Question

以下代码未关闭Internet Explorer 8中的选项卡。如果我将Wm_close命令发布到Wnd，它会关闭Internet Explorer，但我想关闭当前选项卡而不是整个'ieframe'。 FindWindowEX（Wnd，0，'Frame Tab'，nil）是否应该重新设置一个句柄即框架？如果是，为什么不关闭Internet Explorer中的当前选项卡？

var
   Wnd, WndChild : hwnd;
begin
   Wnd := FindWindow('IEFrame', nil);
   WndChild := FindWindowEX(Wnd, 0, 'Frame Tab', nil);
   postmessage(WndChild, wm_close, 0, 0);
end;

你错过了1层，标签本身，除此之外，它很好......

var
  Wnd, WndChild: THandle;
begin
  Wnd := FindWindow('IEFrame', nil); // Top most IE
  if Wnd > 0 then
  begin
    WndChild := FindWindowEx(Wnd, 0, 'Frame Tab', nil); // Tabs holder
    if WndChild > 0 then
    begin
      WndChild := FindWindowEX(WndChild, 0, 'TabWindowClass', nil); // top most tab
      if WndChild > 0 then
        if PostMessage(WndChild, WM_CLOSE, 0, 0) then
          ShowMessage('Close request succeeded...')
        else
          ShowMessage('Failed!');
    end
    else
      // not tabbed, close IE
        if PostMessage(Wnd, WM_CLOSE, 0, 0) then
          ShowMessage('Close request succeeded...')
        else
          ShowMessage('Failed!');
  end
  else
    ShowMessage('No IE');
end;

var
  hie,
  hftab,
  htab : DWORD;
begin
  hie := FindWindow('IEFrame', nil);
  hftab := FindWindowEx(hie, 0, 'Frame Tab', nil);
  htab := FindWindowEX(hftab, 0, 'TabWindowClass', nil);
  PostMessage(htab, WM_CLOSE, 0, 0);
  CloseHandle(hie);
end;`
