Could you give us an example? Do you mean a modal dialog box, like this:

or do you mean that you want a Plus! window created by MsgPlus.CreateWnd to be a modal of another (Plus!) window?

In the first case, you can simply use the MessageBox function. You can easily find an example when searching these forums.

In the second case, you'll have to do it in a dirty way. That is, when you open your "modal" window, you disable your parent window with EnableWindow and re-enable it when you close it (in the OnWindowIdEvent_Destroyed event). I don't know if it's possible to set the focus to your modal window when you try to enable the parent window through a click or something, maybe you should experiment with that?
