TCP Socket Listener, Receiving Binary Data into UE4 From a Python Script!

Hi guys! I’m new to unreal, still studying. Thanks for 's tutorial. After implement the code. I have some unsolved errors hope to get some help.

my visual studio 2015 keep telling me I have undefined GetWorldTimerManager() & VShow(). Did I miss including something?

And I also receive the error shows that I can’t add void in front of this –> void tcpiptest::tcpiptest()

I’m using ue4.13.1 thanks for helping me.
