VBA CODE ERROR / New collection problem..

hello..

I am using "autocad2006".

I want to know the number of lines and length of lines drawn at "current layer".

But it didn't work properly. I don't know why.

Please help me about below code.

Sub LineSelect()

Dim mode As Integer

Dim retval As New Collection

Dim gpCode(0) As Integer

Dim dataValue(0) As Variant

Dim ssetObj As AcadSelectionSet

Dim tempent As AcadEntity

With ThisDrawing

gpCode(0) = 0: dataValue(0) = "LINE"

mode = acSelectionSetAll

On Error Resume Next

If .SelectionSets("SELECT") Then .SelectionSets("SELECT").Delete

On Error GoTo 0

Set ssetObj = .SelectionSets.Add("SELECT")

ssetObj.Select mode, , , gpCode, dataValue

Dim idBlock As Long

idBlock = ThisDrawing.ActiveLayout.Block.ObjectID

Dim i As Integer

For i = 0 To ssetObj.Count - 1

If ssetObj(i).OwnerID = idBlock Then

retval.Add tempent

End If

Next i

MsgBox retval.Count 'number of lines at current layout

Dim Eac As AcadLine

For Each Eac In retval

MsgBox Eac.Length 'ERROR

Next Eac

End With

End Sub

thank you

I think the problem is that “tempent” in this line has never been set to a value.

retval.Add tempent

SEANT

I think so.. I will try again.

thank you..
