Close visible form as new menu item chosen

[chapm4]

Dumb question as it seems I have a lot of.....I have an app using mdi dropdown menu's that open various forms. When a new item is chosen, I want the old window to close (If the user did not use the quit button on the form). How do I do this and where?

maybe you should not be using MDI for your application. Remember M in MDI stands for Mutiple.

Anyway, here is one way to do it. (Although I think there is a proper way, but do not remember what it is.)

Private frmActive As Windows.Forms.Form

...

Private Sub MenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem1.Click

Try
frmActive.Close()
Catch
End Try

Dim x As New frmColorText()
frmActive = x
x.MdiParent = Me
x.Show()

End Sub

This will close the last window of the same menuitem that was opened. Add this to each menuitem with the same variable and it will keep only one window open at a time.
