Automatisk mail fra Excel & sikkerhedsbesked

Har lidt problemer med denne kode.

Sub Mail_ActiveSheet()
'Working in 2000-2007
    Dim FileExtStr As String
    Dim FileFormatNum As Long
    Dim Sourcewb As Workbook
    Dim Destwb As Workbook
    Dim TempFilePath As String
    Dim TempFileName As String
    Dim OutApp As Object
    Dim OutMail As Object

    With Application
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    Set Sourcewb = ActiveWorkbook

    'Copy the sheet to a new workbook
    ActiveSheet.Copy
    Set Destwb = ActiveWorkbook

    'Determine the Excel version and file extension/format
    With Destwb
        If Val(Application.Version) < 12 Then
            'You use Excel 2000-2003
            FileExtStr = ".xls": FileFormatNum = -4143
        Else
            'You use Excel 2007, we exit the sub when your answer is
            'NO in the security dialog that you only see  when you copy
            'an sheet from a xlsm file with macro's disabled.
            If Sourcewb.Name = .Name Then
                With Application
                    .ScreenUpdating = True
                    .EnableEvents = True
                End With
                MsgBox "Your answer is NO in the security dialog"
                Exit Sub
            Else
                Select Case Sourcewb.FileFormat
                Case 51: FileExtStr = ".xlsx": FileFormatNum = 51
                Case 52:
                    If .HasVBProject Then
                        FileExtStr = ".xlsm": FileFormatNum = 52
                    Else
                        FileExtStr = ".xlsx": FileFormatNum = 51
                    End If
                Case 56: FileExtStr = ".xls": FileFormatNum = 56
                Case Else: FileExtStr = ".xlsb": FileFormatNum = 50
                End Select
            End If
        End If
    End With

    '    'Change all cells in the worksheet to values if you want
    '    With Destwb.Sheets(1).UsedRange
    '        .Cells.Copy
    '        .Cells.PasteSpecial xlPasteValues
    '        .Cells(1).Select
    '    End With
    '    Application.CutCopyMode = False

    'Save the new workbook/Mail it/Delete it
    TempFilePath = Environ$("temp") & "\"
    TempFileName = "Part of " & Sourcewb.Name & " " _
                & Format(Now, "dd-mmm-yy h-mm-ss")

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    With Destwb
        .SaveAs TempFilePath & TempFileName & FileExtStr, _
                FileFormat:=FileFormatNum
        On Error Resume Next
        With OutMail
            .To = "test@test.dk"
            .CC = ""
            .BCC = ""
            .Subject = "This is the Subject line"
            .Body = "Hi there"
            .Attachments.Add Destwb.FullName
            'You can add other files also like this
            '.Attachments.Add ("C:\test.txt")
            'Display
            .Send
        End With

        On Error GoTo 0
        .Close SaveChanges:=False
    End With

    'Delete the file you have send
    Kill TempFilePath & TempFileName & FileExtStr
    SendKeys "%{s}", True
    Set OutMail = Nothing
    Set OutApp = Nothing


    With Application
        .ScreenUpdating = True
        .EnableEvents = True
    End With
End Sub


Koden virker kun hvis Outlook er starter op. Hvis Outlook ikke er startet op stopper den ved koden.

    Set OutMail = OutApp.CreateItem(0)


Har sat reference til outlook 11 object libary.

Iøvrig hvordan kan man undgå at der ikke poppe en sikkerheds besked op, som siger at der blever sendt en fil, som kan indeholder virus.... ; hvordan kan man undgå denne sikkerhedsbesked?
