Usage: Simply drop an instance of TWebBrowser component on a form (and a Button) and call the find dialog as:
~~~~~~~~~~~~~~~~~~~~~~~~~
uses ActiveX;
procedure WBFindDialog(AWebBrowser: TWebbrowser) ;
const
CGID_WebBrowser: TGUID = '{ED016940-BD5B-11cf-BA4E-00C04FD70816}';
HTMLID_FIND = 1;
var
CmdTarget : IOleCommandTarget;
vaIn, vaOut: OleVariant;
PtrGUID: PGUID;
begin
New(PtrGUID) ;
PtrGUID^ := CGID_WebBrowser;
if AWebBrowser.Document <> nil then
try
AWebBrowser.Document.QueryInterface(IOleCommandTarget, CmdTarget) ;
if CmdTarget <> nil then
try
CmdTarget.Exec(PtrGUID, HTMLID_FIND, 0, vaIn, vaOut) ;
finally
CmdTarget._Release;
end;
except
end;
Dispose(PtrGUID) ;
end;
procedure TForm1.FormCreate(Sender: TObject) ;
begin
WebBrowser1.Navigate('http://www.delphi.about.com') ;
end;
procedure TForm1.Button1Click(Sender: TObject) ;
begin
WBFindDialog(WebBrowser1) ;
end;
