Hi,
Using the following VBA code with ObjectDBX Library, it seems impossible to detach (or delete) a XREF block from the Blocks collection even after having previously deleted all the references to the block. Has anyone any idea or suggestion?
In addition:
1) The same code WITHOUT the ObjectDBX library
-succeeds if references exist in only one layout (fails with ObjectDBX library)
-fails if references exist in mulriple layouts
2) After having removed the references with this code, opening the file in AUTOCAD removes the block from the blocs collection!!! (but not re-opening it with ObjectDBX Library!)
Sub DetachXrefTest()
Dim oLayout As AXDBLIB.AcadLayout
Dim oBlock As AXDBLIB.AcadBlock
Dim oRef As AXDBLIB.AcadExternalReference
Dim oEntity As AXDBLIB.AcadEntity
Dim vFileName As Variant
Dim ODBX As ODBXClass
'*** SUMMARY of ODBXClass also usable in all VBA interface (EXCEL VBA, WORD VBA,...) *******

'Private AxDbDoc As AXDBLIB.AxDbDocument
'Private AcadApp As AcadApplication
'Private AcadWasNotRunning As Boolean
'Private Sub Class_Initialize()
' On Error Resume Next

' AcadApp.Visible = False 'Make it not visible

' On Error GoTo 0
' 'Get interface object for all ObjectDBX functions and link it with the
