Threads and socket connections

[alan93]

I have a basic dialog program that connects to another computer over the internet to retrieve some files (small) using a CSocket connection.

It does this repeatedly about every second or 2 for a limited amount of time.

What I am noticing is that the program hangs, or locks up momentarily sometimes during this. Example: moving the mouse over the dialog stops and starts.

Seems like the sending and receiving is stopping the rest of the program.

Is it possible to put sends and receives in a thread ? If so, is there an example of this somewhere?

It is normal when you've put recv() function in your main thread to block everything untill the file is downloading(If you want to know why read in MSDN or Network Programming for Microsoft Windows-very good book).
Check the functions _beginthread() and _endthread() in process.h or afxBeginThread() if you use MFC.

You can also use CreateThread() (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/createthread.asp)
