Detecting when a form is closed

I need to enable and disable some functions in my application depending on if a particular form is open or closed. How can I detect that the user has closed the form without making it modal?

One approach might be to examine your project's Forms collection, which contains a reference to all the loaded forms in your project. Check for the name of the form - if you find it the form is loaded. Keep in mind that a form can be loaded and not shown.
<PRE>For intIndex = 0 To Forms.Count - 1
If Forms(intIndex).Name = strNameOfTargetForm Then
' strNameOfTargetForm is loaded.
' Do whatever.
Else
' strNameOfTargetForm is not loaded.
' Do whatever.
End If
Next intIndex</PRE>

You could put the detection routine in a timer event on the main (or MDI) form.

Or you could just put the code in the unload events in the specified forms.
