OutOfBounds ErrorPosted: Thu May 03, 2012 10:57 pm Joined: Thu May 03, 2012 10:51 pm Posts: 1 Hello. I recently got the trial of real software and i tried out a few tutorials. i was testing out my finished URL Manager from the tutorial and when my URL list box is empty, and i hit delete, the application will crash because of an unhandled OutOfBoundsException. It states "An exception of class OutOfBoundsException was not handled. The application must shut down. Is there any way i can stop this and make a pop-up window stating "There are no URL's to delete"? Im new to coding and real software. Top amitavak Post subject: Re: Help Please.

Like if ListBox1.ListCount > 0 Then //Your delete code goes here Else MsgBox "There are no URL's to delete" End if You can also disable the delete button first and enable it only when there is any row selected. In ListBox change event, you can write if me.SelCount >= 1 Then //Enable the button Else //Disable the button End If you can always handle the exception by using a "Try...catch" block or "Exception" block. _________________ Amitava Real Studio 2011 Release 4 Windows 7 (32 bit) Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Page 1 of 1 [ 2 posts ] -- Over 1500 classes with 29000 functions in one REALbasic plug-in collection.
