Well, basically you can hide a Plus window's close button by using code like this:

code:

---

<Window Id="WndSomeWindow" Version="1">
    <TitleBar>
        <AllowClose>false</AllowClose>
    </TitleBar>
    ...
</Window>

---

This will hide the sign.

However, you can always use scripted code to close the window, like this:

code:

---

var wndSomeWindow = MsgPlus.CreateWnd("Resources\\wndSomeWindow.xml", "WndSomeWindow");
// do other stuff
// ...
// now we decide it's time to close the window
wndSomeWindow.Close(1);

---

However, the user can always close the window by pressing Alt+F4 (unless you register a message notification callback function and suppress the window message this way).
