als ik in de help zoek dan kirjg ik dit:
Occurs when a reader object encounters an error reading its data, such as reading the name of an undeclared property or an illegal value.
type TReaderError = procedure(Reader: TReader; const Message: string; var Handled: Boolean) of object;
property OnError: TReaderError;
Description
OnError is used internally by the Delphi environment to report errors. It can also be used to write an event handler to selectively choose to process or ignore errors.
The last parameter passed to the OnError event handler is a var parameter called Handled. By default, the Error method passes False in Handled, but a handler that corrects the error or chooses to ignore the error can set Handled to True, which prevents further processing of the error. If the event handler returns with Handler still set to False, the reader object raises an EReadError exception.
en/of
The type for event handlers that respond when a Windows socket reports an error.
Unit
ScktComp
type
TErrorEvent = (eeGeneral, eeSend, eeReceive, eeConnect, eeDisconnect, eeAccept);
TSocketErrorEvent = procedure (Sender: TObject; Socket: TCustomWinSocket; ErrorEvent: TErrorEvent; var ErrorCode: Integer) of object;
Description
The Sender parameter is the socket component that encountered the error.
The Socket parameter is the TCustomWinSocket object that receives the error notification.
The ErrorCode parameter is the error code returned by the Windows socket API call. Changing this to 0 within an error handler prevents an exception from being raised.
The ErrorEvent parameter indicates what Socket was attempting to do when the error occurred. It is of type TErrorEvent, which can have any of the following values:
ValueMeaning
eeGeneral - The socket received an error message that does not fit into any of the following categories.
eeSend - An error occurred when trying to write to the socket connection.
eeReceive - An error occurred when trying to read from the socket connection.
eeConnect - A connection request that was already accepted could not be completed.
eeDisconnect - An error occurred when trying to close a connection.
eeAccept - A problem occurred when trying to accept a client connection request.
nou..het spijt me zeer maar hier begrijp ik dus echt geen reet van...kan iemand misschien beetje uitleggen?
