Please contact the application's support team for more information. ____________________________________________ The same above code is working in other all windows o/s except on windows 2003. Some one also got the same problme while using _bstr_ function and he got the problme because the system sends the serial number is ulong.Thats what the system is crashed... Please send me any idea or workaround to my id. rammohan@india.com Tahnks in advance... Thanks in advance... Rammohan Alampally, rammohan@india.com
