I HAVE A DREAM

Hi,

thank you for your answer. 

@MarkCG do you suggest me to use the matlab code in Labview ? 

I have read about it and it seem to be use for echo cancelation.

@Jordan Kuehn I have a similar question. The context is: I will like to estimate the time of apparition of and ultrasonic echo. 

I have used elements of your snippet. The "get a wave form subset" give a subset in a different timetable independent of the timetable of the main waveform, I could use it if it maintain the timetable of the main waveform.

the "seach waveform" search a given value and return the index I think. Any recomendation please ?

Hello

I have simulated and ultrasonic wave and want to estimate the echo apparition by getting the pics and valleys and giving the time of apparition of a meaningfull pic of my echo. which itself represent the time of flight. knowing the time associated to my pics is my question.

Thank you very much for any Help!

Hello I am implementing a Time of Flight analysis for ultrasonic waves.

My Vi return me error 01 when I press "Get A-Scan". How can I correct it ?

The scénario ist quite simple: 

- I should simulate an ultrasonic wave(ref. Pictures) so that 

-the user could call/display the differents Ultrasonic Scan(A-scan, B-Scan, C-Scan, etc)

-The User should be able to estimate the time of flight.

Time of flight definition:  (TOF) describes a variety of methods that measure the time that it takes for an object, particle or acoustic, electromagnetic or other waves to travel a distance through a medium. Short, the estimated time between the input impulse and the reflected impulse.

I got inspired by the LabVIEW Ultrasonic Starter-kit.

PS: don't hesitate to make me any remarques. We learn by making mistakes.

Welcooooooooooooooooooooooome  

let check this. Thank you

Hello

I recently started learning Labview and I just got my CLAD.

My special thanks goes to Hooovahh and all the community

Yeaaaaaaaaaaaaaaaah

Thank you

Hello  

How can I put a picture in the background of a Path control, so that a the run time the user could have a meaningful suggestion of the use of the control ?

Thank you

I understand hoovahh . And thank you for the link. 

Ok Jordan I get You

Ah Ok, I see  

Yes I am. This is great. Thank You hooovahh

Hello dears ! I would like to award a symbol to each dropped items in a listbox. how could I arrange that each dropped items get a own symbol. Thank you. 

Thank you

No I don't have lots of experiences with Forums. Thank you Hooovahh.

I don't know why asking questions should be mocked mister Jordan Kuehn and thank you for your attitude. 

I thank anybody who support all of us willing to learn more about this passionating language.

I am hier to enjoy it, nothing else.

Thank you very much Hoovah

Where is the place on the Home page where to explicitely make a thread ?

Hello

please, how can I count the éléments of a listbox ?

Hello ThomasGutzler, ah thank you I see

 here is the idea of my UI design pictured. 

I would like to implement a user interface where the user can drag and drop files from window explorer and process it.  But I don't really know how to start. I know the basics. I have try to use list box but what I want is a sort of  MOVIE MAKER for files. Let say FILE MAKER ha ha 

would you please guide me ? thanks in advance. 

A Menu-space: with differents icons for differents uses like save etc 

A Workspace: Where the file will be drop(a single log/ini file)  

A function space: Where the functions of the selected element in the dropped file will be display 

An Information space: where the user will be informed about the process.

At the end the name of the file, the name of the selected element of the file and the used(called) function will be written in a text file( kind of a programm-flow).

Oh thank you hooovahh  I didn't see where to directly ask questions. I have try to do it with dynamical download of Vis or using listbox.

I hope you understand my idea
