Detailed description

This call gets the value of a property. All properties are stored as strings internally, though this call will allow the value to be returned (and converted) to a variable of any type.


Note it is the expression of the property that is returned. For example, if a property called connection represents port A, reading the value of connection will return the value of port A, where as this call would return the string "$PORTA", which is the stored representation of the property.


In short, referencing the property variable gets the result of the properties expression, while this call gets the expression itself.


Examples

Calling in a calculation

  • Declare a variable 'result' of type STRING
  • Add to a calculation icon:
    result = ::Component.Property.GetValue(handle, "property")
