Hi,
I need your help,
in Autocad by a sub in vba. I try to delete some text by a windows selection on the layout tab. The zone of my selection will be always the same.
My selection does'nt work. What am I forgetting?
After, Ii'm gonna have to insert a text at a special point. Could you give me some hint to write this code?

Thanks
Joh

Private SubDelete()
 
    Dim startPoint(0 To 2) As Double
    Dim endPoint(0 To 2) As Double
 
    startPoint(0) = 34.93151714#
    startPoint(1) = 3.30691694#
    startPoint(2) = 0#
 
    endPoint(0) = 42.058499#
    endPoint(1) = -0.0687933#
    endPoint(2) = 0#
 
    On Error Resume Next
     objSelection.Select acSelectionSetWindow, startPoint, endPoint
     objSelection.AddItems 
    objSelection.Erase

1) Don't make the sub-private unless you need to. That's a little more indepth than we'll want to get into here.

2) Dimension and set a new Selection Set object. Here, I'm looking to see if the selection set name already exists and if it does, I clear it or it's contents. If it doesn't exist, I then create it.

3) AddItems method is not used. This is for adding individual items to an existing selection set.

If this still doesn't work, here's a few things to check, are you in the proper page you're trying to select in?

Have you manually tried drawing a box using the coordinates in your code? This might flush out a problem if it's not where you think it is, if the UCS is different than you expect, etc.

Add code to zoom out slightly from those coordinates. When you select via Window/Crossing, etc., AutoCAD translates the screen pixed coordinates into the graphical coordinates you specified. If those coordinates (the object you are trying to select) are outside the drawing editor, you're not going to be able to select it as AutoCAD ignores coordinates once outside the drawing editor. If it watched all the coordinates, on-screen selection would take forever because AutoCAD would have to continuously check the entire drawing, not just what's on screen. It's one of many ways AutoCAD keeps it's performance up.
ublic Sub SSDelete()
 
    Dim objSelection As AcadSelectionSet
    Set objSelection = ThisDrawing.SelectionSets.Item("SS1")
    If objSelection Is Nothing Then
        Set objSelection = ThisDrawing.SelectionSets.Add("SS1")
    Else
        objSelection.Clear
    End If
    
    Dim startPoint(0 To 2) As Double
    Dim endPoint(0 To 2) As Double
    
    Dim pts As Variant
    Dim pte As Variant
    
    startPoint(0) = 34.93151714
    startPoint(1) = 3.30691694
    startPoint(2) = 0#
    endPoint(0) = 42.058499
    endPoint(1) = -0.0687933
    endPoint(2) = 0#
    
    objSelection.Select acSelectionSetWindow, startPoint, endPoin
    objSelection.Erase
End Sub
