This is an invisible component with a simple task to split a file into multiple files of certain size. The most common need for this is when you want to put your (big) file on floppy disks, for backup or any other purposes. The method for reversing the process, the unsplitting, is also icluded. Version 1.03 - added a property to reduce the size of the first split file.
Built and tested using Delphi versions 3,4 and 5, but it should work with all Delphi and C++ Bulder versions.

Use the MS Word COM interface to provide spelling and grammar checking in your application! Many target platforms already have MS Word installed and the powerful spelling engine can be accessed through OLE interface calls. For simplicity, late binding is used (allowing Word 97 or 2000 to be used easily). Text from any source (eg: RTF) that can be copied to a MS Word document can be checked using the CheckClipboard.. functions and all the power of languages / custom dictionaries can be accessed via MS Word's normal dialog boxes.

Version 2.3 provides a couple of new features:
i) Select the Language MS Word uses for spell checking
ii) Allows the changing of the caption on the Spelling Error dialog
iii) Provides a simple function to check if Word is installed on the host machine (just checks registry)
iv) Provides a flag to indicate if the user has cancelled the MS Word Spelling / Grammar Dialog

I've come across so many components with system information, some lack in one area, where others lack elsewhere. So having got fed up with this, I decided to write a component that would contain EVERYTHING. Now this contains about 95% of all the system paths available (I think). The ones I've left out have been left out because I didn't think they would be needed.

TBinaryData and TCompressedBinaryData are two components to embed data into your forms or datamodules. Simply drop the component and double click on it, then select the file you want to embed and that's all. You can save the data later to a file, or use directly in memory trhu a TMemoryStream. In the case of TCompressedBinaryData it uses the ZLib unit (included with Delphi) allowing the user to compress the data to save space in the final executable.

These components will scan a given dir and generate an event each time a new file or directory is found or added. TDADirScan will just scan the directory TDADirScanTreeView will fill a treeview with its content TDADirScanListView will fill a listview You can subclass TDaDirScan if you want other components to be filled. This component will allow you to separate the content (in this case : file system) from the way it is represented (treeview, listview or other).

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 DSP and 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 to 7. It does not integrate with the Delphi 1, 2 and 2005 or later IDEs but can be used independently of the IDE.

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. New demo program also added.

This code defines a property editor for properties of type HKEY - i.e. registry root keys. The editor causes a drop-down list of all the registry root keys supported by Delphi to be displayed in the object inspector for any property of type HKEY.

Such a property is exposed by my TPJRegWdwState component (available on DSP or from my website). This property editor is included with current releases of that component.

v1.0.2 adds support for Delphi 6 & 7.

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.

Tested on Delphi 4, 6, 7 and 2006.

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.

A 16 bit version of the component is available from the author's website.

TPJWdwState and TPJRegWdwState are a pair of non-visual components that can save and restore a window's size, position and state between program executions. Key features are:

  • The components can automatically restore and save window state when the program starts up and closes down.
  • The user can provide an event handler to change the stored window's state, size and position values before the window is restored.
  • The components can be instructed to always display a window in the normal state regardless of the saved state.
  • The window's saved size can be ignored and the form's design size used (useful for dialog boxes and fixed size windows).
  • The window can be kept within the current work area of the desktop.

TPJWdwState stores window information in an ini file while TPJRegWdwState uses the Windows registry.

A help file is included that integrates into the Delphi 3-7 OpenHelp system and can be used stand-alone with Delphi 2005 and later.

A property editor is provided for editing HKEY values (such as the registry root key property of TPJRegWdwState). This editor is also available separately.
