How to set the default value of the controls to be zero and when I click on a control its value changes to 1.

[Ngouda]

Hello guys,

I have several image controls. I have a simple example of my problem.

On my vi I have 3 controls.

I want the default value of the controls to be zero and when I click on a control its value changes to 1.

How can I do this please? I have no idea how to do this.

Thanks in advance for your help.

Hi ngouda,

use a boolean control set to false by default. When the user clicks the control it changes to true...

When you need a numeric value you can use BooleanTo0/1 function.

Hi GrdW,

Thank you for your answer.

But I didn't quite understand, can you please show me an example?

Thank you

Hi Crossrulz,

Thank you very much for your answer.

Now I have another question please.

On my vi below I want to save the name of the control and its value (0 or 1) in a .txt file in this format: name of control= value of controls.

I got an error trying to do this. Can you please check?

Thanks in advance.

Which error do you got?

You know your 3 controls are booleans: why do you convert the control reference inside to loop to a string reference? Wouldn't it make sense to convert to a boolean reference???

Hi GerdW,

Thanks for your reply. Below is the error I have.

Yes you are right but I don't see how to collect the name of the control and concatenate it with its value. That's why I tried this not so good method.

Do you have a much simpler method and more sense please?

Thanks in advance

Best regards

I did some clean up of your code.  I would highly recommend avoiding using references and searches, etc.  Just use local variables to get your values.
