WinSock 2.0 (1997) source code

Introduction

This is an unofficial source code repo for Lewis Napper's WinSock 2.0 (1997) book. The source code is reproduced here for reference (so you don't need to dig up the physical media of the book) and remains the copyright of the book authors.

Using this repository

To build, you'll need Visual Studio 2019 (any version) with the Desktop development with C++ workload installed. Some samples also use MFC, so you'll also need the C++ MFC for latest v142 build tools (x86 & x64) component installed.

Changes

I'm currently going through the code, restructuring the directories, and adding Visual Studio 2019 projects to build the projects (converted projects are listed below). As this is decades old Win32 code, I don't plan on fixing compiler or security warnings, but if you do copy any code from this repository, it's strongly advised you heed and understand these warnings.

Conversion status

The conversion effort is ongoing and will take some time. Items listed below are successfully converted samples.

Chapter	Sample	Conversion notes
2	Datagram client and server	OK.
	GetHTTP	OK.
	HostInfo	OK.
	WsVer	OK.
	Stream client and server	OK.
4	Chekmail	OK. Requires MFC.
5	Ping	OK.
	PingI	OK.
6	SendMail	OK. Disabled an MFC call to address compiler warning C4996.
	Wsterm	OK. Updated WSTERM.RC2 resource file.
7	EnumProt	The ws2dnet.h header, which defines types for the now defunct DECnet protocol suite, is no longer part of the Windows SDK. The references to ws2dnet.h and its types have been commented out. After the conversion, the build process complained about a missing bitmap file bitmap1.bmp. I'm not sure what this file is about, and I can't find any reference to it in the repository, so I added a dummy bitmap to make the build happy. The ordering of the inclusion of Windows.h and winsock2.h was changed to prevent redefinitions.
	SelProto	OK.
8	Services	The ws2dnet.h header, which defines types for the now defunct DECnet protocol suite, is no longer part of the Windows SDK. The references to ws2dnet.h and its types have been commented out. Windows NT 4.0 (_WIN32_WINNT 0x400) is no longer supported by MFC, and so MFC would not build against this version. I've bumped the version to Windows 10. Disabled an MFC call to address compiler warning C4996.
9	GetHttp2	OK. Changed main() signature.
	GetHttp3	OK. Changed main() signature.
10	httpa	OK. There's actually a bug in this sample where requesting for a file in the hosted directory causes a 404 due to an extraneous "/" being prepended to the file name -- I may eventually fix this.
11	httpmt	OK.
12	🚧	In progress.
