The following typographical conventions are used throughout this book:
| Convention | Meaning |
| Bold text | Indicates a word that is a function name, data type, or other fixed part of the Microsoft Windows and OLE Application Programming Interface. For example, OleDraw is an OLE-specific function and OLEOBJECTVTBL is an OLE-specific data structure. These words must always be typed exactly as they are printed. |
| Italic text | Indicates a word that is a placeholder or variable. For example, ClassName would be a placeholder for any OLE object class name. Function parameters in API reference material will be in italic to indicate that any variable name can be used. |
| CAPITALS | Indicates MS-DOS filenames and paths as well as constants. For example, C:\WINDOWS\SYSTEM\OLECLI.DLL is an MS-DOS path and filename. WM_DESTROY is a contant. |
| monospace | Indicates source code and syntax spacing. For example: |
|
typedef struct _APPSTREAM { OLESTREAM olestream; int fh; } APPSTREAM; |
Note The code examples in this book follow the variable-naming convention known as Hungarian notation, invented by programmer Charles Simonyi. Variables are prefixed with lower-case letters indicating their data type. For example, lpszNewDocname would be a long pointer to a zero-terminated string named NewDocname. See Programming Windows by Charles Petzold for more information about Hungarian notation.
