I can't explain why this happens, but it's good for me to work using 1st case.
Thank you again for your wonderful help!

Sorry, my bad the very last code must be like this:
oSset.Select mode, , , dxfTyp, dxfDat
MsgBox "Third method: " & vbCr & "Selected using ""acSelectionSetAll"" mode " & oSset.Count & " blocks" & vbCr & _
"[ in the current DRAWING ]"
