4D and WebSTAR are very extensive and complete programs. 4D, a development
tool, and WebSTAR, a Web server, should serve the need for most developers
as is, but there are instances when developers may wish to enhance, or add
tools or utilities that are not built into 4D or WebSTAR. This is why 4D
provides an API for both 4D and WebSTAR. If developers find that they are
not able to do a certain function within either 4D or WebSTAR, it is quite
likely that with the APIs, developers can create their own Plug-ins that
meets their needs.
Before starting to write a plug-in, there are a few things you need to have:
1) You will need a C/C++ compiler. The two compilers that our Plug-In Wizard supports are Codewarrior v5.3 or later, and Visual C++ v6.0 or later.
2) You should have a cursory understanding of C/C++. We suggest that you have at least been exposed to C/C++ in the past before attempting to write a 4D plug-in. While the command syntax may seem similar to 4D, there are differences that may cause problems at a later point. If you do not have experience with C/C++ we would recommend picking up a book or perhaps looking through an online tutorial on C/C++.
