using handles to get RichEdit text

[shaharM123]

Read MSDN on GetWindowText () ...

I tried using the SendMessage:

char txt[512]="";
::SendMessage(hwndRichEditControl1 ,WM_GETTEXT,512,(LPARAM)txt);

But even this doesn't work.. any ideas?

I'm using winID to watch this control and I can see the text under "Title" property.
Its class is WindowsForms10.RichEdit20W.app.0.33c0d9d.

Why can't I retrieve the text with SendMessage(..., WM_GETTEXT, ...)??
