CustomContextMenu is intended to make it easy to add your own menu items to the shell context menu (the menu you get when you right-click a file or folder).

It is an abstract class which contains four methods you must override, in order to add your menu items and execute them.

Includes ready-to-install demos, documentation, and install-scripts. Can handle selection of multiple items.

New in 2.0.0: Can handle owner-drawn menu items.

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.

This release adds support for Delphi 2005/6.

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.

The Windows XP Embedded Enhanced Write Filter (EWF) is used to protect one or more disk volumes by intercepting write requests to the volume and redirecting it to an overlay volume, either RAM or another disk. Note the EWF header conversion is only useful on Windows XP Embedded with the Enhanced Write Filter DLL installed. It is not available on Windows XP Pro, or other operating systems. EWF is designed to protect the Windows boot volume so effectively it's write protected and boots up identically each time, with any changes made to a protected drive being lost on power down. If changes need to be saved, EWF API calls are needed followed by a reboot to actually update the protected drive.

Magenta Systems WMI and SMART Component contains WMI, SMART and SCSI PassThrough functions, of particular use for getting hard disk information and configuring network adaptors, but also for many other general uses. MagWMI which allows access and update of windows system information using Windows Management Instrumentation. MagWMI provides general view access to any WMI information using SQL like commands, and also a number of dedicated function relating to TCP/IP configuration, such as setting the adaptor IP addresses, and the computer name and domain/workgroup. There are also some examples for getting BIOS and disk drive information using WMI, and also a method using SMART for getting disk information since WMI has limitations on Windows 2000. SMART also returns disk failing or fault information. For disks that don't support SMART, SCSI Pass Through is used to get the drive serial number.

PBPathList is a component that makes it easier to use to the Windows built-in shellfolders. Depending on your Windows version it makes a list with 20-40 paths. The individual paths can be called like: PBPathList1['%PERSONAL%']. The component can simulate paths not present on the system. Included is the free 'SHFolder.dll' which let you access shell-folders on older systems - even those not defined. You can build system-independent paths like '%PERSONAL%\MyFolder' and get the actual path at runtime. You decide the case of the returned paths: pcDontCare, pcLower, pcUpper, pcUpperName (First letter upper - the rest lower). Also included are some functions to work with paths: 'DisplayPath', 'FullPath', 'CreateShellfolder' and 'UpperName'. Version can also get the displaynames of virtual folders. Version has been optimized by dynamically loading 'SHFollder.dll' and only making one list even if you have several PBPathList components in your application. Context-sensitive help is included. Compiled demo can be download from my homepage. [more]

Multiprocessor PCs with large cache memories are no more rare. On this kind of machines high performance multithreading applications can be adversely affected by the default behaviour of the scheduler that often causes excessive thread process hopping. This can be prevented using process and thread affinity masks. This component simplifies their use.

PwrSave is a small component to prevent interruption of program execution due to Windows shutdown, hibernate, standby or user log off. When writing programs for data aqcuisition, control systems or servers these might be very undesired. This component will prevent these events and/or gives you the opportunity to take necessary action when such events occur.
