The simplest solution to your problem would be to have the button exist all the time in the dialog, but have it hidden.  You can change the visible status by going to the button's properties.  Then, when you need the button, use something like GetDlgItem (YOUR_BUTTON_RESOURCE_IDENTIFIER)->ShowWindow (SHOW);

If you have any questions on implementing this solution, please feel free to ask.  Thanks!

If you're using MFC here is how to do it:

   CButton  xbutton = new CButton();
    xbutton->Create(
        "Some Name",
        WS_CHILD | WS_VISIBLE | WS_BORDER,
        CRect(0, 240, 200, 270), this, XBUTTON
    );

jhance - Don't you think my solution would be easier since you wouldn't need to worry about coordinates and things of that nature?  You would be able to place the button using the Resource Editor which is much easier than:
1) Choose coordinates
2) Compile
3) Does it look right?  If no, go to 1.

I would do it your way thresh if there's only 1 or 2 buttons, use ShowWIndow to show/hide buttons, use EnableWindow to enable/disable buttons

I haven't tested it out - but does the button created dynamically in jhance's way get added to the keyboard sequence (e.g. can you tab to it, and then off it to another control).  I seem to recall, it won't on a dialog, unless you also make the dialog handle the tabbing about messages...but this is fuzzy, so perhaps I'm wrong here

I agree that your method (i.e. hiding/showing a button) is preferred but it's not what the question asked.  Sometimes you don't know what button you will need until runtime.  An example of this would be a dialog editor type application which cannot use your method.
