Freedock by Sean Gordon is a Windows "dock" program that includes the full source code in C. A dock is kind of a miniature version of Program Manager that holds icons for the small number of applications that you really use every day. Freedock also provides the nicety of remembering your preferred window geometry for each application that you register with it as well. This saves you from having to continually re-arrange your windows each time you startup an application. A "previewer" allows you to check or change the window geometry without actually launching the applications. The entire dock can be scaled in a way similar to the MS Office Manager dock. Fig. 1 shows Freedock being configured for launching Microsoft Money.
Freedock includes compiled versions of a Win16 executable for Windows 3.1 (FREEDK16.EXE) and a Win32 executable for Windows 95 and NT (FREEDK32.EXE). The Freedock archive includes source code written in C for use with Borland C/C++ or Microsoft Visual C/C++ v1.5 (16-bit) and v2.0 (32-bit). In the Win32 version, you can choose to start applications in separate memory.
Gordon advises: "If it does not do everything you want it to do, you can modify the source code and add functionality to it." Freedock is freeware and any programs derived from its source must remain freeware.
SWMP includes several example .MOD tracks for you to experiment with as well as a standalone MS-DOS player program (SWMP.EXE). For developers, SWMP provides an API and calling interfaces for Borland C/C++, Assembler, and Pascal. You can integrate the library simply by including the header file and linking in MOD_DRV.OBJ (source not provided).
The driver has a small API but you can start your first MOD file playing with as few as three function calls. A powerful hardware detection routine can autodetect the operating parameters of a SoundBlaster, SoundBlaster Pro, or Gravis UltraSound digital audio adapter. This lets users avoid having to remember obscure DMA and I/O port settings.
SWMP is freeware and can be incorporated into other freeware programs. If you want to use SWMP in a commercial product, you must contact the author first.

Additionally ACE contains a higher-level network programming framework that integrates and enhances the lower-level C++ wrappers. This framework supports the dynamic configuration of concurrent network daemons composed of application services. This is similar to the "inetd" mechanism in Unix.
ACE is currently being used in a number of commercial products such as an ATM signaling softwaret, PBX monitoring, network management for mobile communications systems, and an enterprise-wide distributed medical imaging system for medical engineering.
The "Diffpack home page" (http://www.nobjects.com/Diffpack/) organizes all related documentation and source code for the SINTEF Diffpack project at the University of Oslo (Norway). The goal of Diffpack is to develop a fully object-oriented framework in C++ for solution of partial differential equations (PDEs). PDEs often arise in the mathematical modeling of physical processes involving for example fluid mechanics or waves. The best demonstration of the power of Diffpack is to look at some of the successful application areas in which its used:
Of course, the raw data from Diffpack is much more useful if you have something to visualize it with. Diffpack can interface with gnuPlot and plotmtv. You can even construct MPEG movies from multiple visualization frames. Fig. 2 shows a Diffpack visualization of a finite element based simulator for two-phase (oil/water) porous media flow.
Diffpack has been certified to run on any of the following environments: Hewlett Packard HP-UX 9.05 and C++ 3.50, Silicon Graphics IRIX 5.2 and C++ 3.2.1, Sun Sparc Solaris 2.3/SunOS 5.3 and C++ 4.0
The Fresco Home Page (http://www.faslab.com/fresco/HomePage.html) is maintained by Denis Bohm and provides detailed documentation and source code on the Fresco user-interface system. Fresco is an object-oriented application programming interface (API) for graphical user interfaces, covering functionality in Xlib and Xt, and adding structured graphics and application embedding. The Fresco specification and sample implementation are under development by the X Consortium as an open, multi-vendor standard. Fresco offers a broad range of functionality, including low-level display and window management, structured graphics hierarchies, and UI widgets such as buttons and editors. An application may choose to use part of Fresco within another environment, such as using Fresco structured graphics capabilities from within Xt, or an application may choose to use Fresco solely. Fresco uses the CORBA standard object model, which allows for object distribution and provides a high-level Interface Definition Language (IDL). Fresco has been certified to run on the following platforms:

I'm new and I would like to try and get some information about this language" C/C++ Answer Man: Your first stop should be DJ Delore's home page where you can find out where to get the GNU C++ compiler (known by insiders as "g++"). Here's a link for you to try -- http://www.delorie.com/gnu/ email@example.com writes: "I would like the Internet Header Files for Programming in c/c++." C/C++ Answer Man: Well, its hard to tell you much without knowing the exact protocol that you want, but I can tell you that you can find all the Internet RFCs (Requests For Comment) at -- http://www.cis.ohio-state.edu/hypertext/information/rfc.html Each RFC contains all of the constants and structures that you'll need and thus serves the same purpose as a header (.h) file. firstname.lastname@example.org writes: "I am very much interested in C++ programming. I have started to use the STL with G++ 2.7.0 and I am in troubles. I thought this was a good point to find some help. I would like to get news periodically about what's going on in the C++ world. Thank you." C/C++ Answer Man: Although I'm far from an expert on use of the Standard Template Library, there are plenty of folks out there who can give you a hand.

C/C++ Answer Man: There's two great freeware programs you should try out: * Mordor is a MUD server, which allows multiple individuals to log in and play. This is often called the driver or engine. * Muddle is a MUD client, and can be used by players to log into MUDs. It allows you to automate many functions of your character through a relatively simple scripting language. Both of these are written in C and can be found at http://moria.bio.uci.edu/req.html firstname.lastname@example.org writes: "Right now I'm hunting for a grammar for C++" C/C++ Answer Man: And well you might hunt for such a thing, even though it should be included with your compiler. You'll find a pointer to a C++ grammar in the comp.lang.c++ FAQ. Here's a pointer to the relevant portion http://osiris.sund.ac.uk/online/C++/part19#Q126 The grammar can be accessed by anonymous ftp from the following sites: * ftp://ics.uci.edu/ftp/gnu/c++grammar2.0.tar.Z and byacc1.8.tar.Z * ftp://mach1.npac.syr.edu/ftp/pub/C++/c++grammar2.0.tar.Z and byacc1.8.tar.z Jim Roskind can be reached at email@example.com
