Wouldn't it be cool to have a hot key in your program that can activate and load a particular page (your home page on the web for example) into Netscape Navigator? Here's how:
program Netscape;

uses
DDEMan;

procedure GotoURL( sURL : string );
var
dde : TDDEClientConv;
begin
dde := TDDEClientConv.Create( nil );

with dde do
begin
{ specify the location of netscape.exe }
ServiceApplication :=
'c:ns32programnetscape.exe';

{ activate the Netscape Navigator }
SetLink( 'Netscape', 'WWW_Activate' );
RequestData('0xFFFFFFFF');

{ go to the specified URL }
SetLink( 'Netscape', 'WWW_OpenURL' );
RequestData(
sURL+',,0xFFFFFFFF,0x3,,,' );

{ ... }Advertisement


CloseLink;
end;

dde.Free;
end;

begin
GotoURL(
'http://www.abc.com/tips/' );
end.
