System information classes and associated global variables. Information is provided via:

• TPJComputerInfo: a static class that provides information about the user's computer.
• TPJSystemFolders: a static class that gets full path of certain system folders.
• TPJOSInfo: a static class that provides information about the Windows operating system including platform, product and edition, service packs, version numbers, product ID etc.
• Global Win32XXX variables: extra variables to those provided by the SysUtils unit that provide extended OS version information on later NT platform OSs.

Extended operating system detection improved in this release: can now detect Windows Vista, XP Tablet and XP Media Center editions, and WOW64 subsystem of 64 bit Windows.

The TPJSysInfo component and a set of functions that were provided in earlier versions of the unit are also included but are now deprecated.

Some OS detection code based on a translation of example C code on MSDN.

This unit provides various customisable message dialog box components. Three components are installed on the component palette. They are:

• TPJWinMsgDlg
  This component wraps the Windows MessageBoxIndirect API call and displays a message box based on that provided by Windows. This component will be suitable for most purposes and has the lighter footprint.
• TPJVCLMsgDlg
  This component uses the Delphi VCL CreateMessageDialog function to create a form based message box. (CreateMessageDialog is used by the standard Delphi MessageDlgXXX functions). The component provides more flexibility than either the Delphi functions or TPJWinMsgDlg. It should be used when it is necessary to display buttons or combinations of buttons that are not supported by the WindowsAPI message box or when a finer degree of control over the appearance and behaviour of the message box is required. TPJVCLMsgDlg supports all the features of TPJWinMsgDlg and extends them.
• TPJMessageDialog
  This is an updated version of the component supplied in release 1 of this unit. Various bugs have been fixed and the handling of user icons improved. This component is only provided for backwards compatibility with existing projects that use the old version. It exposes the same properties as the old component. Some of these properties vary from those common to TPJWinMsgDlg and TPJVCLMsgDlg. It is recommended that TPJWinMsgDlg or TPJVCLMsgDlg are used in new projects.

A demo project is included along with an OpenHelp compatible help file that integrates with Delphi 3-7.

• TAudioMixer
  Provides an easy interface to manage audio mixer controls.
• TWaveStorage
  Stores a single wave audio and provides access to its informational fields.
• TWaveCollection
  Stores a collection of wave audio's as resource and provides access to their informational fields.< /LI>
• TAudioPlayer
  Plays a wave audio, which is stored in the component.
• TAudioRecorder
  Records wave audio and stores it in the component.
• TStockAudioPlayer
  Plays wave audio from a TWaveStorage or TWaveCollection component, a stream, or a file.
• TStockAudioRecorder
  Records wave audio to a TWaveStorage or TWaveCollection component, a stream, or a file.
• TLiveAudioPlayer
  Plays wave audio from user defined buffers.
• TLiveAudioRecorder
  Records wave audio to user defined buffers.
• TAudioRedirector
  Records wave audio from an input audio device and plays it on an output audio device.
• TMultimediaTimer
  Is a high resolution timer.

This unit provides various components, classes and routines for handling Windows shell folders.

It contains:

• a component that provides information about a specified special shell folder,
• a class that enumerates all the special shell folders,
• routines to manipulate special shell folder information,
• a component that encapsulates the Windows Browse for Folder dialog box and permits a large degree of customization,
• a property editor for special shell folder identifiers.

A OpenHelp compatible help file is included for integration with Delphi 4 to 7 IDEs. Help file can be used idenpendently with Delphi 2005/6.

A fully documented demo program is included.

Update info:
Release 2.2.2enables compilation with Delphi 2005/6 and fixes range check bug in demo project.
Release 2.2.1 fixes a property editor bug.
Release 2.2 adds support for 'new style' browse dialog, improves help and provides further special folder ids.
Release 2.1 adds support for further shell folders and removes Delphi 6/7 compiler warnings.
Release 2 fixes some bugs on NT OSs, provides extended display options, adds further event handlers for Browse for Folders dialog box, adds support for Delphi 6 & 7 and adds a demo application.

Two components are provided that enable applications to support Windows Explorer file drag and drop. The components are:

• TPJDropFiles - This windowed component catches files dropped anywhere over its window. It can act as a container for other components.
• TPFormDropFiles - This non-visual component catches files dropped anywhere on its form, including the non-client areas.

Key features of these components are:

• An OnDropFiles event is triggered when files are dropped.
• The names of dropped files are made available through the Files array property. For convenience, the name of the first file is also stored in the FileName property.
• The list of dropped files can be configured to include only files, only folders or all files and folders.
• Dropped folders can be recursed so that all the files and sub-folders in each of the dropped folders are listed.
• Filters can be applied to the dropped files and folders. This is done in one of two ways: (1) by handling the OnFileFilter event and deciding which files and folders to pass through the filter and (2) by linking the drop file component to a special file filter component, derived from the abstract TPJFileFilter. In this case the dropped files are automatically filtered by the filter component. Two filter components are provided: TPJExtFileFilter that filters according to file extensions and TPJWildCardFileFilter that filters using DOS-style wildcards. Developers can create further filter components by deriving from TPJFileFilter.
• The mouse co-ordinates where the files were dropped can be retrieved, as can a reference to any control under the mouse cursor at the time.
• The OnBeforeDrop event can be used to do pre-processing before the files are actually dropped.
• The IsFolder array property tells if an equivalent item in the Files list is a file or a folder.
• The owning window can be brought to the front when files are dropped.
• Some design time assistance is provided by component and property editors.

A Delphi 3-7 OpenHelp compatible help file is supplied. Additionally an a-link keyword file is provided for use with Delphi 6/7.

• Automatically adjusts printer's paper size and orientation at theprint time
• Automatically adjusts mapping modes
• Preview pages can be scaled with an arbitrarily zoom factor
• Shows created pages while the new pages are in process to create
• Displayed pages can be scrolled by mouse dragging
• Pages can be saved/restored to/from disk
• Each page is accessible as a Windows MetaFile image
• Regardless of number of previewed pages and their complexity, only consumes a small portion of Windows resources
• Has some methods to easily render rich text format and images
• Can manage custom paper sizes and forms
• Has a complete set of events

This property editor has been designed to get round two limitations of the standard Delphi string property editor:

1. inability to handle multi-line strings (i.e. strings with embedded CR/LF characters).
2. 255 character limit to string length.

The enhanced property editor works with all string and TCaption properties. It adds an ellipsis button to the right hand side of the data entry area in the property editor. Clicking the button displays a dialog box in which the property's value can be entered. Pressing return starts a new line. There is no practical limit to the length of strings that can be entered. The ability to type directly into the object inspector has been retained.

The edit dialog is resizable. Word wrapping can be switched on or off - and both settings are persistent. Text can be loaded and saved to disk.
