CloseKeyHandle Event

Fires when an application-provided registry key handle should be closed.

Syntax

class CBRegistryCloseKeyHandleEventParams {
public:
  void *KeyContext();
  qint64 KeyHandle();
  void *KeyHandleContext();
  int Error();
  bool Processed();
  void SetProcessed(bool bProcessed);
  int ResultCode();
  void SetResultCode(int iResultCode);
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void CloseKeyHandle(CBRegistryCloseKeyHandleEventParams *e);
// Or, subclass CBRegistry and override this emitter function. virtual int FireCloseKeyHandle(CBRegistryCloseKeyHandleEventParams *e) {...}

Remarks

This event fires when the application-provided registry key handle, specified by KeyHandle, should be closed; and the associated KeyHandleContext cleaned up.

The KeyContext parameter is a placeholder for application-defined data associated with the registry key. Please refer to the Contexts topic for more information.

The Error parameter reflects the error code of any error that occurred while using the application-provided key handle.

The Processed parameter indicates whether the application has processed the event and closed the key handle; it is false by default. If the application does not set this parameter to true, then the class will close KeyHandle with the Windows API's RegCloseKey function when the event handler returns (unless an error code is returned via ResultCode).

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.
