I loaded a page in my program using TCppWebBrowser, that cointais these 
lines (among many others):

<a href="javascript: confirmarInformacoesDeVisto();">
<img src="bt_voltar.gif" border="0"></a>&nbsp;

<a href="javascript: confirmarAgendamento();">
<img src="bt_confirmar.gif" border="0"></a>&nbsp;

<a href="javascript: listaSituacaoAgendamento();">
<img src="bt_cancelar.gif" border="0"></a>


How can I execute by program the second line?
I mean, how can I "simulate" by my program the click of the mouse in the 
specified link by a user?

I saw a code on another post that execute a "click" on a button (by Remy).

#include <mshtml.h>
#include <utilcls.h>

if( CppWebBrowser1->Document )
{
   TComInterface<IHTMLDocument2> Doc;
   CppWebBrowser1->Document->QueryInterface(IID_IHTMLDocument2, 
(LPVOID*)&Doc);

   if( Doc )
   {
     TComInterface<IHTMLElementCollection> All;
     Doc->get_all(&All);

     if( All )
     {
       TComInterface<IDispatch> Disp;
       All->item(TVariant(WideString("secure_exit")),
TVariant(0), &Disp);

       if( Disp )
       {
         TComInterface<IHTMLElement> Element;
         Disp->QueryInterface(IID_IHTMLElement,
(LPVOID*)&Element);

         if( Element )
	  Element->click();
       }
     }
   }
}

But in this example, the "button" has a name,

<input TYPE="button" NAME="secure_exit" VALUE=" Finished "
onClick="logout();">

And my "links" don't have...
So, how to FIND the right link in the page and how to execute it?

I saw in another post (that I can't remember where), that Javascript can 
be put in Navigate like a URL...

So I don't need to find my links, I need only to execute a new Navigate 
to that link...

Like:

Browser->Navigate(WideString("javascript: myfunc()"));

But anyway, how to find the links in the page?

Thanks :)
