Escape user dialog

Hallo all together,

my problem is the escape from a user dialog in a report.

I've created a dialog window in my report similar to the example on the help side "Report class DialogObject". I've adapted it to my report as a single side dialog and it works, excepted one feature. I can click "OK" and the dialog ends and I can click "Escape" and it also ends.

But how can I read in my report, which button has finalized the dialog?

Therefore I could'nt find any notes in the help side.

I wold be happy if is somebody who can help me.

Many thanks.
