Programmatically set the value of the switch back to false

[martin.kretschmar]

Hello,

although we have a link (http://forums.ni.com/ni/board/message?board.id=170&message.id=216160#M216160), we still can't exactly see how to programmatically set the value of the switch back to false. Is there a kind of a property setting node?

Any help would be great! 🙂

If you re using a latch action boolean, it ll automatically get set to False once the button value is read by your code, else it wont...

However, if you use a switch action boolean, you can use a local variable or a Value property node to set its value back to False.

The Value property node colur appears Green, if it is a Switch action boolean.

The Value property node colur appears Purple, if it is a Latch action boolean.

Hello,

we found it ourselves. 😉

With selecting a boolean control in the block diagram, a new method node can be created which resets the control back to its standard value. 🙂

It is nice to see you found it yourself.

But be aware that when you use a Method [Invoke] node, you somehow lose the control of setting the value by yourself in the code.

What you re using is the Reinit to Default method for a boolean.

Today, the default value of your boolean may be False. What if tomorrow another crazy developer sets it to True from the Rt Click menu option -->> Data Operations -->> Make Current Value Default ?

So. you cannot be sure what is the actual default value for that boolean [ for that matter, any control/indicator ].

So, it is better to use locals to set back to the value of our wish [ anywhere we want in the code].

Run the attached Vi & see to it...

Property nodes: Value, Value (Signalling)

Or use a Local.
