Due to busy work, I haven't been here for a long time. Background: One of the MDI child forms is a navigation form, which defines CLOSING event processing: checks whether the close mark of the form is allowed. If not, cancels the close operation, this ensures that the navigation form is permanently present without being closed. Problem: When the MDI container form is closed, the close event of one of the Ch
