Tab and Delete keys don't work with TWebBrowser

hi,
yes it is a problem ,there are many oher probs with TWebbrowser and it is really better to use the TEmBeddedWb from :
http://www.euromind.com/iedelphi/
it has way better event handling capabilities ..
even cut'n'pate play up with twebbrowser

as for the twebbrowser you can still use t if you wish but it will need an event handler similar to below:
(also similar to what you would find at henry fourniers site).

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, OleCtrls, SHDocVw_TLB,ActiveX;

type
  TForm1 = class(TForm)
    WebBrowser1: TWebBrowser;
    Button1: TButton;
    OpenDialog1: TOpenDialog;
    procedure Button1Click(Sender: TObject);
    procedure FormClose(Sender: TObject; var Action: TCloseAction);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
   OIPAO  : IOleInPlaceActiveObject;
   OIPAO_Wnd:HWND;

  public
    { Public declarations }
    procedure MyMessageHandler(var Msg: TMsg; var Handled: Boolean);
  end;

var
  Form1: TForm1;
  SaveMessageHandler: TMessageEvent;
implementation

{$R *.DFM}

procedure Tform1.MyMessageHandler(var Msg: TMsg; var Handled: Boolean);
const
  DuplicatedKeys: set of Byte = [VK_TAB, VK_BACK, VK_LEFT, VK_RIGHT, VK_UP, VK_DOWN, VK_PRIOR, VK_NEXT];
var
   w:HWND;
begin
     Handled:=False;
     if Msg.message = WM_KEYDOWN then
     begin
          if Msg.wParam in DuplicatedKeys then
         //do nothing let ie take care of it
           end;
     w:=GetFocus;
     if (w=0) {or (w=[].Handle)} then Exit;
     if OIPAO<>nil then
     begin
          if w = OIPAO_Wnd then Handled := IsDialogMessage(w,Msg);
          if not Handled then Handled := (OIPAO.TranslateAccelerator(Msg) = S_OK);
     end;
     if (not Handled) and Assigned(SaveMessageHandler) then SaveMessageHandler(Msg,Handled);
 end;

procedure TForm1.FormCreate(Sender: TObject);
var
   Dispatch:IDispatch;
begin
    if assigned(WebBrowser1) then
     begin
          Dispatch := WebBrowser1.Application_;
          if Dispatch<>nil then
          begin
               Dispatch.QueryInterface(IOleInPlaceActiveObject, OIPAO);
          end;
          if OIPAO <> nil then OIPAO.GetWindow(OIPAO_Wnd);
     end;
     SaveMessagehandler := Application.OnMessage;
     Application.OnMessage:=MyMessageHandler;
 end;

procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin
OIPAO := nil;
Application.OnMessage := SaveMessageHandler;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
opendialog1.execute;
webbrowser1.OleObject.navigate(opendialog1.filename);
end;

initialization
  OleInitialize(nil);

finalization
  OleUninitialize;

end.

Hi,

Many thanks for the code.  I'll take a look at EmbeddedWB too.
