Overview
This unit contains a group of static classes and some global variables that provide information about the user's computer system and operating system. The static classes are:
- TPJComputerInfo – provides information about the host computer.
- TPJSystemFolders – gets the full path to certain system folders.
- TPJOSInfo – gives information about the operating system information including the platform, product name, product ID code, version and service packs.
In addition, the unit extends the information provided by the
SysUtils unit's Win32xxx variables (such as
Win32Platform) by defining further Win32xxx
variables that store the extended operating system information available on
later NT platform OSs.
Deprecated Code
The TPJSysInfo component and SIGetxxx functions provided
in earlier versions of the unit are no longer compiled by default. The code
can be included by defining the symbol
PJSYSINFO_COMPILE_DEPRECATED before compiling.
Documentation
The component is documented in the System Information Component Wiki.
Users of Delphi version 3 to 7 can also make use of the help file that is included in the download. It integrates with the Delphi 3-7 help system. The help file is a WinHelp file and therefore does not work on Windows Vista unless WinHelp has been downloaded and installed. See Microsoft Knowledge Base Article KB917607 for further information.
Demo Program
A small demo program is also included in the download that shows the information provided by all the unit's classes, functions and global variables.
The demo requires Delphi 4 or later.
