Chapter 9 - Structured Error Handling

Another potential "gotcha" with Try ... Catch blocks can be illustrated by a modified version of our Divide by Zero example. Suppose you decided to change the program so the values of X, Y, and Z that caused the error would be displayed using the Debug.WriteLine statement. You might try coding it this way:

~~~~~~~~~~~~~~~~~~~~~~~~~
Try
   ' The traditional Divide By Zero error
   Dim X, Y, Z As Integer
   X = 1 : Y = 0
   Z = X / Y
Catch ex As Exception
   Debug.WriteLine("exception using X, Y, and Z values" _
   & vbCrLf & vbTab & X & Y & Z)
End Try
~~~~~~~~~~~~~~~~~~~~~~~~~
