Sometimes, your system may return an error code that indicates the troubleshooting application. This error can have various reasons. g.AppleScript provides a tool for fine-tuning how you receive and handle individual errors. It is always necessary for a script to handle this particular error and others not. You can usually catch the error, check the error number you are interested in, and use the bug report to make sure you re-report other bugs.

What is the best way to get an error message from an Apple App?I have configured iCal to work at night. Since additional events occur on the same night, I sometimes get an "Action" blah blah blah "found an error" message. Is there a way (using Applescript) to (1) forget about the error and let the program continue, or (2) click the important OK on error and restart the application? end if |
try |
install sumList up to 1, iii, 5 |
set listTotal to SumIntegerList from sumList |
when decrementing the error number errMsg errorNumber |

Error Handling: Using AppleScript try
on error
. The code that may well cause the error is in this try
block, and all of the error handling code is often in the on error

is closed with end try
.
foo
is usually undefined, so it generates great errors. If an error occurs, a dialog box appears.
Try
Guilt Ugh"An alarm has occurred" in the display dialog.End of attempt
All error messages and error numbers can be retrieved using over error errormsg number errorno
, where errormsg, but also errorno are the variable names for error messages and error numbers.
