Stella,
Retrieval stops right away for me . If your program has ,
dbcancel() command in retrieverow event, then it will return the first row .
But as I have mentioned, have dbcancel( ) in clicked even of the command
button. ANd then the retrieval stops right away.

This is a snap shot of my retrieval window -)
This is the message , when retrieval stops -)

This is how I finally implemented it also, but as Russ mentioned, "Cancel take
place at the end of the end of the select during the fetch", so it does not
cancel right away and still returns first row or 'no rows returned'.
Thanks,
Stella

This works fine for me. This is how I have implemented it.
I have a progress window with cancel retrieval command button. The window
is
opened in retrievestart event. It's closed in retrieveend and clicked event
of
the cacel button.
In constructor event of n_cst_appmanager nvuo, I have
SQLCA.dbParm = "Async = 1"
In clicked event of cancel query command button,
window_name.data_window.dbcancel()

For long waits you are not supposed to use an hourglass, but instead some
sort of progress window.

You have a point, but imagine a long retrieve when rows do not come back
right
away and user sits in front of the computer and there is no activity and no
hourglass. Hourglass indicates that there is process running. I have not
decided yet, but as was suggested, my best bet could be a popup window with
Cancel button.
Thank you,
Stella

It doesn't make sense to me that you would want to show an hourglass pointer
at a time when a user is allowed to click on a button. The hourglass
pointer is an indication that the user must wait for an operation to
complete before they can do anything.
We've implemented cancelable retrieves in the past, and were happy to see
the hourglass disappear when it did. Are you sure you really want to do
this?
BTW, I'm not trying to get into a philosophical argument here. I respect
any opinions that oppose mine on this. No need to straighten me out.
Thanks.

Have you tried to put SetPointer(HourGlass!) in the retrieveRow event
itself?
