170 Day 6
NOTE
Files with extensions that begin with a tilde (~) are backup files.
C++Builder may create several backup files, depending on the number
of source files in the project and the project options you have set.
Project options are discussed on Day 10, “More on Projects.”
When you first create a project, C++Builder creates a minimum of six files (assuming a typical
C++Builder GUI application):
■ The project source file
■ The main form source file
■ The main form header file
■ The main form resource file
■ The application resource file
■ The project makefile
The project source file is the file that contains the WinMain() function and other C++Builder
startup code. You can view the project source file by choosing View | Project Source from the
main menu. The main form source file and main form header file are files that contain the class
declaration and definition for the main form’s class. C++Builder will create an additional
source file and header for each new form you create. The main form resource file and
application resource file are binary files that describe the main form and the application’s icon.
I’ll explain that in more detail a little later, in the section titled “Dialog Boxes in Traditional
Windows Programs.”
Somewhere in this process, C++Builder creates the project makefile. The makefile is a text file
that contains information about the compiler options you have set, the names of the source
files and forms that make up the project, and what library files have to be included.
NOTE
There are two types of library files. A static library contains common
code that an application needs in order to run. An import library is
needed when your application references functions in a DLL, such as
the Windows API functions. The number and exact filenames of the
library files required depend on the features your application uses.
Fortunately, you don’t have to worry about managing the library files
because C++Builder takes care of that detail for you. Library files have
an .LIB extension and are tucked away in your C++Builder \lib
directory.
