//  browser.h 
// 
//  Sample Windows app for SMS API. 
// 
//  This program illustrates the use of most of the SMS API set in order to 
//  implement a generic Objectity browser. 
//  Since this program is statically linked with smsapi.lib/dll it acts as 
//  an SMS objectity browser only. 
// 
//  Using this program it is possible to view all containers and folders 
//  that are implemented in the SMS API.
