Hi all,
I built a testing component using .NET (C#). I try to invoke it from SWT.
Everthing works fine except for event handling. It seems that my assembly
recognize that a listener is connected to it but I get an exception from the
..NET side when it tries to return back the control to my plug-in (I think).
Someone else has experienced the same problem?
Thanks!

Finally got the twist. Hope this partial code helps someone...
Partial Plug-In Code in Java
webControlSite = new OleControlSite(frame, SWT.NONE,
"MyNetControl.UserControl1");
OleAutomation automation = new OleAutomation(webControlSite );
webControlSite.doVerb(OLE.OLEIVERB_UIACTIVATE );
int dispIdMember2 = 101;
webControlSite.addEventListener ( dispIdMember2, new OleListener() {
public void handleEvent(OleEvent event) {
// Do something here....
return;
}
);
Partial C# code...
using System.Runtime.InteropServices;
namespace MyNetControl
{
public delegate void ClickEventHandler();
[Guid("47C976E0-C208-4740-AC42-41212D3C34F0"),
InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface Events
{
[DispId(101)]
void ClickEvent();
}
[Guid("9E5E5FB2-219D-4ee7-AB27-E4DBED8E123E"),
ClassInterface(ClassInterfaceType.None),
ComSourceInterfaces(typeof(Events))]
public class UserControl1 : System.Windows.Forms.UserControl
{
event ClickEventHandler ClickEvent;
private void button1_Click(object sender, System.EventArgs e)
{
if (ClickEvent != null)
{
ClickEvent();
}
else
{
MessageBox.Show("oups!");
}
}
}
}
