怎么捕获BeforeNavigate和DocumentComplete来获取打开页面用的时间？ 
具体代码该怎么写？急！！！ 
 
 


------解决方案--------------------
int mytime=0;
int mytime1=0;

void __fastcall TForm1::CppWebBrowser1BeforeNavigate2(TObject *Sender,
LPDISPATCH pDisp, Variant *URL, Variant *Flags,
Variant *TargetFrameName, Variant *PostData, Variant *Headers,
VARIANT_BOOL *Cancel)
{
mytime=GetTickCount();
}
//---------------------------------------
void __fastcall TForm1::CppWebBrowser1DocumentComplete(TObject *Sender,
LPDISPATCH pDisp, Variant *URL)
{
mytime1=GetTickCount();

}

mytime1-mytime就是BeforeNavigate和DocumentComplete之间的毫秒
------解决方案--------------------

C/C++ code

//---------------------------------------
void __fastcall TForm::Chart1MouseMove(TObject *Sender,TShiftState Shift, int X, int Y)
{
  double xv,yv,pp,yy;
           xv=Chart1->Series[4]->XScreenToValue(X);
          yv=Chart1->Series[4]->YScreenToValue(Y);

}
