#region History
// 2010-26-03 OD Some light corrections
/* 06.01.2012 JB adding Identity/NDC reading, displaying, filtering support.
* replaced IsNullOrWhiteSpace -> IsNullOrEmpty in doMenuFilter since logFilter.Trim() is called, thus there will never be WhiteSpace.
* added multi-logentry-select to concatenate multiple messages into the message textbox. */
