Hello,michele I got somet questions as: 1. Some qos values in cpp client(msgqosdata.cpp) will lost when toxml() method was invoked to convert qos object to xml string, such as forceDestory. 2. In StringTrim::isTrue() method, in parameter always is "1" or "0",so "true" and "TURE" are not enough. Thanks for your help. pikaiyuan 2005-03-17
