excel sheet sending /receiving in serialport C#

C#4.0

hi,

am developing project on handheld system. now am using two c# applications just for testing whether they are sending /receiving data through serial port.

1st application is on COM5-->port ,first ,1st application will send excel data row by row ,when one row is received by 2nd application that should send $ machID # back to first application.
Here machid is in exceldata whatever it is received.

second thing is : i need to load excel data from 2nd apllication to 1st application.in that case
1st application should read in correct formet and save in excel sheet.

here my question is:upto first thing am somewhat ok, coming to second thing where i need to write the code in 1st application.is it in serialPortDatareceived event or in some where


1st application code is
