    COMPersistHelper::SaveToFile — Save object to file

    Description

    public COMPersistHelper::SaveToFile(?string $filename, bool $remember = true): bool

    Saves a copy of the object to the specified file.

    Parameters

    filename
    The name of the file to which to save the object.
    remember
    Indicates whether the filename parameter is to be used as the current working file. If true, filename becomes the current file and the object is supposed to clear its dirty flag after the save.

    Return Values

    Returns true on success or false on failure.

    Errors/Exceptions

    A com_exception is thrown if the associated object does not implement the COM interface IPersistFile, or when calling the IPersistFile::Save() method failed.
