Jedi Code Library JCL JVCL 组件包 JCL+JVCL超过300个组件的非可视/可视大型组件包。

unit fInstall;

{
  This is a simple installer showing you how to use those
  components. Those components are just interfaces for the installer,
  Jvt they doesn't decompress/create links and other stuff's like that !.

  For creating links, use the  TJvCreateShortcut in the Jv Utils palette,
  and to decompress something, use the TJvCabFile component  in the Jv Utils2
  palette.

  This sample doesn't modify anything on your system ! You can run it
  without any problem, the installation progress is simply a fake
  random loop.

  To enable uninstall features, look at the end of the code, I explain
  you how to use my components to do such a thing, and of course, you'll
  have to create an uninstaller using the TJvUninstaller component
}
