80070002 error when interoperating with COM event sink

[jennyq]

hi all,
I am just playing with the event sink sample on MSDN, but I found when I
create the instance in VB client, there is an error saying "method
'myButton' of object 'form1'failed, errorcode is 8007002. I don't know how
to fix it so far.

The sample is
http://msdn.microsoft.com/library/d...e/html/cpconraisingeventshandledbycomsink.asp
I use the c# sample

1) I specified a key file for the library
2) I used regasm and gacutil to export/register the typelib and intall it
into GAC
3) My VB code is almost the same as the sample except I added From_Load, in
which class_initialize is called(actually I am not sure whether this is
right way to do it because of my poor VB knowledge).

Any help are appreciated!

Thanks very much!
Your answer just reminds me that my dll is strong named, so I should use
full name of the assembly.
The error msg Vb reported just made me totally lost.

That's basicly a "File not found" error.

See if it helps to change

[ComSourceInterfaces("EventSource.ButtonEvents, EventSrc")]

to

[ComSourceInterfaces(typeof(ButtonEvents))]

No you shouldn't call Class_Initialize manually. It's like a
constructor, and is called automatically whenever an instance of the
class is created.
