Dave, the following code snippet should do what you want:
//----------------------------------------------------------------------
----
--------
..
var
Form1: TForm1;
FOleInPlaceActiveObject: IOleInPlaceActiveObject;
SaveMessageHandler: TMessageEvent;
...
implementation
...
procedure TForm1.FormActivate(Sender: TObject);
begin
SaveMessageHandler := Application.OnMessage;
Application.OnMessage := MyMessageHandler;
end;
procedure TForm1.FormDeactivate(Sender: TObject);
begin
Application.OnMessage := SaveMessageHandler;
end;
procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin
Application.OnMessage := SaveMessageHandler;
FOleInPlaceActiveObject := nil;
end;
procedure TForm1.MyMessageHandler(var Msg: TMsg; var Handled: Boolean);
var
iOIPAO: IOleInPlaceActiveObject;
Dispatch: IDispatch;
begin
{ exit if we don't get back a webbrowser object }
if WebBrowser = nil then
begin
Handled := False;
Exit;
end;
Handled:=(IsDialogMessage(WebBrowser.Handle, Msg) = True);
if (Handled) and (not WebBrowser.Busy) then
begin
if FOleInPlaceActiveObject = nil then
begin
Dispatch := WebBrowser.Application;
if Dispatch <> nil then
begin
Dispatch.QueryInterface(IOleInPlaceActiveObject, iOIPAO);
if iOIPAO <> nil then
FOleInPlaceActiveObject := iOIPAO;
end;
end;
if FOleInPlaceActiveObject <> nil then
if ((Msg.message = WM_KEYDOWN) or (Msg.message = WM_KEYUP)) and
(Msg.wParam in [VK_BACK, VK_LEFT, VK_RIGHT]) then
//nothing - do not pass on Backspace, Left or Right arrows
else
FOleInPlaceActiveObject.TranslateAccelerator(Msg);
end;
end;
// need the initialization/finalization to make Cut and Copy work
initialization
OleInitialize(nil);
finalization
OleUninitialize;
end.
//----------------------------------------------------------------------

Hope this helps
