Never mind the race condition was my coding problem. I added variables in the STA for the ActiveXComponent and its DispatchProxy. I accidentally initialized them in the variable declaration and in the OnInit. Initializing only in the OnInit seems to fix the problem.

OK, that seemed to be the problem. I put the code to create the object inside an STA, added a DispatchProxy and am now getting events.
But I am seeing weird behavior with sometimes getting events and sometimes not. I'm thinking it was a race condition between the STA thread and my main thread, but everything I try, I still sometimes don't get my events.

I have determined that when DispatchEvents is created that SAPI is calling the EventProxy's QueryyInterface to check if it has that interface, but the invoke is never called.
I am wondering now if the problem may be that it is using a technique I have seen elsewhere where it requires a windows message pump to be implemented by the thread that does the initialization. I have seen this before...

I am trying to use JACOB to interface with Microsoft SAPI. I can make the calls into SAPI, but I seem to be completely unable to receive events from SAPI.
Here is some test code I put in an excel worksheet with a button and a text box to test events in visual basic:
Dim WithEvents Voice As SpVoice
Private Sub CommandButton1_Click()
Set Voice = New SpVoice...

Hi all,
I have an application with many COM functions that return an SCODE to indicate success/fail.
However, the problem is that the following 2 instructions always print null, even when SCODE !=0.
Variant ret = Dispatch.call(myDispatch, "myFunction");
System.out.println(ret);
Note that other functions that return a short work fine.
Any ideas?
Hans.

Hi.
I have a small programme which makes use of the Desktop.browse() method. I added some functionality through Jacob, and now the invocation of Desktop.browse() throws an IOException with the message: "Error message: The requested lookup key was not found in any active activation context."
Everything works again as soon as I disable any Jacob functionality (and not load the...
