This is web page that contains a COM control written in Delphi 3. When the control is downloaded and instantiated, it plays a sound.
Because the control is not CodeSigned, you won't be able to install the control without setting the Internet Explorer security settings to Low to allow running unsigned controls. If you're nervous about downloading unsigned ActiveXes, download the source code below, and build it yourself using Delphi 3.
The control is minimal, and takes only about 50K of code, and no packages. In this case, the control is 83K because it includes a WAV file which it plays when created on the page. The downloadable .CAB file is only 60K (38K without the sound).
The point of this exercise is to demonstrate that it's possible to build tiny non-visual controls in Delphi.
