After lots of times trying I found that there are three issues you must to know:

• The parent of hidden tray window is NotifyIconOverflowWindow, other than Shell_TrayWnd.
• You shouldn't use caption parameter of FindWindowEx to find a window, because these is lots of langue versions of Windows OS, they are not always be the same title Obviously.
• Use spy++ of Visual Studio to find or make assurance what you want.

So, I changed code from @Stephen Klancher and @Louis Davis, thank you guys.

The following code worked for me.

#define FW(x,y) FindWindowEx(x, NULL, y, L"")
void RefreshTaskbarNotificationArea()
{
    HWND hNotificationArea;
    RECT r;
    GetClientRect(hNotificationArea = FindWindowEx(FW(NULL, L"NotifyIconOverflowWindow"), NULL, L"ToolbarWindow32", NULL), &r);
    for (LONG x = 0; x < r.right; x += 5)
    {
        for (LONG y = 0; y < r.bottom; y += 5)
        {
            SendMessage(hNotificationArea, WM_MOUSEMOVE, 0, (y << 16) + x);
        }
    }
}
