use the same command

[Sergreyn]

Hello,

My VI look like it :

 

I would like to re-use the same command in my "while".

I have several case and I don't want to creat several text command.

If someone kown a trip please tell me how to do.

See you,

That code as written will not work.  You are not making any updates to the string in the loop, therefore you either have a loop that runs once or an endless loop.

But if you want to reuse code, then make a subVI and call that VI multiple times.

[Sergreyn]

The problem using a Sub VI is that I have only one IHM so only one "text command" .

[Dennis_Knutson]

What is IHM supposed to mean? Your code makes no sense.

[Sergreyn]

I just want to reuse the same text command several time. Use a sub vi does not help me because I have another window.

Not really understanding what you're asking for here.  What "text command" are you talking about?  What other "window"?  

Maybe you should post your question in French and let us translate?  Post what you want your code to do and we can probably show you a better way than what you are trying.

Thank for your answer. I think the code I posted shows what I want to do but it's not all the code. My text box ("chaine") is already with others buttons and I don't want to create a sub VI to reuse it.

Hi,

I maybe not correctly undestand your issue, but you can use a local variable for what you are trying to do...

[Sergreyn]

Ok thank you very much It work;

I don't think you want to do that.

You have introduced a race condition with your local variables.

What you want to do is read your "chaine" terminal in your while loop.

Get rid of your two inner while loops.

Wire "chaine" directly into the case structure.

Make a case for "HI" which lights x>y.

make a case for "Hello" which lights x>y2.
