This unit contains classes that encapsulate Windows 32 bit binary resource files and the resources contained in them. The main functionality is provided by two classes:

  1. TPJResourceFile # encapsulates the contents of a whole resource file and provides methods and properties for reading, finding, editing, adding and deleting resources. Resource files can be read from and written to files or streams.
  2. TPJResourceEntry # encapsulates a single resource within the file and provides properties to access its header record and its raw data. The class also provided methods to check the identity of the resource. The resource's raw data is made available as a TStream and so is easily read and written using familiar TStream methods.

Note that the classes have no knowledge of resource data formats and see the resource data simply as a raw sequence of bytes. It is for the user of the class to interpret the data correctly.

In addition to the two main classes, some useful helper functions and constants are also provided.

The download includes a UserGuide that provides detailed description of the classes, along example code for the key methods.

This is a redone from MAS-CompMaker (copyright # 2000 by Mats Asplund.) This wizard integrates nice with the Delphi IDE. It puts a new item in the Component menu called 'New AFComponents...' and it works like the standard Delphi component creation wizard. With this wizard you can easily build a component-skeleton ready to register with Delphi. Handles both ordinary and compound-components. The wizard lets you add nice comments to your components. The compound-classes used by this wizard are in the file compound.pas created by Thomas Quester

The component "DKFileFinder" is a basic file search component which will search for files that match the specified "mask". It will also search recursively within sub-folders. The code is not particularly clever but I find it very useful. I have included the .pas file so that developers can just use the code if they so wish. There are no limitations on the use of this FREE component but, by the same token, I can not except responsibility if anything goes wrong.

.NET frameworks is nice indeed. I like it, and I am a Delphi "integralist". Unfortunately, someone in MS decided that interface name prefix 'I' is good but class name prefix ('T' or 'C') it is not. This decreases immensely code clarity. C# chaps have a case- sensitive solution: they uncapitalize the instance names, e.g. graphics= new Graphics Very readable indeed! Not to mention the problem if the instance is visible outside the assembly (.NET in general is NOT case-sensitive). Delphi would have the solution: type equivalence, e.g. type TGraphics = System.Drawing.Graphics; var Graphics: TGraphics; but manually rename all framerwork types is not an option. Fortunately, using reflection it is quite easy to develop a tool that inspects an assembly and generate the type definitions automatically.

This component encapsulates an About Box in a non-visual component. It has various string properties to display five different pieces of information in the about box.

Alternatively, the about box can display information extracted from the program's version information resource. This is accessed using a linked TPJVersionInfo component -- available from my website.

Note: The TPJVersionInfo component must be installed before this component.

The About box also displays an icon. This is the icon defined for the application (see the Icon property of TApplication). If no icon has been specified for the application the default Delphi icon is used.

The display attributes and location on the screen can also be customised.

A help file is included that integrates into the IDE for Delphi 3 and later. It does not integrate with the Delphi 1 and Delphi 2 IDEs but can be used independently.

v3.3 adds a new Position property to enable the dialog to be aligned to the screen, the desktop work area or the parent form.

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.

DIPP is a Pascal Pre-Processor to manipulate Pascal source code files:
  • remove comments
  • process compiler directives
  • strip or keep conditional compiler directives by wild card masks
  • insert, read, or skip include files by wild card masks
DIPP is useful to
  • simplify debugging by inserting include files and removing unnecessary conditionals
  • prepare Pascal sources to share with 3rd parties
  • target Pascal sources at specific compiler versions
  • remove conditionals unsupported by some (old) compilers
DIPP is a tiny console application suitable for batch processing. It reads, processes and writes one file at a time, performing minimal syntax check as it goes. Output files can then be passed on to Pascal compilers.

DIPP is freeware, no strings attatched.
