Parameters
- pszFileName
Type: System.String
[in] File name associated with the language service.
- pguidLangSID
Type: System.Guid%
[out] Pointer to the language service.
Return Value
Type: System.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.
