when I try to run this program I get a "Automation Error, Catastrophic Failure" error, stopping at the "for each ent in sset" like, can someone please help?

Dim sset As AcadSelectionSet

Private Sub UpdateFields()
    edtCount.Text = sset.Count & " Objekte"
    btGo.Enabled = (sset.Count > 0)
End Sub

Private Sub btGo_Click()
  UserForm1.hide
  Dim nowpt As AcadPoint
  Dim nowtx As AcadText
  Dim nowmtx As AcadMText
  Dim newpt(1 To 3) As Double
  Dim ent As AcadEntity
  For Each ent In sset
    If (TypeName(ent) = "IAcadText2") Then
      Set nowtx = ent
      newpt(1) = nowtx.InsertionPoint(0) + edtDX.Text
      newpt(2) = nowtx.InsertionPoint(1) + edtDY.Text
      newpt(3) = Trim(nowtx.TextString)
      ThisDrawing.ActiveLayer = CheckLayer("NEWPOINTS")
      ThisDrawing.ModelSpace.AddPoint newpt
    End If
    If (TypeName(ent) = "IAcadMText2") Then
      Set nowmtx = ent
      newpt(1) = nowmtx.InsertionPoint(0) + edtDX.Text
      newpt(2) = nowmtx.InsertionPoint(1) + edtDY.Text
      newpt(3) = Trim(nowmtx.TextString)
      ThisDrawing.ActiveLayer = CheckLayer("NEWPOINTS")
      ThisDrawing.ModelSpace.AddPoint newpt
    End If
  Next ent
  sset.Delete
End Sub

Private Sub CommandButton1_Click()
    UserForm1.hide
'    For I = 0 To ThisDrawing.SelectionSets.Count - 1
'        ThisDrawing.SelectionSets(I).Delete
'    Next I
    Set sset = ThisDrawing.SelectionSets.Add("MySetMP")
    sset.SelectOnScreen
    UpdateFields
    UserForm1.Show
End Sub

Private Sub CommandButton2_Click()
    sset.Clear
    UpdateFields
End Sub

Private Sub CommandButton4_Click()
    Me.hide
End Sub

Hi simtech2007,

I see a couple of problems when I try to run this macro in 2000i.

edtDX.Text, edtDY.Text are not defined before use - at least in the code posted,

If (TypeName(ent) = "IAcadText2") Then

should be

If TypeOf ent Is AcadText Then

"Automation Error, Catastrophic Failure" error <-- may be because the sset object has not been created, check to see if it exists before use

YOU WON....

not because it's right, but I've found out that the catastrophic error was just a problem of AutoCAD itself, i.e. re-install and it's ok :)

but since you're the first who answered, you're the winner
