How can I convert Object to string and print the error warning message directly via VB?

Thx for you reply, now the log message is "You are trying to call the "FullName" method or property of the "CMDClass" object that does not exist.Not found Object Non-existent object   17:18:37    "





As you can see, Aliases.Sys.processCMD.CMDClass is a name after name-mapping，What I need is to give warning message which contain "Object's name-mapping name" when object not exist.



In a word, how can I convert Object type to string type in Testcomplete7.5 via VB script.
