error runtime messages when open file

When I try to open a file which is not currently closed by another program (ex : a log of a backup exec program), I have a runtime error.

I would like to capture the error message with my open command.

Ex :
 Open ch_origine + nom For Input As #1
 
'Here I want to know if an error has been met, not to do the rest of code.
       
 Do Until EOF(1) Or dejafait
...

Thank you for your answer, and sorry for my trivial questions.

Private Sub Command1_Click()
On Error GoTo trap
Open ch_origine + nom For Input As #1
On Error GoTo 0   'turn off error trap

Rem your code

Close #1

Exit Sub

trap:

    MsgBox "Error on open"

End Sub

OR DO THIS

Private Sub Command1_Click()
On Error Resume Next
Error.Clear
Open ch_origine + nom For Input As #1
If Error.num <> 0 Then

    MsgBox "Error on open"

Else

    On Error GoTo 0   'turn off error trap

    Rem your code

    Close #1

End If

End Sub
