[CDN (Content Delivery Network)]

It would be great to move all static file (especially ExtJS) to a different domain and use CDN (Content Delivery Network) on this domain.

I would move all static files (including and especially ExtJs) to CDN (Content Delivery Network). Is it possible? If yes, the how?

[Extra UniGUI Components]

Thank you very much for updates!

 

Wishes: add support for run time changes of Enabled and Visible properies for Popup menu items.

[TUniURLFrame in VCLMode]

I'll answer myself.

 

1. Search a child window of the Frame.VCLContainer.Handle with the 'Internet Explorer_Server' class.

2. Get IHTMLDocument2 and IWebbrowser2 interfaces using the following code:

 

function GetIEFromHWND(WHandle: HWND; var pDoc: IHTMLDocument2; var IE: IWebbrowser2): HRESULT;
var
  hInst: HWND;
  lRes: DWORD;
  Msg: Integer;
  ObjectFromLresult: TObjectFromLresult;
begin
  hInst := LoadLibrary('Oleacc.dll');
  if hInst=0 then
   begin
    Result := GetLastError;
    exit;
   end;

  @ObjectFromLresult :=  GetProcAddress(hInst, 'ObjectFromLresult');
  if @ObjectFromLresult <> nil then
  begin
    try
      lRes := 0;
      Msg := RegisterWindowMessage('WM_HTML_GETOBJECT');
      if SendMessageTimeOut(WHandle, Msg, 0, 0, SMTO_ABORTIFHUNG, 1000, @lRes)<>0 then
       begin
        Result := ObjectFromLresult(lRes, IHTMLDocument2, 0, pDoc);
        if Result = S_OK then
          (pDoc.parentWindow as IServiceprovider).QueryService(IWebbrowserApp,
            IWebbrowser2, IE);
       end
      else
       Result := GetLastError;
    finally
      FreeLibrary(hInst);
    end;
  end
  else
   Result := GetLastError;
end;

It allows you fully control the web frame from the VCL mode.

 

Note: The 'Internet Explorer_Server' child window will be available only after you'll load something to the frame.

[TUniURLFrame in VCLMode]

But may be, is it possible in the current version in any kind?

[TUniURLFrame in VCLMode]

I load a HTML page to the TUniURLFrame component in VCL mode. I would catch "onclick" events on some objects of the loaded HTML page in my program. Is it possible?

[Производительность]

Кто-нибудь оценивал производительность приложений через веб с использованием unigui. Планирую развернуть на публичном сервере. Сколько одновременных клиентов выдержит? Какая система нужна для этого?

Датасеты используются, но очень мало. Буду признателем, если кто поделится опытом.
