Do you always avoid On Error Resume Next? (VB Only)

Never use On Error Resume Next in VB (and VB.NET) projects.
If an error occurred, On Error Resume Next will hide the error and things can go very haywire! In .NET, stop using the On Error syntax and use the try-catch exception syntax for better structural exception handling.
In VB/VBA you should use On Error Resume Next with line of comment and after an offending line of code there should be statement On Error GoTo 0 to reset Errors collection.
Private Sub cmdSelect_Click()
Dim varTemp As Variant
On Error Resume Next
varTemp = columnADOX.Properties("RelatedColumn").Value
.
....many lines of code...
.
intRoutesPerDay = 2
End Sub
Bad Example – Bad code
Private Sub cmdSelect_Click()
Dim varTemp As Variant
On Error Resume Next
'Sometimes there is no related column value
varTemp = columnADOX.Properties("RelatedColumn").Value
On Error GoTo 0
.
....continuing code...
.
End Sub
Good Example – Good code
