rssStream variable that contains the characteristics of the specified RSS stream. If the initialization of the stream fails, the stream is empty and ErrorInfo returns more details about the error.

Source of the RSS stream used for the initialization. This parameter can correspond to:

• An Ansi character string or a buffer containing the content of the RSS stream. In this case, <Type of Source> must correspond to the fromString constant.
• A character string containing the full path of an XML file. This file must be accessible from the current computer. In this case, <Type of Source> must correspond to the fromFile constant.
• A character string containing the URL address. The content of the RSS stream is retrieved from this URL. In this case, <Type of Source> must correspond to the fromURL constant.

Indicates the source of the RSS stream to load.

fromString	The RSS stream to load is contained in an Ansi character string or in a buffer.
fromFile	The RSS stream to load is contained in a file.
fromURL	The RSS stream to load is accessible by a URL.

An automatic detection is performed if this parameter is not specified. The type of the source is automatically deduced from <Source of RSS Stream>:

• if <Source of RSS Stream> starts with "http://", the fromURL constant will be automatically used.
• if <Source of RSS Stream> starts with a drive letter or with a UNC path, the fromFile constant will be automatically used.
• otherwise, the fromString constant will be automatically used.
