Hi all,
i need creating a new WebBrowser deriving from TCppWebBrowser, so that i did 
as follows, but
running, i'm getting  AccessViolation error while  executing line
web->Navigate(WideString("http://www.qrz.com"));
Any idea what's doing wrong or missing ?
Thanks
Gio

UNIT1.H
......................
class webnew : public TCppWebBrowser
{
__published: // IDE-managed Components
private: // User declarations
public:  // User declarations

        __fastcall webnew(TComponent* Owner);
};

UNIT1.CPP
.................
__fastcall webnew::webnew(TComponent* Owner)
        : TCppWebBrowser(Owner)
{

}
//---------------------------------------------------------------------------
void __fastcall TForm1::FormShow(TObject *Sender)
{
 web=new webnew(this);
 web->ParentWindow = Form1->Handle;
 web->Height = Form1->Height;
 web->Width = Form1->Width;
 web->Visible = true;
 TWinControl(web).Parent=Form1;                // ALL OK so far
 web->Navigate(WideString("http://www.qrz.com")); // HERE rise 
EAccessViolation error

Do it this way:

web->Navigate(WideString("http://www.qrz.com").c_bstr());

Thanks Shao,
it doesn't work although, instead if i set
web->Navigate(WideString"").c_bstr())   or     web->Navigate(WideString(""))
error doesn't arise, but no link of course.
It seems the problem arise in handling url parameter.
Thanks anyway.
Giorgio
