Hello all!

I have a .NET form which primarily contains a legacy ActiveX control. I was
wondering if it is really worth claling ReleaseComObject on this control from
the form's dispose method.

Public Overrides Sub Dispose(ByVal disposing As Boolean)
If Not AxDatabaseControl Is Nothing Then
System.Runtime.InteropServices.Marshal.ReleaseComObject(AxDatabaseControl)
End If
End Sub

Should I bother to call ReleaseComObject? Am I the better for it?

Hi Kevin,
I think you must call it because the garbage collector does not dispose the
activex / com component. Just be safe by calling it !
