DocumentExtension.CloseAndDiscard is asynchronous

[AubelecBE]

i need to close and discard a document.

i use the right command but after this, i need to open the same document when the user say YES to do this

but my code in acad 2010 for fine not in acad2014.

Try

   DocumentExtension.CloseAndDiscard(Doc)

Catch ComEX as COMException

End Try

.....

If msgbox(.....) = vbYes then

 DocumentCollection.open(....)

.....

with this i have when i quit my prog.  2 docs open with the same name    Test.dwg:1   and Test.dwg:2

Test.dwg is not closed when i send the Open command.

Another question : i need to catch the COMException. if i dont, acad show me a msgbox with continue button and stop button saying, the ComException is not handle in the code....

So how is the best use of this command.

PS : i use the commandfrag session  (my code works fine in acad2010 when i use the framework3.5 and good dll.

Here is the open 

Public Sub OpenDrawing()
Dim strFileName As String = "C:\campus.dwg"
Dim acDocMgr As DocumentCollection = Application.DocumentManager

If (File.Exists(strFileName)) Then
acDocMgr.Open(strFileName, False)
Else
acDocMgr.MdiActiveDocument.Editor.WriteMessage("File " & strFileName & _
" does not exist.")
End If
