This is for developers , not for endusers.As you know it will irritate during developemnt since it is appearing on top of all windows when we open form.
static void hideContentPaneWindow(Args _args)
{
#WinApi
HWND contentPane = WinApi::findWindowEx(WinAPI::findWindowEx(infolog.hWnd(),
0, 'MDIClient', ''),0,'ContentFrame','' );
;
if (contentPane)
WinApi::ShowWindow(contentPane,#SW_HIDE); // To restore use #SW_RESTORE
}
