API Component.GetInstance

	GetInstance
Gets the type-instance of the component, >= 1 is valid
- HANDLE	Target
The component to read the instance from
- ULONG	Return

Detailed description

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.

Examples

Calling in a calculation

• Declare a variable 'result' of type ULONG
• Add to a calculation icon:

  result = ::Component.GetInstance(target)
