Public Function MapFilenameToLanguageSID (pszFileName As String, ByRef pguidLangSID As Guid) As Integer

Parameters

pszFileName: String

[in] File name associated with the language service.

pguidLangSID: Guid

[out] Pointer to the language service.

Returns

Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

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.
