- Hi MacAppers,
-
- We are having a problem with specifying user alerts on failures.
-
- 1. We could not find a way to specify what is substituted for ^0 or ^1 in case
- of a phGenError.
-
- 2. When using msgAlert as the high word in the 'message' parameter, do we have
- to set the 'error' parameter to something specific?
-
- 3. Currently, the error messages are displayed in windows put up by the Toolbox
- call 'Alert', which prevents windows laying behind the alert from updating. It
- would be nice to have the error message displayed in a window provided by
- MacApp.
-
- 4. Under some circumstances we don't want to have an error message displayed in
- case of a failure. However, we do want to have all the failure handlers have a
- chance to execute.
-
- 5. Has there been any thought to making changes to the these aspects of the
- failure handling mechanisms in the final release? For example, the fact that
- the error field is used for FailMemErrors, FailResErrors, and also used to
- construct ^0 and ^1 makes it difficult to understand. Basically, the error and
- message fields together, as they are used and defined now, are difficult to
- understand and extend for our own uses.
