I'd like a generalized function where I could pass any window class

close it if it is open. Something approximating this:
Function CloseWindow (W as Window)
For i as integer = (WindowCount-1) downto 0
if Window(i) isa W then Window(i).close
Next
End Function
The problem above is the compiler complains that w is not a class.
That's correct. W is not a class it's a window of a certain class
which is unknown. The isA function takes a class not an object which
would be of some class type. You could use another parameter of the
window to distinguish them. Are the Titles unique per class of
window? If not, you may need to add a property to your windows and
use that, or you can use a big case statement where you determine the
class exhaustively. AFAIK RB doesn't have introspection, I think
that's the term, where an object could tell you about itself in the
way you would need for your idea.
HTH,
Kevin
