CleanupKeyContext Event

Fires when the application-defined data stored in a registry key context needs be cleaned up.

Syntax

typedef struct {
  void* KeyContext;
  int ResultCode;
} TcbfCBRegistryCleanupKeyContextEventParams;

typedef void __fastcall (__closure *TcbfCBRegistryCleanupKeyContextEvent)(System::TObject* Sender, TcbfCBRegistryCleanupKeyContextEventParams *e);

__property TcbfCBRegistryCleanupKeyContextEvent OnCleanupKeyContext = { read=FOnCleanupKeyContext, write=FOnCleanupKeyContext };

Remarks

This event fires when the specified KeyContext is about to be discarded, giving applications a chance to clean up any information stored in it. Please refer to the Contexts topic for more information.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.

This event is fired synchronously; please refer to the Event Types topic for more information.
