-// Name: db.h

// Purpose: Header file wxDb class. The wxDb class represents a connection
// to an ODBC data source. The wxDb class allows operations on the data
// source such as opening and closing the data source.
// Notice: This class library and its intellectual design are free of charge for use,
// modification, enhancement, debugging under the following conditions:
// 1) These classes may only be used as part of the implementation of a
-// wxWindows-based application
-// 2) All enhancements and bug fixes are to be submitted back to the wxWindows
-// user groups free of all charges for use with the wxWindows library.
+// wxWidgets-based application
+// 2) All enhancements and bug fixes are to be submitted back to the wxWidgets
+// user groups free of all charges for use with the wxWidgets library.
// 3) These classes may not be distributed as part of any other class library,
// DLL, text (written or electronic), other than a complete distribution of
-// the wxWindows GUI development toolkit.
+// the wxWidgets GUI development toolkit.
