Question WebBrowser still 'active' when form is closed

[gchq]

Hi there

On a dynamic form a WebBrowser control connects to a Media Player on one of our servers.

After the form is closed the audio is still running even though the FormClosed event is handled...

Private Sub Formclose_click(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosedEventArgs)
        UtilForm1.Controls.Clear()
        UtilForm1.Dispose()

            End Sub

Any ideas?

Thanks

Controls.Clear() causes the controls to be removed, but not disposed. Disposing the form (though using Close method would be more natural) will automatically dispose child controls. If this FormClosed handler is for same "UtilForm1" reference you don't need any of those calls.

Hi John

Thanks for the reply

The form is a opened via ShowModal, so closing only 'hides' the form - I would have thought that calling Form.Dispose would have sorted the issue, but the whole application has to be closed before the streamed audio shuts off...


And yes - the control was added to Utilform1.

ShowModal

ShowDialog you mean, true, but then caller should call Dispose when ShowDialog returns. But as I said, don't remove the controls without disposing them, disposing the form also disposes the controls (when they still belong to form).

ShowDialog you mean,...

Indeedy doooo Bouncing back and forth from asp.NET causes brain farts and loss of direction....

..don't remove the controls without disposing them..

There is always something to learn.

Thanks John
