Help using AEWsetunsol() with PowerBuilder 7 on Nt4

Question

I am trying to use AEWsetunsol() with Powerbuilder 7 on WinNT 4 (sp6a) or Win2000.
Can anyone help with regards to what we have to do in PB to get this to work?
Please be explicit.
Thanks in advance.

Got it working but had to write a tpinit() wrapper in a DLL in order to get it
to work.
The wrapper function allocated the TPINIT buffer and populated the structure with
appropriate usernames/passwords (none in my case) but we set the 'flags' field
to 1 (notify by signal). [Powerbuilder does not handle structures terribly well
I am led to understand]
If we did not do this, the AEWsetunsol() did not work.
The code window open is as follows :-
// pb_SetLoginInfo() is custom written DLL function - simply
// allocates the TPINIT buffer and populates it.
// fields in same order as TPINIT buffer
If (pb_SetLoginInfo("", "", "", "", 1, 0, "") < 0) Then //flag set to 1 - TPU_SIG
indicating unsolicited notification selected by signals
     messagebox("Error", "Fail pb_SetLoginInfo()")
     return
End If     
// pb_tpinit() is custom written DLL function - simply calls tpinit() with the
structure populated by pb_SetLoginInfo()
IF ( pb_tpinit() < 0) Then //call tp_init from user defined external dll
     messagebox("Error", "Fail tpinit()")
     tpterm()
     return
End If
We wanted to be notified by PBM_CUSTOM68 (Powerbuilder custom event 68)
Then, we called the AEWsetunsol as follows :-
//start subscribing to event
il_windowHandle = Handle(THIS)
//set event to trigger when receive unsolicited message
IF (AEWsetunsol(il_windowHandle, (1023+68)) < 0) Then //the (1023+68) indicates
the event id for pbm_custom68
     messagebox("Error", "Fail AEWsetunsol()")
     tpterm()
     return
End If
We then setup a custom pb event to receive these events, subscribed to an event
and off we went.
Now, if we could only convince the Tuxedo 8 WS DLL to work with Powerbuilder (rather
than crashing on APP exit)
Hope this helps someone.
