Re: Consuming a .NET event in VBScript

You should ask in a .Net group about that

Added crosspost.
You'll need to end up with a standard
COM dispatch interface for VBS to see it.
I thought that VStudio does it correctly when
applying the settings in the project properties.
I have now set the ClassInterface set to AutoDispatch
for the whole assembly but there's no difference.
From the VBS end, you want to "consume
events" from your "component solution"?
Exactly.
..NET creates the event and VBScript is
supposed to process them.
You have the right setup for creating the object,
but you also need to have an event sub and
you also need to keep the script alive until
the event happens. So either you're missing
two critical things or you haven't posted
all of the code.
This is all of the code there is.
How do I define an event sub?
I thought, defining a sub like X_Resize does it.
Is there anything more to do?
Should the sub accept a certain set of parameters?
How do I keep a script alive?
The error happens before the messagebox "There" appears.
Adding a wscript.sleep(15) right after the CauseResizeEvent
doesn't make a difference.
It's probably some stupid beginners mistake, but
somehow I'm not getting it right.

I'm pretty new to .NET and I am trying to have a VBScript consume an event
created in a .NET component.
I started out with http://msdn.microsoft.com/en-us/library/dd8bf0x3.aspx.
I registered the assembly for COM interop and made it COM visible
(checkboxes in the Visual Studio 2--8 project properties dialog).
This is the .NET Code:
using System.Runtime.InteropServices;
namespace PureEvents
{
public delegate void ClickDelegate(int x, int y);
public delegate void ResizeDelegate();
// Step 1: Defines an event sink interface (ButtonEvents) to be
// implemented by the COM sink.
[GuidAttribute("1A585C4D-3371-48dc-AF8A-AFFECC1B0967")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIDispatch)]
public interface ButtonEvents
{
void Click(int x, int y);
void Resize();
}
// Step 2: Connects the event sink interface to a class
// by passing the namespace and event sink interface
// ("EventSource.ButtonEvents, EventSrc").
[ComSourceInterfaces(typeof(ButtonEvents))]
public class PureEvents
{
public event ClickDelegate Click;
public event ResizeDelegate Resize;
public string getValue()
{
return "Normal method call";
}
public PureEvents()
{
}
public void CauseClickEvent(int x, int y)
{
Click(x, y);
}
public void CauseResizeEvent()
{
Resize();
}
}
}
The VBScript code looks like this:
sub X_Resize
msgBox "Here"
end sub
set BFI=wscript.createobject("PureEvents.PureEvents","X_")
msgBox BFI.GetValue()
BFI.CauseResizeEvent
msgBox "There"
The getValue()-Method gets called properly, so the component itself works.
However, when I call CauseResizeEvent, I get an 80004001 error (method or
process not implemented".
Am I missing anything obvious here?
The script does not run in IIS or internet explorer, it just gets double
clicked and then runs in wscript.exe.
I appreciate any help.
Lots of Greetings!
