When the element message is not available, the application will crash. Thus I like to know if there is any way to check if the element is available before i read its data. in php for exmaple i have a function isset to check things like this. or do i need to work with exceptions? i would do, if there is no other way. spol Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Page 1 of 1 [ 1 post ] -- Over 900 classes with 18000 functions in one REALbasic plug-in.
