Hi,
One of my users see an error message "Unknown transition" in the program.
I can't replicate this issue.
What might be the cause of the error and how to fix it?

Provide some code or a demo. No one can reply to this unless you provide detail.

Using pyschic debugging I would guess that you are running transition effects and setting the TIETransitionType numerically, e.g. Transition := TIETransitionType( Random( n ) + 1 ), where n is not in the range of TIETransitionType

I use
transition = TIETransitionType(random(MAX_TRANSITIONS));
ImageEnView1->RunTransition(transition, duration);

Hi

TIETransitionType( 0 ) is iettNone, which you do not want.

You should use:

transition = TIETransitionType(random(MAX_TRANSITIONS - 1) + 1);
ImageEnView1->RunTransition(transition, duration);

Thanks.
But it could not be the cause of "Unknown transition" error.

Yes, it could, because if you specify the transition type as iettNone, it will fall through to the "Unknown transition" error.
