pop up for a program error

KKANDOTH

 Hi All,

 I want to build a program which has a user alert facility as soon as it find some error while executing. For example if there is a program like this  

procedure(testing()

a = "try"

b = 2

c=a*b

)  This program will find an error at line c = a*b. and throw a *ERROR ..... message in icfb.log. I want to have a pop up window which alert the user as soon as it exit. I am using a try1=errset(testing) now. According to try1 value , (t or nil) i can find if the program executed or not. but it will suppress the error message in ICFB.log

 Thank You,

  • Krishnan,

    This does what you want:

    procedure(myErrorHandler(info)
      hiDisplayAppDBox(
       ?name 'myErrorDialog
       ?dboxBanner "Error occurred"
       ?dboxText info
       ?dialogType hicErrorDialog
       ?buttonLayout 'Close
       ?dialogStyle 'modal
      )
    )

    ilAddTopLevelErrorHandler('myErrorHandler)

    By the way, if you use errset, you can either pass t as the second argument to errset, and then it will still print the error message. Or you can get the message info by accessing errset.errset . For example:

    errset(testing() t)
    *Error* times: can't handle ("try" * 2)

    unless(errset(testing())
      printf("GOT THIS: %L\n" errset.errset)
    )

    GOT THIS: ("times" 0 t nil ("*Error* times: can't handle (\"try\" * 2)"))

    You can find out more on errset.errset in the documentation for errset().

    Regards,

    Andrew.
