	Component: TChangeMonitor  Version: 1.1  Delphi: 2.x, 3.x  Platforms: Windows 95 and Windows NT 4.0 and above.  Description: TChangeMonitor component can watch Microsoft Windows' special folders. Among the folders on which watch can be initiated are:  Desktop Fonts Network Neighborhood Personal Programs Recent Documents Send To Start Menu Startup Templates Favorites An OnChange event is generated when the folder, on which watch was kept, changes. TChangeMonitor can detect changes in the following:  Creating a file in the folder. Renaming a file in the folder. Deleting a file in the folder. Creating a directory in the folder. Renaming a directory in the folder. Deleting a directory in the folder. An attribute (Readonly, Hidden, Archive, System) of the folder. Modifying a file in the folder. A file's last write-time. Effectively, all modifications to files and directories, including renames, creations and deletions, can be detected.   Along with the component, the unit includes functions that provide information about the actual location of special folders in the file system.
	Component: TFileChange   Version: 1.1 (Windows 95, Windows NT)  Version: 2.0 (Windows NT 4.0 onwards)  Delphi: 2.x, 3.x  Description: TFileChange component can watch file system objects. An OnFileChange event is generated when there is any change in the folder on which watch was initiated. A folder is said to have changed when any of the following happens:  Creating a file in the folder. Renaming a file in the folder. Deleting a file in the folder. Creating a directory in the folder. Renaming a directory in the folder. Deleting a directory in the folder. An attribute (Readonly, Hidden, Archive, System) of the folder. Modifying a file in the folder. Under Windows NT, a whole directory-tree can be monitored. TFileChange 2.0 can also provide information on what has changed.
	Component: TAnimate  Version: 1.1  Delphi: 1.x, 2.x  Description: TAnimate component, as the name suggests, show animation effects. It can show frames in a bitmap in successive order. The bitmap can be created using the FilmstripBuilder provided with the registered version. TAnimate component can be used to produce displays like scrolling marquees (both horizontal and vertical directions), animation, etc.  The registered version includes TAnimate component along with its threaded counterpart, TAnimateThread, TAnimate FAQ, Sample Demo files, Sample bitmaps for use with the component and a filmstrip builder with which you can create bitmap usable by the component.  Bitmaps: Click here to download bitmaps that can be used with TAnimate and TAnimationThread component.
	Component: TAnimateThread  Version: 1.1  Delphi: 2.x  Description: TAnimateThread is the threaded version of the TAnimate component. It runs the animate in its own thread. This has a number of advantages: First, it does not use timers which is a costly resource in Windows. Second, animations faster than 18 frames per second are now possible.  The registered version includes TAnimateThread component along with its timer-based counterpart, TAnimate, TAnimateThread FAQ, Sample Demo files, Sample bitmaps for use with the component and a 32-bit filmstrip builder with which you can create bitmap usable by the component.  Bitmaps: Click here to download bitmaps that can be used with TAnimate and TAnimateThread component.
	Component: TLabel3D  Version: 1.1  Delphi: 1.x, 2.x  Description: TLabel3D supports all the properties associated with TLabel component. In addition it sports a 3D look with font effects like Inset and Raised, a 3D border (Bevel width, border style, border width, etc.) and Vertical alignment.  Sample: Click here to see a sample of the kind of effects TLabel3D produces.

Component: TWavePlayer  Version: 1.0 (Source included)  Delphi: 1.x, 2.x, 3.x  Description: TWavePlayer component can play a wave file (.wav) to the default wave device. On the event of non-availability of the wave file, it can, optionally, play a default sound (set through the Control Panel - usually a beep). It can either make the calling process wait for the wave file to finish playing or it can play the file asynchronously. It can stop any currently playing wave file. Optionally, it can loop over endlessly without any further intervention. See Also: TWavePlayer 2.0

Freeware utility units:
