Excel VBA On Error Resume Next, the options are correct but still do not resume

advertisements

I have already checked Tools > Options > General > Error Trapping in VBE - I have set it to both "Break in Class Module" and "Break on Unhandled Errors" and either way it still throws the error. The error is thrown on the line:

Set xlContacts = Workbooks(LocalContactsFilename)

It throws an error saying the subscript is out of range, and I understand that this means the index was not found within the Workbooks collection, this statement is here because usually the file is already open as an addin so I can just get a reference to it through this statement. It is supposed to resume on this error because if the file is not open I open it.

One odd thing I noticed about this- even though this line of code is not accessing any remote files or the network, it only throws this error when I am disconnected from the network. If I open the workbook while connected to the network this error is not thrown.

Has anyone experienced this before? When your options are set to only halt on unhandled exceptions but it halts anyways?

Public Sub openContactsFile()
    On Error Resume Next
    Dim fso As New FileSystemObject
    Dim LocalContactsPath As String
    Dim LocalContactsFilename As String
    Dim LocalContactsShortFilename As String

    LocalContactsPath = wbMyCompanyWorkbook.Names("localContactsPath").RefersToRange.Value
    LocalContactsFilename = Mid(LocalContactsPath, (InStrRev(LocalContactsPath, "\") + 1))
    LocalContactsShortFilename = Mid(LocalContactsFilename, 1, (InStrRev(LocalContactsFilename, ".") - 1))

    'On Error Resume Next
    Application.ScreenUpdating = False

    If Not fso.FileExists(LocalContactsPath) Then
        If MsgBox("The contacts file is not available.  Click Yes to update the contacts now, or No to use the workbook without contact auto-fill capability.", vbYesNo, ThisWorkbook.NAME) = vbYes Then
            SyncContacts
        Else
            GoTo cancelParse
        End If
    End If
    If fso.FileExists(LocalContactsPath) Then
        On Error GoTo catch_no_remote_connection
        If fso.GetFile(LocalContactsPath).DateLastModified < fso.GetFile(wbMyCompanyWorkbook.Names("remoteContactsPath").RefersToRange.Value).DateLastModified Then
            If MsgBox("Your local contacts file appears to be out of date, would you like to download the latest contacts file?", vbYesNo Or vbQuestion, ThisWorkbook.NAME) = vbYes Then
                SyncContacts
            End If
        End If
catch_no_remote_connection:
        If Err.Number = 53 Then Err.CLEAR
        On Error Resume Next
        Set xlContacts = Workbooks(LocalContactsFilename)

        If xlContacts Is Nothing Then
            Set xlContacts = Workbooks.Open(LocalContactsPath, False, True)
        End If
        xlContacts.Sheets(1).Range("A1:CN2000").Sort Key1:=xlContacts.Sheets(1).Range("F2"), Order1:=xlAscending, Key2:=xlContacts.Sheets(1).Range("B2"), Order2:=xlAscending, Header:=xlYes, OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, DataOption1:=xlSortNormal, DataOption2:=xlSortNormal
    End If

    'hide the contacts from view or editing
    On Error Resume Next
    If Not Workbooks(LocalContactsFilename) Is Nothing Then xlContacts.IsAddin = True
    Err.CLEAR
    On Error GoTo 0
cancelParse:
    Application.ScreenUpdating = True
    Exit Sub
End Sub

Thanks in advance for any help with this!


I have had the same (unbelievably frustrating, as far as I can tell inexplicable) problem as you have, but in a different context. I find the best thing to do is to find a work-around. Instead of using error handling as you have, use this instead:

Dim wb As Workbook, _
    xlContacts As Workbook

For Each wb In Application.Workbooks
    If wb.Name = LocalContactsFilename Then
        Set xlContacts = wb
        Exit For
    End If
Next wb

If xlContacts Is Nothing Then
    Set xlContacts = Workbooks.Open(LocalContactsPath, False, True
End If

I would've preferred to code it the way you've done, but it seems there's no choice.
