wxWidgets/demos/dbbrowse/dbtree.cpp
George Tasker 645889ad25 Huge cleanup of the code. Reformatting, spelling fixes, standardizing on wxWindows conventions, etc. 
Changed the couple lines of code required to work with checkins of the new ODBC classes that use wxStrings.
Fixed a ton of memory leaks
Demo still crashes on exit though - this problem has exited for nearly a year though.
