[ireferpesa]

I have a management program with which a file sent by mail, the party of running the outlook is great, but when teams do not have outlook express and have only broken and that I have to check if there is me outlook mapi and only use, but that does not go.

Private Sub Enviar_mail()
  'comprobar si esta outlook o outlook express
  Dim fallo As Boolean = False

  Dim Objeto As Object
  ' Crea una referencia al objeto
  Try
    Objeto = CreateObject("Outlook.Application")
  Catch ex As OleDbException
    fallo = True
  End Try

  ' No dío error
  If fallo = True Then
    Dim fila As DataRowView
    Dim STRCod As String

    For Each fila In Me.List_Proyecto.SelectedItems
      STRCod = fila.Item(2)
      AxMAPIMessages1.AttachmentName = STRCod
      AxMAPIMessages1.AttachmentPathName = ruta & "Archivos\" & Me.ComboCliente.Text & "\" & STRCod
    Next

    'lo mandamos con outlook express
    AxMAPISession1.SignOn()
    With AxMAPIMessages1
      WithMAPIMessages()
      .MsgIndex = -1
      .RecipDisplayName = ""
      .MsgSubject = ""
      .MsgNoteText = ""
      .SessionID = AxMAPISession1.SessionID 'MAPISession.SessionID
      .ResolveName()
      .AttachmentIndex = 0
      .AttachmentPosition = 0
      .AttachmentType = 0
      '.Send()
    End With
    AxMAPISession1.SignOff()

  Else
    'Crear una aplicación Outlook.
    Dim oApp As Microsoft.Office.Interop.Outlook.Application
    oApp = New Microsoft.Office.Interop.Outlook.Application()
    
    ' Crear un nuevo elemento de correo.
    Dim oMsg As Microsoft.Office.Interop.Outlook._MailItem
    oMsg = oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem)
    oMsg.Body = "" & vbCr & vbCr
    
    Dim fila As DataRowView
    Dim STRCod As String

    Dim sBodyLen As String = oMsg.Body.Length
    Dim oAttachs As Microsoft.Office.Interop.Outlook.Attachments = oMsg.Attachments
    Dim oAttach As Microsoft.Office.Interop.Outlook.Attachment

    For Each fila In Me.List_Proyecto.SelectedItems
      STRCod = fila.Item(2)
      oAttach = oAttachs.Add(ruta & "Archivos\" & Me.ComboCliente.Text & "\" & STRCod, , sBodyLen + 1, )

      '' Abrir mensaje nuevo
      oMsg.Display()

    End If

End Sub

I wouldn't send email through Outlook at all. As you have already found out, not everyone has it.

Just send an email directly through your application.

On line 58 in the above posted code you have a For Each loop but you do not have an ending "next" to close the loop.

Other than that, I'm not sure how to check if outlook exists on the machine your application is installed on.

I recommend that you avoid using Outlook and use the .NET tools for sending emails. Check out this Quick reference on how to send email using .NET for more information.
