Event COM interface defined as
[ComVisible(true)]
[Guid("C9F4436D-0795-4604-8A80-CA36CC9611FE")]
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface ISimpleSource
{
[DispId(1)]
void SimpleEvent(string msg);
}
My class is defined as
[ComSourceInterfaces(typeof(ISimpleSource),typeof(IMweSource))]
[ClassInterface(ClassInterfaceType.None)]
[ComVisible(true)]
[Guid("7454BE8B-287E-4032-9657-B2B5C36A6BB5")]
public partial class MweCtrl : UserControl, IMweCtrl1
{
...
[ComVisible(false)]
public delegate void SimpleTarget(string msg);
public event SimpleTarget SimpleEvent;
private void button1_Click(object sender, EventArgs e)
{
if (SimpleEvent != null)
SimpleEvent("Event msg!");
}
...
}
By debugging I've come to the conclusion that the ActiveX Control Test
Container successfully registers with the SimpleEvent where as VB6 seems
not to. When running from VB6 SimpleEvent is null, i.e. no one is listening
in that case. So I guess the real question is how to make VB6 register for
the event.
Kind regards,
