Freeware  Vaery Shmelev - unofficial          Free VB ebook Proxy on Visual Basic

			E-book. Free VB eBook - The most elementary single-thread Proxy in Visual Basic. In creating this manual we set ourselves the task to develop a minimum program code playing the role of Proxy-server (transmitting information from one port to another). It is easy to add filtration functions to the program (it will be shown in the supplement), log records, information substitution records (link addresses, advertisement in HTML - for web site promotion).  [ >>>> ]           Create standard Visual Basic project. Deploy element Label “this computer’s IP” on the form                    Connect a new Winsock component to the project for work with the network according to TCP/IP protocol                         - Winsock component      Free Visual Basic ebooks     Deploy two Winsock copies on the form. Winsock1 – for the server part and Oflameron for the client part. The server part (Winsock1) receives queries from the Web-browser (for example, Internet Explorer) through the port, for example, 125 and transmits it to the client part. The client part Oflameron (Winsock2) through standard port 80 transmits queries to the real Web-server.    VB ebook >>>>  Free ebook >>>>  Free Visual Basic ebook >>>>  Free download >>>>
