because of my sequence structure.. So, if I understand, if I put a stacked sequence diagram, and place a event struture in the first part of the sequence, this event struture will be active for all the sequences of the sequence diagram? -
Problem using "Two Button Dialog"

ok thanks.. here are the main vi and its sub vis. -
Hi everybody, Sorry for my poor English, I'm a french student in internship. I don't master Labview. I have a problem using the "Two Button Dialog". I need to design an application to verify hardware specifications. What I want to do, is to prevent the user from stopping the VI before the end of the process: I want him to confirm that he wants to stop the VI. So for example, I have two buttons: the first one is used to Close Labview, the second is used to Stop the VI. I have added two Button Dialog with different messages to manage the differents cases. When I execute the VI, the messages appears and when I click "Ok" to confirm the stopping or closing of Labview, it works. The problem is when I click on "Cancel". The dialog box is closed, and the VI seems to continue working but the User Interface is blocked. I can't click on the buttons or modify a value anymore... There is a sequence diagram with a while loop in. In the while loop, i have an event struture. It is in this event structure that are managed the click events. Thanks for your help. Coco
