I. In-process components and out-of-process Components As mentioned above, COM components support both in-process components and out-of-process components. The advantage of in-process components is fast and convenient. However, if any component crashes, the main process will crash. Components outside the process are slow but stable. If a component crashes somewhere, at most there is no result and the main process will not crash (for example, if the
