Exception Trapping

[Other Languages]

Languages Focus

A common usage of exception handling is to obtain and use resources in a "try-it" block, deal with any exceptions in an "exceptions" block, and release the resources in some kind of "final" block which executes whether or not any exceptions are trapped.

VB.Net: Try...Catch...Finally

VB.Net uses a try...catch...finally statement to trap for errors.

Try

Finally
End Try

Syntax Example:

Try
  Dim y As Integer = 0
  y = 1 / y
Catch
  MessageBox.Show("you cannot divide by zero")

End Try
