Check Outgoing connection

[Farabi]

I want to check all of my active connection include the port used for all application that used internet connection like netstat.exe did. What function I should use?

You can do this by using the IP Helper API (documentation; http://msdn.microsoft.com/en-us/library/aa366073%28v=VS.85%29.aspx)

Yeah but the .lib file on MASM32 is broken.

Try and run this code; it should work for you.

conoutmon.asm:

.code

start:

INVOKE  GetTcpStatistics, OFFSET tcpStats

INVOKE  MessageBox, 0, ESI, OFFSET szTcpCap, MB_OK or MB_ICONINFORMATION

end start

Thanks for the Code I got it working anyway.
