ScripterExport void ProcessMAXScriptException	(	MAXScriptException &	e,
		const MCHAR *	caption,
		bool	displayErrorMessageBox,
		bool	showSourcePosition,
		bool	isTerminalHandling,
		bool	quietErrors = false
	)

This method centralizes the handling of maxscript exceptions in c++ code.

It's typical usage looks like:

ScopedMaxScriptEvaluationContext scopedMaxScriptEvaluationContext; MAXScript_TLS* _tls = scopedMaxScriptEvaluationContext.Get_TLS(); two_value_locals_tls( thingValue, propNameValue ); try { ScopedSaveCurrentFrames scopedSaveCurrentFrames(_tls); vl.thingValue = InterfaceFunction::FPValue_to_val( thing ); vl.propNameValue = Name::intern( propName ); vl.thingValue = vl.thingValue->get_property( &vl.propNameValue, 1 ); vl.thingValue->to_fpvalue( retVal ); } catch (MAXScriptException& e) { ProcessMAXScriptException(e, _T("GetScriptedProperty"), false, false, true); } catch (...) { ProcessMAXScriptException(UnknownSystemException(), _T("GetScriptedProperty"), false, false, true); }

Parameters

e	The maxscript exception to process
caption	The string to be used in the title bar of the error message box, and is used as part of the verbose description of the exception. Can be null.
displayErrorMessageBox	If true, an error message box is displayed (unless max is in quiet mode).
showSourcePosition	If true, source position of error is shown in maxscript editor.
isTerminalHandling	If true, terminal handling of the exception is occurring. If false, the catch will be rethrowing the exception.
quietErrors	If true, error information is not written to Listener, a brief description of the exception and its source location is written to the log file.
