插入符的问题 MFC 没有DestroyCaret

Question

The system caret is a shared resource. CWnd should create a caret only when it has the input focus or is active. It should destroy the caret before it loses the input focus or becomes inactive.

MFC 的 说明里说失去焦点后应该Destroy Caret，可MFC本身（CWnd类的成员函数里）没有相关函数，为什么？调用API吗？不至于吧？

Answer 1

BOOL DestroyCaret(VOID);
