Then add the code in the InitInstance of the program as follows:

LONG WINAPI dbgunhandledexceptionfilter (pexception_pointers pexceptioninfo) {     Cse_exception::_dbgdumperror ( Pexceptioninfo, _t ("E"));     return exception_continue_search;    Program stops running}bool cdcpworkerapp::initinstance () {     //eha     cse_exception::initseexception ();     Catch Unhandled exception     SetUnhandledExceptionFilter (Dbgunhandledexceptionfilter);}
