This unit contains a set of three speed button derived components that either display pop-up menus associated with the buttons or form connected button / menu button pairs. The components are:

• TPJMenuSpeedButton -- which can display an associated pop-up menu when clicked.
• TPJLinkedMenuSpeedButton -- links to a master button and displays an associated pop-up menu when clicked.
• TPJLinkedSpeedButton -- a speed button that can link to and control a slave button that accesses a pop-up menu.

Comes with fully integrated help and a demo project.

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.

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.

TPJVersionInfo is a 32 bit non-visual component for all Win32 versions of Delphi and C++Builder that encapsulates the version information contained in an executable file's resources.

The component reads information from a designated file's VERSIONINFO resource. The required file is specified in the component's FileName property. Setting FileName to the empty string fetches version information for the executable containing the component. The boolean HaveInfo property indicates whether the file contains version information. This component can access variable file information for each language provided in the resource.

Run-time properties enable access to to version information. Properties enable:

• Access to fixed file information, either by field or the whole record.
• Access to the number of translations stored in the version information.
• Selection of the translation for which information is to be returned by other properties.
• Access to the language and code page of the current translation - by code and by name.
• Access to the string file information for the current translation - named properties access the Microsoft-defined string information, while an array property gives access to any string item by name.

The component makes calls to the Windows API. Therefore the version information being read must follow the Microsoft guidelines - be warned that not all software complies!

For detailed information about version information refer to the Win32 SDK.

A help file is provided that integrates with the help system of Delphi 3 to 7. An a-link keyword file is provided for integration with Delphi 6 and 7.

Source code of two demo programs is also provided.

TPJHotLabel descends from TLabel. It provides a clickable label that can start the default browser or email client to access a specific URL. Key features of the component are:

• The URL property is used for storing the URL to be accessed when the label is clicked.
• The Caption property can either store descriptive text or can automatically reflect the URL.
• The label can be highlighted using a user-defined font when the mouse passes over it.
• The label displays the "hand point" cursor by default. For versions of Delphi that do not support provide the crHandPoint cursor, a custom cursor is linked in to the program by the component.
• The component's pop-up hints can be customised to:
  • display the normal Hint text;
  • automatically display the URL, ignoring the Hint property.
  • display custom hints set each time the hint is displayed using an event handler.

A help file is provided that can inegrate with the IDE of Delphi 3 to 7.

This v2 release is backwards compatible with v1 of the component.

This unit provides a component (TPJColourPopupMenu) that can display a menu containing the sixteen common Windows colours. The menu can take various styles - text only, text with a colour bitmap, colours only (like a palette) or can be owner drawn. It can display colours in 1, 2, 4 or 8 columns. The component is most useful when linked to a toolbar button.

Comes with fully integrated help and a demo project.

DIPP is freeware, no strings attatched.

The cxpos replace function is so strong it at least 25X faster than standard delphi's StringReplace on a very light task, and raised exponentially according the weight (we might say thousands times on heavy duties, but it actually simply incomparable).

+Sample Demos (Source-code only):

SpeedTest, a benchmark suite to compare cxpos speed with others' similar libraries.

Console Apps:

• SR32 (The Real *Fast* Search/Replace),
• ScanStr (String Collector),
• Pretty (Filename Formatter).
• Extra: .DFM Converter.

Also included (though reluctantly), by the spirit of OpenSrc, another our several powerful libraries: Ordinals, fileScan, getOpts, MinMaxMid. [more]

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.
