Receive data through TCP connection

Hi

I'm receiving a string "Hello" from TCP from a C-program, where I have to display this string in a string indicator in LabVIEW. 

I have the following block diagram I found among the examples: 

The point here is that I can only read the last character "o" in the indicator when I change the "bytes to read" value to 4 bytes, but can read the characters "ello" when setting the bytes to read value to 1. How do I read the whole "Hello" string ?.
