Ideal would be to save in a new file the worksheet you want to send and pass the complete path as a parameter to this function, following the generic example I made as a template:
Sub enviaPlanilhaAtiva()
Dim oOutlook As Object
Dim oEmail As Object
Dim wbAtual As Workbook
Dim sNomeArquivo As String
Dim sLocalTemp As String
Application.ScreenUpdating = False
Set oOutlook = CreateObject("Outlook.Application")
Set oEmail = oOutlook.CreateItem(0)
sLocalTemp = "C:\temp\"
' Copia a planilha ativa e salva em local temporário
ActiveSheet.Copy
Set wbAtual = ActiveWorkbook
' Aqui você define qual planilha deve ser gravada
sNomeArquivo = wbAtual.Worksheets(1).Name
On Error Resume Next
Kill sLocalTemp & sNomeArquivo
On Error GoTo 0
wbAtual.SaveAs FileName:=sLocalTemp & sNomeArquivo
With oEmail
'.To = "[email protected]"
'.Subject = "Assunto"
'.body = "Corpo do e-mail"
.Attachments.Add wbAtual.FullName
.Display
End With
'Deleta o arquivo temporário
wbAtual.ChangeFileAccess Mode:=xlReadOnly
Kill wbAtual.FullName
wbAtual.Close SaveChanges:=False
Set oEmail = Nothing
Set oOutlook = Nothing
End Sub
I hope I have helped!
