	Adaptei o demo do Delphi (C:\Delphi7\Demos\CoolStuf\webbrows.dpr) e alterei os trecho dos codigo abaixo:
 
	procedure TMainForm.FindAddress; 
	var 
	  EncodedDataString: string; 
	  PostData: OleVariant; 
	  Headers: OleVariant; 
	  i: integer; 
	begin 
	 //   http://www.delphifaq.com/faq/delphi/network/f249.shtml 
	  // First, create a URL encoded string of the data 
	  EncodedDataString := 'userName='+HTTPEncode('Luiz Inacio')+'&'+'UserPass='+HTTPEncode('MyPassword');
 
	  // The PostData OleVariant needs to be an array of bytes 
	  // as large as the string (minus the 0 terminator) 
	  PostData := VarArrayCreate([0, length(EncodedDataString)-1], varByte);
 
	  // Now, move the Ordinal value of the character into the PostData array 
	  for i := 1 to length(EncodedDataString) do 
	    PostData[i-1] := ord(EncodedDataString); 
	  Headers := 'Content-type: application/x-www-form-urlencoded'#10#13;
 
	  // Parameters 2 and 3 are not used, thus EmptyParam is passed. 
	  WebBrowser1.Navigate('https://www.site_a_consultar.com.br', 
	                       EmptyParam, EmptyParam, PostData, Headers); 
	{ 
	 //   http://www.scalabium.com/faq/dct0139.htm 
	   p:='='+HTTPEncode(); 
	  h := 'Content-Type: application/x-www-form-urlencoded' + #10#13; 
	  UpdateCombo := True; 
	  //WebBrowser1.Navigate(WideString(Urls.Text), Flags, Flags, p, Flags); 
	  WebBrowser1.Navigate(WideString(''), EmptyParam, EmptyParam, p, h); 
	} 
	end; 
	 
 
	procedure TMainForm.WebBrowser1DownloadComplete(Sender: TObject); 
	var 
	oStringList: TStringList; 
	html : string; 
	begin 
	  { Turn the stop button grey } 
	  StopBtn.ImageIndex := 2; 
	  { Stop the avi and show the first frame } 
	  Animate1.Active := False; 
	  //https://www.clubedohardware.com.br/forums/topic/827939-como-ler-o-conteúdo-de-um-site-por-um-memo/ 
	  oStringList := TStringList.Create; 
	  try 
	    oStringList.Text := WebBrowser1.OleObject.document.Body.InnerHTML; 
	  html := oStringList.Text; 
	  except 
	  end; 
	  oStringList.Free; 
	  showmessage(html); 
	end;
 
	Espero ter ajudado. Acho que ainda dá tempo. rsrsrs    :)
