Which of the following apply to Property Nodes? (More than one answer may apply)

  1. Property Nodes allow attributes of front panel objects to be programmatically manipulated.
  2. Property Nodes can be used to update the values contained in a front panel object.
  3. More than one Property Node can be used for a single front panel object.
  4. Property Nodes contained in a subVI will always cause the front panel to be loaded into memory.

You have a control on the front panel of a VI and you need to modify one of its properties at run time. Which of the following is the best approach you would take?

  1. Create an implicit property node and select the property to modify.
  2. Create a control reference, pass the reference to a property node and select the property to modify.
  3. Create a linked shared variable and select the property to modify the property.
  4. Create a local variable and select the property to modify.

Which plot will change color first?

  1. Plot 1 because properties are executed top-down.
  2. Plot 0 because properties are implemented in numeric order starting at zero.
  3. Both plot will be updated simultaneously due to the multithreading of properties.
  4. It cannot be determined because LabVIEW performs operations in dataflow format.

Which of the following is the best method to update an indicator on the front panel?

  1. Use a Value Property Node.
  2. Wire directly to the indicator terminal.
  3. Use a local variable.
  4. Use a functional global variable.

Does this code snippet demonstrate an appropriate use of a Property Node?

  1. Yes, because updating the value via a Property Node uses less memory than writing to the terminal.
  2. Yes, because updating the value via a Property Node allows for error checking.
  3. No, because you should always wire data directly into indicators when possible.
  4. No, because Property Nodes should only be used with more complex data types.

  2. Property Nodes can be used to update the values contained in a front panel object.
  3. More than one Property Node can be used for a single front panel object.
  4. Property Nodes can be used to programmatically generate a Value Change event.
