OSAAvailableDialects

You can use the OSAAvailableDialects function to obtain a descriptor list containing information about each of the currently available dialects for a scripting component.

FUNCTION OSAAvailableDialects
               (scriptingComponent: ComponentInstance;
                VAR resultingDialectInfoList: AEDesc): OSAError;

scriptingComponent

A component instance created by a prior call to the Component Manager function OpenDefaultComponent or OpenComponent (see page 10-4).

resultingDialectInfoList

The returned descriptor list.

DESCRIPTION

Each item in the list returned by OSAAvailableDialects is an AE record of descriptor type typeOSADialectInfo.

CONST typeOSADialectInfo = 'difo';

Each descriptor record in the descriptor list contains, at a minimum, four keyword-specified descriptor records with the following keywords:

CONST
   keyOSADialectName       = 'dnam';{used with descriptor record }
                                    { of any text type, such as }
                                    { type typeChar}
   keyOSADialectCode       = 'dcod';{used with descriptor record }
                                    { of type typeShortInteger}
   keyOSADialectLangCode   = 'dlcd';{used with descriptor record }
                                    { of type typeShortInteger}
   keyOSADialectScriptCode = 'dscd';{used with descriptor record }
                                    { of type typeShortInteger}

Rather than calling OSAAvailableDialects to obtain complete dialect information for a scripting component, it is usually more convenient to call OSAAvailableDialectCodeList to get a list of codes for a scripting component's dialects, then call OSAGetDialectInfo to get information about the specific dialect you're interested in.

RESULT CODES

noErr	0	No error
