    In a module, I write a SUB() , for example:


    Sub aipr()
    .........

    End Sub


    But, sometimes this aipr() running would occur ERROR. So, I want to put an
    ERROR OPERATION sentence inside this sub, How should the VBA be?

    Thanks!

    For example:

    '----- start of example code -----
    Sub aipr()

    On Error GoTo Err_Handler

    ' ... main body of code ...

    Exit_Point:
    Exit Sub

    Err_Handler:
    ' Special code to handle error number 2501
    If Err.Number = 2501 Then
    ' We'll ignore this one and resume at next statement
    Resume Next
    Else
    ' Display a message and exit.
    MsgBox Err.Description, vbExclamation, "Error " & Err.Number
    Resume Exit_Point
    End If

    End Sub
    '----- end of example code -----

    In the VB Editor, search the help for "error handling".
