TCP write and TCP read in the same VI.

Hi 

I want to write data to a c-program and also read data from it right after through a TCP connection. How can I implement both options to a single VI. 

I'm sending arrays of pixel values to the -program, then the it will send the arrays back to me. I have made a suggestion, but I don't know whether it is correct or not.

The VI is uploaded and shown in the image below
