TH1 sends some data back to client C1, C1 reveives the data and send more data to the server on the same connection which was establisehd on port 21. This data arrives at server and is received by thread Th1 while the main the main thread of Server continues to listen on port 21. My question is how does the further data sent by client C1 on the same connection which was made on port 21 automatically goes to the thread Th1 ? even though the main thread of server is listening on...

Manually adding these files to a VS Projects to build, results in the following error "Python.h": No such file or directory Adding the following files to the project from C:Pythoninclude lastly results in ...
