The ScriptingLanguageInfos collection contains ScriptingLanguageInfo objects that provide information about each Microsoft® ActiveX® scripting language that is available on the system. You can use these scripting languages in ActiveX Script tasks, ActiveX Script transformations, and step scripts.
Obtain a reference to the ScriptingLanguageInfos collection from the Application object.
You can iterate through the objects of the ScriptingLanguageInfos collection using the Item method and Count property. However, it is faster to use For Each ... Next in Microsoft Visual Basic®.
DTS maintains a cache, in the operating system registry, which holds the scripting language information. If the UseCache property is TRUE the cache is scanned, rather than all registered classes, when iterating through the ScriptingLanguageInfos collection. Use the Refresh method to update the cache from the registered classes section of the system registry.
