HOW TO CALL INTERNET EXPLORER FROM DELPHI


Now that Internet Explorer is a standard part of Windows NT 4.0 and future versions of Windows [95], you may find it useful to add a hot key to your program which will take the user to your home page. Here's a simple function which will do just that: 
program iexplor;

uses
  Windows, OLEAuto;


procedure OpenInternetExplorer( sURL : string );
const
  csOLEObjName = 'InternetExplorer.Application';
var
  IE        : Variant;
  WinHanlde : HWnd;
begin
  if( VarIsEmpty( IE ) )then
  begin
    IE := CreateOleObject( csOLEObjName );
    IE.Visible := true;
    IE.Navigate( sURL );
  end else
  begin
    WinHanlde := FindWIndow( 'IEFrame', nil );
    if( 0 <> WinHanlde )then
    begin
      IE.Navigate( sURL );
      SetForegroundWindow( WinHanlde );
    end else
    begin
      // handle error ...
    end;
  end;
end;

begin
  OpenInternetExplorer( 'microsoft.com' );
end.
