| - | Scripts run in an interactive mode by default (''[[scriptcommand_option|option batch off]]''). There's no equivalent for this in .NET assembly, which always runs in a batch mode, equivalent to ''option batch on'' in scripting mode. | + | Batch scripts (specified using ''/script'' or ''/command'' [[commandline#scripting|command-line switches]]) run in an ''[[scriptcommand_option#batch|option batch abort]]'' mode. |
| - | To emulate ''option batch abort'' (a recommended setting, as used in most scripting examples), call a method ''[[library_operationresultbase|OperationResultBase]].Check'' for all ''Session'' methods that return an operation result (such as ''[[library_session_getfiles|GetFiles]]'', ''[[library_session_putfiles|PutFiles]]'', and ''[[library_session_synchronizedirectories|SynchronizeDirectories]]''). | + | To emulate the ''option batch abort'' call a method ''[[library_operationresultbase|OperationResultBase]].Check'' for all ''Session'' methods that return an operation result (such as ''[[library_session_getfiles|GetFiles]]'', ''[[library_session_putfiles|PutFiles]]'', and ''[[library_session_synchronizedirectories|SynchronizeDirectories]]''). |

| + | If you are using ''option batch continue'' mode, handle ''[[library_session_queryreceived|Session.QueryReceived]]'' event and call ''[[ library_queryreceivedeventargs#continue|QueryReceivedEventArgs.Continue]]'' in the handler. //For an example, see [[library_example_recursive_download_custom_error_handling|*]].// | ||
