synchronous support for calls between suites with different features. To ensure that objects with different multithreaded features can be invoked correctly with each other without introducing synchronization problems, simplifying programming (which may actually be more complex). For example, if an object is written to forget to consider multithreading, or have no time to consider, or do not need to provide support for multithreaded, this time you can designate the object as STA, let COM automat
