        pszFileName:string * 
        pguidLangSID:Guid byref -> int

function MapFilenameToLanguageSID(
    pszFileName : String, 
    pguidLangSID : Guid

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextManager::MapFilenameToLanguageSID(
   [in] const WCHAR *pszFileName,
   [out] GUID *pguidLangSID
);

This method allows you to map a file type to the appropriate language service for that type. This mapping works by looking in "HKEY_LOCAL_MACHINE\ Software\Microsoft\Languages\File Extensions" for entries that map an extension to a SID, that is, a CLSID for a language service that presumably implements IVsLanguageInfo.
