how to read the uploaded ecu call value in my c# application

[sanjeevnaik]

hello
my question is how to read the uploaded ecu call value in my c# application.
In my c# application to read the calibration value i am sending upload command on CRO using PCAN-Basic CAN write metode and and continuously polling DTO using PCAN-Basic CAN Read methode to read the uploaded calibration value. But am not able to read the uploaded value in c# application but its visible in pcan viewer software. and most of the time i am getting the PCAN_ERROR_QRCVEMPTY error some time i am getting uploaded value but most of the time PCAN_ERROR_QRCVEMPTY with no value .Could u please help me to fix this problem i am using pcan-ccp api and pcan-basic api in my C# application

if you use the CAN Layer 2 API - PCANBasic.DLL - you receive all CAN Frames on the BUS like the PCAN-View.
If you use a HighLyer API like CCP/XCP or UDS you read only the protocol specific CAN Frames.
With your description, we cold not solve your problem, because you talk about Layer2 API and HighLayer Protocol API.

actually i want to read the ecu variable value(2 byte) in my application using ccp protocol.if i used upload ccp methode of HighLyer API like CCP i am able to see the variable value in DTO using can viewer software but not able to read the value in my application . that's why i used CAN Layer 2 API - PCANBasic.DLL to send upload command using write method but not able to read DTO response in my application.please tell me how to read the ecu variable value using HighLyer API like CCP .
