Comments
The ppwszInitializationString retrieved using this method will have any leading or trailing spaces trimmed from it. Hence, the string may not be exactly the same one as written using the WriteStringFromStorage method. For example, passing in the string " Provider=MSDASQL.1; User ID = sa " will be returned as "Provider=MSDASQL.1; User ID = sa"
