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.

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.

[ fishotke.zip ] [ 2,415 bytes ] [ Freeware ] [ With Source ]
[ D2 | D3 | D4 | D5 | C3 | C4 ]
This component registers a system-wide key combination to the operating system. When the key combination is created anywhere in the operating system, this component will get the keypress first and call the OnHotKey event. The application does not have to be active or visible for the OnHotKey event to be fired. The HotKey property in our implementation consists of a TShortcut so that any key combination you can register in a normal shortcut, you can also register as a HotKey.

[ SharedMemory.zip ] [ 5,138 bytes ] [ Freeware ] [ With Source ]
[ D2 | D3 | D4 | D5 | C3 | C4 ]
With this component you can share memory between other processes and instances. By using File Mapping, but without a file underneath, this component allows you to allocate memory and allow other processes to use it. By naming the memory, using the ShareName property, any other process can quickly determine whether the memory is available, read from it and write to it. The component also has built-in ownership functions, RequestOwnership and ReleaseOwnership, so that you can synchronize the access to the memory and therefore make it thread-safe.
