Applies to HTML Viewer, IE Browser publications.
HEScript scripts are especially designed to control the publication’s behavior and to communicate with the environment (runtime module, Windows…).
You have a lot of internal functions or macros that can be called from within the HEScript script functions/procedures.

uses Classes;
To use the TRegistry object, define the Registry unit at the top of your scripts:
uses Registry;
For instance, the following script lets you remove a registry key:
uses Registry;
procedure Test1;
var
reg: TRegistry;
begin
reg := TRegistry.Create;
reg.RootKey := HKEY_LOCAL_MACHINE;
reg.DeleteKey("Software HEViewer Coucou");
reg.CloseKey();
reg.Free;
end;
