I had try to overriding WindowProc and send message to ie's document handle,or setfocus to ie's document,but did not work.

Because I just want a control to browse a web page,I only spent a few hours to get this, so it is very simple. Embarassed

OK, found it.

The problem is that DHCtrl was originally designed for OpenGL widget - in that case, it was not desirable that widget would eat all event messages. That is why by default, DHCtrl is disabled (so that parent Ctrl can take over message processing, effectively returning it back to DHCtrl, because in U++, message dispatch to child widgets is done by CtrlCore).

So the one simple remedy is to:

	LRESULT hdIECtrl::WindowProc( UINT message, WPARAM wParam, LPARAM lParam )
	{
		switch (message)
		{
		case WM_SIZE:
			wb.doResize();
			break;;
		case WM_CREATE:
			wb.attach(GetHWND());
			EnableWindow(GetHWND(), true);
                        break;
		}

		return DHCtrl::WindowProc(message, wParam, lParam);
	}

Now we have to fix those Heap leaks and we have one quite useful class... (what a pity that right now, there is no Linux counterpart).
