[WD12] Use of hQueryBreakable

Hello,

Can anybody tell me how to use 'hQueryBreakable' in HExecuteQuery and HExecuteSQLQuery. I hoped I could break the query by pressing <ESC> but there is no reaction or I get a Windows-error (Tell microsoft...). Is there a way to catch the <ESC> and let the user confirm the aborting or let the query continue?

I hope I made myself clear.

I would place the HExecuteXXX call within an exeption to get more information.
likewise:
WHEN EXCEPTION IN
HExecuteXX)
DO
//Code used to process the exception
Error( ExceptionInfo(errCODE) )
ExceptionEnable()
END

to figure out what's going on.

Hello Björn,

Thanks for your answer. Unfortunately this is, as far I can see, not solving mine problem. The HExecuteXXX runs a query and comes back with the result of with an error. You are right, it is possible to trap that error. But I need a way to abort the execution of a query by pressing <<Escape>> AND I want the <<Escape>> to be confirmed before realy stopping the query or continue the query.

Should I start the query in a thread or is there another way of doing this?

Pressing the Esc key abort the execution of the query
I'm still using good old WD8

Hello Bart,

Is it? And if so, can I prevent that or better can I continue the query after a confirmation?

Hello Louis,

I don't think so. Pressing Esc aborts the query immediately.

Kind regards,
Bart
