Gets the type-instance of the component, >= 1 is valid
- The component to read the instance from
- The default value for this parameter is: this
Returns the type-instance of the component, >= 1 is valid
A components instance is a number referring to how many occurrences of a component exist before this one, including itself. The number is 1 if the component is the first of its type to be added.
This instance number is irrespective of the depth of a component - a component of the same type as the Target is still considered even if it is embedded deep in some other components tree.
Note this call relies on a match of the components GUID, so built-in component types (such as shapes and groups) do not have an instance and it will return zero.
Calling in a calculation
- Declare a variable 'result' of type ULONG
- Add to a calculation icon:
result = ::Component.GetInstance(target)
