We are trying to use the RegisterNotificationClient in an
Xtra to capture couple windows messages from an external DLL.
I basically have two questions:
1. Is using RegisterNotificationClient the right way to
capture windows messages from an xtra?
2. If the answer to 1 is yes, then I have another question as
when we try to set up the parameters for the
RegisterNotificationClient I have a misstmatch in the nid, second
parameter to specify the id of the message to be captured. I have
for windows an integer constant, but the nid param expects a GUID
