bail out

What's the best way to handle a "Cancel" in a dialog box? I'd like the script stop running if cancel is chosen.

My current dialog handler looks something like this:

PROCEDURE Dialog_Handler(VAR item :LONGINT; data :LONGINT);

BEGIN

CASE item OF

SetupDialogC:

BEGIN

Set Stuff....

END;

1:

BEGIN

Get Stuff.....

END;

END;

END;

Is it as simple as

0: ______________(Some command that means stop);

Thanks!

2: would be the event of the "Cancel" Button but you really want to check the return value from RunLayoutDialog call outside of the dialog handler.

If it's not 1 then the user canceled or closed the dialog without hitting the OK button.

There are typically 3 default IDs used by the dialog.

1: OK Button

2: Cancel Button

3: Help Box

so your first control should be 4.

Thanks, Kevin.

Is there a command (other than goto) that will skip the rest of the code?

No. GoTo is just about it.

In reality you should structure the code so that is is in an If Then Else statement after the dialog is finished.

If RunLayoutDialog = 1 then

Do Stuff

else

Do Nothing

Does the first argument of the dialog handler retain its value outside the dialog handler?

No, It's only valid inside the dialog handler.
