This is from a post I made on August 5.

Joe ...

Option Explicit

Public Sub Test()
Dim Pt1 As Variant
Dim Pt2 As Variant
Dim Sset As AcadSelectionSet

Pt1 = ThisDrawing.Utility.GetPoint(, "Select the First Point")
Pt2 = ThisDrawing.Utility.GetPoint(, "Select the Second Point")

'create Sset object first
Set Sset = ThisDrawing.SelectionSets.Add("Sset")

Sset.Select acSelectionSetCrossing, Pt1, Pt2

MsgBox "Count = " & Sset.Count

'get rid of selection set
Sset.Delete
Set Sset = Nothing
End Sub

one way is to replace

Set Sset = ThisDrawing.SelectionSets.Item("Myss")
If Sset Is Nothing Then
Set Sset = ThisDrawing.SelectionSets.Add("Myss")
Else
Sset.Clear
End If

with

On Error Resume Next
ThisDrawing.SelectionSets.Item("Myss").delete
On Error GoTo 0
Set sset = ThisDrawing.SelectionSets.Add("Myss")

also
Form1.txtbox1.Text = Str(Sset.Count)
might be needed

Hi kulfi,

If you want to be a programmer, you are going to have to learn to do
some work and think for yourself.

Why do you expect every time you clipboard something together that
readers of this newsgroup are going to do the work for you?

I suggest you step through this code yourself with the F8 key and find
the errors and THINK about what may be causing them. Then try to fix
them yourself if you can. That way you will learn something.

If you are really stumped then post an explanation of what you did to
fix your problem and make it easier for others to help you.

Admittedly the error in the line:

ThisDrawing.SelectionSets.Item(Sset).Delete

may prove hard to find as you are bypassing the error in it with the line:

On Error Resume Next.

Look at the sample code you were given by Cadger and fix this error
yourself before moving on the the errors of logic and common sense in
the rest of the code. All of these will be obvious as you step through
the code.

Regards

Laurie Comerford
