hi，
How to get this pop-up Window handle when opening a new page window

Try GetActiveWindow, GetForegroundWindow or EnumChildWindows.

hi,
I have found a solution like this：
var
NewBrowserHandle：hwnd；

procedure TForm1.chrm1AfterCreated(Sender: TObject; const browser: ICefBrowser);
begin
NewBrowserHandle：=browser.Host.WindowHandle；
PostMessage(Handle, BROWSER_CREATED, 0, 0);
end;

Then receive the message like this：

procedure TForm1.BrowserCreatedMsg(var aMessage : TMessage); message BROWSER_CREATED;
begin
mmo1.lines.add(inttostr(NewBrowserHandle));
end;

Is that okay？Anyway, I got the result.

Sorry, I misunderstood.

Yes, that's correct.
