lockErrorDialogs

set [the]

 lockErrorDialogs to ¬                  trueOrFalse

The lockErrorDialogs property returns or sets whether HyperCard, on encountering an error, presents an error dialog box.

This property defaults to false at idle time, meaning that error dialogs usually appear.

When this property is set to true, HyperCard, on encountering an error, does not display an error dialog box; instead, it sends the message errorDialog errorMessageText to the current card.

ErrorMessageText contains the text of the error dialog box.

Examples

set lockErrorDialogs to true

set lockErrorDialogs to false
