Very cool tool, and useful for a lot more than just reading log files. For example, I've just finished a low usage intranet ASP page using the logparser COM object to query .csv files, based on input from a web form, reading the results into a recordset then writing the filtered results to an output web page in table form. The speed that it does those file searches against multiple large files is amazing. The more I look at it the more uses I see for it.
