How do I get the URL and change the active tab in Google Chrome

This is a EE solution for IE, but I think it also should work with GOOGLE CHROME if you pass its window handle:

https://www.experts-exchange.com/questions/20271021/Get-url-for-all-opened-web-pages.html

First, you have to replace function FindIExplorer with you own function FindGoggleChrome to get the right window handle.

After that you can check functionality...

Hello Thommy

I use this method but it did not work in chrome

procedure GetCurrentURL(url,Title: string);
var
   DDEClient : TDDEClientConv;
   p, q: PChar;
   i: Integer;
begin
   DDEClient := TDDEClientConv.Create(nil);
   try
     with DDEClient do if SetLink('IExplore', 'WWW_GetWindowInfo') or
       SetLink('Netscape', 'WWW_GetWindowInfo') or
       SetLink('Mosaic', 'WWW_GetWindowInfo') or
       SetLink('Netscp6', 'WWW_GetWindowInfo') or
       SetLink('Mozilla', 'WWW_GetWindowInfo') or
       SetLink('Firefox', 'WWW_GetWindowInfo') then
       p := RequestData('0xFFFFFFFF')
     else raise Exception.Create('Could not establish browser DDE link');
     if Assigned(p) then try
       q := p;
       Assert(q^ = '"');
       SetLength(URL, StrLen(q));
       Inc(q);
       i := 0;
       while q^ <> '"' do begin
         if (q^ = '\') and (q[1] = '"') then Inc(q);
         Inc(i);
         URL[i] := q^;
         Inc(q);
       end;
       SetLength(URL, i);
       SetLength(Title, StrLen(q));
       i := 0;
       Inc(q, 3);
       while q^ <> '"' do begin
         if (q^ = '\') and (q[1] = '"') then Inc(q);
         Inc(i);
         Title[i] := q^;
         Inc(q);
       end;
       SetLength(Title, i);
     finally
       StrDispose(p);
     end else raise Exception.Create('Could not fetch browser data');
   finally
     DDEClient.Free;
   end;
end;

This will return url of active GOOGLE CHROME tab:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Memo1: TMemo;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;
  TheHandle:THandle;

implementation

{$R *.dfm}

function GetGoogleActiveTabAddress(wnd: THandle; Param: Integer): Bool; stdcall;
var
 wndClass: array[0..127] of char;
 len:integer;
 h:hwnd;
 S:string;
 i:integer;
begin
 //Get the object class name.
 GetClassName(wnd, wndClass, SizeOf(wndClass));

 if (wndClass = 'Chrome_AutocompleteEditView') then begin
   h:=FindWindowEx(TheHandle,0,wndClass,nil);

   len:=SendMessage(h, WM_GETTEXTLENGTH, 0, 0);

   SetLength(S, len);

   SendMessage(h, WM_GETTEXT, len+1, lparam(@S[1]));

   for i:=1 to length(S) do begin
     SendMessage(Param, WM_CHAR, ord(S[i]), 0); //Paste from the ClipBoard to the Memo1.
   end;
   SendMessage(Param, WM_CHAR, 13, 0); //Send ENTER to the Memo1.



 end;
 Result := True;                               //Continue searching.
end;

function FindGoogleChrome(wnd: THandle; Param: Integer): Bool; stdcall;
var
 wndClass: array[0..127] of char;
begin
 //Get the object class name.
 GetClassName(wnd, wndClass, SizeOf(wndClass));

 if wndClass = 'Chrome_WidgetWin_0' then begin
   TheHandle:=wnd;
   EnumChildWindows(wnd, @GetGoogleActiveTabAddress, Param); //Enum the child objects.
 end;
 Result := True; //Continue searching other IExplorer windows.
end;


procedure TForm1.Button1Click(Sender: TObject);
begin
  EnumWindows(@FindGoogleChrome, Memo1.Handle);
end;

end.

Hello

thank you very very much tommy.

Concerning your second question of how to change active tabs:

You can change Tabs in Google Chrome by pressing key combination CTRL+1 for first tab, CTRL+2 for second tab and so on.

We can use PostMessage to send keys to Google Chrome...

thank you Thommy

How to PostMessage with the active tab to send the ur ?l. Can you give an example ?

Best Regards

Hello

Thank you very much tommy

Thank you very much for the points!!!

Do you already have a solution for sending key combinations like CTRL-1, CTRL-2 and so on to GOOGLE CHROME for changing active tabs???
